Abstract

To investigate the role of ultrasound (US) screening as an adjunct to annual mammography (M) in breast cancer detection in women with a history of lobular neoplasia (LN) diagnosed following core needle or excisional biopsy. A retrospective review of our database was performed between 11/2006 and 11/2011 to identify patients diagnosed with LN, and underwent annual screening. Patients with a lifetime risk >20% per risk modeling were excluded. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and cancer detection rate (CDR) of each screening test were identified. Cancer type and detection modality were recorded. A total of 100 patients who had M and/or US screening were included. Mean patient age was 54.7 years (range 33-83). All 100 patients underwent a mean of 3.9 rounds of screening M and 93 (93%) received US screening (mean 3.3 rounds). Of 93 patients who received both M and US screening, 12 (13%) were diagnosed with breast cancer. Mammographic CDR was 4%. Incremental US CDR was 6.5%. The sensitivity, specificity, and NPV for M screening alone was 33% (10%, 65%), 77% (67%, 85%), and 89% (80%, 95%), respectively. US and mammography screening had a combined sensitivity: 83% (52%, 98%), Specificity: 72% (62%, 81%), NPV: 97% (89%, 100%). Supplemental US screening resulted in a significant increase in sensitivity, yielding 6.5% incremental CDR in this high-risk patient subgroup that does not fulfill ACS high-risk MRI screening criteria.
