Fasting Blood Glucose Level in Locally Advanced Non-Small Cell Lung Cancer: a New Prognostic Factor?

In this study, the effect of hyperglycemia on overall survival (OS), disease-free survival (DFS), and locoregional recurrence (LRR) was investigated in NSCLC. One stage IIIA-IIIB NSCLC patient treated with chemoradiotherapy between 2010 and 2015 was enrolled. Fasting blood glucose (FBG) levels were recorded in pre-treatment, treatment, and post-treatment periods. Median age was 54  years (51–62). Fifty-two patients had squamous cell carcinoma (SCC); 19 had adenocarcinoma. Median follow-up was 19 (11–30), median survival was 19 (13–24), and DFS was 9 (7–11) months. Diabetic patients had shorter survival than non-diabetics 12 (95%CI, 10–14) vs. 25 months (95%CI,18– 32),p  = 0.005. Number of patients with LRR was also higher in diabetics compared to non-diabetics (8/12 vs. 11/37,p = 0.039). OS was shorter in patients with hyperglycemic-FBG and diabetic-FBG levels in pre-treatment period (log-rankp = 0.03 and 0.023, respectively). Diabetic-FBG level in pre-treatment period was found to be the only independent risk factor for survival. In subgroup analysis, these differences were apparent in SCC (log-rankp = 0.009 for hyperglicemic, log-rankp = 0.017 for diabetic-FBG). LRR was 68% in patients with diabetic-FBG, 36.5% in patients with non-diabetic-FBG in post-treatment period (p = 0.015). Patients with LRR had significantly higher median FBG value in post-treatment period compared to non-relapsing patients, 138 mg/dL (119–228) and 111 mg/dL ...
