Abstract:
BACKGROUND:Both lung cancer and cardiometabolic diseases are leading causes of death in China, and they share some common risk factors. However, the prevalence and long-term effect of pre-existing cardiometabolic comorbidities (CMCs) on the survival of middle-aged and elderly lung cancer patients are still not clear.
METHODS:We consecutively recruited 3477 non-small cell lung cancer (NSCLC) patients between January 2011 and December 2018 from four cancer specialty hospitals in China. Univariable and multivariable adjusted Cox proportional hazard models were conducted to evaluate the risk factors associated with mortality. Hazard ratio (HR) for mortality and corresponding 95% CI were calculated.
RESULTS:The prevalence of CMCs was 30.0% in middle-aged NSCLC patients and 45.5% in elderly NSCLC patients. Log-rank analysis presented statistically significant differences in median survival time between patients with CMCs and without CMCs in both the middle-aged group (21.0 months vs. 32.0 months, P < 0.01) and the elderly group (13.0 months vs. 17.0 months, P = 0.01). Heart failure (HR = 1.754, 95% CI: 1.436-2.144, P < 0.001) and venous thrombus embolism (HR = 2.196, 95% CI: 1.691-2.853, P < 0.001) were independent risk factors for the survival of middle-aged NSCLC patients, while heart failure (HR = 1.709, 95% CI: 1.371-2.130, P < 0.001) continued to decrease overall survival in the elderly group. Hyperlipidemia may be a protective factor for survival in middle-aged group (HR = 0.741, 95% CI: 0.566-0.971, P = 0.030).
CONCLUSIONS:Our findings demonstrate for the first time the prevalence and prognostic value of pre-existing CMCs in Chinese middle-aged and elderly NSCLC patients.
