  • Objective: The author has already published the experimental results around the employment of the thermal ablation with radiofrequency of the carcinoma and the fibroadenoma. The thermal ablation produces an effectiveness necrosis of the lesions for which the author has experimented the association of the breast lumpectomy with the thermal ablation of the borders of the residual breach with the purpose to reduce the risk of local recidivist and to allow a surgical treatment more preservative and aesthetical.

    Methods: 10 women of inclusive age have been enlisted between 18 and 75 years, with DCIS, inferior diameter to 2 cm and situated to at least 1 cm from the cutaneous plan and from the thoracic plan, not submitted in primary chemotherapy. The patients have been submitted to quadrantectomy and during the intervention in the residual surgical breach a special needle has been installed and has been performed the radiofrequency of margin some residual surgical breach. . They have been studied by the point of view istopatological the prepared surgical.

    Results: In 4 cases the margins were close but the patients don’t submitted to ulterior removal. Never developed relapse: Complication is not recorded.

    Conclusions: The thermal ablation increases the radical treatment of the lumpectomy that guarantees a mile resulted aesthetical in comparison to the quadrantectomy but introduces insufficient borders in the 40% of the T1s < 2 cm with recidivists in the native center of the tumor in the 70-90% of the cases. The preliminary results seem to point out that the RFA lumpectomy can be proposed in alternative to the quadrantectomy in the carcinoma of diameter up to 2.
