ABSTRACT
PURPOSE: Breast arterial calcifications (BAC) are incidentally observed on mammograms, yet their implications remain unclear. We investigated lifestyle, reproductive, and cardiovascular determinants of BAC in women undergoing mammography screening. Further, we investigated the relationship between BAC, coronary arterial calcifications (CAC) and estimated 10-year atherosclerotic cardiovascular (ASCVD) risk. METHODS: In this cross-sectional study, we obtained reproductive history and CVD risk factors from 215 women aged 18 or older who underwent mammography and cardiac computed tomographic angiography (CCTA) within a 2-year period between 2007 and 2017 at hospital. BAC was categorized as binary (present/absent) and semi-quantitatively (mild, moderate, severe). CAC was determined using the Agatston method and recorded as binary (present/absent). Adjusted odds ratios (ORs) and 95 % confidence intervals (CIs) were calculated, accounting for age as a confounding factor. ASCVD risk over a 10-year period was calculated using the Pooled Cohort Risk Equations. RESULTS: Older age, systolic and diastolic blood pressures, higher parity, and younger age at first birth (≤28 years) were significantly associated with greater odds of BAC. Women with both BAC and CAC had the highest estimated 10-year risk of ASCVD (13.30 %). Those with only BAC (8.80 %), only CAC (5.80 %), and no BAC or CAC (4.40 %) had lower estimated 10-year risks of ASCVD. No association was detected between presence of BAC and CAC. CONCLUSIONS: These findings support the hypothesis that BAC on a screening mammogram may help to identify women at potentially increased risk of future cardiovascular disease without additional cost and radiation exposure.

OBJECTIVE: Three-dimensional bioabsorbable tissue marker (BTM) placement during breast surgery is performed for the purpose of improved surgical cavity delineation for radiotherapy and improved cosmetic outcome. The purpose of this study is to evaluate the postsurgical imaging findings of BTM. METHODS: This Institutional Review Board-approved retrospective review included all patients implanted with BTM at breast surgery from January 2017 to September 2018. Demographics, tumor characteristics, imaging, and histologic findings were evaluated. Medical records were reviewed during a three-year period to evaluate for tumor recurrence. RESULTS: Ninety-seven patients had BTM implanted, of which 76 patients had imaging follow-up of at least 1 year. Of the 76 patients who had mammographic follow-up, 3 (3.9%) developed suspicious microcalcifications requiring biopsy, yielding ductal carcinoma in-situ in 2 patients and benign calcifications in 1 patient. Of 61 patients who had sonographic follow-up, 44 (72.1%) patients had complex fluid collections containing avascular, heterogeneously hyperechoic solid components, which remained stable or decreased in size over time; no recurrent tumors were found in this group. One patient (1.6%) had a vascular solid mass, which yielded recurrent papilloma. Four (6.6%) patients developed irregular hypoechoic masses at the surgical site, one of which corresponded with a developing asymmetry mammographically; biopsy yielded fibromatosis. Tissue sampling of the remaining three cases yielded invasive ductal carcinoma, fat necrosis, and radiation changes, respectively. CONCLUSION: Accurate identification of the expected postoperative imaging appearance of BTM may prevent unnecessary biopsy. Suspicious findings necessitating biopsy are pleomorphic calcifications, developing asymmetry and vascular and irregular hypoechoic masses.
