【摘要】 目的 :了解体外聚焦超声热疗 ( FEP)治疗浸润性膀胱肿瘤的疗效。方法 :本文共对 18例 T3期浸润性膀胱肿瘤进行 FEP治疗 ,分别于治疗前、后行膀胱 B超、盆腔 CT及 /或膀胱镜检 ,此后每 3个月复查一次。结果 :膀胱肿瘤治疗后均可见凝固性坏死改变 ,B超回声明显增强 ,18例患者出院时 15例膀胱内肿瘤消失 ( CR=83.3% ) ,3例肿瘤萎缩大于 2 /3 ( PR=16 .7% ) ,3例膀胱外浸润性包块萎缩约 1/3。 1例随访 2年 ,无复发 ,6例患者随访 12个月 ,1例复发。结论 :FEP可作为浸润性膀胱肿瘤的一种新的治疗方法 ,近期疗效显著。更多还原

【Abstract】 Objective:To evaluate the effect of focused extracorporeal pyrotherapy(FEP)for treating infiltrative bladder tumors.Methods:Eighteen patients with infiltrative bladder tumors were treated by FEP and followed up every 3 months.Results:Coagulative necrosis was observed in all patients immediately after treatment.Fiftern tumors(15/18,82 3%)were completely disappeared after treatment and 3 tumors(3/18,16 7%)were partially receded.Three infiltrated masses out of bladder were minimized about one third.One case was followed up for 24 months,and no relapse found.Six patients were followed up for 12 months,and only one patient relapsed.Conclusions:The recent effect of FEP for treating infiltrative bladder tumors is remarkable,FEP may be a new effective and radical method for infiltrative bladder tumors.更多还原
