Abstract

OBJECTIVE:

Previous studies have suggested that marital status is associated with survival from lung cancer; however, its association is not conclusive. The association between marital status and survival in Japanese patients with non-small cell lung cancer (NSCLC) was prospectively investigated.

METHODS:

Between July 1999 and July 2004, a total of 1230 NSCLC patients were enrolled. The baseline survey consisted of the collection of clinical information and various demographic data, including marital status. A Cox regression model was used to estimate the hazards ratio (HR) of all-cause mortality adjustments for age, BMI, education level, performance status, histology type, clinical stage, smoking status, choice of definitive treatment, and depression.

RESULTS:

The multivariable adjusted HR of male widowed patients versus male married patients was 1.7 (95% confidence interval=1.2-2.5, p=0.005). However, no significant increased risk of death in female widowed patients compared with female married patients was observed (HR=0.7, 95% confidence interval=0.5-1.1, p=0.15). With regard to separated/divorced and single patients no significant increased risk of death in male and/or female compared with married patients was observed.

CONCLUSIONS:

The present data suggest that male widowed patients with NSCLC have a higher mortality rate than male married patients with NSCLC, after controlling for various factors.
