The impact of resection margins in the treatment of primary sarcomas of the breast. A clinicopathological study of 8 cases with review of literature.
We reviewed the clinical and pathological features of eight patients (seven females, one male), who underwent surgery for sarcomas of the breast, to evaluate the effect of the margins of resection and histological tumor type on survival. Patients with carcinosarcoma, cystosarcoma phyllodes or dermatofibrosarcoma protuberans were excluded. Tumor size ranged between 4.5 and 26 cm (median 12.8 cm); there were three grade 3, four grade 2 and one grade 1 lesions. Of the five patients treated by radical resection margins, two with large grade 3 sarcomas died of distant metastasis 3 and 10 months later. One patient out of the five radical resected patients developed a local recurrence 96 months later. The recurrence was resected radically, radiotherapy was administered, and the patient is still alive at 168 months. The remaining four radical resected patients are free of disease until now. One of three patients, treated by wide or marginal resection, received adjuvant radiotherapy. This patient developed local recurrence and solitary distant metastasis at 26 and 49 months, respectively, and died of multiple distant metastasis at 54 months. Regional axillary lymph node metastasis was not observed in five patients in whom lymph node dissection was performed, with a median of 14.2 dissected lymph nodes. Two of eight patients received preoperative chemo- or radiotherapy because of large tumor size; five of eight received postoperative radiotherapy. Local tumor control was achieved in six of eight patients. The median follow-up time was 53.9 months (3-168 months), of all survivors median 72.2 months. Recurrence and disease-free survival rates were analysed according to histologic grade, tumor size, stage, surgical and adjuvant treatment.
