RESUMO
BACKGROUND AND OBJECTIVES: The aim of this study was to document the clinical and pathological features of a single institutional series of Asian patients with phyllodes tumors, and to determine the prognosis, the adequate management and the predictive histological features. METHODS: The clinical data were retrospectively studied from the medical records and the pathological data from the Department of Pathology were utilized to identify 33 patients diagnosed with phyllodes tumors between 2003 and 2010. RESULTS: Eight patients had benign tumors, 13 borderline and 12 malignant. Nine patients (27 %) had recurrence. No patients classified as benign phyllodes tumors had recurrence, but those with malignant phyllodes tumors had a high recurrence rate (41 %). The 5-year disease-free survival was 59 %. The 5-year overall survival was 81 %. The width of surgical margin was not related to disease recurrence and stromal overgrowth was the only prognostic factor in terms of disease-free survival and overall survival. CONCLUSIONS: The phyllodes tumors of borderline and malignant classification in Asian patients had a high recurrence rate. Clinical and pathological factors, except for stromal overgrowth, cannot predict disease recurrence. Further molecular research is warranted.
