This population-based case-control study was conducted from 2000-2003 in two major cities in Poland, Warsaw and Lodz, and enrolled 2,386 breast cancer cases and 2,798 age and site matched controls. The study utilized state-of-the art exposure assessment techniques, including detailed personal interviews, anthropometric measurements, physical activity monitors, and collection of dust samples from the participants’ homes. In order to facilitate study of a wide range of biomarkers, biological specimen collection included blood samples processed as cryopreserved whole blood, serum+ blood clot, plasma+buffy coat+red blood cells; 12-hour overnight urine; paraffin-embedded tumor and normal tissue; and fresh tissue from tumors, non-neoplastic breast tissue, and mammary fat tissue.
Investigators in DCEG obtained ten-year follow-up information from medical records for approximately 1,300 breast cancer cases recruited in Warsaw and 300 cases recruited in Lodz, as well as mortality data on most cases in the study using the Cancer Registry and Death Certificate Office database in Poland. The main research projects being conducted include:
