术中放射治疗(以下称术中放疗)是放射治疗的一种方式,相比体外照射,术中放疗是在手术过程中进行的放射治疗,即在直视状态下对可见的肿瘤、肿瘤瘤床区或容易复发转移的部位进行单次的大剂量照射,达到控制肿瘤的目的,同时能最大限度地保护正常组织,使之少受照射以减少损伤。 Intraoperative radiation therapy (hereinafter referred to as intraoperative radiotherapy) is a method of radiation therapy. Compared with external radiation, intraoperative radiotherapy is radiotherapy performed during surgery, ie, visible tumors and tumors under direct vision. A single large-dose irradiation is performed in the bed area or a site that is likely to relapse and metastasize, so that the purpose of controlling the tumor can be achieved, and at the same time, the normal tissue can be protected to the utmost extent, so that it is less irradiated to reduce the damage.
