Genome-wide association studies (GWAS) have identified more than 170 breast cancer susceptibility loci. Here we hypothesize that some risk-associated variants might act in non-breast tissues, specifically adipose tissue and immune cells from blood and spleen. Using expression quantitative trait loci (eQTL) reported in these tissues, we identify 26 previously unreported, likely target genes of overall breast cancer risk variants, and 17 for estrogen receptor (ER)-negative breast cancer, several with a known immune function.

Reduction of False-Positive Markings on Mammograms: a Retrospective Comparison Study Using an Artificial Intelligence-Based CAD.

J Digit Imaging 2019 Apr 8. Epub 2019 Apr 8.

Voxel Imaging, Inc., 2711 N. Sepulveda Blvd., #284, Manhattan Beach, CA, 90266, USA.

The aim was to determine whether an artificial intelligence (AI)-based, computer-aided detection (CAD) software can be used to reduce false positive per image (FPPI) on mammograms as compared to an FDA-approved conventional CAD. A retrospective study was performed on a set of 250 full-field digital mammograms between January 1, 2013, and March 31, 2013, and the number of marked regions of interest of two different systems was compared for sensitivity and specificity in cancer detection. The count of false-positive marks per image (FPPI) of the two systems was also evaluated as well as the number of cases that were completely mark-free. Read More

Diagn Interv Imaging 2019 Apr 5. Epub 2019 Apr 5.

"Diagnostic Mammography" Medical Diagnostic Imaging Unit, Kifisias Avenue 362, Chalandri, 15233 Athens, Greece. Electronic address:

Three-dimensional automated breast ultrasound system (3D ABUS) is an innovation in breast ultrasound that has been developed to uncouple detection from image acquisition and to address the limitations of handheld ultrasound (HHUS). 3D ABUS provides a large field of view using high frequency transducers, producing high-resolution images and covering a large portion of the breast with one sweep. As more data become available on breast density and the impact of supplemental screening, 3D ABUS has gained wider acceptance as an adjunct tool to mammography. Read More

Angiomammography: A review of current evidences.

Diagn Interv Imaging 2019 Apr 5. Epub 2019 Apr 5.

Department of Diagnostic and Interventional Radiology, Lausanne University Hospital and University of Lausanne, 1011 Lausanne, Switzerland.

Although mammography is currently the imaging technique of choice for screening and diagnosis, it has some limitations, especially in patients with high-density breasts. The evolution from film screen to full-field digital mammography has recently led to the development of new imaging techniques, which are less expensive and widely available. Contrast-enhanced spectral mammography (CESM) is one of them, coupling X-ray breast imaging to the intravenous administration of an iodinated contrast material. Read More

Screening for distant metastases in patients with ipsilateral breast tumor recurrence: the impact of different imaging modalities on distant recurrence-free interval.

Breast Cancer Res Treat 2019 Apr 6. Epub 2019 Apr 6.

Department of Surgery, Catharina Hospital, Michelangelolaan 2, 5623 EJ, Eindhoven, The Netherlands.

Purpose: In patients with ipsilateral breast tumor recurrence (IBTR), the detection of distant disease determines whether the intention of the treatment is curative or palliative. Therefore, adequate preoperative staging is imperative for optimal treatment planning. The aim of this study is to evaluate the impact of conventional imaging techniques, including chest X-ray and/or CT thorax-(abdomen), liver ultrasonography(US), and skeletal scintigraphy, on the distant recurrence-free interval (DRFI) in patients with IBTR, and to compare conventional imaging with F-FDG PET-CT or no imaging at all.

Tissue Cell 2019 Apr 5;57:8-14. Epub 2019 Feb 5.

Arya Wellness Center, Guwahati 781032, Assam, India. Electronic address:

Fine needle aspiration cytology (FNAC) entails using a narrow gauge (25-22 G) needle to collect a sample of a lesion for microscopic examination. It allows a minimally invasive, rapid diagnosis of tissue but does not preserve its histological architecture. FNAC is commonly used for diagnosis of breast cancer, with traditional practice being based on the subjective visual assessment of the breast cytopathology cell samples under a microscope to evaluate the state of various cytological features.
