GASTROINTESTINAL CANCER STATISTICS

Abstract

The purpose of the study was to analyze the incidence and mortality rates of gastrointestinal cancer, and to provide data on the current state of cancer care for these patients. Material and methods. The crude and age-standardized incidence and mortality rates, median age of patients and increase in absolute number of cases were calculated. Mathematical and statistical methods were used. Results. The number of patients with gastrointestinal cancer continues to grow in Russia. Morphological verification of the diagnosis was 90–95 % for stomach, colon, rectum and esophagus cancers. A low incidence rate was observed for liver cancer (58.1 %) and pancreatic cancer (55 %). From 2010 to 2015, the incidence of stomach cancer decreased by 15.1 % in men and by 12.5 % in women; the incidence of colorectal cancer increased by 2.8 in men and by 4.5 % in women. The cancer mortality rates decreased for most cancers, except for liver cancer and pancreatic cancer (in men). The mortality rates for colorectal cancer and liver cancer in women were stable (7.5 per 100,000 and 2.4 per 100,000, respectively). A comparative analysis of the incidence and mortality rates in the countries of the former USSR, as well as in various regions of Russia was carried out.
