Phyllodes tumors (PT) of the breast seem to get pre-operatively misdiagnosed as fibroadenomas resulting in inadequate resections and high local recurrence rates.


Data of 150 patients with PT of the breast managed from January, 2003 to February, 2013 were retrospectively analyzed. Statistical analysis performed using SPSS version 17 (Pearson Chi-square test and analysis of variance test for analysis).


The aim of this study is to compare clinico-pathological profile and recurrence rates in patients with benign (B), borderline malignant (BL) and malignant (M) PT.


In a total of 150 patients with PT (n = 77 B, n = 24 BL, n = 49 M), mean age was 36.92, 44.04 and 40.46 years respectively (P 0.015) and mean tumor size being 8.15 cm, 14.7 cm and 12.9 cm respectively (P 0.000). Pre-operatively cytology suggestive of PT in 24% patients with B PT and 63% in M PT; core tissue biopsy suggestive of PT in 85.4% patients with B PT and 100% in M PT. Recurrence seen in 34.7% out of which 32.7% were post-lumpectomy performed elsewhere. Majority of B PT had lumpectomy (49.3%)/wide local excision (WLE, 31.2%) compared with M PT where 55.1% had simple mastectomy (SM) due to large tumor size. Local recurrence was more in M PT (53%) compared with B PT (20%). We found recurrence rates in L (39.3%) compared with WLE (27.3%) and SM (33.9%) (P 0.049).


Larger tumor size, incomplete resection and M/BL histology predicted higher recurrence in PT. Core biopsy is much more accurate than fine needle cytology in the diagnosis.
