[The groups at risk for a recurrence of rectal cancer after radical operations].

The article discusses a group of patients with rectal carcinoma who underwent radical operations at the Scientific Research Institute of Proctology in 1982-1983. The terms and frequency of rectal carcinoma recurrences are analysed and the factors influencing these indices are studied. The results made it possible to form a group with a risk of a recurrence among patients with carcinoma of the rectum and suggest new schedules of regular medical observation over these patients with consideration for the risk group.
