IS PARTIAL CYSTECTOMY THE TREATMENT OF CHOICE FOR MUCINOUS ADENOCARCINOMA OF THE URACHUS

Objectives. To determine if well-differentiated colonic-type adenocarc inoma of the urachus behaves benign fashion, and thus might be treated by segmental rather than radical cystectomy. Methods. A retrospective review of the literature since 1863 with one added case review is pre sented here, Only cases with photomicrograph confirmation were accepte d. Results. Sixteen previously reported patients with well-differentia ted colonic-type adenocarcinoma of the urachus were treated by partial cystectomy. None were treated by radical cystectomy. Most (88%) of th ese patients were cured, whereas all patients (100%) treated in the la st 45 years were cured. Conclusions. These data support a more limited approach to the surgical excision of these benign-appearing tumors. T he influence of this histologic type on the prognosis of patients with urachal tumors has not been previously reported. (C) 1997, Elsevier S cience Inc.
