PURPOSE: Despite being the leading cause of cancer death, no prior studies have characterized survival patterns among Chinese Americans diagnosed with lung cancer. This study was conducted to identify factors associated with survival after lung cancer in a contemporary cohort of Chinese patients with lung cancer.METHODS: The study design is a prospective descriptive analysis of population-based California Cancer Registry data. Multivariable Cox proportional hazards models were used to estimate hazard ratios (HRs) for overall mortality. Participants were Chinese American residents diagnosed with first primary invasive lung cancer from 2000 to 2010 (2,216 men and 1,616 women).RESULTS: Among Chinese men, decreased mortality was associated with care at a National Cancer Institute cancer center (HR, 0.85; 95% CI, 0.73 to 0.99) and adenocarcinoma versus small-cell carcinoma (HR, 0.78; 95% CI, 0.65 to 0.92). Women had better survival compared with men (HR, 0.82; 95% CI, 0.75 to 0.89), with mortality associated with never married versus currently married status (HR, 1.36; 95% CI, 1.11 to 1.66), lower versus higher neighborhood socioeconomic status (HR, 1.38; 95% CI, 1.10 to 1.72 comparing lowest to highest quintile), care at a cancer center (HR, 0.80; 95% CI, 0.67 to 0.96), and squamous cell relative to small-cell carcinoma (HR, 1.60; 95% CI, 1.04 to 2.48).CONCLUSION: Focusing on factors associated with marital status, community socioeconomic status, and characteristics unique to National Cancer Institute-designated cancer centers may help to identify potential strategies for improving the length of survival for Chinese Americans.
