title: Epidemiology of gastroenterologic cancer in Henan Province, China.
abstract: OBJECTIVE
  To estimate the mortality rates of gastroenterologic cancers for the period between 1974 and 1999, in Henan Province, China and its epidemiologic features.
  
  
  METHODS
  Information on death of patients with cancer was provided by the county-city registries. Population data were provided by the local police bureau. All the deaths of cancer registered were classified according to the three-digit rubric of the ICD-9. Cancer mortality rates reported herein were age-adjusted, using the world population as standard and weighted piecewise linear regression analysis.
  
  
  RESULTS
  Total cancer age-adjusted mortality rates were 195.91 per 100,000 for males and 124.36 per 100,000 for females between 1996 and 1998. During the period of 1974-1999, a remarkable decrease took place in esophageal carcinoma, stomach cancer remained essentially stable and liver cancer, a moderate increase. Colorectal cancer was slightly increased over the last two decades.
  
  
  CONCLUSIONS
  The population-based cancer registry can give an accurate picture of cancer in Henan Province, by providing a set of analyses of selected cancer mortality data as a source of reference for researchers in cancer, public health and health care services.
