The phase II randomized trial of conventional versus hypofractionated proton radiotherapy investigated whether condensing treatment to 15 fractions would be safe based on evidence that breast cancer is more sensitive to higher dose fractions than surrounding normal tissues. In this touchONCOLOGY interview, we speak with Dr Robert Mutter (Mayo Clinic Rochester, MN, United States) provides an overview of this trial and the impact of the findings.
The abstract entitled ‘Phase II randomized trial of conventional versus hypofractionated post-mastectomy proton radiotherapy’ was presented at San Antonio Breast Cancer Symposium (SABCS), 06–10, December, 2022.
