[Early detection and results of therapy of malignant tumours of the rectum and sigmoid colon (author's transl)]. / Früherkennung und Behandlungsergebnisse bösartiger Rektum- und Sigmatumoren.

An analysis of statistical data indicates 0 growth of incidence and high percentage of advanced cases of rectum and colon cancer. The mean duration of preoperative history of rectum cancer comprises 8,9 months. The main causes of late diagnosis included the patients' unawareness of the symptoms of the lesion, and the defects of examinations performed in out-patient clinics. The efficacy of medical services rendered to this group of patients can be improved by extending the system of proctological services, establishing a practice of specialized out-patient examinations, screening procedures by proctologists, as well as developing modern diagnostic and operative measures for oncological lesions.
