The Utility of ACR TI-RADS in Predicting False-Negative Fine Needle Aspiration for Thyroid Cancer.

BACKGROUND: Thyroid nodule fine needle aspiration (FNA) biopsies are associated with a low false-negative rate. There is limited data regarding the predictive value of American College of Radiology Thyroid Imaging Reporting and Data System for false-negative FNA. METHODS: This single-center retrospective study evaluated 119 patients who underwent thyroidectomy. The association of TR category, along with other clinical variables, with false-negative FNA was evaluated. RESULTS: The overall false-negative rate of FNA was 10.8% (n = 9). False-negative FNAs were associated with younger age (mean 42 years vs 50.6 years, P = .04), larger nodule size (mean 4.4 cm vs 3.2 cm, P = .03), and a lower TR category (median 3 v 4, P = .01). DISCUSSION: Lower TR category, younger age, and larger nodule size were associated with false-negative FNA of thyroid nodules. These findings should be taken into context when counseling patients with thyroid nodules who have a benign FNA.

Utility of short-interval follow-up mammography after a benign-concordant stereotactic breast biopsy result.

BACKGROUND: There is currently no clear consensus recommendation for the use of short-interval follow-up mammography after a benign-concordant breast biopsy (BCBB), and practice patterns vary widely. The objectives of this study were to evaluate whether a short-interval follow-up mammogram provided clinical utility after stereotactic BCBB and to examine the costs associated with this surveillance strategy. METHODS: A retrospective review of women who underwent a stereotactic breast biopsy yielding benign-concordant results between January 2005 and October 2014 was performed to evaluate findings on subsequent imaging, to calculate compliance with recommended short-interval imaging, and to examine whether subsequent imaging revealed an abnormality at the site of the initial stereotactic BCBB. A cost analysis was performed utilizing Medicare reimbursement rates to calculate projected and actual costs of short-interval follow-up imaging after stereotactic BCBB. RESULTS: Of the 470 stereotactic BCBB performed, a short-interval mammogram was completed in 207 (44.0%), 9 (4.3%) of which had suspicious mammographic findings at the initial biopsy site, and 6 subsequently underwent biopsy, with none resulting in malignant or high-risk pathology. The cost of short-interval mammographic follow-up (n = 207) was calculated at $28,541.16. CONCLUSIONS: This study provides evidence that 6-month follow-up mammography has low clinical utility and unnecessarily increases costs after stereotactic BCBB. A safe and more cost-effective strategy may be resumption of routine mammography at 12 months post-biopsy.
