[Malignant tumors in patients in our hospital 1985-1989]

An analysis was conducted concerning the data on malignant digestive-tract tumors which were treated in the period from 1985 to 1989 at the Department for Gastroenterology of the Clinical-Hospital Center in Zemun. The research results showed that malignant digestive-tract tumors are not in an increase, they are rare in persons which are younger than 40 years of age (10%) and are two times more frequent in males. The share of malignant tumors of the large intestine in overall morbidity is somewhat more frequent, they occur two times more in males and with 10.6% in persons younger than 40 years. The malignant tumors of the stomach are the only ones which are in a decrease, they are considerably less frequent in younger persons (3.7%), but are also two times more frequent in males. Malignant tumors of the pancreas are somewhat more represented in overall morbidity, they are very rare in young persons (3.7%) and are more frequent in males. The data on malignant tumors of the liver show that in the last few years they are somewhat more represented in overall morbidity, they are rare in persons younger than 40, and are more frequent in males.
