Radiofrequency ablation of early breast cancer followed by delayed surgical resection

Radiofrequency ablation of early breast cancer followed by delayed surgical resection: A promising alternative to breast-conserving surgery. The Breast, Oct 2011, Vol. 20(5), p.431-436

Ohtani, S., et al.

To examine the radiofrequency ablation (RFA) reliability in early breast cancer, we performed RFA followed by delayed surgical resection on 41 patients with invasive or non-invasive breast carcinoma less than 2 cm. MRI scans were obtained before ablation and resection. Excised specimens were examined pathologically by haematoxylin-eosin and nicotinamide adenine dinucleotide-diaphorase staining. 40 patients completed 1 RFA session, which was sufficient to achieve complete tumour cell death. Overall complete ablation rate was 87.8% (36/41). There were no treatment-related complications other than that of a superficial burn in 1 case. After RFA, the tumour was no longer enhanced on MRI in 25/26 (96.2%) cases. Residual cancer, which was suspected on MRI in 1 case, was confirmed pathologically. MRI could be an applicable modality to evaluate therapeutic effect. RFA could be an alternate local treatment option to breast-conserving surgery for early breast cancer.
