Breast deformity, its correction, and assessment of breast conserving surgery

Abstract

A combination of quadrantectomy, axillary dissection, and radiotherapy (QUART) is the regimen most favored by Japanese surgeons among a variety of breast conserving therapies currently available against breast cancer. Unfortunately, extensive resections such as quadrantectomy often give poor local cosmetic results in patients with small breasts. With the aim of improving the cosmetic aspect after an extensive resection, immediate transposition of the latissimus dorsi muscle (LDM) was carried out in breast conserving surgery. To date, twenty-one patients have been entered in this study. Post-quadrantectomy breast deformity was not corrected in six patients including one with bilateral breast cancers, but was corrected by transposition of a part of LDM in 14 other patients. In the last patient, who also had bilateral breast cancers, the right breast was treated by QUART and the left breast by subcutaneous mastectomy followed by transposition of LDM. The cosmetic outcome for these patients was assessed both subjectively and objectively; the objective assessment used a Moire topography camera. The postoperative appearance and topography revealed a satisfactory symmetry of breasts in the transposed patients, especially those with small breasts, when compared with non-transposed patients. It may be concluded that the transposition of LDM is useful in preventing breast deformity following an extensive resection in breast conserving surgery.
