Minnesota researchers ‘making progress’ in mesothelioma study

Researchers studying an unusually high incidence of mesothelioma among Iron Range miners and their families reported they are “making progress” as five-year program gets underway, according to the Star Tribune, which serves Minneapolis and St. Paul. The $4.9 million research program was funded by the Minnesota state legislature in April.

The program is being directed by the University of Minnesota. Researchers held an open meeting yesterday evening to share initial results. The program, which involves health screenings for residents of the Iron Range, particularly mine workers and their families, began in Summer 2007, but got a boost when the legislature approved the funding to expand the study significantly. The funding established the Minnesota Taconite Workers Lung Health Partnership task force.

The Star Tribune reports that the program will expand in 2009 to include a respiratory health assessment of 1,200 active and retired miners, as well as 800 spouses or partners. Participants will be selected at random. Physical testing will be handled by the Virginia Regional Medical Center, and testing is exected to run for a period of about 6-9 months.

While mesothelioma is almost exclusively associated with asbestos, researchers are investigating whether or not there is a link between taconite dust – which is produced in the Iron Range mining process – and mesothelioma. To date 58 mesothelioma deaths have been linked to the Iron Range.

According to the Star Tribune report, there are four ongoing health studies associated with this project: a mortality study under the direction of the related to miner deaths; a cancer rate incidence study; a respiratory health assessment for miners or former miners; and an occupational exposure study. In addition, the paper reports two environmental studies are part of the process as well, under the direction of the Natural Resources and Research Institute the University of Minnesota Duluth. These will examine sediments in lake bottoms as well as airborne particle measurements.


Mesothelioma claims 59th Iron Range miner

The Minnesota Department of Health reported this week that a 59th case of mesothelioma was identified in an Iron Range mine worker. This is the latest bad news in an ongoing examination of unusually high rates of mesothelioma among the miners. The state government recently approved $4.9 million to study the situation.

According to the Duluth News Tribune, the news of the latest mesothelioma diagnosis was discovered as the result of a comparison study done by the , comparing 72,000 Iron Range miners against the Minnesota Cancer Surveillance System, which is the state’s cancer registry. The paper reports Health Department spokesperson Buddy Ferguson was unable to provide details about the 59th miner diagnosed, including whether or not this case of mesothelioma had resulted in an additional death.

A focus of the five-year study, which is under the direction of the University of Minnesota’s School of Public Health, is to determine if there is a relationship between mesothelioma and the dust from taconite mining that is a central part of the Iron Range mine operation. Currently, mesothelioma is known only to be linked to asbestos. Because of the long latency period of the disease, usually between 20 and 50 years, it is uncertain whether the mesothelioma cases could be caused by previous asbestos exposure on the part of affected individuals, or taconite dust, or both.

Minnesota Public Radio reported in June 2007 that the Department of Health had conducted a study in 2003 when it found 17 cases of mesothelioma among Iron Range workers, and determined that 14 of the 17 cases had previous exposure to asbestos as well as taconite dust. Between 2003 and 2007, an additional 35 miners were diagnosed with mesothelioma.

According to WDIO-DT and WIRT-DT, ABC affiliates channels 10 and 13 serving the Northland area, approximately 1,200 current and former Iron Range miners will undergo random respiratory and health screenings, beginning next summer, as part of the study. The station reports that this summer researchers will begin analyzing old health studies, and doctors will examine current asbestos exposure controls.

The research study group has been named the Taconite Workers Lung Health Partnership. Read more about the project at its web site.
