Abstract

BACKGROUND: Cystosarcoma phyllodes are relativly rare neoplasms of the breast and have an unpredictable clinical behavior. This study is to determine whether histological features correlate with clinical behavior, and which operation method affect recurrence.
METHODS
This study reviewed the histological features and clinical outcomes in 12 patients with phyllode tumors of the breast diagnosed at Chungnam University Hospital from 1989 to 1998.
RESULTS
The pathological results revealed benign forms were in 8 cases and malignant forms in 4 casese. As to the nature of the growth, the tumors in 10 cases grew rapidly 10 cases were rapid in nature, but two malignant tumors not. One of the 4 malignant tumors was high grade, the others were borderline. Eight (8) patients were had been treated conservatively (7 cases, wide tumor excision; 1 case, excisional biopsy), and 4 cases patients underwent radical operation (2 cases, modified radical mastectomy; other 2 cases, simple mastectomy). Only one patient with borderline malignancy, who underwent modified radical mastectomy, experienced recurrence.
CONCLUSIONS
Tumor growth & histological features do not correlate with recurrence, and wide resection should to be primary treatement and axillary dissection is not worthwhile.
