Breast cancer outcomes after skin- and nipple-sparing mastectomy in BRCA pathogenic mutation carriers versus non-BRCA carriers.

Unlabelled: Our previous study on breast cancer BRCA carriers disclosed a high local recurrence (LR) rate in patients who underwent skin sparing (SSM) or nipple sparing mastectomy (NSM) without postoperative radiation therapy (RT), compared to breast conservation surgery or mastectomy with RT. The current study compares the LR rates in BRCA versus non BRCA carriers after SSM/NSM in relation the receipt of RT.

Deep Learning for Contrast Enhanced Mammography - A Systematic Review.

Background/aim: Contrast-enhanced mammography (CEM) is a relatively novel imaging technique that enables both anatomical and functional breast imaging, with improved diagnostic performance compared to standard 2D mammography. The aim of this study is to systematically review the literature on deep learning (DL) applications for CEM, exploring how these models can further enhance CEM diagnostic potential.

Methods: This systematic review was reported according to the PRISMA guidelines.

Evaluating ten years of breast cancer screening with contrast enhanced mammography in women with Intermediate-high risk.

Purpose: While mammography is considered the gold standard for screening women for breast cancer, its accuracy declines in women with dense breasts. The purpose of the study is to evaluate the diagnostic accuracy of contrast enhanced mammography (CEM) for detecting breast cancer in intermediate and high-risk women, including those with genetic predispositions, over a decade-long cohort at a tertiary center.

Methods: We retrospectively analyzed all CEM examinations performed for screening purposes at a tertiary center between 2012 and 2023.

Utility of Clinical-Pathological Parameters for Exclusion of BRCA1/2 Mutation Carriers as Candidates for Partial Breast Irradiation.

Purpose: Several international groups have published guidelines to identify low-risk breast cancer (BC) patients who are eligible for partial breast irradiation (PBI). These include the American Society for Radiation Oncology (ASTRO), the European Society for Radiotherapy and Oncology (ESTRO), and ESTRO subgroups such as the Intraoperative radiation (IORT) Task Force and Groupe Européen de Curiethérapie (GEC) -ESTRO. Only ASTRO guidelines recommend against the use of PBI in known carriers of germline pathogenic variants (PVs) in BRCA1/2.

Breast cancer diagnosed after age 70 years in Israeli BRCA1/BRCA2 pathogenic sequence variant carriers: a single institution experience.

Purpose: A semi-annual surveillance scheme from age 25 to 30 years is offered to BRCA1/BRCA2 pathogenic sequence variants (PSVs) carriers for early detection of breast cancer (BC). There is a paucity of data on the yield of adhering to this scheme beyond 70 years of age.

Relaxation-Diffusion T2-ADC Correlations in Breast Cancer Patients: A Spatiotemporally Encoded 3T MRI Assessment.

Quantitative correlations between T2 and ADC values were explored on cancerous breast lesions using spatiotemporally encoded (SPEN) MRI. To this end, T2 maps of patients were measured at more than one b-value, and ADC maps at several echo time values were recorded. SPEN delivered quality, artifact-free, TE-weighted DW images, from which T2-ADC correlations could be obtained despite the signal losses brought about by diffusion and relaxation.

'Earlier than Early' Detection of Breast Cancer in Israeli Mutation Carriers Applying AI-Based Analysis to Consecutive MRI Scans.

Female (=) pathogenic variants (PVs) carriers are at a substantially higher risk for developing breast cancer (BC) compared with the average risk population. Detection of BC at an early stage significantly improves prognosis. To facilitate early BC detection, a surveillance scheme is offered to PV carriers from age 25-30 years that includes annual MRI based breast imaging.

Divergence of mutational signatures in association with breast cancer subtype.

Abnormal molecular processes occurring throughout the genome leave distinct somatic mutational patterns termed mutational signatures. Exploring the associations between mutational signatures and clinicopathological features can unravel potential mechanisms driving tumorigenic processes. We analyzed whole genome sequencing (WGS) data of tumor and peripheral blood samples from 37 primary breast cancer (BC) patients receiving neoadjuvant chemotherapy.

Pregnancy Associated Breast Cancer Among Israeli BRCA1/BRCA2 Carriers in a High-Risk Clinic.

Rationale And Objectives: Female carriers of pathogenic sequence variants (PSVs) in the BRCA1 /BRCA2 (Breast Cancer gene - BRCA) genes are at a substantially high-risk for developing breast cancer (BC), hence are offered active surveillance scheme based on semiannual breast exam and imaging from age 25 years to facilitate BC early detection (mammography/breast ultrasound depending on the age, and MRI). However, there are not specific guidelines for screening in case of pregnancy or lactation. In the current study, we summarize the experience at the largest high-risk clinic in Israel.
