摘要

Objective: To evaluate the effects of health insurance status on long-term cancer-specific survival of non-small cell lung cancer(NSCLC) in Beijing, China, using a population-based cancer registry data.Methods: Information on NSCLC patients diagnosed in 2008 was derived from the Beijing Cancer Registry.The medical records of 1,134 cases were sampled and re-surveyed to obtain information on potential risk factors.Poorly-insured status was defined as Uninsured and New Rural Cooperative Medical Insurance Scheme(NRCMS),while well-insured included Urban Employees Basic Medical Insurance(UEBMI) and Free Medical Care(FMC).To estimate survival outcomes, individuals were followed-up until December 31, 2018. Cancer-specific survival probabilities at 5 and 10 years after diagnosis were estimated using the Kaplan-Meier method. Log-rank test was used to compare long-term survival with different characteristics. Multivariable Cox proportional hazard regression model was used to examine the relative effect of insurance status on cancer-specific mortality.Results: Well-insured NSCLC patients have longer cancer-specific survival than poorly-insured individuals[hazard ratio(HR)=0.81;95% confidence interval(95% CI): 0.67-0.97), even after adjusting for age, gender, cancer stage, smoking status, family history and residential area. Older age and rural residence were associated with a higher risk of cancer-specific mortality(HR=1.03;95% CI: 1.02-1.03 and HR=1.25;95% CI: 1.07-1.46,respectively). Smoking individuals had a 41% higher long-term cancer-specific mortality risk than non-smoking ones(HR=1.41;95% CI: 1.20-1.66).Conclusions: NSCLC patients with good insurance status had better survival rates than those with poor insurance. An association was significant even after 10 years. Large population-based studies are needed to validate that high reimbursement insurance status can lead to the improvement of long-term cancer prognosis in China.
