Research progress on application of simultaneous integrated boost intensity-modulated radiotherapy in esophageal carcinoma / 中华放射肿瘤学杂志

ABSTRACT

In recent years, unconventional fractionated radiotherapy has shown increasing advantages in the treatment of multiple system tumors. Simultaneous integrated boost intensity-modulated radiotherapy (SIB-IMRT) involves the delivery of standard-fraction doses of radiotherapy to different areas, achieving the delivery of higher doses of radiotherapy per fraction to the high-risk gross tumor volume (GTV) without sacrificing the irradiation dose to the normal tissues. The dosimetric advantages of SIB-IMRT have been widely recognized. At present, the local control, survival advantage, indication population and the optimal upper limit of single fraction of SIB-IMRT for esophageal carcinoma are still unclear. This article reviews the application of SIB-IMRT in esophageal carcinoma.
