Abstract

Rectal cancer is a malignant tumor of the distal colon of epithelial origin. Every year, more than 30 000 (30 969 in 2018) new cases of rectal cancer and 16 000 deaths (16  151) are registered in Russia. The index of reliability of accounting (the ratio of the number of dead to sick individuals) is 0.52%. Rectal cancer refers to localities with an average mortality rate. In the Northwestern Federal District, more than 3000 primary cases of rectal cancer were registered (3285 in 2018). The state statistics on rectal cancer provides data on morbidity and mortality in three categories of ICD-10 together (C19–21). The detailed development of data separately for each category of ICD-10 and for the fourth sign is possible only based on databases of cancer registers. As of January 1, 2019, the population cancer register of the Northwestern Federal District created by us totaled more than 1 million cases of malignant tumors (1 067 661), including rectal cancer (50 745 cases, or 4.8%). The share of rectal cancer is close to the national average, 4.9%. The article presents a detailed structure of cancer pathology in rectal cancer. The leading role of the three specified categories belongs to rectal malignant tumors (C20) (75.4%), 19.8% are malignant tumors of the rectosigmoid department (C19), and only 4.7% are C21, malignant tumors of the anus and anal canal. The dynamics of the structure is presented for all of these categories. It proved to be quite stable.
