Article Synopsis
  • The CHARM study focused on providing genetic testing and risk management for cancer to underserved populations, addressing barriers to access in low-income and low-literacy groups.
  • Conducted at Kaiser Permanente Northwest and Denver Health from 2018 to 2020, the study monitored participants for an average of 15.4 months to evaluate the use of cancer screenings and surgical procedures after receiving genetic test results.
  • Although only a small percentage of participants received actionable recommendations, those who did showed moderate engagement in risk management practices, indicating that the study successfully increased access to genetic services and preventive care without leading to overuse of these services.

Article Synopsis
  • Screening adherence for mammography and MRI is crucial for individuals with inherited genetic variants linked to higher breast cancer risk, yet it remains low in practice.
  • A study assessed the percentage of time individuals adhered to annual mammograms and breast MRIs, revealing an average adherence of 48% for mammograms and 34% for MRIs among those with certain genetic variants.
  • The findings suggest a need for further research to understand and improve adherence to these important screening practices, particularly for those with pathogenic variants in breast cancer-associated genes.

Neither direct-to-consumer (DTC) genetic testing nor predictive genetic testing for adult-onset conditions is recommended for minor children due to ethical concerns and low clinical utility. However, parents with pathogenic variants (PVs) in disease-causing genes may be interested in pursuing genetic testing that includes the familial PV for their children. The Pediatric Testing Attitudes Scale (P-TAS) was previously developed to examine high-risk parents' opinions about pediatric BRCA genetic testing for adult-onset breast/ovarian cancer.

Purpose: Germline mutations in DNA repair genes are present in approximately 10% of men with metastatic prostate cancer (mPC), and guidelines recommend genetic germline testing. Notable barriers exist, including access to genetic counseling, insurance coverage, and out-of-pocket costs. The GENTleMEN study was designed to determine the feasibility of an Internet-based, patient-driven germline genetic testing approach for men with mPC.

Article Synopsis
  • Germline genetic testing for hereditary cancer susceptibility can lead to preventative actions like prophylactic surgeries in unaffected individuals, specifically in a study within the Kaiser Permanente Northwest health system from 2010 to 2018.
  • The study analyzed data from 1020 individuals tested for high-risk genetic variants, finding only a small percentage opted for recommended risk-reducing surgeries such as mastectomy and hysterectomy based on their results.
  • Results indicate that the use of risk-reducing surgeries is lower than expected, suggesting that other factors beyond genetic test outcomes and guidelines influence individuals' decisions to undergo prophylactic procedures, warranting further investigation.

Purpose: Medical distrust has been identified as a persistent barrier to medical care, affecting preventative screening, treatment uptake, and treatment adherence. Despite this, little research to date has examined medical distrust in a genomic medicine context. The goal of this work was to assess the prevalence of medical distrust in a genomic medicine research study and examine patient-level demographic, access-related, and health-status characteristics that predict medical distrust.

Background: Diagnosis of Lynch and other hereditary colorectal cancer (CRC) syndromes through germline genetic testing has important implications for treatment and risk-management, yet guideline-recommended genetic counseling referral and attendance is suboptimal.

Methods: Our team developed an adapted patient navigation program-Pathways to Genetic Counseling-to address multilevel barriers to genetic counseling referral and receipt. This paper describes the methods of a randomized controlled trial (RCT) testing Pathways to Genetic Counseling's effectiveness at increasing genetic counseling attendance in the University of Washington Medicine health system.

Background: A critical step in access to genetic testing for hereditary cancer syndromes is referral for genetic counseling to assess personal and family risk. Individuals meeting testing guidelines have the greatest need to be evaluated. However, referrals to genetics are underutilized in US patients with hereditary cancer syndromes, especially within traditionally underserved populations, including racial and ethnic minorities, low-income, and non-English speaking patients.

Background: Limited evidence exists about how to communicate breast density-informed breast cancer risk to women at elevated risk to motivate cancer prevention.

Methods: We conducted a randomized controlled trial evaluating a web-based intervention incorporating personalized breast cancer risk, information on chemoprevention, and values clarification on chemoprevention uptake vs active control. Eligible women aged 40-69 years with normal mammograms and elevated 5-year breast cancer risk were recruited from Kaiser Permanente Washington from February 2017 to May 2018.

Intractable public health problems are influenced by interacting multi-level factors. Dynamic research approaches in which teams of scientists collaborate beyond traditional disciplinary, institutional, and geographic boundaries have emerged as promising strategies to address pressing public health priorities. However, little prior work has identified, defined, and characterized the outcomes of transdisciplinary (TD) research undertaken to address public health problems.

Identifying patients with high genetic risk for cancer has important clinical ramifications, but hereditary cancer risk is often not identified because of testing barriers at both the provider and patient level. It is unknown how to best implement appropriate genetic testing and follow-up care into an operating primary care clinic. Implementation studies to date have been conducted in high resourced facilities under optimal conditions, often not at the clinic level.

Despite clinical guidelines, programs conducting population-based screening and genetic service delivery for hereditary cancer prevention and control are rare in practice. We interviewed individuals (n = 13) instrumental in implementing seven unique clinical programs conducting either universal tumor screening for Lynch Syndrome or routine family history screening and provision of genetic services for hereditary breast and ovarian cancer in the United States. To characterize determinants of readiness to implement population-based cancer genetic service delivery models, interviews and deductive codes drew on Weiner's theory of organizational readiness for change.
