Abstract

Purpose: Percutaneous removal of benign breast tumors using ultrasound-guided vacuum-assisted breast biopsy (VABB) has been recently regarded as a feasible and safe method without serious complications. The aim of this study was to evaluate the efficacy and safety of the VABB in the treatment of benign phyllodes tumors, and to identify whether or not surgical re-excision is necessary for benign phyllodes tumors diagnosed and excised by VABB.
Methods: From January 2003 to December 2011, a total of 6,923 VABB were performed in 5,434 patients. Out of 6,923 lesions, 53 were benign phyllodes tumors. Among these, 31 lesions, with a follow-up period of longer than 24 months, were enrolled in this study. Ultrasonography follow-up was performed at 3 to 6 month intervals in order to assess recurrence. The mean follow-up period was 75.9±13.5 months (range, 24-94 months).
Results: The mean patient age at presentation was 31.6±9.4 years. The mean size of the lesion was 1.60±0.88 cm. The majority of lesions, 74.2% (23 cases), were palpable, and 25.8% (8 cases) were non-palpable. Twenty-two lesions (71.0%) were classified as Breast Imaging Reporting and Data System category 3, and nine lesions (29.0%) were classified as category 4a, by ultrasonography. During the follow-up period, local recurrence developed in one lesion, making the local recurrence rate 3.2%.
Conclusion: If a benign phyllodes tumor is diagnosed, and sufficiently excised by VABB, observing the clinical course may be considered as an alternative to performing immediate wide local excision; this is the case despite the fact that it would need to be observed for a prolonged period of time.
