The Upper Midwest Health Study: A case-control study of primary intracranial glioma in rural residents

Background

Brain cancer is nearly uniformly fatal but the etiology of this disease remains largely unknown. Incidence and mortality rose significantly from the mid-70s through the 80s and then declined somewhat. However, among the elderly, rates increased most rapidly and did not then decline (SEER Cancer Fact Sheets, Cancer of the Brain and Other Nervous System 2007.)

Farm workers and Heavy Machinery

Farmers are generally at lower risk for cancer overall. However, farmers have consistently been found to be at increased risk for brain cancer; the reason for the observed increase is unclear.

In 1991 the National Institute for Occupational Safety and Health received a Congressional mandate to study occupational health and safety in the agricultural sector. A group in the Division of Surveillance, Hazard Evaluations and Field Studies focused on cancer in farmers and decided to investigate possible explanations for the excess of brain cancer in farmers. Because brain cancer incidence was elevated in the Upper Midwest, and because these states have substantial farm populations, the study concentrated on Iowa, Michigan, Minnesota, and Wisconsin. Collaborators in each state were recruited for field work. A protocol was approved in 1994 and contracts with the collaborators began that year.

Purpose

To evaluate whether farm exposures explain increased risk of brain cancer among farmers.

To ascertain whether evaluated nonfarm occupational exposures are associated with increased risk of brain cancer among participants in our case-control study.

To identify genetic susceptibility factors associated with increased risk of brain cancer in participants in our case-control study.
