Brief Summary
The purpose of this research study is to see if a participant's nipple and areola can be safely preserved by adding radiation to these areas after a nipple-sparing mastectomy and immediate breast reconstruction.

Outcome Measures
Primary Outcomes (1)
Maximum Tolerated Dose (MTD) of Prophylactic NAC Irradiation.
The recommended Phase II dose will be reported as the MTD at which only 0 or 1 out of 6 participants experiences dose limiting toxicity (DLT). DLT will be reported as any of the following: Grade 4 skin rash or pain, NAC necrosis, any toxicity requiring interruption of NAC irradiation greater than 2 weeks or any grade 4 or 5 treatment related toxicity. Toxicity will be evaluated by treating physician using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 3.0.
Up to 13 weeks
Secondary Outcomes (4)
Cosmetic Outcome
12 months
Disease-Free Survival Rate in Study Participants
Up to 5 years
Overall Survival Rate in Study Participants
Up to 5 years
Recurrence Rate in Study Participants
Up to 5 years
Study Arms (1)
Phase 1 MTD NAC RT
EXPERIMENTALParticipants will undergo a Nipple-Areolar Complex (NAC)-sparing mastectomy with immediate reconstruction and axillary surgery, if indicated, on Week 1. Anytime between Weeks 5-8, participants will undergo a dose-escalation/de-escalation of prophylactic NAC radiation treatment (RT) twice daily (minimum of 4 hours apart) for 5 days. Dose escalation/de-escalation design are as follows: * Dose Level I - 10 fractions of 2.0 Gy for a total of 20 Gy * Dose Level II - 10 fractions of 2.5 Gy for a total of 25 Gy * Dose Level III - 10 fractions of 3.0 Gy for a total of 30 Gy * Dose Level IV - 10 fractions of 3.5 Gy for a total of 35 Gy Participants will be treated between cohorts of 2-6 patients per dose level starting at dose level II. Dose escalation stops when 2 out of 2-6 participants encounter Dose Limiting Toxicities (DLT). Standard of care chemotherapy, at treating physician's discretion, can be initiated 2 weeks after RT.
Interventions
Subcutaneous Mastectomy (SCM) to be performed, preserving the nipple and areola complex, after a frozen section of the tissue underneath the nipple-areola complex is sampled and found to be negative for tumor. Performed during Week 1.
Immediate reconstruction of the breast will be performed (after Nipple-Sparing Mastectomy) by the plastic surgeon, type depend on surgeon's discretion and patient's desire. Performed during Week 1.
Axillary Dissection or Sentinel Node Biopsy (SNB) will be performed at surgeon's discretion.
Prophylactic Nipple-Areolar Complex Radiation Therapy per protocol. Administered between weeks 5 to 8.
Eligibility Criteria
You may qualify if:
- Patients must have histologically confirmed in-situ or invasive breast carcinoma.
- Tis, T1, T2 invasive or non-invasive carcinoma of the breast; lesion less than 4 cm.
- Unifocal, multifocal or multicentric breast cancers that can be removed by nipple sparing mastectomy with negative surgical margins.
- No extensive intraductal component or patient with distant metastases.
- Patients must be \> 18 years of age.
- No concomitant or history of nipple discharge or skin involvement.
- No prior history of malignancy (less than 5 years prior to study entry), except non-melanomatous skin cancer.
- No prior history of radiation to the chest.
- No collagenous disease (systemic lupus erythematosis, scleroderma, dermatomyositis)No previous non-hormonal therapy including radiation or chemotherapy for current breast cancer.
- No patients with Paget's disease of the nipple.
- No patients with co-existing medical conditions with life expectancy \< 2 years.
- No pregnant or lactating women.
- Eastern Cooperative Oncology Group (ECOG) 0 - 2.
- Signed study-specific informed consent form prior to the study entry.
You may not qualify if:
- Retroareolar breast cancer lesions within one cm, depth from the skin surface.
- Concomitant or history of nipple discharge or skin involvement.
- Patient with distant metastases.
- Patient with extensive intraductal carcinoma.
- Any previously irradiated ipsilateral breast cancer.
- Patients with Paget's disease of the nipple.
- Patients with collagenous diseases, as systemic lupus erythematosis, scleroderma or dermatomyositis.
- Other malignancy, except nonmelanomatous skin cancer, less than 5 years prior to participation in this study.
- Patients who are pregnant or lactating due to potential exposure of the fetus to RT and unknown effects of RT to lactating females.
- Positive surgical margins following nipple sparing mastectomy.
