  • Descrição: •Fractionation preferences in breast cancer patients vary amongst radiation oncologists.•Hypofractionation use was more frequent for WBI, and less for PMRT and RNI.•Radiation oncologists practicing in academic hospitals and/or dedicated to breast cancer more likely use hypofractionation.•Hypofractionation is more used in Western Europe compared to elsewhere in Europe. We aimed to assess the prescription preference about hypofractionated radiation therapy (HFRT) for breast cancer (BC) patients amongst radiation oncologists (ROs) practicing in Europe and to identify restraints on HFRT utilisation. An online survey was circulated amongst ROs in Europe through personal, RO and BC societies’ networks, from October 2019 to March 2020. The statistical analyses included descriptive statistics, chi-squared testing, and logistic regression analysis. We received 412 responses from 44 countries. HFRT was chosen as the preferred schedule for whole breast irradiation (WBI) by 54.7% and for WBI with regional nodes irradiation (RNI) by 28.7% of the responding ROs. In the case of postmastectomy RT with or without reconstruction, HFRT was preferred by 21.1% and 29.6%, respectively. Overall, 69.2% of the responding ROs selected at least one factor influencing the decision to utilise HFRT, the most frequent of which included age (51.4%), RNI (46.9%), internal mammary lymph nodes irradiation (39.7%), BC stage (33.5%) and implant-based breast reconstruction (31.6%). ROs working in academic centres (odds ratio, (OR), 1.7; 95% confidence interval, (CI); 1.1–2.6, p = 0.019), practicing in Western Europe (OR, 4.2; 95%CI; 2.7–6.6, p < 0.0005) and/or dedicating >50% of clinical time to BC patients (OR, 2.5; 95%CI; 1.5–4.2, p = 0.001) more likely preferred HFRT. Although HFRT is recognised as a new standard, its implementation in routine RT clinical practice across Europe varies for numerous reasons. Better dissemination of evidence-based recommendations is advised to improve the level of awareness about this clinical indication.
