Intensity-modulated radiotherapy does not decrease the risk of malnutrition in esophageal cancer patients during radiotherapy compared to three-dimensional conformal radiation therapy

摘要

BackgroundEsophageal cancer is a lethal disease of global scope. Radiotherapy is the main method to treat esophageal cancer; however, it concurrently leads to malnutrition. Intensity-modulated radiotherapy (IMRT) is superior to three-dimensional conformal radiation therapy (3D-CRT) in dosimetry and clinical outcomes. In this cohort study, we aimed to compare the effect of 3D-CRT and IMRT on malnutrition status.
