Patient preferences regarding intraoperative versus external beam radiotherapy for early breast cancer and the impact of socio-demographic factors.

Our study confirms the existence of subgroups of breast cancer patients who would accept an additional risk of recurrence associated with choice of radiation modality to receive a single dose of IORT as adjuvant radiotherapy for breast cancer instead of EBRT over several weeks; yet our data fail to identify a single factor significantly associated with these patient preferences and, therefore, helpful for individualised decision-making processes.
