Abstract:
Objective To study the efficacy,late complications and prognostic factors of postopera-tive radiotherapy for bladder cancer: Methods Between July 1995 and January 21307,109 patients with primary bladder cancer who had received adjuvant pelvic radiation therapy were retrospectively analyzed. The age ranged from 41 to 94 (median 68) years. There were 29 patients with T1 disease,60 with T2,17 with T3, 3 with T4, and 7 with positive lymph node. Three-dimensional radiotherapy was given with a median total dose of 49.2 Gy(39.3 -62.2 Gy) in conventional fractionation after surgery. Field-in-field intensity modu-lated radiotherapy was given to 57 patients. Results The total follow-up rate was 98% ,with a median fol-low up time of 36(2-144) months. The 1-,3- and 5-year local control rate was 63% ,47% and 42% ,respec-tively. The 1-,3- and 5-year overall survival rate was 80% ,48% and 37% ,respectively. Among the 109 pa-tients,33 died of tumor progression or metastasis,42 showed local recurrence,and 22 had lymph node metas-tasis. According to the RTOG criteria,grade 1,2,3 and 4 radiation related early urological side effects were 22% ,59% ,12% and 1% ,respectively;The corresponding late urological side effects were 29% ,28% ,2% and 1%, respectively. Two patients underwent whole bladder cystectomy due to the radiation related side effects. Conclusions Postoperative three-dimensional radiotherapy, achieving high response rate with tol-erable side effects, can be offered as an alternative option to the radical cystectomy in the bladder conserving treatment.
