摘要
Intraoperative radiotherapy （IORT） in its broadest sense refers to the delivery of radiation at the time of an opera- tion. It includes multiple techniques, namely intraoperative electron irradiation, intraoperative brachytherapy and intraopera- rive photon irradiation. It has a wide range of existing and potentially enlarging clinical applications. We will discuss in this review the rationale for and use of intraoperative irradiation in conjunction with surgical exploration with or without external- beam irradiation （EBRT） and chemotherapy.
