title: Skin cancer epidemiology: research needs.
abstract: The basis data currently being used to estimate and evaluate the dose-response relationship of UV-B and skin cancer are from a 6-month survey for four areas that participated in the TNCS, 1971-1972. Although most investigators from various fields of interest outside of cancer research, i.e. aviation, environmental ecology, physics, chemistry, and photobiology, etc., may admit an association between nonmelanoma skin cancer and UV-B exists, they point out that 1) the epidemiologic data currently available are too sparse and lack certain detail, such as exposure patterns and skin types, and 2) more data of this type are needed over a broad geographical range to allow for more precise measurements of the effects of stratospheric ozone depletion. They argue that the present relationships could change drastically with the addition even of a few more points (geographical locations) and that location-specific and demographic factors should be evaluated. Therefore, these data need to be updated and expanded to include more locations over a longer study period. The National Cancer Institute and the Environmental Protection Agency undertook a special skin cancer study from June 1, 1977 to May 31, 1978. The objectives of this study were: 1) to determine the incidence of nonmelanoma skin cancer (basal cell and squamous cell carcinomas) in various population groups within the United States, and 2) to ascertain and measure epidemiologic factors that may contribute toward the excess risk of nonmelanoma skin cancer in specific population groups.
