The findings showed that P36 located mainly in the cytoplasm with a small amount in cellular membrane and its total positive rate was 53. 3%. In patients whose tumor cells were deeply infiltrated and poorly differentiated, and who relapsed and died, the positive staining was stronger. The result indicates that P36 is an important molecule closely related to trans formation of bladder cancer. It is an essential marker for judging the malignancy and prognosis of bladder cancer.展开更多
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（transurethral resection of bladder tumor，TURBt）术后加用髂内动脉栓塞化疗。...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（transurethral resection of bladder tumor，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。展开更多
