    Abstract:
    (Objectives) We retrospectively investigated the prognostic factors and the role of adjuvant chemotherapy against upper tract urothelial carcinoma (UTUC) after surgery. (Materials and methods) 343 patients of UTUC who underwent radical nephroureterectomy at Jikei University Hospital and affiliated institutions between January 2004 and February 2012 were retrospectively analyzed. A chi-squared test was used for categorical variables. Survival probabilities after surgery were estimated using the Kaplan-Meier method. Multivariate Cox regression models addressed overall survival and cancer-specific survival after surgery. (Results) The 5-year overall and cancer-specific survival rates were 64.6% and 74.6%, respectively. On multivariate analysis, higher age, male, higher pT-stage and lymphovascular invasion (LVI) were associated with worse overall survival and higher pT-stage and LVI were associated with worse cancer-specific survival. 44 patients (G3 and ≥pT3) who received cisplatin-based adjuvant chemotherapy had improved overall survival (P=0.044). (Conclusions) Higher pT-stage, LVI were important prognostic variables associated with oncologic outcomes. Cisplatin-based adjuvant chemotherapy offered a significant benefit to overall survival in high risk UTUC (G3 and ≥pT3), but more investigations are needed to confirm its utility.
