Background: Phyllodes tumors are rare distinctive fibro-epithelial tumors of the breast and their management continues to be questioned. Between 10% and 40% of phyllodes tumors have a tendency for LR and general dissemination. The aim of our study was to review the management of Phyllodes Tumour (PT) and to examine the determinants of local recurrence (LR).
Methods: A retrospective cohort study of female patients with histologically proven PT who presented to Ain Shams University Hospital (ASUH) between August 2014 and August 2018. Data collected from their files were analyzed to correlate LR after surgical intervention to demographic characteristics, tumour site, tumour size, tumour pathological grade, safety margin and type of performed surgery.
Results: Our study included 24 patients who presented to ASUH and were diagnosed to have PT, with follow up a mean of 30 months ±10. Only 6 patients (25%) demonstrated LR after the surgical intervention by a mean of 1.250 years ± 0.354 (range 1-1.5 years). In the recurrent group, the mean age was 39.333 (range 27-51) (P 0.636), the lesion size was between 5-15 cm (mean 11.667) (P 0.016), and safety margin was exceeding 10mm (P 0.422).
Conclusion: Benign and small PTs should be removed with safety margin rather than simple excision, and their malignant potential should be considered. Wider-scale studies are vital in understanding the recurrence behavior of this rare disease.
