The nitrogen balance was studied in cancer of the rectum cases before operation and in various periods after it. For a comparative analysis the nitrogen balance studies were carried out in duodenal and gastric ulcer cases and in 25 practically healthy individuals, who constituted a control group. A persistent negative nitrogen balance was found in cancer of the rectum. The authors developed an effective pathogenic therapy with due regard for revealed changes.
