Data demonstrates that a proactive approach to family history assessment and genetic screening will increase early detection of inherited risk. A new original investigation article published in JAMA Network Open, “Screening Familial Risk for Hereditary Breast and Ovarian Cancer,” by authors from University of Nevada, Reno School of Medicine, Renown Health and Helix for the Healthy Nevada Project® emphasizes the critical need to increase genetic screening in identifying individuals at increased risk of breast and ovarian cancer due to family history. This landmark study calls for enhanced awareness, the adoption of genetic screening practices, and, importantly, the direct screening of family history by individuals using a simple tool such as the FHS-7 questionnaire.   Breast and ovarian cancers remain leading causes of cancer-related deaths, with genetic factors playing a key role in up to 10% of cases. The study authors advocate for wider adoption of screening protocols, simple family risk questionnaires and education about the benefits of genetic testing, not only for patients but also their family members who may share similar genetic risks.  Breast cancer is a leading cause of cancer death among women in the United States. According to the American Cancer Society, about 1 in 8 women will develop breast cancer and about 1 in 36 women will die from breast cancer. Since 1990, breast cancer death rates have declined progressively due to advancements in screening, treatment and detection. Here in Washoe County, Nev., the age-adjusted mortality rate for 2020 (last update) is 21 deaths/100,000 females due to breast cancer, which is higher and worse than the national U.S. value of 19.6. Nevada ranks near the bottom in breast and cervical cancer deaths in women according to a recent Commonwealth Fund report. Across the U.S., approximately 1.1 percent of women will be diagnosed with ovarian cancer at some point during their lifetime. The research underscores that individuals with a family history of breast and ovarian cancer have a higher likelihood of carrying genetic mutations in genes such as BRCA1 and BRCA2, which significantly elevate their cancer risk. However, many at-risk individuals remain unaware of their genetic predispositions due to limited screening practices.  Evidence suggests that “up to 80% of patients with a pathogenic or likely pathogenic (P/LP) variant in the BRCA1 and BRCA2 genes are unaware of their condition and subsequent risk for hereditary breast and ovarian cancer. Rare or less penetrant P/LP variants in genes such as PALB2, CHEK2 and ATM are even less likely to be detected. This is concerning because the lifetime risk for breast cancer exceeds 50% for women with P/LP variants in BRCA1/2 and 20% for women in P/LP variants in PALB2, CHEK2 and ATM (compared with a baseline risk of 12%).” The study also found that men with family history are just as likely to have pathogenic variants in BRCA1 and BRCA2 as women.  This is important because not only are men at increased risk of breast, prostate and other cancers, these risks are passed on to daughters, nieces and other members of the family through inheritance. Men are under-represented in the Healthy Nevada Project® and other similar population health studies. Daniel Kiser, MS, lead author of the study stated, "Our work shows that family history collected during routine medical care can be evaluated using simple criteria and used to identify patients with elevated risk for inherited cancers. Because there are a number of steps that can be taken to reduce risk, both for the patient and for their family members, following up with these patients has the potential to substantially reduce mortality and the incidence of cancer." “Prevention or early detection of disease is such an important part of healthcare,” says Bill Plauth, MD, MMM, CPE, Chief Medical Officer for Renown Health and Associate Dean for Clinical Affairs at the University of Nevada, Reno School of Medicine. “The Healthy Nevada Project® is leading the way in helping Renown Health physicians and clinicians assess family history risk of breast and ovarian cancer syndrome. This in turn, enables us to provide our at-risk patients the best available tools for prevention or to catch cancer at an earlier stage, which affords less aggressive treatment options with significantly improved survival.” The study found that routine genetic screening for individuals with a strong family history of these cancers could lead to more personalized and effective healthcare strategies, including preventative surgeries, increased surveillance, or early interventions. It also highlights the gap in awareness and access to genetic testing, particularly in underserved populations.  “One of the lessons from our work is the importance of assessing family history early and often in the healthcare journey of patients,” says Joseph Grzymski, PhD, Chief Genomics Officer of Renown Health, the Principal Investigator of the Healthy Nevada Project, and a faculty member in the Department of Internal Medicine at the University of Nevada, Reno School of Medicine. “We recommend that everyone get screened for CDC Tier 1 conditions but particularly, when family history indicates risks, genetic screening is a powerful tool for risk stratification.” Key Recommendations from the Study Authors Include: Increased Engagement of Patients with Physicians: People with a family history should discuss their history with their primary care physician or health care provider and request a genetic screening. This proactive approach to prevention will save lives. Increased Access to Genetic Testing: The need for more accessible and affordable testing options, like the no-cost screening provided by the Healthy Nevada Project®, particularly for those with a family history of breast or ovarian cancer. Increased Pre-Screening and Genetic Counseling: Providing patients with the necessary counseling to understand the implications of genetic mutations and guide their healthcare decisions. Pre-screening patients with either a personal or family history of cancer with one of several simple family history tools, such as the FHS-7 Questionnaire to determine whether they should be referred for genetic services would also help increase early identification and reduce costs.  As of January 2024, the Healthy Nevada Project® had notified 330 individuals with P/LP variants in BRCA1 or BRCA2 genes of their genetic risk, of a study population of more than 53,000 patients. The Healthy Nevada Project®, powered by Renown Health and University of Nevada, Reno School of Medicine, is one of the largest genomic studies in the United States. The genomic study is at no-cost for Nevadans and gives participants insight into different genetic traits, as well as results on their predisposition for three prevalent and serious health conditions known as the CDC Tier 1 conditions because of their significant potential to positively impact public health.

Clinical researchers with the Healthy Nevada Project co-author research paper with findings that emphasize the need for a comprehensive approach to breast cancer risk assessment – including a focus on genetic medicine – to help ensure that individuals at high risk are identified and supported proactively rather than reactively.  Breast cancer is a leading cause of cancer death among women in the United States. According to the American Cancer Society, about 1 in 8 women will develop breast cancer and about 1 in 39 women will die from breast cancer. Breast cancer is associated with increased age, hereditary factors, obesity, and alcohol use. Since 1990, breast cancer death rates have declined progressively due to advancements in treatment and detection. In Nevada there are an estimated 2,310 new breast cancer cases a year, and genetic mutations such as in the genes BRCA1 or BRCA2 remain a top risk factor for this prevalent disease. Recognizing the urgency for progress in breast cancer research, a collaborative effort between physicians, advanced practice providers and scientists from the Healthy Nevada Project® (HNP) and Helix have unveiled groundbreaking research. This study explores how genetic screenings are a necessary supplement to traditional testing methods, together offering more accurate insights into a patient's likelihood of developing breast cancer in the future. HNP is operated by Renown Genomic Medicine and the Institute for Health Innovation and is one of the largest community-based population health studies in the country. Their team works in collaboration with Helix, a leader in precision health that delivers comprehensive genomic solutions. Together, this dynamic partnership aims to understand breast cancer risk factors and pave the way for more effective preventative measures. The combined research team studied 25,591 female HNP participants to evaluate the performance of different genetic screening approaches to identify women at high risk of breast cancer. The results of this research suggest that a combined monogenic, or single-gene, and polygenic, or multi-gene, approach to breast cancer screenings helped produce more accurate results and more closely identify study participants who have a high genetic risk of developing the disease. "Based on this research, we are advocating a shift in approach which would improve breast cancer risk assessment through a combination of effective family history ascertainment and genetic screening,” said Joseph Grzymski, PhD, principal investigator of the Healthy Nevada Project, research professor at the University of Nevada, Reno School of Medicine and co-author of the breast cancer research paper. “This tailored approach, founded on the assessment of individual genetic risk, not only intends to elevate patient well-being but also will improve efficiency and equity in healthcare." Complementing the team’s research on leveraging genetics to identify women at low genetic risk of breast cancer that could safely defer mammogram screenings by five to 10 years that was released in late 2023 in JAMA Oncology, the study suggests that incorporating genetic information can assist in personalizing breast cancer screenings and optimizing the use of screening resources. "Existing disparities persist across various facets of breast cancer screening and treatment; however, genetic screening is clearly a powerful tool to help facilitate early intervention for those at higher risk,” said Jamie Schnell Blitstein, APRN, a primary care nurse practitioner at Renown Health and co-author of the breast cancer research paper. “By placing a heightened focus on risk, we underscore the pivotal role of preventative breast cancer screening.” Despite the availability of effective methods for early screening, co-authors of this research found that 78 percent of women with a family history of breast cancer had their risk ascertained only after a breast cancer diagnosis. The findings emphasize the need for a comprehensive approach to breast cancer risk assessment – including a focus on genetic medicine – to help ensure that individuals at high risk are identified and supported proactively rather than reactively.  “These findings that can profoundly impact how healthcare is delivered were only made possible by all the participants who were willing to consent to research,” said Alex Bolze, PhD from Helix and co-author of the publication. “Broad-scale collaboration projects like these between Renown Health and UNR that engage large populations where participants share both their genetic information as well as electronic health records drive advancements in preventative medicine, as well as fundamental biological research.”   The research paper was officially accepted on Jan. 29, 2024, and will be published by Elsevier, Inc. on behalf of the American College of Medical Genetics and Genomics. The contents of the paper will appear in the international journal Genetics in Medicine Open. Read the full article by visiting sciencedirect.com.

Study shows that many household wells need better drinking water treatment and monitoring Outside of Nevada’s bustling cities, private wells are the primary source of drinking water, serving 182,000 people. Yet some of the tested private wells in Nevada are contaminated with levels of heavy metals that exceed federal, state or health-based guidelines, a new study published in Science of The Total Environment shows. Consuming water contaminated by metals such as arsenic can cause adverse health effects. Scientists from DRI and the University of Hawaii Cancer Center recruited households with private wells through the Healthy Nevada Project. Households were sent free water testing kits, and participants were notified of their water quality results and recommended actions they could take. More than 170 households participated in the research, with the majority from Northern Nevada around Reno, Carson City and Fallon. “The goals of the Healthy Nevada project are to understand how genetics, environment, social factors, and healthcare interact. We directly engaged our participants to better understand environmental contaminants that may cause adverse health outcomes,” said co-author Joseph Grzymski, PhD, research professor at DRI, principal investigator of the Healthy Nevada Project®, and chief scientific officer for Renown Health. Nearly one-quarter (22%) of the private wells sampled had arsenic that exceeded safe levels determined by the Environmental Protection Agency (EPA) — with levels 80 times higher than the limit in some cases. Elevated levels of uranium, lead, cadmium, and iron were also found. “We know from previous research that Nevada’s arid climate and geologic landscape produce these heavy metals in our groundwater,” says Monica Arienzo, PhD, an associate research professor at DRI who led the study. “It was important for us to reach out to community members with private wells to see how this is impacting the safety of their drinking water.” Fewer than half (41%) of the wells sampled used water treatment systems, and some treated water samples still contained arsenic levels over EPA guidelines. Although average levels of heavy metal contaminants were lower in treated water, many homes were unable to reduce contaminants to levels considered safe. The state leaves private well owners responsible for monitoring their own water quality, and well water testing helps ensure water is safe to drink. This study shows that more frequent testing is needed to ensure Nevada’s rural communities have safe drinking water. This is particularly important as the effects of climate change and population growth alter the chemistry of groundwater, potentially increasing metal concentrations. “The results emphasize the importance of regular water quality monitoring and treatment systems,” said co-author Daniel Saftner, MS, assistant research scientist at DRI. Although the research focused on wells in Nevada, other arid communities in Western states are facing similar risks of water contamination.
