肿瘤术中放疗的研究进展

术中放疗(IORT)是指在手术过程中用放疗设备对原发肿瘤瘤床、残存灶和淋巴引流区等部位施行近距离单次大剂量照射的一种放疗方法,包括术中电子束技术和高剂量率腔内照射。目前,给予精确的放疗剂量是当代多学科个体化肿瘤治疗的重要组成部分,而IORT正是由于使靶区内剂量最大化而尽可能的保护了周围的正常组织实现了精准治疗。现就目前关于术中放疗的研究进行综合性阐述。

Research progress in intraoperative radiotherapy for tumor

Intraoperative radiotherapy (IORT) is a radiotherapy method that uses a radiotherapy device to provide a brachytherapy with single high-dose radiation to a target tissue (primary tumor beds, residual tumors, and lymphatic drainage areas) during surgery, which includes intraoperative electron beam radiotherapy and high-dose-rate intraluminal brachytherapy. Nowadays, the implementation of precise radiation dose is an important part of multidisciplinary, individualized treatment of tumors. IORT achieves precise treatment by maximizing the radiation dose to the target volume and protecting surrounding normal tissues as much as possible. This article describes the recent research on IORT.
