Objective: to study the results of sparing cystectomy in patients with urinary bladder cancer (UBC).Subjects and methods. The study has covered 82 patients with transitional-cell UBC (T1-4aN0M0) who received radiotherapy (RT) and thenunderwent radical cystectomy at the N.N. Blokhin Russian Cancer Research Center, Russian Academy of Medical Sciences, in 1980 to2007. Among them there were 76 (92.7%) males and 6 (7.3%) females. The median age was 55.2±10.8 years. Superficial (T1) and inva-sive (Т2—4а) carcinomas were detected in 33 (40.2%) and 49 (59.8%) patients, respectively. Category N+ was identified in 3 (3.7%) patients.All the patients received RT to the bladder area (median total focal dose (TFD) 56±12.3 Gy) and regional metastatic zones (median TFD40.0±0.0 Gy). A full effect of irradiation was achieved in 44 (53.7%) patients, of whom 41 (93.2%) developed local relapses. All the 82patients underwent radical cystectomy: that with ureterostomy in 28 (34.1%) cases, Bricker’s operation in 45 (54.4%), Studer’s operationin 4 (4.9%), and rectal urinary bladder in 5 (6.1%). The median follow-up was 32.7±31.9 months.Results. The median interval between RT and cystectomy was 12.5±5.1 months; the median time of surgery was 360 (60—480) min; themedian blood loss was 1515.2±1227.8 ml. Intraoperative and postoperative complications developed in 10 (12.2%) and 40 (48.6%)patients, respectively. Repeated operations were performed in 7 (8.4%) cases. Mortality was 4.9%. A urinary derivation technique failed toaffect the incidence of complications and the rates of mortality (p > 0.05). Histological studies revealed transitional-cell carcinoma in thedistant specimens in 80 (97.6%) cases. Recurrences developed in 40 (48.8%) of the 82 patients following an average of 32.9 (1—150)months of cystectomy: local relapses in 5 (6.1%) cases; distant metastases in 29 (35.4%); a local relapse and distant metastases in 5 (6.1%);urethral recurrence in 1 (1.2%) patient. Five-year overall, specific, and relapse-free survivals were 43.9 (median 48.4±10.5 months), 48.5(59.9±9.3 months), and 42.8% (47.4±9.6 months), respectively. Conclusion. Sparing cystectomy with any urinary derivation technique is associated with the acceptable frequency of complications and pro-vides fair long-term results in patients who show no complete effect or who have a local UBC relapse after RT.
