Abstract:
Objective To study the clinicopathologic features and the effects of various surgical methods of urachal carcinoma,to improve the diagnosis and treatment of this disease. Methods The clinicopathologic features,diagnosis, surgical methods and effects of 9 patients diagnosed as urachal carcinoma were analyzed retrospectively. Results Among 9 patients,7 cases were diagnosed as mucinous adenocarcinoma, 1 case as nonclassified adenocarcinoma and 1 case as small cell neuroendocrine carcinoma. According to Sheldon staging system,8 cases were classified into stage Ⅲ A and 1 case into stage Ⅲ C. Eight cased underwent extensive partial cystectomy,whereas the other one underwent regular partial cystectomy. One patient died of multiple bone-metastasis at 3 months after operation, 1 patient received operation again for recurrence at 11 months after operation and 1 patient experienced recurrence in bladder neck and urethra respectively at 15 months and 24 months after operation and receivedTUR-Bt. All of the other 6 patients lived without recurrence and metastasis by follow-up survey of 6 - 42 months. Conclusions Urachal carcinoma is a rare malignant tumor,which has very poor prognosis. Clinicopathologic features recognition is very important for improving the diagnosis of this disease. The long-term disease free survival can be achieved from extensive partial cystectomy.
