Description:Excerpt from Annual Report of Program Activities, National Cancer Institute, Fiscal Year 1981, Vol. 3: Division of Cancer Cause and Prevention In the past, survival data were compiled on patients diagnosed in 1950-73, based on data from four large cancer registries. This year the series was extended to include follow-up through 1978, permitting an analysis of trends in 5-year survival rates between those first diagnosed in 1970-73 and those in 1960-63. The survival rates increased significantly for most of the major sites of cancer. The seer Program will soon provide follow-up data through 1980, so that 5-year survival rates can be evaluated for a large population-based sample of patients diagnosed in 1973-75. Major differences between whites and blacks have been found in the survival rates of various cancers, and studies are planned to identify the responsible factors. Special emphasis was placed this year on case - control and cohort studies to evaluate key hypotheses in cancer etiology. Occupational studies are a time-tested means of identifying physical and chemical carcinogens, and were pursued to assess hazards suspected on the basis of experimental, clinical, and field observations. Preliminary surveys of petroleum workers revealed excesses of certain cancers, notably of the brain, while professional artists showed increases of leukemia and bladder cancer. Considerable effort was devoted to working with other Government agencies such as the Social Security Administration, to utilize record systems that could help in identifying occupational groups at high risk of cancer.
