Purpose The aim of this study is to compare some biological and radiological features between IBCs and SDBCs and between the different subtypes of IBCs.
Read more Methods and materials A retrospective single-center cohort study was conducted among women aged 45–74 years who participated to a BC regional mammographic screening program at the Breast Unit (BU) of Rimini Hospital (Italy) with EUSOMA accreditation between January 2018 and July 2023: in this period, 169.024 screening mammograms were performed. The program was based on the European Guidelines for Quality Assurance in Mammographic Screening [1]. Women aged 45–49 and those aged 50–74 were followed up through digital mammography every 1 year and every...
Read more Results One hundred and fifteen women with IBCs (mean age 59.6 years) and two hundred and twenty-nine SDBCs (mean age 59.8 years) were included in this study. TIBCs [54 (47%)] was the most common subtype of IBCs, followed by MS [30 (26%)], FN [20 (17.4%)] and OC [11 (9.6%)]. The radiological classification of IBCs is shown in [table]1. A total of 52 IBCs (45%) developed during the second post-screening year (> 12 months), especially TIBCs [26 (48.1%)]. Other subtypes were distributed...
Read more Conclusion The present study highlighted substantial radiological and prognostic differences between IBCs and SDBCs. From a radiological perspective, patients with IBCs were more likely to show a high breast density compared to SDBCs. This finding is in line with current literature [5-7]. First, it has long been known that higher mammographic density (MD) is a strong independent predictor of BC. On one hand, higher prevalence of high breast density among IBCs than SDBCs observed in our study may explain the “masking...
