Abstract
BACKGROUND: The standard treatment for locally advanced non-small cell lung cancer (NSCLC) is radiotherapy concurrent with chemotherapy, but the survival was not satisfied. With the development of intensity modulated radiotherapy, simultaneous integrated boost technique (SIB) becomes the research direction of locally advanced NSCLC. The aim of this study is to investigate the efficacy and safety of SIB intensity modulated radiotherapy technique for locally advanced NSCLC.Entities:
