Radiation therapy delivered with hypofractionation, which involves the delivery of a higher dose per fraction in fewer fractions (generally with a lower total nominal dose) over a shorter overall treatment time, is an established therapeutic option at least for a selected group of early breast cancer patients after breast-conserving surgery. Optimal delivery of the tumor bed boost dose in terms of timing, fractionation, and total dose whenever a hypofractionated schedule is employed has yet to be established. We herein present a review of the current evidence on the role of boost integration in whole breast radiotherapy.
大分割放疗是指在更短的总治疗时间内,每次分割给予更高剂量(通常总标称剂量较低)、分割次数更少的放疗方式,至少对于保乳手术后特定的早期乳腺癌患者群体而言,这是一种既定的治疗选择。在采用大分割放疗方案时,肿瘤床推量剂量在时间、分割方式和总剂量方面的最佳给予方式尚未确定。我们在此对当前关于推量整合在全乳放疗中作用的证据进行综述。
