Brief Summary:
We hypothesize that radiofrequency ablation after single-insertion image guided vacuum assisted biopsy (IVEB) can be used to achieve negative margins in small unicentric breast cancers (≤1.5 cm).

Condition or disease Intervention/treatment Phase
Breast Cancer Procedure: Percutaneous Removal and Margin Ablation Phase 1 Phase 2

Detailed Description:
Using the Mammotome Breast Biopsy System (IVEB) in conjunction with MRI to predict extent of disease, ultrasound to direct removal of the tumor, touch preparation cytology for diagnosis, and ablation of margins using radiofrequency ablation (RFA), we propose to develop a comprehensive system for same-day diagnosis and treatment of patients with small breast lesions.

Arm Intervention/treatment
Experimental: 1 Procedure: Percutaneous Removal and Margin Ablation
Patients with a diagnosis of unicentric invasive breast cancer diagnosed by IVEB will then be assigned to the next available surgery date. On that day, the patient's axillary staging will be done, followed by ablation of the biopsy cavity using RFA. The breast surgery may include lumpectomy (which will be directed with US-guidance to assure more accurate removal of the en bloc IVEB site and the margin zone of ablation) or simple mastectomy with or without reconstruction. The tissue specimen will be sent immediately from the operating room to Pathology for routine processing.

  • Lumpectomy
  • Mastectomy

Primary Outcome Measures :
  1. To quantify the degree of tumor-free margin achieved with image-guided vacuum assisted biopsy followed by ablation with radiofrequency ablation [ Time Frame: Post-surgical pathology review ]

Secondary Outcome Measures :
  1. The proportion of patients with viable tumor cells beyond the margin [ Time Frame: Post-surgical pathology review ]
