Progress in Research of Adaptive Radiation Therapy for Head and Heck Cancer / 昆明医科大学学报

ABSTRACT

Radiotherapy is one of the most important treatment method for head and neck cancer.The intensity-modulated radiotherapy (IMRT) has better conformal property and uniformity.IMRT is gradually replacing conventional radiation therapy and has become the mainstream radical treatment for head and neck cancer.During IMRT,the patient treatment positioning,inter-treatment,and intra-treatment variation of organ position,size,and shape impact the accuracy of radiation dose delivery.This method may cause target less and (or) additional complications.Adaptive radiotherapy (ART) is a new radiotherapy technology.Based on the patient's pre-treatment images and relative information such as dose deviation,ART can able to compensate the target coverage and clinical outcome.Under the help of ART technique,radiotherapy can be more accurate and more personalized.This paper reviews the research status of ART technology in head and neck cancerby retrospective studying the related literature at home and abroad.
