Cryoablation vs Lumpectomy in T1 Breast Cancers
COOL-IT: Cryoablation vs Lumpectomy in T1 Breast Cancers: A Randomized Controlled Trial With Safety Lead-in
Washington University School of Medicine
120 participants
Apr 3, 2024
INTERVENTIONAL
Conditions
Summary
This trial studies the efficacy and safety of cryoablation in patients with low risk, early stage breast cancer. Cryoablation is a method of killing a tumor by freezing it. The standard approach for patients with this kind of cancer is a lumpectomy. This study will review the safety of the cryoablation procedure initially, followed by comparing cryoablation to lumpectomy in order to see if the cryoablation results in better disease control, complication rates, and quality of life.
Eligibility
Inclusion Criteria6
- Diagnosis of invasive ductal carcinoma of the breast (ER , Her-2 negative) that is grade 1 or 2 with intraductal component \<25%. Must be T1N0M0 (2 cm or less).
- If DCIS is present in the biopsy specimen it should be \<25% of the tumor and should be contiguous with the IDC. (i.e. DCIS should not be a separate tumor from the IDC).
- Oncotyping will be performed on T1b+Allred\<6/8 and T1c tumors. Oncotype score in this subset of patients must be \<26 to be included in the trial.
- At least 50 years of age.
- Negative ipsilateral axillary assessment as determined either by (1) negative axillary ultrasound (2) negative sentinel lymph node biopsy or (3) negative percutaneous axillary node biopsy with no further clinical or imaging concern for nodal metastatic disease.
- Able to understand and willing to sign an IRB-approved written informed consent document.
Exclusion Criteria6
- Indication for neoadjuvant chemotherapy.
- Prior history of breast cancer.
- Breast augmentation.
- Allergy to local anesthetics.
- Pregnant or lactating. Women of childbearing potential must have a negative pregnancy test within 14 days of study entry.
- Tumoral involvement of skin or chest wall.
Interventions
The Endocare(TM) SlimLine (TM) Cryoprobe is a single use, disposable device designed for use with Endocare Cryocare Surgical Systems. Endocare cryoprobes are designed to deliver cold temperatures for cryoablation using high-pressure argon gas circulated through the cryoprobe, followed by active thawing using helium gas. The Cryocare CS Surgical System is intended for use in open, minimally invasive, or endoscopic surgical procedures in the areas of general surgery, urology, gynecology, oncology, neurology, dermatology, ENT, proctology, pulmonary surgery, and thoracic surgery. The system is designed to freeze/ablate tissue by the application of extreme cold temperatures.
Patients randomized to cryoablation who experience disease recurrence may undergo crossover to lumpectomy.
