Research progress of hypofractionated whole breast irradiation after breast conserving surgery / 国际肿瘤学杂志

ABSTRACT

Hypofractionated radiotherapy after breast conserving surgery has become a new standard treatment of early breast cancer. Clinical researches show that α/ β value of breast cancer is lower than that of other tumors,and the breast cancer is more suitable for hypofractionated radiotherapy. Hypofractionated radio-therapy has good economic benefits,and long-term follow-up results from a number of classical randomized con-trolled studies have shown that hypofractionated whole breast irradiation is effective and safe. With the extensive application of hypofractionated irradiation,this technology has been gradually extended to regional nodal irradia-tion,postmastectomy radiotherapy and breast ductal carcinoma in situ.
