[Local therapy of rectum carcinoma. A prospective follow-up study]

Abstract

Local therapy of rectal carcinoma with the method of TEM was performed in 98 patients during the period from August 1, 1989 to January 31, 1994. 56 of the patients had pT1, 27 pT2, and 15 pT3 tumours. There was no lethality. The rate of complications, which required operative intervention, was 8%. No lymph node metastases were found in the specimens of the patients with pT1 tumours, who were re-resected, because the margin of the primary specimen were judged to be not free of tumour. In the specimens of the re-resected patients with pT2 carcinomas, lymph node involvement was more common than remnants of the primary tumour. Two of the patients with local therapy of pT1 low-risk carcinomas developed a recurrence so far. A secondary procedure for cure according to oncologic criteria could be performed in both cases. In selected cases the local therapy of rectal carcinoma avoids the high morbidity and mortality of the classical operation. Live quality will be improved, especially if an artificial anus can be avoided. In case of a recurrence the chance of a secondary procedure for cure is not to be underestimated.
