PURPOSE: The aim of this retrospective study was to evaluate inflammation-based scoring as a prognostic factor for operable non-small-cell lung cancer (NSCLC) in elderly patients. METHODS: We collected preoperative data from 108 patients aged above 80 years with NSCLC. Inflammation-based scoring systems, including the C-reactive protein to albumin ratio (CAR) and the Glasgow prognostic score (GPS), as well as other clinicopathological factors, were evaluated as potential prognostic factors. RESULTS: The median patient age was 82 (range 80-93) years and the 5-year overall and disease-specific survival rates were 49.7 and 73.9%, respectively. The cut-off value for CAR was calculated using a receiver operator characteristics analysis and patients were dichotomized accordingly. Patients with a low CAR had significantly higher overall survival than those with a high CAR (<0.028; 65.2% vs. ≥0.028; 31.0%, respectively; p < 0.01). In univariate analysis, female gender, a low Charlson comorbidity index of 0 or 1 and a low CAR were significantly identified in overall survival. On multivariate analysis, a low CAR (p = 0.03, hazard ratio: 2.13, 95% confidence interval 1.074-4.295) was identified as a significant prognostic factor. CONCLUSIONS: The preoperative CAR is a useful predictor of overall survival and could be a simple prognostic tool to help identify resectable NSCLC in elderly patients.
