Ultrasound-guided vacuum-assisted excisional biopsy to treat benign phyllodes tumors

Abstract

PurposeTo evaluate the value of ultrasound (US)-guided vacuum-assisted excisional biopsy (VAB) in treating benign phyllodes tumors (PTs) of the breasts and to investigate the lesion characteristics that could affect the local recurrence rate. Patient and methodsFrom December 2008 to February 2018, 93 patients with PTs diagnosed on histology underwent US-guided, 7-gauge VAB. The recurrence rate of benign PT and complications of VAB were evaluated on follow-up US every three to six months. The lesion characteristics were analyzed to identify the factors affecting the recurrence rate. ResultsOf the 87 patients, local recurrence was found in 15 patients (17%) in a mean follow-up period of 35.8 months, and the rate of complete excision was 82.8% (72/87). PTs with a largest diameter less than 3.3 cm had a significantly lower recurrence rate than PTs with a largest diameter larger than 3.3 cm (P < 0.05). ConclusionsIn conclusion, US-guided VAB is an effective method to treat benign PT, especially in lesions with a diameter less than 3.3 cm.
