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。
Objective: To understand the efficacy of FEP in the treatment of invasive bladder tumors. Methods: Totally 18 cases of T3 infiltrating bladder tumor were treated with FEP. The patients underwent BEP, pelvic CT and / or cystoscopy before and after treatment, and were reviewed every 3 months thereafter. Results: The changes of coagulation and necrosis were all observed in the bladder cancer patients. The echo of the B ultrasound was significantly enhanced. In the 18 patients, 15 cases of intravesical tumor disappeared (CR = 83.3%) and 3 cases of tumor shrinkage more than 2/3 (PR = 16. 7%), 3 cases of extracapsular invasive mass shrinkage of about 1/3. One case was followed up for 2 years without recurrence, 6 cases were followed up for 12 months and 1 case relapsed. Conclusion: FEP can be used as a new treatment for invasive bladder cancer with obvious curative effect in the near future.
