Cryoablation in breast tumours

Area of Science:

• Oncology
• Minimally Invasive Surgery
• Radiology

Background:

• Cryoablation is a percutaneous thermal ablation technique using extreme cold to destroy cells.
• It is an outpatient, image-guided procedure performed under local anesthesia with short recovery times.
• Cryoablation demonstrates good success rates for breast fibroadenomas.

Purpose of the Study:

• To describe the technique of percutaneous cryoablation for breast tumors.
• To review the indications for cryoablation in breast tumor treatment based on current literature.
• To evaluate the efficacy and safety of cryoablation for breast fibroadenomas and malignant tumors.

Main Methods:

• Literature review of studies on percutaneous cryoablation for breast tumors.
• Analysis of technique, indications, success rates, and safety profiles.
• Comparison with existing treatment modalities like lumpectomy.

Main Results:

• Cryoablation is effective for breast fibroadenomas.
• It is considered for malignant tumors when surgery is refused or contraindicated.
• Studies suggest cryoablation may be as effective and safe as lumpectomy for low-risk early-stage breast cancer.
• Regression of metastatic foci has been reported, potentially due to cryoablation-stimulated anti-tumor immune response.

Conclusions:

• Percutaneous cryoablation is a viable treatment option for breast fibroadenomas.
• It offers a minimally invasive alternative for select breast cancer patients.
• The potential for immune response stimulation warrants further investigation.
