Abstract:
:Sarcoma of the breast represents less than 1% of primary mammary malignancies; this study reports 25 such cases. The largest group had malignant fibrous histiocytoma (44%), followed by liposarcoma (24%) and fibrosarcoma (16%). Also represented were clear cell sarcoma, neurogenic sarcoma, leiomyosarcoma, and alveolar soft part sarcoma (4% each). Of 19 patients treated by wide local excision or simple mastectomy with or without adjuvant radiotherapy, 11 had local recurrence develop, of which one patient died and nine of the remaining ten had metastases develop. Of the remaining eight patients in this group with no local recurrence, only two had metastases develop. Of the six patients treated by radical or Patey mastectomy, none had local recurrence develop, but two died of metastases. No patient had metastases develop more than 5 years after diagnosis. Regional lymph node involvement with tumor was observed in only one patient (with malignant fibrous histiocytoma) despite regional lymphadenopathy in seven. The overall mortality at 5 years is 64% but does not increase thereafter. The authors' findings suggest that failure to establish local control is associated with a poor prognosis and that wide local excision or simple mastectomy does not provide sufficient clearance to be used as first-line treatment. Excision of the axillary lymphatics and adjuvant radiotherapy are unlikely to be beneficial.
