[Bile duct carcinoma after abdominal irradiation for urologic malignancies]

Malignancies of the biliary tract are rare diseases. Tumor inductions after radiotherapy are reported in several papers. We report about 3 cases with consecutive biliary tract carcinoma 18-32 years after manifestation of an urogenital carcinoma. All 3 patients (52-63 years) were treated with additive radiotherapy after surgical-urological therapy. Icterus was the top-ranging symptom of this secondary carcinoma. In 2 of the 3 cases surgical tumor resection was performed (biliary duct resection with central liver resection; pancreatico-duodenectomy). Because of the bad general condition of health the third patient got only a biopsy of the tumor. All patients died within 2 years after diagnosis. The accidental accumulation of the rare biliary tract carcinoma after urogenital malignancies in our collection of clinical cases (2 seminoma; 1 bladder tumor) give rise the question about the causal association between primary carcinoma, additive therapy and the development of secondary carcinoma.
