We therefore strove to explore the impact of dynamic changes in marital status on the prognosis of breast cancer patients. We selected patients meeting the eligibility criteria from the Surveillance, Epidemiology, and End Results cancer database. We then used multivariate Cox proportional hazard regression model to analyze the effect of dynamic changes in marital status on the prognosis of overall survival (OS) and breast cancer-specific special survival (BCSS). Compared with the patients in the Single–Single group and the divorced/separated/widowed–divorced/separated/widowed (DSW–DSW) group, patients in the Married–Married group were significantly associated with better BCSS (HR 1.13, 95% CI: 1.03–1.19, P < 0.001; HR 1.19, 95% CI: 1.14–1.25, P < 0.001, respectively) and OS (HR 1.25, 95% CI: 1.20–1.30, P < 0.001; HR 1.49, 95% CI: 1.45–1.54, P < 0.001, respectively). In contrast to the DSW–DSW group, the Single–Single group and the DSW–Married group showed similar BCSS (HR 0.98, 95% CI: 0.92–1.05, P = 0.660; HR 1.06, 95% CI: 0.97–1.15, P = 0.193, respectively) but better OS (HR 1.14, 95% CI: 1.09–1.19, P < 0.001; HR 1.32, 95% CI: 1.25–1.40, P < 0.001, respectively). Compared with the Single–Single group, the Single–Married group showed significantly better BCSS (HR 1.21, 95% CI: 1.07–1.36, P = 0.003) but no difference in OS (HR 1.08, 95% CI: 0.98–1.18, P = 0.102); In contrast to the Married–DSW group, the Married–Married group exhibited better BCSS (HR 1.11, 95% CI: 1.05–1.18, P < 0.001) and OS (HR 1.27, 95% CI: 1.22–1.32, P < 0.001). Our study demonstrated that, regardless of their previous marital status, married patients had a better prognosis than unmarried patients. Moreover, single patients obtained better survival outcomes than DSW patients. Therefore, it is necessary to proactively provide single and DSW individuals with appropriate social and psychological support that would benefit them.","url":"https://innscience.ca/es/community/literature/1a37b9c3-14e5-4095-8199-2da1ccd26189"}
