Abstract
OBJECTIVES: The aim of this study was to assess the effect of early weight loss before the onset of radiation esophagitis on overall survival (OS) in patients with non-small cell lung cancer treated with concurrent chemoradiotherapy. METHODS: Characteristics (e.g., patient weight, radiation esophagitis score, sex, World Health Organization performance status, chemotherapy dose, nodal status, and gross tumor volume) of 151 patients who received concurrent chemoradiotherapy (in 2006-2013) were retrospectively correlated with OS. Early weight loss was defined as weight loss of more than 5% between the start and third week of radiotherapy in patients whose weight was stable before treatment initiation. RESULTS: In 17% of the patients early weight loss was observed. Median OS (95% confidence interval [CI]) was significantly shorter in the early weight loss group (OS = 13.0 months, 95% CI: 2.0-24.0) versus in the non-early weight loss group (OS = 23.0 months, 95% CI: 14.7-31.3) (hazard ratio [HR] = 1.8, 95% CI: 1.12-2.96, p = 0.017). On multivariate analysis sex (HR = 2.1, 95% CI: 1.33-3.29, p = 0.001), World Health Organization performance status (HR = 1.9, 95% CI: 1.20-2.97, p = 0.006), nodal status (HR = 2.9, 95% CI: 1.38-6.01, p = 0.005), and early weight loss (HR = 1.9, 95% CI: 1.10-3.19, p = 0.022) were associated with OS. CONCLUSIONS: Early weight loss in patients with non-small cell lung cancer was found to be associated with worse prognosis. These data warrant further investigation into the efficacy of tailored intervention to prevent early weight loss.
