RESUMEN
AIM: To evaluate the effect of marital status on survival of patients with vulvar cancer. MATERIALS & METHODS: A total of 4001 patients with vulvar cancer were included from the SEER database. Statistical analyses were performed using χ2 test, Kaplan-Meier method, Cox regression proportional hazards and a 1:1 propensity score-matching. RESULTS: The 8-year vulvar cancer-related survival in married, divorced, single and widowed patients were 78.6, 82.2, 78.9 and 61.6%, respectively (p < 0.001). In multivariate analysis, widows patients had significantly worse vulvar cancer survival than the nonwidowed counterparts in unmatched and matched populations. CONCLUSION: Being widowed is associated with greater risk of vulvar cancer mortality than the nonwidowed counterparts.
