What ' s known on the subject? and What does the study add?Radical cystectomy remains associated with comparatively high perioperative morbidity and mortality, despite improvements in surgical techniques and perioperative care. At present, most studies on the complications associated with open radical cystectomy were derived from Western academic high-volume centres, and data from Japan and other Asian countries were very limited.Using the modifi ed Clavien grading system and 11 category grouping reported from MSKCC, we observed that 68% of patients experienced at least one complication within 90 days of surgery, and 17% of patients experienced major complications (90-day mortality rate = 2%), which were compatible with reports from Western high-volume centres. As far as we know, our report is the largest one regarding perioperative morbidity and mortality in Asian patients who underwent radical cystectomy. OBJECTIVE• To determine the type, incidence and severity of 90-day morbidity after radical cystectomy in our institution and our affi liated hospitals in accordance with a standard reporting methodology. A t present, most studies on complications associated with open radical cystectomy are derived from W estern academic high-volume centres and data from J apan and other A sian countries remain very limited. PATIENTS AND METHODS• The study comprised a retrospective multi-institutional study.• The records were reviewed of 928 patients who underwent open radical cystectomy between 1997 and 2010.• All complications within 90 days of surgery were categorized into 11 specifi c categories and graded in accordance with the modifi ed C lavien system.• Multivariate regression models were used to determine predictors of complications. RESULTS• A t least one complication was observed in 635 (68%) patients and a major (grade 3-5) complication was observed in 156 (17%) patients.• The most common complication categories were infectious (30%), gastrointestinal (26%), wound-related (21%) and genitourinary (15%).• The 30-day mortality rate was 0.8% and the 90-day mortality rate was 2%.• A multivariate regression model showed that previous cardiovascular comorbidity and type of urinary diversion (i.e. ileal conduit or neobladder) were signifi cant factors for any and major complications. CONCLUSIONS• Surgical complication-related radical cystectomy is signifi cant and both previous cardiovascular comorbidity and the type of urinary diversion were found to be signifi cant factors for any and major complications.• The 90-day mortality rate was 2%, which is compatible with reports from Western high-volume centres.

Aim : To evaluate the incidence, nature and prognosis of multiple primary malignancies involving renal cell carcinoma (RCC) in Japan. Methods : Between 1975 and 1998, 319 patients underwent an operation for RCC at Hokkaido University, Sapporo, Japan. The incidence of other primary malignancies was determined and classified as antecedent, synchronous or subsequent. Follow-up was obtained by thorough chart review or telephone interview, and ranged from 0 to 276 months (median 49.0 months). To analyze the influence of other primary malignancies on prognosis, overall and cause-specific survival rates of the patients with an antecedent or synchronous malignancy were compared to the remaining patients.Results : Of the 319 patients there was at least one other malignancy in 38 patients (12%). Four patients had two other malignancies. The other malignancies were antecedent in 13, synchronous in 19 and subsequent in 10 patients. Twenty-two patients had gastrointestinal cancer. In cases of antecedent or synchronous diagnosis of other primary malignancies, RCC was commonly incidental, small or low-stage. Multivariate analysis using Cox's proportional hazards model showed that, for overall survival, the presence of other antecedent or synchronous malignancies was the second most significant prognostic factor, following the pathological stage of RCC. Conclusions : In Japanese patients with RCC, the incidence of other primary malignancies was not uncommon and these malignancies contributed to the prognosis of these patients. Therefore, the malignant potential of individual tumors should be paid careful attention in the management of these patients.

Background : The objective of this study was to retrospectively investigate the effectiveness of adjuvant combination chemotherapy for locally advanced urothelial cancer. Methods : Between 1987 and 1998, 56 patients with locally advanced bladder ( n = 27) or upper urinary tract ( n = 29) cancer (pathological stage T3, T4 or N1, N2 and M0) were treated by radical cystectomy or radical nephroureterectomy and regional lymphadenectomy. Thirty-one patients had lymph node-positive disease and 25 patients did not. Twenty patients underwent adjuvant chemotherapy and 36 patients were observed after surgery. Cox proportional hazards models were used to determine the impact of numerous clinicopathological findings on survival. A subgroup analysis of patients with lymph node-positive disease was conducted to evaluate disease-free survival and overall survival rates.Results : In this series, the median follow-up period was 39 months (range, 4-163) after surgery. Disease-free and overall survival rates of all 56 patients were 45% and 58%, respectively, at 3 years. Only lymph node status was significantly associated with disease-free and overall survival in the multivariate analyses. In a subgroup analysis of patients with lymph node-positive disease, 16 patients who underwent adjuvant chemotherapy had superior disease-free survival compared to 15 patients with no adjuvant chemotherapy ( P = 0.0376). Conclusion : These findings show that the prognosis of advanced urothelial cancer is significantly associated with nodal status. Furthermore, adjuvant combination chemotherapy has a positive impact on survival in patients with lymph node-positive disease.
