Breast conservation surgery by round block mammoplasty

Abstract

BackgroundRound block mammoplasty (RBM) is a type of Oncoplastic procedure to facilitate breast conservation surgery for breast cancer. MethodsRetrospective study of 270 patients who underwent this surgery. The surgical and oncological outcomes of RBM were studied. ResultsThe median age was 61 years and median follow-up 39 months. Most cancers (59%) were screen-detected. The location of the cancer was commonly in the upper outer quadrant followed by upper inner quadrant (20%). The average tumor size was 18 mm and in 48% of patients the whole tumor size increased to 23.5 mm due to associated DCIS. The median specimen weight was 41 gm. Forty patients (14.8%) had positive margins. Postoperative complications were seen in 18 patients (6.6%). There were 4 local and 1 axillary recurrences, and 8 distant metastasis. Contralateral symmetrising surgery was required in 13 patients (4.8%). ConclusionRBM is a robust and easily adaptable technique which provides good exposure for a safe oncological excision. The surgical and oncological outcomes are good and contralateral symmetrising surgery is rarely required.
