Imaging biomarkers of breast cancers originating from the major lactiferous ducts: Ductal adenocarcinoma of the breast, DAB.

Eur J Radiol 2022 Jun 4;154:110394. Epub 2022 Jun 4.

School of Oral Hygiene, College of Oral Medicine, Taipei Medical University, Wuxing Street, Taipei 110, Taiwan.

Purpose: As we have previously demonstrated, breast cancers originating in the major lactiferous ducts and propagating through the process of neoductgenesis are a distinct subtype of invasive breast cancers, although by current practice they are placed within the group termed ductal carcinoma in situ (DCIS) and are consequently underdiagnosed and undertreated. Imaging biomarkers provide a reliable indication of the site of origin of this breast cancer subtype (Ductal Adenocarcinoma of the breast, DAB) and have excellent concordance with long-term patient outcome. In the present paper, the imaging biomarkers of DAB are described in detail to encourage and facilitate its recognition as a distinct, invasive breast cancer subtype. Read More

Diagnostic Challenge of Invasive Lobular Carcinoma of the Breast: What Is the News? Breast Magnetic Resonance Imaging and Emerging Role of Contrast-Enhanced Spectral Mammography.

J Pers Med 2022 May 25;12(6). Epub 2022 May 25.

Radiology Unit, Mater Olbia Hospital (Qatar Foundation Endowment and Policlinico Universitario Agostino Gemelli IRCCS Foundation), Strada Statale 125 Orientale Sarda, 07026 Olbia, Italy.

Invasive lobular carcinoma is the second most common histologic form of breast cancer, representing 5% to 15% of all invasive breast cancers. Due to an insidious proliferative pattern, invasive lobular carcinoma remains clinically and radiologically elusive in many cases. Breast magnetic resonance imaging (MR) is considered the most accurate imaging modality in detecting and staging invasive lobular carcinoma and it is strongly recommended in pre-operative planning for all ILC.

Axillary Lymph Node Swelling After COVID-19 Booster Vaccination: Japanese Case Report and Literature Review.

In Vivo 2022 Jul-Aug;36(4):1977-1981

Department of Surgery, Nagoya Tokushukai General Hospital, Kasugai, Japan.

Background/aim: COVID-19 has been a global pandemic for more than 2 years, and vaccination against COVID-19 using an mRNA vaccine is widespread. The COVID-19 vaccination can cause specific side-effects, such as axillary lymph node swelling; therefore, breast oncologists should pay attention to such occurrences. Initially, only two COVID-19 vaccinations were planned; however, in some countries third or fourth vaccines have been administered. Read More

Management of Non-Mass Enhancement at Breast Magnetic Resonance in Screening Settings Referred for Magnetic Resonance-Guided Biopsy.

Breast Cancer (Auckl) 2022 16;16:11782234221095897. Epub 2022 May 16.

Department of Radiology, Femme-Laboratório da Mulher, São Paulo, Brazil.

Rationale And Objectives: According to the Breast Imaging and Reporting Data System (BI-RADS), one of the main limitations of MRI is diagnosing the non-mass enhancement (NME). The NME lesion is challenging since it is unique to the MRI lexicon. This study aims to report our experience with NME lesions diagnosed by MRI referred for MRI-guided biopsies and discuss the management and follow-up of these lesions. Read More

Assessing the influence of the menstrual cycle on APT CEST-MRI in the human breast.

Magn Reson Imaging 2022 09 10;91:24-31. Epub 2022 May 10.

German Cancer Research Center, Department of Radiology, Im Neuenheimer Feld 280, 69120 Heidelberg, Germany. Electronic address:

Purpose: In fibroglandular breast tissue, conventional dynamic contrast-enhanced MR-mammography is known to be affected by water content changes during the menstrual cycle. Likewise, amide proton transfer (APT) chemical exchange saturation transfer (CEST)-MRI might be inherently prone to the menstrual cycle, as CEST signals are indirectly detected via the water signal. The purpose of this study was to investigate the influence of the menstrual cycle on APT CEST-MRI in fibroglandular breast tissue. Read More

Eur J Breast Health 2022 Apr 1;18(2):199-202. Epub 2022 Apr 1.

Department of Radiology, Trakya University Faculty of Medicine, Edirne, Turkey.

Breast cancer is a rare entity in men, accounting for less than 1% of all breast cancers. Contralateral breast cancer diagnosed within 12 months of the prior breast cancer is known as bilateral synchronous breast cancer. Bilateral, synchronous male breast cancer is extremely rare and consequently there are few publications describing imaging findings of synchronous bilateral male breast cancer. Read More

Breast Density and Estradiol Are Major Determinants for Soluble TNF-TNF-R Proteins in Human Breast Tissue.

Front Immunol 2022 30;13:850240. Epub 2022 Mar 30.

Department of Oncology, Linköping University, Linköping, Sweden.

High mammographic density and exposure to sex steroids are independent risk factors for breast cancer by yet unknown mechanisms. Inflammation is one hallmark of cancer and the tumor necrosis factor family of proteins (TNFSFs) and receptors (TNFRSFs) are key determinants of tissue inflammation. The relationship between TNFSFs/TNFRSFs and breast tissue density or local breast estradiol levels is unknown. Read More

The ins and outs of male breast and anterior chest wall lesions from childhood to adulthood.

Clin Radiol 2022 Jul 29;77(7):503-513. Epub 2022 Mar 29.

Department of Radiology, Princess Margaret Hospital, 2-10 Princess Margaret Hospital Road, Lai Chi Kok, Kowloon, Hong Kong.

Physiological and pathological processes arising from the breast and anterior chest wall may share similar clinical presentations because of the small volume of male breasts. Therefore, imaging is frequently required to localise and characterise the lesion and guide biopsy when radiological findings are equivocal or suspicious. Mammography or digital breast tomosynthesis (DBT) and ultrasound are the mainstays of breast imaging work-up. Read More

Cairo University, Computers and Artificial Intelligence, Computer Science Department, Cairo, 12613, Egypt.

Contrast-enhanced spectral mammography (CESM) is a relatively recent imaging modality with increased diagnostic accuracy compared to digital mammography (DM). New deep learning (DL) models were developed that have accuracies equal to that of an average radiologist. However, most studies trained the DL models on DM images as no datasets exist for CESM images. Read More
