Organ preservation treatment of bladder cancer-a new model by trimodality (107 cases report) / 中华泌尿外科杂志

ABSTRACT

Objective To detect the efficacy of trimodality treatment combining transurethral resection of bladder tumor (TURBT), chemotherapy and radiotherapy for locally muscle-invasive bladder cancer.Methods From November 2007 to June 2013, 107 local muscle-invasive bladder cancer cases were treated by TURBT.Thirty-six cases ( group A) underwent the bladder-sparing trimodality treatment, aged from 42 to 88 years.Seventy -one cases (group B) underwent radical cystectomy,aged from 38 to 77 years.In group A, there were 19 cases of T2 , 13 cases of T3 , and 4 cases of T4a.Among those patients, 11 patients underwent gemcitabine/cisplatin ( GC ) systemic chemotherapy regimen, 15 patients underwent gemcitabine/cisplatin ( GC ) intrailliac artery chemotherapy regimen, and 10 patients underwent taxane/carboplatin ( TC) systemic chemotherapy regimen.In group B, there were 38 cases of T2 , 27 cases of T3 , 6 cases of T4a.The progress-free survival after 2 years was compared with the only radical cystectomy, and the efficacy among the three chemotherapy regimens was also evaluated.Results There is no statistical difference in age and tumor stage between the two groups.In group A, patients were followed up from 3 to 79 months, and 2 years′progress-free survival was 78.9%(15 cases) in T2 , 46.2%(6 cases) in T3 , and 0 in T4a.In group A, organ-sparing 2 years′progress-free survival was 58.3%, and 6 metastasis (16.7%) and 11 local relapse ( 30.6%) were detected during the follow-up period.In group B, patients were followed up from 2 to 65 months, and 2 years′progress-free survival was 76.3%in T2(29 cases), 55.6%(15 cases) in T3, and 16.7% (1 case) in T4a.Of all the patients in group B, 2 years′progress-free survival was 63.4%, and 22 metastasis ( 31.0%) and 16 local relapse ( 22.5%) were found during the follow-up period.There′s no statistical difference on 2 years′progress-free survival between the two groups, and the efficacy among the three chemotherapy regimens.Conclusions Two years′progress-free survival of bladder-preserving trimodality treatment was similar to that of radical cystectomy for local muscle-invasive bladder cancer.In term of treatment efficacy, stage T2 was much better than T3 and T4a .Each kind of chemotherapy regimen in trimodality treatment was equally effective.
