Traitement conservateur des cancers du sein : zonectomie vs oncoplastie. Étude prospective à propos de 99 patientes

The integration of oncoplastic techniques with a concomitant contralateral symmetrization procedure is a novel surgical approach that allows wide excisions and prevents breast deformities.

Aim of the study. – This prospective study was undertaken to compare the accuracy of breast resection, between standard narrow lumpectomy and oncoplastic surgery.

Patients and methods. – Ninety-nine consecutive women undergoing breast cancer resection were enrolled in a prospective study comparing oncoplastic surgery (42 women) and standard lumpectomy (57 women). The size of the glandular resection, the width of the nearest margins, the ratio of clear margins and the need for further surgery were recorded.

Results. – The oncoplastic approach resulted in significantly greater glandular resection and wider free histological margins than did standard lumpectomy. The need for re-exicsional surgery was significantly lower in the oncoplastic group than in the lumpectomy group. Furthermore, a trend towards fewer secondary mastectomies was seen for the oncoplastic approach versus standard lumpectomy.

Conclusions. – The use of oncoplastic techniques and concomitant symmetrization of the contralateral breast allows extensive resections for conservative treatment of breast carcinoma achieves accurate tumour resection and reduces the need for further surgery.
