Sumario:BACKGROUND: Marital status has been considered as an independent prognostic factor for various types of cancer survival. The objectives of our study were to investigate the function of marital status on the survival of upper tract urothelial carcinoma (UTUC) patients. METHODS: The patients diagnosed with UTUC between 1988 and 2015 were captured within the Surveillance, Epidemiology, and End Results (SEER) database. Patients were classified into married, divorced/separated, widowed and single cohorts. Kaplan-Meier and Cox regression analysis was conducted to assess the effects of marital status on overall survival (OS) and cancer-specific survival (CSS). A 1:1 matched‐pair analysis was performed to optimize the final statistical results by propensity score matching (PSM). RESULTS: Among the 10,852 eligible patients, the percentage of married, divorced/separated, widowed and single patients accounted for 58.2% (6,321), 9.0% (980), 23.3% (2,526) and 9.4% (1,025) respectively. The widowed patients had the worst OS and CSS. Marital status was a predictive factor for OS and CSS of UTUC patients. The results of multivariate Cox regression showed that the worst OS [hazard ratio (HR): 1.41; 95% confidence interval (CI): 1.33–1.49, P<0.001] and the poorer CSS (HR: 1.32; 95% CI: 1.22–1.43, P<0.001) were existed in the widowed patients, compared with married patients. The results of the stratified analysis by primary site also indicated the same conclusion. Furthermore, the results were confirmed in the 1:1 matched group. CONCLUSIONS: Marital status acted as an independent prognostic and protective factor for survival in UTUC patients. Additionally, being widowed was related with a high risk of death in UTUC compared with married, divorced, or single patients.
