Abstract:
In the last decade, there has been an increase in the incidence of malignant tumors
of the rectum (RC) in the world. An incidence of 50 new cases of colorectal cancer per
100,000 population per year indicates a 5% population lifetime risk of developing the
diseaseIt is alarming that 100 newly diagnosed malignant neoplasms of the rectum
(MNR) account for more than 70 deaths, 40% of them in the first year after diagnosis.
In 62.4% of patients, late forms of MNR (stages III-IV) were detected at the first
appearance. Surgery alone has shown poor MNR follow-up—five-year survival rates
have been consistently low over the last 20–25 years, averaging 52%.
