Recent trends in cancer incidence in Kiev 1969-1979.

The analysis of the trends of age-adjusted incidence rates of malignant tumors in the city of Kiev in the years 1969-1979 revealed a gradual increase of the majority of individual sites, mainly of the malignant tumors of rectum, lymphoid and hematopoietic tissues in both sexes and of breast in females. On the other hand a decrease of incidence rates of the malignancies of skin, lip and stomach in both sexes and of oesophagus, lung and uterine cervix in females was noted. These investigations formed the basis of the prognosis study of incidence rates of malignant tumors in Kiev until 1990. The importance of the study of incidence rates and trends of individual sites of malignant tumors for the investigation of their factors and causes in urban conditions and environment is emphasized.
