MRI-guided 9-gauge vacuum-assisted breast biopsy: initial clinical experience. Academic Article uri icon

Overview

abstract

  • OBJECTIVE: The objective of this study was to evaluate our initial clinical experience with MRI-guided vacuum-assisted breast biopsy as an alternative to surgical excision. MATERIALS AND METHODS: A retrospective review revealed 112 consecutive nonpalpable, mammographically occult MRI-detected breast lesions scheduled for MRI-guided vacuum-assisted biopsy. Biopsy was performed with a 9-gauge vacuum-assisted biopsy probe (Suros Surgical Systems) followed by clip placement (Artemis Medical). Medical records and histologic findings were reviewed. RESULTS: Among 112 lesions, biopsy was cancelled because of nonvisualization of the lesion in 14 (12%). Of the remaining 98 lesions, tissue was successfully acquired in 95 (97%). The median number of specimens obtained was 12 (range, 6-20). The median time to perform MRI-guided biopsy was 33 min for one lesion and 56 min for two lesions. Histology in 95 lesions was benign and concordant in 52 (55%), cancer in 24 (25%), high-risk in 10 (11%), and discordant in nine (9%). MRI-guided biopsy histologies in 24 cancers were ductal carcinoma in situ in 13 (54%) and infiltrating carcinoma in 11 (46%). Seven additional cancers were found at surgery in four discordant lesions and in three high-risk lesions. The clip successfully deployed in 86 (95%) of 91 lesions. Six complications (three hematomas, two instances in which the biopsy probe pierced the skin on the far side of the breast, and one vasovagal reaction) resolved without sequelae. CONCLUSION: MRI-guided vacuum-assisted biopsy is a fast and safe alternative to surgical biopsy for MRI-detected breast lesions. Imaging-histologic correlation is necessary to ensure lesion sampling.
