Objective
To determine the utility of short-interval follow-up after benign concordant MRI-guided breast biopsy.
Materials and methods
Institutional review board approved, retrospective review of consecutive biopsies performed over 3 years (2007–10) yielded 170 women with 188 lesions that were considered benign concordant. Indication for original study, biopsy results, follow-up recommendations, compliance and outcomes of subsequent MRI and mammography examinations were reviewed.
Results
The most common indication for breast MRI was high-risk screening 119/170 (70 %). Overall, 59 % of lesions (113/188) had follow-up MRI. Of those lesions (n = 113), 43 % (49/113) presented within 7 months, 26 % (29/113) presented within 8–13 months, 11.5 % (13/113) presented within 14–22 months, and 19 % (22/113) presented after 23 months. At initial follow-up, 37 % of lesions were stable and 61 % were decreased in size. Three lesions were recommended for excision based on follow-up imaging with one malignancy diagnosed 2 years following biopsy. One additional patient had MRI-detected bilateral cancers remote from the biopsy site 3 years after biopsy.
Conclusion
Overall cancer yield of lesions with follow-up MRI was 0.9 % (1/113); no cancers were detected at 6 months. Our data suggests that 6-month follow-up may not be required and that annual screening MRI would be acceptable to maintain a reasonable cancer detection rate.
Key Points
• Follow-up recommendations after benign concordant MRI-guided breast biopsy remain controversial.
• Cancer detection rate was 0.9 % overall with no cancers detected at 6 months.
• Short-interval follow-up after benign concordant MRI-guided breast biopsy may not be necessary.
