Official title
Evaluation of Three Fraction Accelerated Partial Breast Irradiation as the Sole Method of Radiation Therapy for Low-risk Stage 0 and I Breast Carcinoma
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The investigators proposed approach allows them to deliver a low total dose of radiation to patients with low-risk, early-stage breast cancer which would further minimize the impact of adjuvant therapy. This work has the potential to revolutionize partial breast irradiation by allowing it to take place at many radiation oncology centers with minimal specialized equipment beyond that commonly available. The investigators first step is this proposed single institution phase I/II study designed primarily to evaluate the tolerance of this approach which the investigators are choosing to call Three Fraction APBI (Tri-APBI).
