Comparison between the use of hypofractionated and conventionally fractionated radiotherapy in early breast cancer: A single-center real-world study in Taiwan.

Background/purpose: This study aimed to analyze the long-term outcomes of hypofractionated whole-breast irradiation (WBI) (HF-WBI) compared with those of conventionally fractionated WBI (CF-WBI) for early breast cancer treated with breast-conservation surgery (BCS) and adjuvant WBI in Taiwan.

Methods: This study included patients treated at our institution between 2012 and 2016. All patients with early breast cancer received BCS (pT1-2, pN0, M0) and adjuvant WBI through one of two treatment schemes.
