RATIONALE AND OBJECTIVES: Recent ICE3 trial of breast cryoablation for breast cancer demonstrated 98% success rate, similar to breast-conserving surgery. However, ICE3 and other published studies did not differentiate curative from palliative treatment nor define patient-specific treatment objectives. We sought to define treatment success of curative and palliative breast cryoablation for breast cancer in meeting procedure objectives and patient-specific treatment objectives.
MATERIALS AND METHODS: We conducted a retrospective analysis of breast cancer patients who underwent breast cryoablation during 2021-2024. Breast radiologists performed outpatient cryoablation using local anesthesia and argon gas cryoprobes under ultrasound or MRI guidance. Patient demographics, referral indications, tumor characteristics, procedure details, and imaging follow-up findings were analyzed. Cryoablation was categorized as curative or palliative. Treatment success was defined as achievement of both procedure and patient-specific treatment objectives.
RESULTS: Breast cryoablation was performed for 34 lesions in 29 patients with N0M0 (n = 25), N1M0 (n = 2), N2M0 (n = 1), and N0M1 (n = 1) disease. Most tumors were invasive ductal carcinoma (IDC), low to intermediate grade, estrogen receptor (ER) and progesterone receptor (PR) positive and HER2 negative (23 tumors, 68%). Tumor size ranged from 0.4-1.9 (median 0.8) cm for curative cryoablation and 0.6-6.0 (median 1.3) cm for palliative cryoablation. For 27 patients with follow-up imaging, ablation was curative in 14 patients, 14 tumors and palliative in 13 patients, 18 lesions. Imaging follow-up time ranged from 3 to 26 (median 16) months, > 12 months in 22 of 27 patients and 25 of 32 tumors. Complications were limited to 2 cases of skin frost injury, 1 mild and 1 moderate. Treatment success was achieved in 13 of 14 patients with curative and all 13 patients with palliative cryoablation.
CONCLUSION: Our study defines treatment success for curative and palliative breast cryoablation, demonstrates breast cryoablation achieves not only procedure (technical) but also patient-specific treatment objectives without significant complications, and may serve as guide for integrating breast cryoablation in the treatment of breast cancer patients.
