Case-control study of neuroepithelial tumors in Rochester, Minnesota, 1950-1977

Abstract

Rochester, Minnesota, has over many decades the highest reported incidence rates of primary intracranial neoplasms. This occurs in the absence of any readily identifiable risk factors. A case-control study of neuroepithelial tumors has been undertaken utilizing the records-linkage system at the Mayo Clinic. This study failed to yield any significant findings for the factors examined.
