title: Mortality trends of malignant tumours of digestive organs in Belgrade, Yugoslavia, 1975-1997.
abstract: OBJECTIVE
  To analyse mortality trends of malignant digestive tract tumours.
  
  
  METHODS
  Population of Belgrade (Yugoslavia) in the period 1975-1997. Mortality rates were standardized by direct method using world population as the standard. For time series, exponential trends were calculated by the use of three-year moving average rates.
  
  
  RESULTS
  In males, the highest mortality rate was for stomach cancer: 14. 6 per 100,000 (average for the period 1975-1997), followed by cancer of liver and cancer of colon: 8.4/100,000, cancer of rectum: 8.1/100,000, cancer of pancreas: 7.3/100,000, oesophageal cancer: 2.8/100,000 and gallbladder cancer: 2.0/100,000. In males, upward mortality trends for carcinomas of colon, rectum, pancreas, oesophagus, gallbladder and bile ducts were observed. The mortality rates series for stomach cancer and liver cancer did not fit any usual trend function. In females, the highest mortality rate was also for stomach cancer 7.7 per 100,000, then for cancer of colon: 6.0/100,000, cancer of rectum: 5.3/100,000, cancer of liver: 4.4/100,000, cancer of pancreas: 4.4/100,000, gallbladder cancer 3.4/100,000 and oesophageal cancer: 0.8/100,000. In females, upward mortality trends were observed for colon and rectal cancer, cancer of pancreas, and gallbladder and bile duct cancer. Downward mortality trends were present for stomach cancer and liver cancer. Mortality rates series for oesophageal cancer did not fit any usual trend function.
  
  
  CONCLUSIONS
  In the majority of digestive tracts cancers, an upward mortality trend was observed which is in keeping with the mortality trends of these malignant tumours in many other countries.
