The long-term outcome of adjuvant hypofractionated radiotherapy and conventional fractionated radiotherapy after breast-conserving surgery for early breast cancer: a prospective analysis of 107 cases

For patients with early-stage breast cancer, breast-conserving surgery followed by conventional fractionated radiotherapy of the breast region is a standard therapeutic procedure. However, conventional fractionated radiotherapy is normally delivered for 6–7 weeks, which is not convenient. To address this problem, we cautiously evaluated the use of hypofractionated radiotherapy (HF), which has a shortened course of treatment
