ABSTRACT

There were 848 cases of malignant tumors of the gastrointestinal tract admitted to this hospital in the period from April 1955 to December 1964, and 1785 cases from January 1975 to December 1984. A significant elevation of the incidence of the malignant tumors of the gastrointestinal tract was observed in the second 10 years as compared with the number of the total hospital admission in the same period. Esophageal cancer took the leading inthe first 10-year period, then gastric cancer and hepatic cancer followed; while in the second 10-year period, hepatic cancer occupied the first position and was followed by gastric cancer and rectal cancer. The sex ratio was 7.34 :5.82 with a male predo-minauce especially in patients with primary hepatic and esophageal cancers. The age of the patients ranged between 40 and 60 with an average of 46.6 years in the first period and 50.02 in the second. It was interesting to mention that the patients with gastric and rectal cancers were mostly with group A blood.
