Abstract
BACKGROUND: Several inflammation-based scoring systems and nutritional indicators have been shown to have relevance to survival of patients with non-small cell lung cancer (NSCLC).The present study examined preoperative and pathological factors in patients who underwent curative resection for non-small cell lung cancer, with the aim to elucidate risk factors for early recurrence within 1 year of surgery. METHODS: Patients with NSCLC who underwent surgery from January 2009 to December 2014 were retrospectively investigated. Routine laboratory measurements including carcinoembryonic antigen were performed before surgery, and pathological information was collected after surgery. Patients with recurrence within 1 year after surgery were considered as early recurrence group (ERG), those with recurrence after 1 year were as late recurrence group (LRG), and those without recurrence were as no recurrence group (NRG). RESULTS: Multivariate analysis between ERG and LRG revealed Glasgow prognostic score (GPS) and CRP-to-albumin ratio (CAR) as independent risk factors for early recurrence. Multivariate analysis between ERG and LRG + NRG confirmed CAR, vascular invasion, and pathological stage as risk factors for early recurrence. CONCLUSION: These findings indicated that CAR and GPS were confirmed to be risk factors for early recurrence, in addition to pathological factors.
