Uptake of cancer risk management strategies among women who undergo cascade genetic testing for breast cancer susceptibility genes.

Cancer 2021 Jun 22. Epub 2021 Jun 22.

Department of Behavioral Science, The University of Texas MD Anderson Cancer Center, Houston, Texas.

Background: Uptake of cancer risk management based on inherited predispositions, which encompasses bilateral mastectomy (BLM), bilateral salpingo-oophorectomy (BSO), and intensified screening, is the primary motivation for cascade testing for hereditary breast and ovarian cancer (HBOC). However, long-term outcome data for cascade testers are lacking.

Methods: Medical records were abstracted for all unaffected women with pathogenic variants in HBOC genes from 2 cancer hospitals (2013-2019) with at least 1 year of follow-up to compare the uptake of surgery and screening between cascade and noncascade testers. Read More

Inflammatory Myofibroblastoma of the Breast: A Case Report.

Front Oncol 2021 1;11:646336. Epub 2021 Jun 1.

Department of Radiology, The Third Affiliated Hospital of Zunyi Medical University, The First People's Hospital of Zunyi, Zunyi, China.

Inflammatory myofibroblastic tumor (IMT) is a rare tumor with low-grade malignant risk mainly occurring in soft tissues and lungs, and it is extremely rare in the breast. Meanwhile, imaging findings of the tumor often present with non-specific features that lead to misdiagnosis and delayed treatment. Here, we report a case of inflammatory myofibroblastic tumor in the breast with the imaging findings of mammography, magnetic resonance imaging (MRI), and pathologic findings to improve the understanding of the disease.

Diagnostic Senology Unit, Azienda Ospedaliero-Universitaria Careggi, 50139 Florence, Italy.

Breast cancer (BC) is the cancer with the highest incidence in women in the world. In this last period, the COVID-19 pandemic has caused in many cases a drastic reduction of routine breast imaging activity due to the combination of various factors. The survival of BC is directly proportional to the earliness of diagnosis, and especially during this period, it is at least fundamental to remember that a diagnostic delay of even just three months could affect BC outcomes.

Multidisciplinary approach to imaging for gender-affirming surgery: engaging surgeons, radiologists, and patients to ensure a positive imaging experience.

Ann Transl Med 2021 Apr;9(7):610

Division of Pediatric and Adolescent Gynecology, Department of Surgery, Boston Children's Hospital, Boston, MA, USA.

Medical imaging plays an integral role in the preoperative evaluation and postoperative management of transgender and gender diverse (TGD) patients who pursue gender-affirming surgery. Radiology department encounters can be a source of anxiety for patients of any demographic, including TGD patients. Although most imaging modalities are considered "non-invasive", certain imaging procedures and other aspects of the radiology encounter could be considered quite invasive to the TGD patient.

Magnetic Resonance Imaging Features in Different Types of Invasive Breast Cancer: A Systematic Review of the Literature.

Cureus 2021 Mar 12;13(3):e13854. Epub 2021 Mar 12.

Cardiology, Rush University Medical Center, Chicago, USA.

Breast cancer is the most common malignancy affecting women worldwide, and early diagnosis of breast cancer is the key to its successful and effective treatment. Traditional imaging techniques such as mammography and ultrasound are used to detect and configure breast abnormalities; unfortunately, these modalities have low sensitivity and specificity, particularly in young patients with dense breast tissue, breast implants, or post-surgical scar/architecture distortions. Therefore, breast magnetic resonance imaging (MRI) has been superior in the characterization and detection of breast cancer, especially that with invasive features. Read More
