Phyllodes Tumors

Abstract

The purpose of this study is to formulate guidelines for proper surgical management ofphyllodes tumours. It is a disease often misdiagnosed by the pathologist and undertreated by surgeons. We have retrospectively studied 12 patients with histologically proven cystosarcoma phyllodes (CSP). There were 4 benign and 8 malignant lesions, with an incidence of 33.33% vs 66.66% respectively. The treatment was surgical in all patients. The extent of surgery ranged from wide local excision to Modified Radical Mastectomy (MRM). One patient with malignant CSP developed lung metastases (12.5%) and three had recurrences (37.5%). The exact recurrence rate can't be calculated because 5 patients lost follow-up. The results of this study indicates that local excision is safe for benign CSP and all patients with malignant CSP should be treated by mastectomy since there is a high recurrence rate with local excision (37.5 %).
