Phylloides tumor of the breast: a report of 14 cases

Abstract

The objective of this retrospective study is to determine the role of radiation therapy in the management of benign phylloides tumors. Fourteen patients with a diagnosis of benign phylloides tumor (PT) and registered at the Princess Margaret Hospital are included in the study. Definitive surgery consisted of either lumpectomy in seven patients or mastectomy in the other seven patients. One patient died of her disease, and the remaining patients had no evidence of disease at last follow-up (median 38.4 months). Among these 13 patients, 4 had at least one recurrence and the recurrence rate was higher for the group who underwent lumpectomy (43% compared with 28%). One patient was treated by lumpectomy and adjuvant radiation therapy, and had no subsequent recurrence (follow-up time 35.5 months). The role for radiation therapy in the management of this disease remains unclear.
