Abstract

Introduction and the aim of the study: Between 1990 and 2005, the number of incidence cases of the malignant neoplasm of the alimentary tract in Podkarpacie region rose from 727 to 1154 and it led to a 63% increase. The aim of the study was to analyse incidence rates for rectal neoplasm within the Podkarpacie area between 1990 and 2005, to make conclusions and confront them with the corresponding data for Poland and other European countries.

Research material and methods: Incidence cases for rectum carcinoma were assessed by the retrospective analysis of material covering 2573 reports. The standardized and crude incidence ratios were formulated and incidence percentage rates were determined, as well. Results: The registered rectum carcinoma in the period under study totaled 2753 incidence cases, out of which 1464 in men and 1109 in women. In 1990, the number of rectal cancer incidence cases for men was 29,5% of all rectal cancers, and for women was 70,5%. The proportion of rectal cancer incidence cases for men and women was 0,66. In 1990, rectal cancers constituted 0,83% of all carcinomas in men and 1,5% in women in Podkarpacie region. In 2005, morbidity in men was 60,5% of all rectal cancers and 39,5% in women. The proportion of rectal cancer incidence cases for men and women was 1,53.

Conclusions: Between 1990 and 2005, rectum cancer morbidity generally increased fivefold which led to the rise of all neoplasms sixfold in men and threefold in women. The neoplasm of the rectum constituted 66,9% in men and 33,1% in women. The crude incidence ratio increased eightfold in men and 3.5-fold in women. The standardized incidence ratio rose more than six times in men and about two times in women.
