Real-Time MRI-Guided 3-Fraction Accelerated Partial Breast Irradiation in Early Breast Cancer
Trial Parameters
Brief Summary
This trial will investigate a novel 3-fraction radiation regimen for participants undergoing breast-conserving therapy (BCT) for early breast cancer that will: 1) significantly reduce the duration of treatment and can be completed in one-week (5 working days) and 2) MRI-guided radiotherapy (MRIdian) would limit the volume of normal tissue radiated and therefore resultant toxicity. The hypothesis is that 3-fraction radiation therapy can be delivered safely without compromising the therapeutic ratio. Participants can expect to be on study for follow up up to 5 years.
Eligibility Criteria
Inclusion Criteria: For all participants * Participants should have no contraindications to undergo MRI scan as part of radiotherapy planning and treatment. * Lumpectomy cavity must be clearly visible on CT and MRI scan at radiotherapy simulation. * Pregnancy test negative in women of child bearing potential (WOCBP). * The participant must consent to be in the study and must have signed an approved consent form conforming with institutional guidelines. * Participants with a history of non-breast malignancies are eligible if they have been disease-free for 5 or more years prior and are deemed by their physician to be at low risk for recurrence. Participants with the following cancers are eligible if diagnosed and treated within the past 5 years: carcinoma in situ of the cervix, carcinoma in situ of the colon, melanoma in situ, and basal cell and squamous cell carcinoma of the skin. For participants with Invasive Carcinoma * Suitable: * Age: \>=50 years * Margins: Negative by at least 2
