Background And Objectives: While several studies have evaluated neonatal intensive care unit (NICU) parents' perspective on the utility of genetic testing in a research context and concluded positive appraisal, some data point to more varied perceptions.

Methods: We conducted semi-structured interviews to elicit NICU parents' beliefs about the ways in which clinical (non-research) genetic testing could be both helpful and harmful.

Results: We interviewed 43 parents of 36 neonates who had been recommended, and either accepted or declined, clinical genetic testing.

Objective: To delineate specific ways in which neonatologists integrate genetic information into their clinical decision making.

Study Design: We employed chart-stimulated recall, in which neonatologists described how they used genetic tests in specific patient cases, as well as semi-structured questioning about genetic information.

Results: Based on 28 interviews with neonatologists, we document 6 uses of genetic information: making a diagnosis, categorizing/stereotyping as "genetic," informing prognosis, influencing treatment, informing goals of care, and supporting accountability.

Purpose: Current literature reports strong support among parents for genetic testing for ill neonates; yet, some parents decline this testing for unknown reasons. We aimed to document the proportion of parents who decline, describe their clinical and demographic characteristics, and categorize their rationales.

Methods: We reviewed medical records to collect and compare clinical and demographic information for patients whose parents consented to and declined recommended genetic testing.

Background: Despite the association of pathogenic variants (PVs) in cancer predisposition genes with significantly increased risk of breast cancer (BC), uptake of genetic testing (GT) remains low, especially among ethnic minorities. Our prior study identified that a patient decision aid, RealRisks, improved patient-reported outcomes (including worry and perceived risk) relative to standard educational materials. This study examined patients' GT experience and its influence on subsequent actions.

Article Synopsis
  • - The study evaluates the incidence of trastuzumab-induced cardiotoxicity (TIC) and left ventricular ejection fraction (LVEF) recovery in a diverse group of patients with HER2-positive breast cancer, finding that TIC occurs in about 10.6% of patients.
  • - Among the 496 patients studied, non-Hispanic Black (NHB) individuals had a higher rate of TIC but lower rates of LVEF recovery compared to non-Hispanic Whites (NHW), although race/ethnicity was not a significant predictor after accounting for other cardiovascular disease risk factors.
  • - Key factors associated with increased risk of TIC included older age, lower baseline LVEF, the use of anthracy

Retrospective case studies are one approach to help identify processes underlying the translation of successful health interventions. This case study investigates the development of and (), decision support tools for breast cancer risk assessment, and risk-stratified prevention. Following a recently developed protocol for retrospective translational science case studies, we examined the career trajectory of Dr Katherine Crew as she expanded from basic science to interdisciplinary, patient-oriented research in oncology and began collaboration with Dr Rita Kukafka, a public health informatician focused on communicating risk.

Background: Women with high-risk breast lesions, such as atypical hyperplasia (AH) or lobular carcinoma in situ (LCIS), have a 4- to tenfold increased risk of breast cancer compared to women with non-proliferative breast disease. Despite high-quality data supporting chemoprevention, uptake remains low. Interventions are needed to break down barriers.

The drug's activity at the target tissue could help to define the minimal effective dose to promote cancer preventive therapy. Here we present exemestane and sex hormone concentrations within breast tissue from a presurgical study of alternative exemestane schedules. Postmenopausal women candidates for breast surgery for estrogen receptor-positive breast cancer were randomly assigned to exemestane 25 mg once daily (QD), 25 mg 3 times/week (TIW), or 25 mg per week (QW) for 4-6 weeks before surgery.

Article Synopsis
  • - The rise of breast implant-associated anaplastic large cell lymphoma (ALCL) has prompted the FDA to label silicone and saline implants with a "black-box" warning, pushing for a deeper examination of cancer registry data to validate ALCL cases.
  • - A study analyzing New York State Cancer Registry data from 2007 to 2019 found 28 confirmed ALCL cases among 47,466 patients, with the ICD-O-3 code for ALCL showing high sensitivity and specificity.
  • - The findings suggest that previous studies may have significantly underestimated the risk of ALCL by at least 20%, calling for updated risk assessments and improved case identification methods globally.

Deep learning-based mammographic evaluations could noninvasively assess response to breast cancer chemoprevention. We evaluated change in a convolutional neural network-based breast cancer risk model applied to mammograms among women enrolled in SWOG S0812, which randomly assigned 208 premenopausal high-risk women to receive oral vitamin D3 20 000 IU weekly or placebo for 12 months. We applied the convolutional neural network model to mammograms collected at baseline (n = 109), 12 months (n = 97), and 24 months (n = 67) and compared changes in convolutional neural network-based risk score between treatment groups.

Introduction: Women with atypical hyperplasia (AH) or lobular carcinoma in situ (LCIS) have a significantly increased risk of breast cancer, which can be substantially reduced with antiestrogen therapy for chemoprevention. However, antiestrogen therapy for breast cancer risk reduction remains underutilized. Improving knowledge about breast cancer risk and chemoprevention among high-risk patients and their healthcare providers may enhance informed decision-making about this critical breast cancer risk reduction strategy.

Article Synopsis
  • The study focused on how a web-based decision aid (DA) affected BRCA1/2 genetic testing intentions and completions among 50 Orthodox Jewish women, given their unique cultural and religious contexts.
  • Results showed that while the DA improved knowledge about genetic testing and reduced decisional conflict, it did not increase the intention or completion rates for genetic testing over time.
  • Recommendations suggest that future efforts should address specific barriers to testing and involve input from community leaders to enhance uptake.

Research on polygenic risk scores (PRSs) for common, genetically complex chronic diseases aims to improve health-related predictions, tailor risk-reducing interventions, and improve health outcomes. Yet, the study and use of PRSs in clinical settings raise equity, clinical, and regulatory challenges that can be greater for individuals from historically marginalized racial, ethnic, and other minoritized communities. As part of the National Human Genome Research Institute-funded Electronic Medical Records and Genomics IV Network, we conducted online focus groups with patients/community members, clinicians, and members of institutional review boards to explore their views on key issues, including PRS research, return of PRS results, clinical translation, and barriers and facilitators to health behavioral changes in response to PRS results.

In a 3-arm presurgical trial, four-six weeks exemestane 25 mg three times/week (TIW) was non-inferior to 25 mg/day (QD) in suppressing circulating estradiol in postmenopausal women with ER-positive breast cancer. Since obesity may decrease exemestane efficacy, we analyzed changes in sex steroids, adipokines, Ki-67, and drug levels in relation to obesity. Postmenopausal women with early-stage ER-positive breast cancer were randomized to either exemestane 25 mg QD (n = 57), 25 mg TIW (n = 57), or 25 mg/week (QW, n = 62) for 4-6 weeks before breast surgery.
