The Usefulness of Ultrasound Surveillance for Axillary Recurrence in Women With Personal History of Breast Cancer

Research output: Contribution to journalArticlepeer-review

Abstract

Purpose: To evaluate the axillary recurrence rate and usefulness of axillary ultrasound (AUS) during supplementary whole-breast ultrasound (US) screening in women with a personal history of breast cancer (PHBC). Methods: A retrospective database search identified consecutive asymptomatic women who underwent postoperative supplemental whole-breast US screening, including that of the bilateral axillae, after negative findings on mammography between January and June 2017. Using the pathologic data or at least 1-year follow-up data as reference standards, the axillary recurrence rate, cancer detection rate (CDR), interval axillary recurrence rate per 1,000 screenings, sensitivity, specificity, and abnormal interpretation rate (AIR) were estimated. Results: From the data of 4,430 women (mean age, 55.0 ± 10.1 years) analyzed in this study, there were five axillary recurrence cases (1.1/1,000) in the median follow-up period of 57.2 months. AUS showed a CDR of 0.2 (1/4,430; 95% confidence interval [CI], 0.01–1.3) and an interval axillary recurrence rate of 0.9 (4/4,402; 95% CI, 0.2–2.3) per 1,000 examinations. The sensitivity and specificity were 20.0% (1/5; 95% CI, 0.5–71.6), and 99.4% (4,398/4,425; 95% CI, 99.1–99.6), respectively, while the AIR was 0.6% (28/4,430; 95% CI, 0.4–0.9%). Conclusion: In asymptomatic women with a PHBC and negative findings on mammography, axillary recurrence after breast cancer and axillary treatment was uncommon, and the supplemental AUS screening yielded 0.2 cancers per 1,000 examinations.
