title: Trends in cancer incidence in esophagus, stomach, colon, rectum and liver in males in India.
abstract: Time trends in cancers of the esophagus, stomach, colon, rectum and liver cancers among the male population in five Indian urban population based cancer registries (Mumbai, Bangalore, Chennai, Delhi, and Bhopal) were examined over the period of the last two decades. The model applied fits data to the logarithm of Y=ABx. This Linear Regression method showed decreasing trends in age-adjusted incidence rates for cancers of the stomach and esophagus, especially in Bjopal, and increasing trends for colon and rectum and liver, throughout the entire period of observation in most of the registries. The five cancers together constitute more than 80% of the total gastro intestinal cancers and are serious diseases in both sexes. To understand the etiology of these cancers in depth, analytic epidemiological studies should be planned in the near future on a priority basis.
