BACKGROUND AND PURPOSE: Radiation-esophagitis and weight loss are observed toxicities in patients treated with concurrent chemo- (CT-RT) for non-small cell lung cancer (NSCLC) and might be related. The was to investigate whether weight loss already starts early after CT-RT and precedes radiation-esophagitis. MATERIALS AND METHODS: In a retrospective cohort, weight and esophagitis grade >/=2 were assessed first weeks of (CT-)RT in patients treated with concurrent (n = 102) or sequential (n = 92) therapy. In a prospective validation study, data on weight, esophagitis grade >/=2, nutritional intake and muscle strength obtained before, during and following CT-RT. RESULTS: In the cohort, early weight loss was observed in concurrently treated patients 0.002), independent of esophagitis >/= grade 2. Early weight loss was observed in the prospective cohort (p = 0.003) and was not accompanied decreases in nutritional intake. In addition lower limb muscle strength declined (p = 0.042). In the later weeks of treatment, further body occurred (p < 0.001) despite increased nutritional supplementation and weight was only partly recovered after 4 weeks post CT-RT (p = 0.003). CONCLUSIONS: Weight loss during concurrent CT-RT for NSCLC starts early to onset of esophagitis, requiring timely and intense nutritional
