abstract
PURPOSE: To determine the effect of subspecialty review of breast imaging on patients without a diagnosis of breast cancer who self-referred for a second opinion. METHODS: Institutional review board-approved retrospective review was performed of 415 breast imaging studies submitted to our cancer center for second-opinion review by 245 patients in 2014, excluding cases without follow-up or change in original BI-RADS 0 assessment. One hundred forty-seven patients with 176 lesions were included. Original and second-opinion interpretations and recommendations were compared with histopathology or follow-up imaging. RESULTS: Ninety-six of 176 (55%) lesions were reported as suspicious in the original interpretation. Second-opinion review was discordant with the original interpretation in 82 of 176 (47%) lesions. Second-opinion review downgraded 24 of 96 (25%) lesions originally reported as suspicious to benign or probably benign, averting biopsy of these lesions. Second-opinion review upgraded 31 of 80 (39%) lesions originally reported as benign or probably benign to suspicious. A total of 87 lesions were biopsied yielding malignancy in 23 (26%) biopsies. Twenty-eight of 87 (32%) biopsies performed were recommended after second-opinion review, with 8 of 28 (29%) of these biopsies yielding cancer. Eight of 23 (35%) cancers detected represented malignancy not initially detected in the original interpretation. CONCLUSION: Second-opinion review is valuable in patients pursuing a breast imaging specialist's opinion, even before they are diagnosed with breast cancer. Second-opinion review disagreed with the original interpretation for 47% of lesions, averted 25% of originally recommended biopsies, and detected cancer in 29% of additional biopsies recommended. Thirty-five percent of cancers diagnosed after second-opinion review were not initially detected in the original interpretation.
