Recurrence Rates and Characteristics of Phyllodes Tumors Diagnosed by Ultrasound-guided Vacuum-assisted Breast Biopsy (VABB)

Recently, the development of ultrasonography (US)-guided vacuum-assisted breast biopsy (VABB) has enabled the excision of benign breast tumors with normal surrounding breast tissues; thus, complete excision is possible without residual tumor tissue. We sought to identify the clinicopathological char...

Description
Summary:Recently, the development of ultrasonography (US)-guided vacuum-assisted breast biopsy (VABB) has enabled the excision of benign breast tumors with normal surrounding breast tissues; thus, complete excision is possible without residual tumor tissue. We sought to identify the clinicopathological characteristics and recurrence rates of benign phyllodes tumors diagnosed by US-guided VABB. Data from 11,221 US-guided VABBs performed at the Gangnam Cha Medical Center over 12 years were analyzed. Eighty-three lesions were diagnosed as benign phyllodes tumors; 67 with >24 months of follow-up data were investigated. All lesions were excised using an 8-gauge probe without residual tissue; patients underwent follow-up US every 3-6 months. Five patients (7.46%) experienced local recurrence during a mean follow-up period of 27.8 months; no distant metastases occurred. The mean tumor size was 3.0 cm in the recurrence group and 1.87 cm in the non-recurrence group (p=0.05). Benign phyllodes tumors excised and diagnosed using VABB showed a low recurrence rate during the follow-up period; thus, these tumors, particularly those
