Description
Inclusion Criteria:
- DCIS spanning 2 cm or less based on its radiographic appearance by mammography and/or breast contrast-enhanced MRI
- Diagnosis of DCIS by minimally invasive needle biopsy
- No prior history of DCIS or invasive breast cancer in the same breast
- No history of surgical biopsy and/or lumpectomy for diagnosis/treatment in the same breast
- Adequate breast volume and skin clearance to permit cryoablation as assessed by Dr. Holmes. This excludes male and females with breasts too small to allow safe cryoablation
- Non-pregnant, non-lactating, and no history of pregnancy within the preceding 6 months
- No history of breast radiation in the same breast

Other: Cryoablation
Phase I, single-arm study to evaluate the ability of cryoablation to achieve complete ablation of DCIS in the cryoablation zone of necrosis as a potential alternative to surgery.
|
The cryoprobe tip will be inserted into the breast and directed under ultrasound guidance to the location where the ultrasound visible marker is located.
Next, the cryoprobe will be used to freeze a 4 X 3 X 3 cm diameter area of DCIS using two separate 10-minute freeze cycles separated by a single 10-minute thaw cycle.
The cryoprobe will remain in place the entire time.
After the second freeze, the cryoprobe will be withdrawn from the breast and a bandage will be applied to the skin.
