Abstract:

OBJECTIVE: This study aimed at evaluating the survival of patients older than 70 with lung cancer and explore the independent prognostic factors in this group of patients. METHODS:The modified cumulative illness rating scale-geriatric(MCIRS-G) was scored for a cohort of elderly patients with lung cancer. Total score (TSC),severity index(SV) and comorbidity index(CM) were obtained. Clinical features were also used. All patients underwent a follow-up for mortality. Univariate analysis and multivariate analysis were used to identify factors associated with prognosis in the enrolled patients. RESULTS:The overall median survival was 30.52 months and the incidence of complications was 82.26%. TSC,SV and CM were positively correlated with age(r were 0.656,0.739 and 0.677,respectively,P<0.05). By univariate analysis,age,pathological type,clinical stages,American Eastern Cooperative Oncology Group(ECOG) performance status (PS),differentiation degree,surgery,TSC,SV and CM were significantly related to prognosis and survival in geriatric lung cancer patients(P<0.05). By multivariable analysis,clinical stages,ECOG PS,differentiation degree,surgery,TSC,SV and CM were independent prognostic factors. CONCLUSION:Clinical stages,differentiation degree,comorbidity,ECOG PS and surgery may be independent prognostic factors in the elderly with lung cancer. The MCIRS-G could effectively assess the influence of comorbidities on the prognosis of lung cancer in this patient group.
