Survival Experience of Cancer Patients Enumerated in Morbidity Surveys

Abstract
Survival experience of cases enumerated in morbidity surveys of the National Cancer Institute in 3 of the 10 cities surveyed in 1947–48, and in the State of Iowa, 1950, is presented. A primary objective of this study was to collate the survival experience from cancer case registers and survey sources for information bearing on the comparability of case materials collected by these 2 techniques. A comparison with survival rates reported by the Connecticut register showed no evidence of any large systematic differences in survival experience between cases enumerated in morbidity surveys and those reported to cancer registers. The survey yielded, as a by-product, comparisons of survival experience according to income class in the 3 cities and according to urban-rural residence in Iowa. No important differences in survival were uncovered for these characteristics, even for those sites with income or urban-rural differences in incidence.
