Intensity-Modulated Radiotherapy, Not 3 Dimensional Conformal, Is the Preferred Technique for Treating Locally Advanced Lung Cancer

摘要

When used to treat lung cancer, intensity-modulated radiotherapy (IMRT) can deliver higher dose to the targets and spare more critical organs in lung cancer than can 3-dimensional conformal radiotherapy. However, tumor-motion management and optimized radiotherapy planning based on 4-dimensional computed tomography scanning are crucial to maximize the benefit of IMRT and to eliminate or minimize potential uncertainties. This article summarizes these strategies and reviews published findings supporting the safety and efficacy of IMRT for lung cancer. (C) 2015 Elsevier Inc. All rights reserved.
