title: [Indications for radiotherapy of rectal cancer].
abstract: Surgery and radiotherapy complete each other in local control of suffering from rectal carcinoma. A radiotherapeutic effect on tumor is secured often. The adjuvant radiotherapy is the most interesting indication, though the most controversial as present too. Analysing all data and with experiences of an own irradiation study we have not any doubt that the indication is qualified for a combined therapy, if the therapeutic aim with priority is to prevent a local relapse as the most frequent and complained of form of therapeutic failure. In this problem, radical irradiation forms, as pre- and accumulating irradiation (sandwich-technique) and after-irradiation, render superior to an exclusive pre irradiation. In result of this study we practise a preirradiation of 25 Gy with immediately following operation and an accumulating irradiation to 50 Gy in proved high-risk-stage (T greater than or equal to 3 NoMo,Tx N1-3 Mo). If there is a primary local incurability by tumor invasion into the neighbourhood a pre-irradiation is done with 50 Gy and following explorative laparatomy within 4-6 weeks. Nearly 60% of these tumors become operable after that. Likewise we practise in unirradiated patients with locoregional tumor recurrence. Also here the extirpation quota of patients with general or systemic incurability, that a stoma construction is required in, we carry out a transanal tumor reduction and irradiate with 50 Gy after that. Especially this therapeutic principle has proved its worth in patients that are past eighty. Here with acceptable living quality and avoiding a stoma construction a survival can be reached that corresponds to the statistical survival of this stage of life.
