Oncologic and cosmetic outcome in patients with breast cancer treated with wide excision, transposition of adipose tissue with latissimus dorsi muscle, and axillary dissection followed by radiotherapy.

We evaluated the oncologic and cosmetic outcome in patients with breast cancer treated with wide excision, transposition of adipose tissue with latissimus dorsi muscle (LDM), and axillary dissection followed by radiotherapy. In this study, a wide excision of breast tissue was performed to obtain tumor-free margins. The subsequent breast deformity was not corrected in six patients in the early phase of the study (Group 1), and in 16 patients in the late phase (Group 2) in which the breast deformity was not remarkable at the time of operation. Breast deformity was corrected by transposing adipose tissue with LDM on a vascular pedicle in the remaining 51 patients (Group 3). Five year survival was 100%. Two patients developed distant metastases. None were found to have local recurrence. Fifty percent of the Group 1 patients, 69% of the Group 2 patients, and 67% of the Group 3 patients had an excellent or good cosmetic result. However, when the cosmetic results were evaluated in patients who underwent transposition and had small breasts, the results were excellent or good in 76%, compared to 38% in the patients who had reconstructions who had large breasts. The difference was statistically significant (p = 0.0309). Therefore, it was confirmed that wide excision and axillary dissection followed by breast radiation could provide adequate local control, but frequently resulted in breast deformity. However, transposition of adipose tissue may be useful to correct the breast deformity, especially in women with small breasts.
