Description
Objectives To assess the ablative effectiveness, the oncological and cosmetic efficacy of image-guided percutaneous cryoablation in the treatment of single breast nodules with subclinical dimensions after identification with ultrasonography (US), mammography, magnetic resonance (MRI) and characterization by vacuum assisted biopsy. Materials Fifteen women with a mean age of 73±5 years (range 64–82 years) and lesion diameter of 8±4 mm were undergoing cryotherapy technology with a single probe under US-guidance associated with intra-procedural lymphnode mapping and excision of the sentinel node. All the patients underwent surgical resection (lumpectomy) from 30 to 45 days after the percutaneous ablation. Results The iceball size generated by the cryoprobe during the procedure at minus 40°C was 16×41 mm. In 14 of the 15 patients was observed a complete necrosis of the cryoablated lesion both in post-procedural MRI follow-up and anatomo-pathological evaluation after surgical resection. In one case there was a residual disease in post-procedural MRI and postoperative histological examination, probably justified by an incorrect positioning of the probe. Conclusion The percutaneous cryoablation as a “minimally invasive” technique can provide excellent oncological and cosmetic results on selected cases handled by experienced operators by using the tested devices.
