Propensity score-based comparison of survival and radiation pneumonitis after definitive chemoradiation for esophageal cancer: Intensity-modulated radiotherapy versus three-dimensional conformal radiotherapy

Radiation therapy plays a critical role in the treatment of esophageal cancer (EC), especially for locally advanced EC [1]. Historically, three-dimensional conformal radiotherapy (3DCRT) has been the most widely used radiation technique for EC. Based on inverse planning algorithm and complex modulated beams, IMRT can provide improved target coverage and better sparing of organs at risk (OARs) [2]. Therefore, as an advanced conformal radiation modality, intensity-modulated radiotherapy (IMRT) has been increasingly adopted worldwide over the past decade [3,4].
