Effect of Marital Status on Survival of Lung Cancer Patients Investigated Based on SEER Database

Objective To assess the effect of marital status on the survival of patients with lung cancer.

Methods Kaplan-Meier test and Log rank test were used for the univariate analysis of gender, age, race, surgery or not, tumor grade, TNM degree and marital status. In multivariate analysis, Cox regression was used to analyze the all-cause mortality of patients with lung cancer under different marital status.

Results Married patients had higher survival rate(34.5%) than those who were never married(28.9%), widowed(28.3%) and divorced or separated(32.6%) in the univariate analysis. We could find the same results in the multivariate analysis.

Conclusion Marital status could affect the survival of lung cancer patients.
