Summary: | Marital status is viewed as an independent prognostic factor for survival in various cancer types. However, its role in primary liver cancer has yet to be thoroughly explored.
To investigate the impact of marital status on survival outcomes among liver cancer patients.
We finally identified 40,809 eligible liver cancer patients between 2004 and 2012, including 21,939 (53.8%) patients were married at diagnosis and 18,870 (46.2%) were unmarried (including 5,871 divorced/separated, 4,338 widowed and 8,660 single). Married patients enjoyed overall and cause-specific survival outcomes compared with patients who were divorced/separated, widowed, single, respectively. The survival benefit associated with marriage still persisted even after adjusted for known confounders. Widowed individuals were at greater risk of overall and cancer-specific mortality compared to other groups. Similar associations were observed in subgroup analyses according to SEER stage.
We used the Surveillance, Epidemiology and End Results (SEER) database to identify 40,809 patients diagnosed with primary liver cancer between 2004 and 2012. Kaplan-Meier analysis and Cox regression were performed to identify the influence of marital status on overall survival (OS) and liver cancer-specific survival (CSS).
In primary liver cancer patients, married patients enjoyed survival benefits while widowed persons suffered survival disadvantages in both overall survival and cancer-specific survival. |
