Randomised trial testing dose escalated, intensity-modulated radiotherapy for women treated by breast conservation surgery and appropriate systemic therapy for early breast cancer
Disease site: Breast cancer
Treatment modality: Radiotherapy
Status: In follow up
IMPORT HIGH is a phase III, prospective, randomised controlled trial to test whether dose escalated, intensity-modulated radiotherapy after conservation surgery for early breast cancer could reduce radiotherapy side effects, whilst maintaining or increasing cancer cure, in women with higher than average local recurrence risk.
IMPORT HIGH closed to recruitment in September 2015 after recruiting 2,621 patients from UK hospitals. Participants were randomised to one of three groups. Those allocated to either of the two treatment arms received varying doses of radiotherapy across the breast with a concomitant boost dose to the tumour bed, while patients in the control arm received standard radiotherapy. Participants are now being followed up for a further 10 years.
