| 1 | A phase II study of neoadjuvant chemotherapy followed by organ preservation in patients with muscle-invasive bladder cancer显示文摘Objective:Conservative approaches in muscle-invasive bladder cancer(MIBC)have been evolved to avoid aggressive surgery,but are limited to elderly,frail,and patients medically unfit for surgery.Our study aimed to assess the response rate of neoadjuvant chemotherapy(NACT)before radiotherapy(RT)in MIBC patients.Methods:Forty patients with urothelial carcinoma of stage T2-T4a,N0,M0 were enrolled between November 2013 and November 2015,and treated with three cycles of NACT with gemcitabine-cisplatin.Post-NACT response was assessed using Response Evaluation Criteria in Solid Tumors(RECIST)criteria.Patients who achieved complete response(CR)and partial response(PR)>50%were treated with radical RT,and those who had PR<50%,stable disease(SD),and progressive disease(PD)underwent radical cystectomy(RC).Survival analysis was done with Kaplan-Meier method and point-to-time events were analyzed with Cox-proportional hazards regression model.Results:After NACT,35(87.5%)patients achieved either PR>50%or CR,and were treated with RT.Five(12.5%)patients who had PR<50%,SD,or PD underwent RC.All patients who received radiation showed CR after 6 weeks.Median follow-up was 43 months(range:10-66 months)and median overall survival(OS)was not reached.Three-year OS,local control,and disease-free survival were 70.1%,60.9%,50.6%,respectively,and 50%of patients preserved their functioning bladder.Three-year OS rate was 88.9%in patients who achieved CR to NACT,73.1%in patients with PR≥50%and 40%in patients with PR<50%.Conclusion:NACT followed by RT provides a high probability of local response with bladder preservation in CR patients.Appropriate use of this treatment regimen in carefully selected patients may omit the need for morbid surgery. | Chinna Babu Dracham Narendra Kumar Santosh Kumar Arun Elangovan Budhi Singh Yadav Ravimohan S.Mavuduru Anupam Lal Pramod K.Gupta Rakesh Kapoor | 2022 | Asian Journal of Urology2022，9，3： | 1 |
