Overview
Brief Summary
We hypothesize that the combination of mammography and CE-MRI will improve the surgeon and radiologist's ability to define extent of disease prior to surgical resection, improve the odds of obtaining clear surgical margins, and increase the efficacy of IORT delivered immediately after initial surgical resection. In this investigation, we will determine whether or not patients deemed eligible for 'immediate" IORT based on mammography and CE-MRI can be successfully treated without the need for re-excision or additional radiotherapy due to inadequate surgical margins.

Eligibility Criteria
Inclusion Criteria
- •Patients with biopsy-proven DCIS, mammographic and CE-MRI evidence of DCIS measuring great then equal to 4cm, and a desire to receive breast conserving therapy, will be considered for participation in this study.
- •Patient history, physical examination findings, and demographics (sex, age, height, weight, bra size, etc.) will be performed and documented.
- •Inclusion Criteria for Initial Registration (all patients cohorts):
- •All cohorts
- •Signed informed consent and HIPAA documents
- •Female sex
- •Age great then equal to 40 years
- •Localized ductal carcinoma in situ
- •Clinically and/or histologically negative axillary lymph nodes
- •No imaging or clinical findings suggestive of invasive carcinoma.
Exclusion Criteria
- •Age less than 40
- •DCIS associated with any evidence of microinvasion or invasive carcinoma on pre-operative imaging or core biopsy of the breast or axillary nodes.
- •DCIS that is multicentric in the ipsilateral breast. Multicentricity will be defined at 2 or more lesions separated by more than 3 cm in the same breast.
- •Non-epithelial breast malignancies such as sarcoma or lymphoma

- •Pregnancy or lactation
- •Collagen vascular diseases, including Systemic lupus erythematosus, Systemic sclerosis (scleroderma), CREST Syndrome (calcinosis, Raynaud phenomenon, esophageal dysfunction, sclerodactyly, telangiectasia, and the presence of anticentromere antibodies), polymyositis, dermatomyositis with a CPK level above normal or with an active skin rash, inclusion-body myositis, or amyloidosis
- •Serious psychiatric or addictive disorders
Outcomes
Primary Outcomes
Reoperation (Re-excision or Mastectomy) Rates Following WLE or IORT
Time Frame: 30 days
These are the rates of reoperation for re-excision or mastectomy following Wide Local Excision (WLE) or Intraoperative Radiation Therapy (IORT). The number of patients who required reoperation were reported below.
Secondary Outcomes
