【摘要】 目的探讨经尿道膀胱肿瘤电切术后单次髂内动脉栓塞化疗对难治性膀胱癌的疗效。方法1999年11月~2005年6月,对12例难治性膀胱癌应用经尿道膀胱肿瘤电切(transurethralresectionofbladdertumor,TURBt)术后加用髂内动脉栓塞化疗。先经尿道将膀胱肿瘤完整切除,术后1周行双侧髂内动脉造影,采用Seldinger技术,经右侧股动脉插管,明确正常血供与肿瘤血管,然后向双侧髂内动脉各注入半量化疗药物(表阿霉素各25mg),再超选择至膀胱肿瘤血管注入末梢栓塞剂(即化疗栓塞剂,为明胶海绵碎块与顺铂200mg之混合物),可反复栓塞,直至所有肿瘤血管化疗栓塞满意为止。术后常规用表阿霉素膀胱灌注,每3个月复查膀胱镜。结果动脉栓塞化疗后,12例均有恶心、食欲不振,呕吐3例,发热2例,经对症处理缓解。臀部轻度疼痛6例,3~5日缓解。血红细胞、白细胞减少4例,对症处理2周后正常。肝肾功能无明显变化。随访4~55个月,平均34个月。1例术后12个月复发,其余11例无瘤生存。结论此种方法治疗难治性膀胱癌的复发率低、副作用小,为不愿行膀胱全切的患者提供了一种新的选择。更多还原

【Abstract】 Objective To evaluate clinical effects of single-dose intra-arterial infusion chemotherapy for the treatment of refractory bladder cancer after transurethral resection of bladder tumor (TURBt). Methods A retrospective analysis was made on clinical data of 12 cases of refractory bladder cancer treated by single-dose intra-arterial infusion chemotherapy after TURBt from November 1999 to June 2005. The bladder tumor was resected as thoroughly as possible. Postoperatively, a bilateral internal iliac arteriography was made by using the Seldinger technique. The tumor vessels and normal blood supply were identified through the intubation of the right femoral artery. Half dose of chemotherapeutics (epirubicin 25 mg) was infused into both internal iliac artery, then tumor vessels of bladder was selected and infused with peripheral embolization agent (a mix of fragmented gelatin sponge and cisplatin 200 mg). The embolization agent was used repeatedly until all tumor vessels were embolized. Intravesical instillation with epirubicin was carried out postoperatively, and cystoscopy was performed every 3 months after operation. Results After intra-arterial infusion chemotherapy, there were 12 cases of nausea and anepithymia, 3 cases of vomiting, and 2 cases of fever, all of which were symptomatically relieved with expectant treatment. Mild hip pain occurred in 6 cases and subsided in 3~5 days. Decreased erythrocyte and leucocyte were restored to normal levels in 2 weeks. Liver and renal functions did not present marked changes. Follow-up was conducted for 4~55 months (mean, 34 months). There were 1 case of recurrence at 32 postoperative month and 11 cases of progression free survival. Conclusions This technique lowers the recurrent rate of refractory bladder cancer and the incidence of side effects, being a new alternative for patients who are not willing to receive total cystectomy.更多还原
