Long-term follow-up data from the FAST trial (10-year analysis) demonstrated that the 28.5 Gy/5-fraction regimen exhibited comparable adverse effects to the conventional 50 Gy/25-fraction regimen, with no statistically significant differences in photographic cosmetic assessments at 2 and 5 years post-treatment. The FAST-Forward trial demonstrated comparable 5-year ipsilateral breast tumor recurrence rates (IBTR) and incidence of radiation-related toxicities between ultra-hypofractionated whole-breast irradiation (UH-WBI; 26 Gy in 5 fractions over 1 week) and moderately hypofractionated whole-breast irradiation (MH-WBI; 40 Gy in 15 fractions over 3 weeks). Additionally, no statistically significant difference in cosmetic outcomes was observed between the two regimens at the 2-year follow-up.\n\nProton radiotherapy enables precise dose delivery to tumor targets while minimizing radiation exposure to surrounding normal tissues, thereby reducing treatment-related toxicities. However, current clinical protocols predominantly employ conventional fractionation for proton therapy, with a paucity of robust evidence evaluating the efficacy and safety of ultra-hypofractionated proton radiotherapy in breast cancer patients. This prospective randomized controlled trial aims to establish high-level scientific evidence for the clinical application of ultra-hypofractionated proton radiotherapy following BCS, ensuring non-inferiority in oncologic control, toxicity profiles, and cosmetic preservation compared to standard regimens.'}, 'eligibilityModule': {'sex': 'FEMALE', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '40 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
