Current status and controversy of surgical treatment for oligometastatic bladder cancer
-
摘要: 膀胱癌(BCa)是发病率第2位的泌尿男生殖系恶性肿瘤,一旦发生转移,预后极差。目前转移性膀胱癌(mBCa)的标准治疗方案为基于顺铂的联合系统性化疗,但其治疗反应率及生存率较低,大部分患者化疗后仍会出现疾病进展。研究显示,寡转移膀胱癌行减瘤性膀胱全切除术或转移灶切除术可为部分患者提供生存获益。但现有研究较少且均为回顾性研究,寡转移膀胱癌的概念与诊断标准尚未得到统一,仍需要进一步前瞻性随机对照研究探索寡转移膀胱癌诊断标准及外科手术治疗的可行性、有效性及手术时机。Abstract: Bladder cancer(BCa) is the second common urinary and genital carcinoma in males. The prognosis of BCa is poor once metastasis occurs. Currently, the standard treatment for metastatic bladder cancer(mBCa) is systemic combination chemotherapy based on cisplatin. However, the treatment response rate and survival rate are low, and most patients still experience disease progression after chemotherapy. Previous studies indicated that cytoreduced total cystectomy and metastasectomy might provide survival benefits for patients with oligometastatic bladder cancer. However, there are few studies related to oligometastatic bladder cancer currently and all of them are retrospective. Besides, there is no consensus on the concept and diagnostic criteria of oligometastatic bladder cancer. Further prospective randomized controlled studies are needed to explore the diagnostic criteria of oligometastatic bladder cancer and the feasibility, effectiveness and optimal timing of surgical management.
