[Autopsy results in surgical-radiotherapeutic treatment of bladder carcinoma--conclusions for optimal radiologic therapy].

Abstract

With 282 autopsied patients with bladder carcinoma, that were treated by combined operation and radiotherapy, conclusions are given for tendency in tumor spreading as well as for complications and late-effects of radiotherapy. In 24.5% of the cases tumor tissue was found within the bladder and in 30.5% of the cases within the minor pelvis. Metastases were found in 24.1% in iliac lymph-nodes, in 21.3% of the autopsy cases in abdominal lymph-nodes. Liver, lungs, bones, and kidneys are main organs for hematological metastasizing. Little or undifferentiated carcinomas and squamous cell carcinomas show a greater tendency to metastasize than highly and medium-differentiated ureteral carcinomas. The least radiotherapeutical complications and late-effects were found in a fractionation with daily 1.5 Gy and a total dose of 60 Gy (necrotising urocystitis 17.9%, proctitis 3.6%).
