脐尿管癌是来源于脐尿管上皮罕见的恶性肿瘤,由于发生部位特殊,早期诊治比较困难。本研究探讨脐尿管癌的临床特点、诊断、治疗方式及预后因素。结论 :脐尿管癌发病位隐匿,术前诊断较为困难,治疗采取扩大性膀胱部分切除术或根治性全膀胱切除,辅以全身化疗、放疗为主的综合治疗可能有助于延长患者生存期。本病的预后很差,临床分期与预后密切相关。
Urethral cancer is a rare malignant tumor derived from the epithelium of the urachus. Because of its special site, early diagnosis and treatment are difficult. This study was to investigate the clinical features, diagnosis, treatment and prognostic factors of urachal carcinoma. Conclusions: The location of urachal carcinoma is obscure and it is difficult to diagnose it preoperatively. The treatment with enlarged partial or partial radical cystectomy combined with systemic chemotherapy and radiotherapy may help to prolong the survival of patients . The prognosis of this disease is poor, the clinical stage and prognosis are closely related.
