A champion for the rights of workers who have developed pleural plaques as a result of exposure to asbestos in the workplace is Jarrow MP Stephen Hepburn. In a meeting at the House of Commons on Nov. 27, he argued the issue of pleural plaques is “immensely important” to workers and pensioners, and insisted it is the duty of members of both sides of the House to overturn the “disgraceful and unjust decision by the Law Lords to bar this terrible illness from classification as a designated illness for compensation purposes,” according to a report in The Chronicle.

Hepburn also told the Commons that pleural plaques sufferers are 1,000 times more likely to develop a more serious form of asbestos-related cancer. Mesothelioma is a deadly form of cancer that affects the lining of the chest cavity and lungs (pleural) or the lining of the stomach (peritoneal). It may also rarely affect the lining of the heart (pericardial). There is no known cure for mesothelioma.

During the heated debate, The Daily Mirror reports that statistics were revealed that show mesothelioma rates in the UK have nearly doubled in 10 years. According to the news source, hospitals treated 7,349 cases of mesothelioma in the past year, compared to 3,773 cases during the timeframe of 1998-99. The Mirror calls mesothelioma an “asbestos timebomb,” citing the disease’s long latency period.

The Mirror quotes Hepburn as saying, “We’re seeing the legacy of workers exposed to asbestos in the 1960s.”

Shortly after her return, abdominal pain sent her back to the hospital. She was good enough to email me to let me know she had suffered from a condition called illeus, which is when the intestines become paralyzed. She stayed in the hospital in Texas for a few days until finally coming home again on May 13. She said she’s focusing on getting stronger and gaining weight, but is frustrated by the  setback after all her hard work to recover from her surgery.

You can check in on Shanna’s progress by reading her journal on the CaringBridge web site and email her some encouraging words at goddesslorraine@aol.com. I know she’d really appreciate hearing from some folks in the meso community!

There was a fundraiser in her honor last weekend, and there’s an ongoing effort in Texas called “Cooking for the Cure” to help raise money for Shanna’s treatments.  Cheri Travis, who is one of the organizers of Cooking for the Cure, reports Shanna is scheduled for another surgery in August, so fund raising efforts continue.

Cooking for a Cure was started by Cheri and two other friends who like cooking, and wanted to use their interests and talents in the kitchen to raise money for Shanna. They gather at one person’s house and prepare food, which they distribute in exchange for donations.

“It’s really spread by word of mouth of people who buy our food,” Cheri explained in an email to me. “Plus, we have fun doing it and helping raise funds for our friend.”

The group is based near Victoria, Texas, so if you live in that area, check out this unique project!

Cheri said there also is another fund raising benefit in Shanna’s honor planned for September 18 in Victoria. I’ll let you know the details when I have them.

In the meantime, if you live near Victoria and would like to purchase food from Cooking for the Cure, you can email Cheri at cetfrog@gmail.com.

Shanna Kurtz was diagnosed in 1999, at age 20, after suffering from several years of unexplained abdominal pain. Doctors who originally suspected a fibrosis tumor discovered a grapefruit-sized tumor in her abdomen, which was diagnosed as peritoneal mesothelioma.

Shanna’s journal on CaringBridge.org documents her experiences through the last several years as she has fought to keep this cancer at bay. It is heartbreaking to read about someone so young who has to face this experience. In one journal entry from October 2008, she reflects on how it feels when people tell her how strong she is, when she doesn’t have any other choice. She states frankly that she is jealous of people who have the option to choose what they will do with their lives, and reflects on so many doors that are closed to her.

Despite the inevitable depression, Shanna is remarkable. Upon her diagnosis told her only about 20 percent of patients survive beyond a couple of years. Determined to be in that 20 percent, she is beating the odds.

Most recently, Shanna’s journal chronicles a surgery on March 26 in Washington, DC, at the Center for Surgical Oncology at the Washington Cancer Institute, Washington Hospital Center.  Dr. Paul Sugarbaker removed a number of tumors, including one that had covered part of her liver. Following the surgery, the doctor filled her abdomen with chemotherapy medication in a process called postoperative intraperitoneal chemotherapy. The solution comes into contact with areas the tumor has touched, in an effort to erradicate those cells and prevent recurrance.

Shanna was in the hospital for a little over a month, finally returning home to Cuero, Texas, on May 7.

This weekend, there will be a benefit in her honor, to help offset the medical expenses of the surgery. The event will feature a bike ride and barbecue. The bike ride will leave from Grace Lutheran Church in Victoria, Texas, on Saturday, May 16, at 2 p.m., and will be followed by an evening of dancing, an auction, food and music, which will start around 4 p.m. at Lindenau Dance Hall, which is about 33 miles from Victoria. Cost to participate is $30.

If you are in the area, please attend this event!

In addition to the weekend event, there is an ongoing project called “Cooking for the Cure,” in which three friends prepare food in exchange for a donation to help Shanna. In its first month, the project raised more than $1,100.

For more information about Cooking for the Cure or the Shanna Kurtz Benefit Barbecue, or to make a donation to help Shanna, contact Cheri Travis at cetfrog@gmail.com.

According to the report, the study involved 20 patients treated between 2002 and 2004 who received Alimta and Gemzar every 21 days, along with folic acid, vitamin B12 and dexamethasone. Cancer Consultants reports overall response rate was 15 percent, disease control rate was 50 percent, median time to disease progression was 10.4 months and the median survival time was 26.8 months. Additionally, the report notes that toxicities were tolerable.

Cancer Consultants notes that peritoneal mesothelioma makes up less than 20 percent of all cases of mesothelioma, with pleural mesothelioma being more common. Peritoneal mesothelioma is a specific form of mesothelioma that affects the peritoneum, which is the serous membrane that forms the lining of the abdominal cavity.

Pleural mesothelioma is the most common form of the disease, making up about 75 percent of all cases. Pleural mesothelioma affects the outer lining of the lungs and chest cavity.

Because of its relative rarity, there have been few studies of chemotherapy as a treatment for peritoneal mesothelioma, and there are no controlled trials of various treatment options available for peritoneal mesothelioma.

Traditional therapy for peritoneal mesothelioma has involved surgical debulking followed by systemic and/or intraperitoneal chemotherapy.

Cancer Consultants, which delivers educational programs and resources to more than 18 million targeted seekers of cancer information, has been producing and distributing cancer information for patients and professionals since 1998.

The publication notes that this study is one of the first devoted to systemic chemotherapy treatment for peritoneal mesothelioma and as such provides an important baseline for research.

Because of its long latency period – from 20 up to 50 years – mesothelioma usually occurs in older people, age 50 and older. For that reason, Carlisle’s mesothelioma eluded diagnosis early on, with doctors mistaking her symptoms for ailments such as irritable bowel syndrome (IBS), pelvic infection and endometriosis. Doctors were stunned when they diagnosed peritoneal mesothelioma.

Because of her young age, researchers believe Carlisle may have come in contact with asbestos – the only known cause of mesothelioma – in her school, or possibly from a factory yard near her childhood home, which she used as a shortcut on her way to school each day. Asbestos sheets were cut at the yard.

According to the report, about 2,000 people in Britain die from mesothelioma each year, a figure that has doubled since 1992. The paper reports that 90,000 people in the UK will die from the disease, and another 90,000 from other asbestos-related lung diseases.

Additionally, the report says about 200 school workers have died or are suffering from illnesses related to asbestos exposure in schools in Britain, where it is estimated that about 13,000 schools still contain asbestos.

Following her diagnosis, Carlisle worked for mesothelioma and asbestos awareness. Her family requests that donations in her memory be made to the Oldham Cancer Support Centre in Failsworth:

According to Rob Grayson, director of marketing for the Meso Foundation, the event actually started as a purely scientific event, geared toward researchers and scientists, with technical presentations. However, at the time, there were no informational or educational events like it, and they found that patients, families and caregivers wanted to attend.

“Initially, these people would come and sit in on these high-level presentations by scientists, with very technical presentations. We saw the interest and our meeting has now evolved into more of a patient meeting, the scientists speak in more layman’s terms, and we’ve added programs to reach out to people who are also interested in the community of support and the activism that takes place,” Grayson said.

The advocacy element is a new piece of the symposium, added last year when the meeting coincided with debate in the Senate on the Ban Asbestos in America Act, S. 742, sponsored by Senator Patty Murray (D-WA).

“The day we lobbied, they took an administrative vote, and it passed in the Senate. So we’re going back to Washington this year,” Grayson said.

Advocacy efforts this year will include a rallying cry to the House of Representatives to move quickly to pass the legislation in the House, which bans asbestos and provides research funding for mesothelioma. Last week, the Foundation issued an action alert in support of The Bruce Vento Ban Asbestos and Prevent Mesothelioma Act of 2007 (H.R. 3339), the companion to the Senate bill. The bill includes $10 million for mesothelioma research.

“Normally we’d hold the Symposium in a different city each year, but it’s almost the same timing as last year, with the bill pending, this time in the House, so we’re back to Washington,” Grayson explained.

Those attending the Symposium can register to participate in the advocacy efforts, and the Meso Foundation will arrange for them to meet personally with their congressional delegate, and will provide a training session to help advocates prepare for the meeting.

In addition to lobbying for passage of the House bill, Symposium advocates will request that the Senate’s Defense Appropriations Subcommittee maintain, for the second year, mesothelioma’s eligibility to compete for medical research funding from the Department of Defense. In 2007, the DoD appropriated $50 million and included mesothelioma as a research priority for its Peer Reviewed Medical Research Program, effective in the 2008 budget. The Meso Foundation is working for continuing and increasing funds for mesothelioma research in the 2009 defense appropriations bill.

“There currently is no ban on asbestos, so companies can use it however they see fit. We’ve pretty much stopped mining here, but asbestos is still used in about 3,000 products that you could go out and buy right now. Even if we banned asbestos tomorrow, it probably won’t change the rate of sickness for the next 50 years, due to the latency period of asbestos. That’s why the funding for research is so important,” Grayson says. “Advocacy and the call for a ban on asbestos raises awareness, and raises money for research, which is what we need to deal with the illness itself,” he said.

In addition to advocacy, the Symposium again will feature an educational program, with sessions covering topics including Peritoneal Mesothelioma, Pleural Meso Surgical Options, Emerging Therapies, Optimizing Patient Care, and Scientific Advances in Meso Research. Other educational programs will provide instruction on outreach topics including volunteerism, fundraising, peer support and advocacy, to help those who want to make a difference learn how to be most effective.

A Gala Dinner will honor those people living with meso, and recognize outstanding volunteers and advocates for their hard work and dedication to raising awareness. The dinner will feature a unique guest speaker – Seventh grader Lexi Miletto, the granddaughter of Joseph Miletto, who died in 2005 of peritoneal mesothelioma.

Scholarships for Symposium registration fees, as well as for transportation and accommodations, are still available for patients, family members and caregivers who would like to attend. Contact the Meso Foundation at www.curemeso.org or call 805-563-8400 for details.

The Mesothelioma Foundation was started in 1999, by attorney Roger Worthington. Unfortunately, Grayson says, there was an initial stigma because of his association, with people suspicious the Foundation was attempting to gather clients for his firm, so he removed himself from the Board of Directors and the Foundation was re-established as a non-profit, 501(c)3 organization. Today, with 8 staff members, the organization raises $2.5 million annually and funds more than $1 million in research projects.

“Currently, most of our funding goes to seed money to help researchers who have good ideas for treatment to validate their work, and take it to the NIH to get additional funding for the next step of the research,” Grayson explained. “We hope very soon that we’ll be able to fund clinical trials.”

A couple of days ago I wrote about the closest topic I’ve seen along these lines, which still involved ways to find a silver lining in the struggle. Obviously, it’s a very necessary part of such a diagnosis. But it’s still about hope.

But today I came across an interesting essay, penned by Monica Sanford, a graduate student at the University of Nebraska-Lincoln, that is forcing me to look at another reality of mesothelioma. Its title, “Inevitability of death leads to freer living,” was immediately arresting. The author jumped right in with, “I thought I should write about death.” She went on to share that she has recently lost three people very close to her in fairly rapid succession – a paternal grandmother, a maternal great-grandmother, and her dear friend, Marilyn. Marilyn died of peritoneal mesothelioma at age 47.

As she ponders the very different lives and deaths of these people she loved, Monica wonders at a common thread – all knew they were nearing death, two as a result of illness, the other just sensing her time was nearing an end, even sharing with her great-granddaughter just a month before her death that she had walked with God, who showed her a waiting heaven.

That’s a truly unique aspect of this diagnosis. The knowledge, the clarity, the preparation for death. Everyone knows they will one day die, of course, but that day is always a long way off. Illness of this kind brings it into sharp relief.

In the post I wrote a couple days ago about silver linings, most people said the one thing they could credit their disease for was giving them a sense of the value of their time on earth. That knowing their illness was diagnosed as terminal gave them often times a will to fight harder and stay longer, because they saw with new eyes all the things they really wanted before they would be ready to go.

There’s a saying, “live each day as if it was your last.” But in the everyday hustle and bustle, it’s so hard to keep that in mind.

Monica’s essay reflects on faith, traditional Christian faith like that of her great grandmother, as well as her own, different, Buddhist perspective, and observes the different ways that her family members mourn, or celebrate, or deny at a loved one’s passing.

In the end, she finds that, for her, “The one thing I have that helps me cope with death in my life is not faith or family or hope. It is acceptance. Death is. Just like life is. Neither is good nor bad – they just are.”

But still, it hurts to let go.

However, down at the end of the article, you learn that risk begins to drop FIFTY YEARS after exposure ends. The report also says that it looks like men have the highest risk of developing lung cancer 30-39 years after exposure, and women are at highest risk 20-29 years after exposure. Then risk begins to drop. Begins.

The decline refers to pleural mesothelioma. The report says that the risks for peritoneal mesothelioma continue to rise, even 40 years after exposure has ended.

It’s a puzzling article, since it SOUNDS like good news, but then as you read along it doesn’t really sound all that great.

Following is a story that appeared in the Detroit Free Press about the remembrance service, and the mission of asbestos awareness. I will post some stories and images from the conference this week, but I wanted to share this excellent report.

By Amber Hunt, Free Press Staff Writer

For Andrew Manuel, it began with back pain.

But the seemingly benign symptom turned out to be something far more sinister, and within two years, the married father of three shed 65 pounds, underwent surgery to have a lung removed and endured chemotherapy and radiation to no avail.

At 42, he was dead. The killer: mesothelioma, a cancer linked to asbestos.

“When I heard the diagnosis, I said, ‘Meso-what?’ ” said Manuel’s wife, Latanyta Manuel, 45, on Sunday. “All I heard was ‘lung cancer,’ and I said, ‘No, that’s not possible.’ My husband never smoked or drank, but they said this cancer is about asbestos.”

On Sunday, a group of people affected by the deadly disease, which they refer to as “meso” for simplicity’s sake, gathered at the Marriott in downtown Detroit’s Renaissance Center for a remembrance brunch.

The event was sponsored by California-based Asbestos Disease Awareness Organization and the Karmanos Cancer Institute in Michigan.

Some, such as Manuel, had lost loved ones. Others have been diagnosed with the deadly disease themselves.

They gather annually, they said, to support each other and to spread the word about asbestos-related diseases, including lung cancer and asbestosis.

Asbestos is a fiber that for decades was routinely used for fireproofing and insulation.

While the U.S. government has limited its use, asbestos still can be found in many products, including some stuccos, vinyl flooring and even theater curtains, according to the Asbestos Resource Center.

“Asbestos is still being imported. It’s still being put in products,” said Michelle Zigielbaum, whose husband, Paul, has been diagnosed with peritoneal mesothelioma.

By the time he was diagnosed, his stomach was so full of fluid and tumors that “I looked like a pregnant woman,” Paul Zigielbaum said.

The Asbestos Disease Awareness Organization recently conducted a study that tested 250 products off store shelves for asbestos content. A first lab found that 18 of the products contained asbestos.

A second lab confirmed that eight of the products had asbestos, while a third confirmed that five products — including a child’s toy — contained asbestos.

Those gathered Sunday said they and their loved ones got sick in different ways.

Andrew Manuel’s father worked in a pipeline, bringing asbestos back into the home. Paul Zigielbaum said he believes he was exposed secondhand, too, but said he also believes that contact with everyday products contributed.

All blamed aggressive asbestos lobbyists as the reason the United States hasn’t banned the substance altogether.

“It’s disturbing to see how companies and politicians try to cover it up,” said Dwayne Manuel, Andrew Manuel’s 26-year-old son. “This is a preventable disease.”

Latanyta Manuel said she just wants to honor her husband’s wishes and spread awareness about the disease.

“Once it erupts, it just kind of takes over,” she said. “People need to know.”

What is Mesothelioma?

Mesothelioma cancer, or malignant mesothelioma, is an extremely rare disease generally affecting the lining of the lungs, and, more rarely, the abdominal cavity and/or the heart. Mesothelioma cancer is most strongly associated with exposure to asbestos, and can remain latent in those exposed for 30 to 40 years.

There are three types of mesothelioma cancer: pleural, in which the cancer affects the lining of the lungs/chest;  peritoneal, which affects the lining of the abdominal cavity; and pericardial, which affects the lining of the heart.

Pleural mesothelioma is the most common form of malignant mesothelioma, accounting for approximately three out of every four cases. The pleura is defined as the outer lining of the lungs and chest cavity. Pleural mesothelioma typcially has a latency period of 30-40 years or longer.

Peritoneal mesothelioma generally accounts for about 25 percent of maglignant mesothelioma cases diagnosed each year. It can have a shorter latency period than pleural mesothelioma, developing in 20-30 years or shorter. It affects the peritoneum, which is the lining of the abdominal cavity. Peritoneal mesothelioma generally occurs more often in males than females.

Pericardial mesothelioma, which affects the pericardium, the lining of the heart, is extremely rare. This form of malignant mesothelioma is usually fatal, due to its difficulty in diagnosis and treatment. It is generally diagnosed in a very late stage, and surgical or other treatment options are dangerous and difficult.

Mesothelioma in general is fairly rare in the United States. There are an estimated 2,000 to 3,000 new cases of mesothelioma each year in the United States. However, in European countries, especially the UK, as well as in Australia, the rate of mesothelioma is increasing.

For years, mesothelioma was thought to be  rare in people under age 55. Traditionally seen primarily in older men, usually with a background of working in a factory, shipyard, mine or other environment with heavy asbestos exposure, today more and more cases of secondary exposure are being diagnosed, and it is affecting greater number of women.

The average age for someone with mesothelioma used to be around 72, but each year it seems mesothelioma affects younger people, and a greater number of women. Last year, a 3-year-old girl was diagnosed with mesothelioma, stunning the physicians who were treating her.

Mesothelioma is a serious disease. By the time the symptoms appear and cancer is diagnosed, the disease is often advanced. The average survival time is about 1 year. The 5-year relative survival rate is around 10%, but this rate has been slowly improving.

The 5-year survival rate refers to the percentage of patients who live at least 5 years after their cancer is diagnosed. Many of these patients live much longer than 5 years after diagnosis, and 5-year rates are used to produce a standard way of discussing prognosis.

Five-year relative survival rates do not include patients dying of other diseases and are considered to be a more accurate way to describe the prognosis for patients with a particular type and stage of cancer. That means that relative survival only talks about deaths from mesothelioma. Of course, 5-year survival rates are based on patients diagnosed and initially treated more than 5 years ago. They may no longer be accurate. Improvements in treatment result in a more favorable outlook for recently diagnosed patients.

Symptoms of Mesothelioma

Early symptoms of mesothelioma can be very general. Thus, they are often ignored.

Symptoms of pleural mesothelioma (lining of the chest) can include:

* pain in the lower back or at the side of the chest

* shortness of breath

* trouble swallowing

* hoarseness

* cough

* fever

* sweating

* tiredness

* weight loss

* swelling of the face and arms

* muscle weakness

Symptoms of peritoneal mesothelioma (lining of the abdominal cavity) include:

* belly pain

* weight loss

* nausea

* vomiting

* fluid or a lump in the abdomen

Symptoms of pericardial mesothelioma (lining of the heart) include:

* constrictive pericarditis

* pericardial effusion

* cardiac tamponade

* heart failure caused by myocardial infarction

Of course, these same symptoms can also be caused by other minor ailments. But if you have worked with asbestos and you have any of these symptoms, you should see your doctor right away.

Diagnosing Mesothelioma

Diagnosing mesothelioma is often difficult, because the symptoms are similar to those of a number of other conditions.

Diagnosis begins with a review of the patient’s medical history, including any history of asbestos exposure. A complete physical examination may be performed, including x-rays of the chest or abdomen and lung function tests. As a rule, a chest x-ray is not useful in finding mesothelioma early.

One test being studied is a blood test. This test measures the levels in the blood of a certain protein that is higher in people who have lung damage due to asbestos. It is even higher if the person has mesothelioma.

A CT (or CAT) scan or an MRI may also be useful. A CT scan is a series of detailed pictures of areas inside the body created by a computer linked to an x-ray machine. In an MRI, a powerful magnet linked to a computer is used to make detailed pictures of areas inside the body. These pictures are viewed on a monitor and can also be printed.

A biopsy is needed to confirm a diagnosis of mesothelioma. In a biopsy, a surgeon or a medical oncologist (a doctor who specializes in diagnosing and treating cancer) removes a sample of tissue for examination under a microscope by a pathologist. A biopsy may be done in different ways, depending on where the abnormal area is located.

If the cancer is in the chest, the doctor may perform a thoracoscopy. In this procedure, the doctor makes a small cut through the chest wall and puts a thin, lighted tube called a thoracoscope into the chest between two ribs. Thoracoscopy allows the doctor to look inside the chest and obtain tissue samples.

If the cancer is in the abdomen, the doctor may perform a peritoneoscopy. To obtain tissue for examination, the doctor makes a small opening in the abdomen and inserts a special instrument called a peritoneoscope into the abdominal cavity.

If these procedures do not yield enough tissue, more extensive diagnostic surgery may be necessary.

If the diagnosis is mesothelioma, the doctor will want to learn the stage (or extent) of the disease. Staging involves more tests in a careful attempt to find out whether the cancer has spread and, if so, to which parts of the body. Knowing the stage of the disease helps the doctor plan treatment.

Mesothelioma is described as localized if the cancer is found only on the membrane surface where it originated. It is classified as advanced if it has spread beyond the original membrane surface to other parts of the body, such as the lymph nodes, lungs, chest wall, or abdominal organs.

New developments in Diagnosis of Mesothelioma

A recently published report in the Journal of the American Medical Association holds out hope for earlier detection of mesothelioma, a deadly cancer linked to asbestos exposure.

Researchers compared three types of endoscopic collection for accuracy in detecting cancerous cells in the lymph nodes to determine their accuracy.

Typically, doctors use several different techniques to diagnose lung cancers, including mesothelioma. Those techniques include physical exams, chest X-rays, CT scans and surgical biopsies to examine the cells in the lungs and the lymph nodes.

Lung cancer is one of the most common cancers worldwide, and the outcomes are typically unpromising. The low survival rates for lung cancer are often attributed to the difficulty of diagnosing the disease early enough for effective treatment.

This is especially true of mesothelioma, a disease that affects the tissues of the lining between the chest wall and the lungs. Often, by the time mesothelioma is detected, the cancer has reached untreatable stages.

Because of this, researchers are increasingly turning to new methods of detection that may identify deadly cancers at earlier stages when chemotherapy, surgery and other treatments may be effective.

The most accurate methods of diagnosis to date involve collecting cell samples from the lungs or lymph nodes for examination under a microscope. The most common method for collecting these cells is a mediastinoscopy, which is an invasive surgery that involves anesthesia and incision. The surgeon makes an incision at the top of the breast bone and inserts a thin, lighted tube into the chest cavity to withdraw cell and fluid samples.

Mediatinoscopy is typically used to determine whether fluids in the chest cavity contain cancerous cells or asbestos fibers.

In the past few years, doctors have developed less invasive procedures to collect tissue samples from the chest. These procedures use an endoscope, a small medical device that consists of a camera mounted on a flexible tube. Ultrasound probes, needles and other instruments can be inserted through the tube to remove samples for biopsy. These endoscopic procedures are far less invasive than more traditional methods, reducing the risks to patients who undergo them.

In the study reported in JAMA, researchers compared three different procedures using an endoscope, each of them considered minimally invasive:

• Transbronchial needle aspiration (TBNA)

• Endobronchial ultra-sound guided fine needle aspiration (EBUS-FNA)

• Transesophegeal endoscopic ultrasound-guided fine needle biopsy (EUS-FNA)

In each procedure, an endoscope was used to remove tissues or fluids with a fine needle. The researchers then compared the findings among the three methods to determine which was the most sensitive for detecting the presence of cancerous cells in the lymph nodes of the chest.

The study consisted of tests taken on 138 patients in the U.S. who were believed to have lung cancer. Each patient underwent all three procedures in sequence.

The results of the study showed:

- 30% (42) of the patients had malignant lymph nodes

- EBUS-FNA detected 29 of the cancers. TBNA only detected 15

- EUS-FNA and EBUS-FNA used in combination detected 93% of the cancers.

The combination was also able to detect malignancies in patients who would not have been identified by CT scans of the chest. The results of the study suggest that the minimally invasive procedures may be a viable alternative to more invasive standard procedures for evaluation patients believed to have lung cancer.

The lower risks associated with the procedure will make the diagnostic process more comfortable for patients and provide for a shorter recovery time.

New System May Give Lung Cancer Patients Hope

The Associated Press Aug. 31, 2007 http://www.msnbc.msn.com/id/20533486

Thousands more lung cancer patients each year could be offered surgery or other aggressive therapy under a new system that classifies many tumors as more treatable than in the past.

It is the first big overhaul of a decades-old method used to predict survival and help determine whether a lung cancer patient will have surgery, chemotherapy or be treated at all.

The new guidance is to be presented at a conference of lung cancer specialists in Seoul, South Korea, that starts Saturday. It is expected to be adopted by policy-making groups in the next year. Lung cancer is the world’s top cancer killer, claiming 1.3 million lives each year.

In the United States, 213,380 new cases and 160,390 deaths from the disease are expected this year. Nearly 60 percent of people die within one year of diagnosis, and nearly 75 percent die within two years, American Cancer Society statistics show.

In treating it, doctors use a formula called tumor staging. It is based on a tumor’s size, how far it has spread and other factors to predict a patient’s survival odds and to guide treatment.

More precise sorting

The current system was developed from about 5,000 tumor samples from University of Texas M.D. Anderson Cancer Center in Houston decades ago — before improved scanning technology was available to evaluate a cancer’s spread.

The new plan is based on 100,000 tumor samples from around the world including Asia, where lung cancer rates are projected to climb because of trends in smoking, unhealthy lifestyles and aging populations. It keeps four broad groupings but sorts people more precisely based on refined understanding of tumor characteristics.

The result: “There will clearly be shifting of patients from categories not operable to operable” — as many as 10,000 a year in the United States, said Dr. David Johnson, a lung cancer specialist at Vanderbilt University in Nashville, Tenn. He reviewed the plan, which was partly published in a medical journal recently.

The stage of the tumor at diagnosis is the best predictor of survival. Only 20 percent of cases are diagnosed in Stages 1 or 2, when tumors are small and confined to a lung, Johnson said. About 30 percent to 40 percent are found in Stage 4, after they have widely spread. The rest are in the middle.

Five-year survival rates are 47 percent for Stage 1 and 26 percent for Stage 2, but only 8 percent for Stage 3, and 2 percent for Stage 4, according to the American College of Surgeons.

Most lung cancers are the type called ”non-small cell,“ which is covered by the new staging system. The system was developed by the International Association for the Study of Lung Cancer, a group of lung cancer specialists from around the world.

Changing groupings

Dr. Peter Goldstraw, a surgeon at the Royal Brompton Hospital in London, led the project, and Canadian scientists independently validated the recommended changes by comparing survival across geographic regions.

Among the changes: creating more sub-stages for tumor size, reassigning some large tumors to a more advanced stage, reclassifying tumors that have spread into the fluid surrounding the lung, and recognizing that spread to certain lymph nodes is more dangerous than its spread to others.

“By changing some of these groupings, some patients will get moved to an earlier stage of disease for which we tend to be more aggressive” in treatment, said Dr. Joan Schiller, a lung cancer specialist at the University of Texas Southwestern Medical Center in Dallas .

“Before, a patient may have only been offered chemotherapy. They may now be offered chemotherapy and radiation,” or more intense radiation, she said. Conversely, some people thought to have earlier-stage tumors now will be grouped with those whose tumors have widely spread, and discouraged from undergoing therapies that have little chance of helping them.

“In some cases, patients were getting inappropriately aggressive treatment,” Schiller said.

Some people with very small tumors may get away with less therapy — taking out just a segment of lung instead of an entire lobe, said Dr. Stephen Swisher, a chest surgeon at M.D. Anderson.

The impact of the changes in Europe and Japan is unclear because doctors in those countries tend to remove whole lungs rather than lobes to treat lung cancer, Johnson noted. Doctors hope that ultimately survival will improve, but that won’t happen “unless we get patients into the right hands” and they get correct treatment, Johnson said.

Revising the staging system also will do little good if doctors don’t do the right tests to properly stage a tumor, said Dr. Len Lichtenfeld, deputy chief medical officer of the American Cancer Society. Staging for lung and other types of cancer should become even more precise in the near future as biomarkers and gene tests are developed to better sort patients, he added.

Risk Factors for Mesothelioma

The main risk factor for developing mesothelioma is exposure to asbestos.

Asbestos refers to a family of fibrous minerals made of silicate. Asbestos was once used in many products such as insulation, floor tiles, door gaskets, soundproofing, roofing, patching compounds, fireproof gloves and ironing board covers, and even brake pads.

As the link between asbestos and mesothelioma has become well known, the use of this material has almost stopped. Most use stopped after 1989, but it is still used in some products. Experts have linked this drop in asbestos use to the fact that the rate of development of mesothelioma is no longer increasing [in the U.S.].

Still, up to 8 million Americans may already have been exposed to asbestos. Exposure to asbestos particles suspended in air and building materials is much less hazardous except when they are being removed.

Since asbestos is a naturally occurring mineral, it can also be found in dust and rocks in certain parts of the United States as well as the world.

According to the U.S. Environmental Protection Agency, as many as 733,000 schools and public buildings in the country today contain asbestos insulation. As many as 10% to 15% of schools in the United States may contain asbestos insulation.

People who may be at risk for occupational asbestos exposure include some miners, factory workers, insulation manufacturers, railroad workers, ship builders, gas mask manufacturers, and construction workers, particularly those involved with installing insulation.

Several studies have shown that family members of people exposed to asbestos at work have an increased risk of developing mesothelioma, because asbestos fibers are carried home on the clothes of the workers.

The incidence rate for mesothelioma in men is dropping, probably because they are no longer being exposed directly to asbestos in their work. But the incidence rate for mesothelioma in women is steady, which suggests that they are being exposed in a way that is not directly tied to work, but more to their environment either at home or work. One example would be asbestos in buildings where they work or live.

A study from California also links mesothelioma to naturally occurring asbestos deposits in mountains.

Another important point about asbestos and mesothelioma is that the risk of mesothelioma does not drop with time after exposure to asbestos. The risk appears to be lifelong and undiminished.

There are 2 main forms of asbestos — serpentine and amphiboles. Serpentine fibers are curly and pliable. Chrysotile is the only type of serpentine fiber and it is the most widely used form of asbestos. Amphiboles are thin, rod-like fibers. There are 5 main types — crocidolite, amosite, anthrophylite, tremolite, and actinolyte. Amphiboles (particularly crocidolite) are considered to be the most carcinogenic (cancer-causing).

However, even the more commonly used chrysotile fibers are associated with malignant (cancerous) mesotheliomas and should be considered dangerous as well.

When asbestos fibers are inhaled, most are cleared in the nose, throat, trachea (windpipe), or bronchi (large breathing tubes of the lungs). Fibers are cleared by sticking to mucus inside the air passages and being coughed up or swallowed. The long, thin, fibers are less readily cleared, and they may reach the ends of the small airways and penetrate into the pleural lining of the lung and chest wall. These fibers may then directly injure mesothelial cells of the pleura, and eventually cause mesothelioma.

Asbestos fibers can also damage cells of the lung and result in asbestosis (formation of scar tissue in the lung), and/or lung cancer.

The risk of lung cancer among people exposed to asbestos is increased by 7 times, compared with the general population. Indeed, asbestosis, mesothelioma, and lung cancer are the 3 most frequent causes of death and disease among people with heavy asbestos exposure.

Peritoneal mesothelioma, which forms in the abdomen, may result from coughing up and swallowing inhaled asbestos fibers. Cancers of the larynx, pancreas, esophagus, colon, and kidney may also come from asbestos exposure, but the increased risk is small.

The risk of developing a mesothelioma is related to how much asbestos a person was exposed to and how long this exposure lasted. People exposed at an early age, for a long period of time, and at higher levels are most likely to develop this cancer.

Mesotheliomas take a long time to develop. The time between first exposure to asbestos and diagnosis of mesothelioma is usually between 20 and 50 years.

Other Asbestos-Related Cancer

Asbestos Related Lung CancerLung cancer, or bronchial carcinoma, occurs in several forms. The most common causes of lung cancer are smoking and asbestos.

This web site has focused on the most lethal of the lung cancers – mesothelioma. Not every asbestos-related lung cancer, however, is a mesothelioma. Other thoracic carcinomas, such as adenocarcinoma, are also caused by exposure to asbestos.

The connection between asbestos exposure and lung cancer was noted as early as 1925, and confirmed over the next 70 years by many epidemiologic studies of asbestos-exposed workers.

The four main types of commercially used asbestos, chrysotile, amosite, anthophyllite, and mixtures containing crocidolite, have all been associated with an increased risk of lung cancer. About one in seven people who suffer from asbestosis, a lung disease resulting from high exposure to asbestos, eventually develop lung cancer.

Asbestos is estimated to account for 3,400 to 8,500 new lung cancer cases in the United States each year. Like mesothelioma, the latency period between asbestos exposure and the development of asbestos related lung cancer may be two, three, four, or even more decades.

Very often, asbestos-related cancer victims also suffer from asbestosis, a scarring of the lung tissue caused by asbestos exposure. About one in seven people with asbestosis will eventually develop lung cancer.

Although commonly associated with lung cancer, adenocarcinoma is a type of cancer that develops in cells lining glandular types of internal organs, such as the lungs, breasts, colon, prostate, stomach, pancreas, and cervix.

Another type of adenocarcinoma, mucinous adenocarcinoma, accounts for only 10-15% of all adenocarcinomas and is particular to aggressive carcinomas that are comprised of at least sixty percent mucus. Non-small cell lung cancers make up over three quarters of all new lung cancer cases in the United States.

While there is only one type of small cell lung cancer, there are three types of non-small cell lung cancer. The three types of non-small cell lung cancer are squamous carcinoma, large cell carcinoma, and adenocarcinoma. When adenocarcinoma develops in the lung’s air sacs, it is called bronchioalveolar adenocarcinoma. About forty percent of all lung cancer cases diagnosed today are adenocarcinoma.

The progression of adenocarcinoma is quite unpredictable. In most cases, adenocarcinoma spreads slowly and causes very few lung cancer symptoms. But it can also be extremely invasive, aggressively spreading through the body and causing death before it can be treated. Given the disease’s variability, the five-year prognosis for patients with adenocarcinoma is dim: most are given only a 10 percent chance of survival.

Sometimes, tumors spread to the liver, adrenal glands, and bones, making adenocarcinoma much more difficult to treat. Symptoms of adenocarcinoma lung cancer may include shortness of breath, the coughing up of blood, fatigue, chest pains, and unexplained weight loss. Adenocarcinoma is usually treated with surgery, radiation therapy, and chemotherapy.

Asbestos is Leading Risk Factor for Mesothelioma

The main risk factor for developing mesothelioma is exposure to asbestos. Asbestos refers to a family of fibrous minerals made of silicate.

Indeed, asbestosis, mesothelioma, and lung cancer are the 3 most frequent causes of death and disease among people with heavy asbestos exposure.

The risk of developing a mesothelioma is related to how much asbestos a person was exposed to and how long this exposure lasted. People exposed at an early age, for a long period of time, and at higher levels are most likely to develop this cancer.

Mesotheliomas take a long time to develop. The time between first exposure to asbestos and diagnosis of mesothelioma is usually between 20 and 50 years.

Asbestosis

asbestosis – Asbestosis is a breathing disorder caused by inhaling asbestos fibers. Prolonged accumulation of these fibers in your lungs can cause scarring of lung tissue and shortness of breath. Asbestosis symptoms can range from mild to severe, and usually don’t appear until years after exposure.

According to information provided by the Mayo Clinic, symptoms of asbestosis include shortness of breath, initially only with exertion but eventually even while resting; decreased tolerance for physical activity; coughing, chest pain, and even finger deformity (clubbing) in some cases.

Asbestosis may cause such a reduced flow of oxygen as to be disabling or even fatal. It can also lead to complications like high blood pressure in the lungs, heart problems, lung cancer, other lung damage including those affecting the lining of the lungs and chest cavity, the pleura. These include pleural thickening and hardening (pleural plaques), and abnormal accumulation of fluid between the layers (pleural effusion).

Asbestosis itself does not increase your risk of developing mesothelioma, but it indicates that you were exposed to asbestos and therefore are also at risk for developing malignant mesothelioma.

Adenocarcinoma

adenocarcinoma (A-den-oh-KAR-sih-NOH-muh) – Cancer that begins in cells that line certain internal organs and that have gland-like (secretory) properties.

Although commonly associated with lung cancer, adenocarcinoma is a type of cancer that develops in cells lining glandular types of internal organs, such as the lungs, breasts, colon, prostate, stomach, pancreas, and cervix. Another type of adenocarcinoma, mucinous adenocarcinoma, accounts for only 10-15% of all adenocarcinomas and is particular to aggressive carcinomas that are comprised of at least sixty percent mucus.

Non-small cell lung cancers make up over three quarters of all new lung cancer cases in the United States. While there is only one type of small cell lung cancer, there are three types of non-small cell lung cancer. The three types of non-small cell lung cancer are squamous carcinoma, large cell carcinoma, and adenocarcinoma. When adenocarcinoma develops in the lung’s air sacs, it is called bronchioalveolar adenocarcinoma. About forty percent of all lung cancer cases diagnosed today is adenocarcinoma.

Like other cancers, adenocarcinoma is the growth of abnormal cells. These cancerous cells multiply out of control and form a tumor. In the lung, as the tumor grows, it destroys parts of the lung. Eventually, the tumor’s abnormal cells can spread (metastasize) to other parts of the body, including the local lymph nodes in the chest and the central portion of the chest, called the mediastinum; the liver; the bones; the adrenal glands; and other organs, including the brain.

Adenocarcinoma is more likely than other types of lung cancer to be contained in one area of the body. If it is truly localized, it may also respond better than other lung cancers to treatment, especially surgical removal of the tumor and draining lymph nodes.

Adenocarcinoma is the most common form of lung cancer. Most of this type of cancer is found in smokers. However, it also is the most frequent type of lung cancer seen in nonsmokers. It is the most common form of lung cancer seen in women and people younger than 45.

As with other forms of lung cancer, you are more likely to get adenocarcinoma if you:

• Are exposed to asbestos. Asbestos is a fibrous mineral that is used in home insulation, fireproofing, tiles for floors and ceilings, automobile brake linings, and other products. It is believed that asbestos fibers can cause lung cancer. People at risk of lung cancer include workers who are exposed to asbestos on the job (miners, construction workers, shipyard workers and auto mechanics who work with brakes), and people who live or work in buildings in which building products that contain asbestos are deteriorating. In addition to the adenocarcinoma type of lung cancer, individuals who have been exposed to asbestos, and particular types of asbestos, are also at a significant greater risk of developing a specialized type of lung cancer called mesothelioma.

• Are exposed to other carcinogens in the workplace. These include uranium, arsenic, vinyl chloride, nickel chromates, coal products, mustard gas, chloromethyl ethers, gasoline, diesel exhaust and high levels of talc dust.

• Smoke cigarettes. Smokers have 13 times more risk of developing lung cancer than nonsmokers. Cigarette smoke is associated with most cases of adenocarcinoma. Smoking is by far the leading risk factor for lung cancer, substantially more significant than all the other risk factors combined.

• Breathe cigarette smoke. Nonsmokers who inhale the cigarette fumes of smokers have an increased risk of lung cancer.

• Are exposed to radon gas. Radon is a colorless, odorless radioactive gas that is formed in the ground. It seeps into the lower floors of homes and public buildings and can contaminate drinking water. Radon exposure is the second leading cause of lung cancer. It’s not clear whether elevated radon levels contribute to lung cancer in nonsmokers. However, research has shown that radon exposure contributes to increased rates of lung cancer in smokers and in people exposed to higher levels of radon, such as miners. You can test the levels of radon in your home and surrounding area by using commercially available radon testing kits.

Your doctor will ask you whether you smoke or whether you live with a smoker. If you smoke, your doctor will ask you how much you smoke and how long you have smoked. Your doctor also will ask whether you have worked in an industry where you may have been exposed to asbestos or other carcinogens.

Call your doctor promptly if you have any of the symptoms of lung cancer, especially if you are a smoker or you have worked in an industry with high exposure to asbestos.

The outlook depends on the stage of the cancer and the overall health of the patient. In general, the prognosis is poor, especially if the lung cancer has spread to areas outside of the chest wall or has involved the lymph nodes of the mediastinum. This cancer can only be cured when surgery or radiation therapy can completely remove the tumor. However, many lung cancers are diagnosed at a stage when this is not possible. About 17 percent of people with adenocarcinoma survive more than 5 years after diagnosis.

Asbestos exposure increases the risk of lung cancer by nine times. A combination of asbestos exposure and cigarette smoking raises the risk to as much as 50 times.

A person who has had lung cancer is more likely to develop a second lung cancer than the average person is to develop a first lung cancer.

Repeated respiratory infections, such as bronchitis or pneumonia, can be a sign of lung cancer.

Asbestos Information

Asbestos and asbestos containing materials are responsible for causing asbestos cancer and asbestos disease cases around the world. Two of the most dangerous forms of asbestos disease are mesothelioma and asbestosis. Asbestos has been used in thousands of products for more than a century because it is highly versatile, abundant, and relatively cheap. Since asbestos is a naturally occurring mineral, it requires no manufacturing. Instead, asbestos only has to be mined, crushed, and added into products during the manufacturing process. Since asbestos is basically a rock, it is highly impervious to heat. It also happens to be chemically inert. Since its basic mineral structure is shaped in long, thin fibers, it can be broken down into these fibers to add strength and flexibility to nearly any product. A characteristic of asbestos is what is known as tensile strength. It allows products to be flexible yet strong while not adding excessive weight. Asbestos is one of few minerals that can actually be woven. Asbestos was commonly woven into materials that made excellent insulators, but were too brittle to be used by alone because they would crumble. Asbestos made insulation products flexible and durable since it was not affected by heat. Asbestos is not a very effective insulator by itself. All these qualities add up to a very useful and inexpensive product but some of them also make asbestos toxic to those that inhale asbestos fibers. There are six forms of asbestos characterized by differences in structure and color. Asbestos is also divided into two categories: serpentine and amphibole asbestos. Serpentine asbestos is made of curly fibers and amphibole asbestos is made of long, straight fibers. Both types of asbestos are considered dangerous, though it is thought amphibole asbestos forms, including crocidolite and amosite, may be more dangerous to humans.

Asbestos Exposure

Unfortunately, there are many opportunities for asbestos exposure since asbestos was used so abundantly in both industrial and consumer products. Most people that develop asbestos cancer and other asbestos diseases, including mesothelioma and asbestosis, usually have a history of chronic exposure to asbestos. Mesothelioma is somewhat unique in this respect, as mesothelioma cases have developed in people with limited asbestos exposure. As a result, there is no established “safe” level of asbestos exposure. Workers are exposed to asbestos when the substance or products containing asbestos are cut, crushed, sanded, drilled or otherwise disturbed. When left undisturbed, asbestos-containing materials can be relatively safe. In cases where asbestos materials are mined, installed, removed, demolished, or serviced, exposure can be a risk unless strict asbestos abatement techniques are employed. When inhaled, microscopic asbestos fibers can make it past the body’s natural defenses and deep into the lungs causing asbestos disease. Once within the lungs, the fibers can irritate lung tissue leading to asbestos cancer. If asbestos fibers make their way to the alveoli or air sacs in the lungs where oxygen and carbon dioxide exchange takes place, they can cause irritation and scarring called asbestosis. Asbestos fibers that pass through the alveoli and into the pleural mesothelium, can eventually lead to asbestos cancer in the form of tumors and malignant mesothelioma.

Asbestos History

Asbestos was first discovered to be dangerous at the beginning of last century. It has been known as a carcinogen since the 1960s and was subsequently banned in more than 30 countries under grounds that there is no safe level of asbestos exposure. Mining and manufacture of most asbestos products has been ceased in the U.S., yet we continue to import more than 30 million pounds of asbestos in foreign products each year. A new recommendation by an EPA-sponsored panel of asbestos industry members and other experts on the topic called for a ban of all importation, manufacture, and mining of asbestos and asbestos containing products in the U.S. Although this may be a good sign, it also means that new risks of asbestos exposure are still developing. Since asbestos cancer and asbestos diseases take years and even decades to develop, many more cases of asbestos disease will be diagnosed.

Asbestos Legislation

On March 1, 2007, Senator Patty Murray (D-WA) introduced S. 742: Ban Asbestos in America Act of 2007 to the 110th Congress. This is an act to amend the Toxic Substances Control Act to reduce the health risks posed by asbestos-containing materials and products having asbestos-containing material, and for other purposes. The bill is an effort to ban all production and use of asbestos in America , launch public education campaigns to raise awareness about its dangers and expand research and treatment of diseases cause by asbestos. Murray’s legislation, which was first introduced in the 107th Congress, will also authorize additional studies to determine which commercial products today still contain asbestos, increase funding for asbestos-related diseases, and call for a national mesothelioma registry to help public health professionals track this deadly asbestos-related disease. Studies estimate that during the next decade, 100,000 victims in the United States will die of an asbestos related disease – equaling 30 deaths per day. The bill passed in the Senate on Oct. 4, 2007 by Unanimous Consent.

Currently, the companion to this bill, H.R. 3339, the Bruce Vento Ban Asbestos and Prevent Mesothelioma Act of 2007, is in committee in the House of Representatives. The House bill toughened the legislation, under the direction of the Environment and Hazardous Material Subcommittee of the House’s Energy and Commerce Committee, eliminating an exception for asbestos present at 1 percent or less by weight, making the ban a matter of federal statute rather than EPA regulation, and adding enforcement provisions. The bill must pass committee to make it before the full House for a vote.

Critically needed medical research funding provisions from Sen. Murray’s and Congresswoman McCollum’s legislation have not yet been added to the Committee Print. Supporters are urged to contact their Representative in Washington, DC, to urge inclusion of the research funding and swift passage of the complete bill once the funding is in place.
