Brief Summary:
Incidence rates of renal cell cancer have increased rapidly in the US and other countries In particular rates among African Americans have risen more sharply than any other cancer site We propose to conduct a population-based case-control study of renal cell cancer in areas of the US with a high proportion of African American residents We will include two study centers and one data coordinating center and will recruit study participants over a period of four years We plan to conduct in-person interviews with 2100 cases 1400 whites and 700 blacks and 2800 controls 1400 each of whites and blacks to elicit information on demographic background and history of exposures A 40 ml blood sample will be collected from living cases and controls to measure certain environmental exposures and for genetic analyses Two buccal cell samples will be collected from living cases and controls for genetic analyses Tumor tissue blocks will be collected from as many cases as possible for assays of tumor mutations Diagnostic slides will be collected for standardized reclassification of tumors into clear cell papillary and other histologic subtypes Medical records for all cases will be reviewed for health insurance coverage concomitant conditions presenting symptoms tumor stage size and grade and methods leading to diagnosis of renal cell cancer
Detailed Description:
Incidence rates of renal cell cancer have increased rapidly in the US and other countries In particular rates among African Americans have risen more sharply than any other cancer site We propose to conduct a population-based case-control study of renal cell cancer two areas of the US with a high proportion of African American residents Detroit Michigan Wayne State University and Chicago Illinois University of Illinois at Chicago Westat Inc is the coordinating center Participants are being recruited over a period of four years A total of 2100 cases 1400 Caucasian Americans and 700 African Americans and 2800 controls 1400 each of Caucasian and African Americans will be recruited In-person interviews are conducted with cases and controls to elicit information on demographic background and history of exposures A 40 ml blood sample and a buccal cell sample are collected from cases and controls for genetic analyses Tumor tissue blocks will be collected from as many cases as possible for assays of tumor mutations Diagnostic slides will be collected for standardized reclassification of tumors into clear cell papillary and other histologic subtypes Medical records for all cases will be reviewed for presenting symptoms tumor stage size and grade and methods leading to diagnosis of renal cell cancer Telephone interviews are conducted with the nest-of-kin of eligible cases who died before we could interview them Permission is being sought from the next-of-kin to assess the cases medical records and obtain tumor tissue samples
