  Objective: Optimal patient selection for adjuvant chemotherapy has not been clarified in upper urinary tract urothelial cancer (UTUC). We aimed to develop a risk model to select candidates for adjuvant chemotherapy after radical nephroureterectomy (RNU). Methods: A retrospective review of 936 patients with UTUC between 1995 and 2015 who received ≥ 2 cycles of platinum-based adjuvant chemotherapy after RNU (n=213) or surgery alone (n=723) was conducted in collaborative institutions. Risk factors for cancer-specific mortality were extracted using the proportional hazard model. The survival benefit in high-risk patients was compared between the groups. Results: At a median follow-up of 1006 days (34 months), disease recurrence, cancer-specific mortality, and allcause mortality were noted in 253 (27.5%), 206 (22.0%).. View More»
