UNASSIGNED: 73 Background: Analysis from population-based @entity5 registry data has suggested that being married is associated with improved survival in @entity1 with @entity263 . However, a limitation of such analysis is the inability to control for PSA or medical comorbidity which may differ by marital status. We investigated the association between marital status and both @entity263 specific mortality (PCSM) and overall mortality (OM) in @entity1 treated with radical prostatectomy. METHODS: The study population included 3596 @entity1 treated with radical prostatectomy at a single institution between 1994 and 2004 and followed for a median of 72 months. Disease specific factors (PSA, clinical stage, and biopsy Gleason grade), comorbidity (validated ACE-27 comorbidity index), ethnicity, age, and marital status at time of treatment were retrieved from an institutional @entity5 registry. Differences between marital status groups were evaluated by Chi square or ANOVA. Multivariable Cox proportional hazard regression models were used to estimate the hazard ratio (HR) of PCSM and OM by marital status. RESULTS: 86.9% of @entity1 were married, 5.3% divorced, 2.4% widowed, and 5.5% never married. Marital status was associated with differences in PSA (p<0.01), comorbidity (p=0.04), and age (p<0.01). Married @entity1 had the lowest mean PSA at diagnosis and never married @entity1 were younger and the most likely to have no known medical comorbidity. A total of 386(11%) @entity1 were dead at the end of follow up, but only 55 of them died of @entity263 . In multivariable analyses (Table), never married @entity1 had a significantly increased risk of PCSM and OM compared to married @entity1 , whereas no additional risk was observed for divorced or widowed @entity1 . CONCLUSIONS: Never married @entity1 had an increased risk of PCSM and OM. Factors associated with social isolation or unhealthy behaviors may have a detrimental effect on survival after prostatectomy. [Table: see text].
