Cryoablation as a Minimally Invasive Alternative to Surgery for Managing Ductal Carcinoma In Situ
(DCIS)
What this study is about
Cryoablation or tumor freezing is a percutaneous, office-based procedure that is emerging as a minimally invasive, cost-effective alternative to surgery that is currently being evaluated in clinical trials for the management of for early-stage invasive breast cancer.
View original scientific description
Cryoablation or tumor freezing is a percutaneous, office-based procedure that is emerging as a minimally invasive, cost-effective alternative to surgery that is currently being evaluated in clinical trials for the management of for early-stage invasive breast cancer. The investigator will also evaluate the potential of cryoablation as a minimally invasive alternative to surgery for small areas of DCIS by examining its ability to achieve complete ablation of DCIS within the targeted cryoablation zone of necrosis.
Interventions
PROCEDURE
Cryoablation
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 After the second freeze, the cryoprobe will be withdrawn from the breast and a bandage will be applied to the skin.
Primary outcome measures
Ability of cryoablation to achieve complete ablation of DCIS
Time frame: 6 months
Number of participants to achieve completeness of ablation by measuring the percentage of subjects with no residual DCIS or invasive cancer within the zero of necrosis assessed in the post-cryoablation core biopsy obtained 6 months post-cryoablation.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
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
Where
- Glendale, California

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
