    Research Shows Genetic Approaches to Breast Cancer Screenings Yield More Accurate Results

    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.

    Department Spotlight: Children’s Infusion Services

    Help us celebrate the holiday season by sharing joy with our Children’s Infusion Services team!  Thinking about blood can make any of us squeamish, and seeing it can be even more intimidating to the children in our lives. Being treated for a condition that requires blood transfusions or chemotherapy infusions is no easy feat, especially during the holiday season. This time of year, we are proud that we can offer our pediatric patients the power of proximity and excellence by having access to high level care close to home.  The Children’s Infusion Services (CIS) department at Renown Children’s Hospital is committed to bringing the gift of quality care to our community’s youngest patients. Whether they are caring for a child with a blood disorder or giving expert infusion care for a child battling cancer, no team does what they do better than these expert nurses, medical assistants, intake coordinators and physicians.  ‘Tis the Season to Bring Hope As the only pediatric oncology and hematology program in the region, the CIS department has a lot of responsibility on their shoulders. From inpatient chemotherapy to outpatient infusion services, this team treats a long list of pediatric blood conditions including:  Pediatric cancers Anemias Immune-mediated blood disorders Sickle-cell disease Bone marrow failure syndromes Bleeding disorders  “Our team provides a large variety of services from labs draws, sedations for procedures, infusions for diagnoses such as Crohn's disease, blood transfusions, as well as chemotherapy,” said Jen Torres, RN.  “Our team works extremely well together. We try to go above and beyond for our patients every day. It may be something as simple as a hug to comfort a parent or a special birthday gift for a patient.”  “My job allows me to work with several departments and providers when coordinating care for our littlest of patients,” added Jane Strawn, Intake Coordinator. “I assure proper authorizations are in place for the care that is needed, I communicate with our families when scheduling appointments, I organize End of Treatment Celebrations, as well as birthday shout outs and work closely with our Child Life team to help make the challenging appointment little easier.”  To best serve their patients, the team thrives on being expert multitaskers. Central line care, chemotherapy administration, blood transfusions, medication management, preventative injections, lab draws, lumbar punctures, biopsies, imaging – you name it, they do it. And they do it all with the utmost focus on safety and support.  “Our days have a lot of variation, as we perform a number of different services,” said Meagan Bertotti, RN. “We provide infusions for patients with chronic or acute medical conditions and chemotherapy/biotherapy treatment to patients undergoing cancer treatments. Overall, though, we work as a team to make these difficult procedures and treatments as easy as possible for the patients and families by providing engagement and support.”  “While we handle a lot of chemotherapy treatments for pediatric patients, we also do other infusions and transfusions as well such as blood and platelet transfusions, enzyme replacement therapies, different types of injections such as Rabies vaccine or Synagis for high-risk babies who need that extra protection during the RSV season, and lab draws,” said Chelsea Angues, RN. “We care for patients that get their therapies from outside hospitals, but the patient lives within the Reno area. We receive orders from those outside hospitals to care for those patients, so they can still be with their families and not have to travel.”  As members of the Children’s Oncology Group, a highly-regarded clinical trials group where over 90% of pediatric cancer patients across the U.S. receive treatment, teams like CIS in Renown Children’s Hospital deliver the highest standard of care. This partnership is a true testament to the devoted collaboration and relationship-building this team commits to on behalf of their patients every day.  "One of the biggest accomplishments of our team is the fact that we became a member of the Children’s Oncology Group, and the Children's Infusion Center and Pediatric Oncology became one unit,” said Shelby Nolte. "Instead of being a clinic on one side and an infusion center on the other, we really came together to make it a whole unit that collaborates on almost everything.”  “We've put much time into trying to understand other departments, their flow, their rationales and their processes so we can come to a solution that benefits our patients the greatest,” added Tiffany Macie, RN. “We've taken the last few years to really build our relationships with our pharmacy staff, our lab staff and our central supply resources. Our relationship building extends beyond the walls of the Renown building as well and out to the community providers too. In the past few years, we've been able to build relationships with the providers in the community where they trust they can send us their patients for treatment and lab draws. Finally, we've spent much time working on the relationships as a team. It's emotional work we do on our unit, and these families become our family. It's important to us that we take the time to be together outside of our shifts to enjoy one another and laugh!”  In the compassionate realm of pediatric healthcare, CIS knows that the complexities of a cancer or blood disorder diagnosis can take an emotional toll on their patients and families. The team firmly believes that emotional support can be as important as the physical and medical support throughout each patient’s unique care journey, striving to be a comforting presence during daunting times.  “The most important part of my day is collaborating with the Children's Infusion team to make life manageable for the families that are going through this experience,” added Shelby Nolte, Senior Medical Assistant. “We work as a team to make life easier for the blow of a cancer diagnosis.  We are there for our families in every way.  If they need a shoulder to cry on, an ear to listen or just someone to play cards with or tell a funny story too, we are there.”  “One of the things our team does extremely well to help our patients and their families with new diagnoses is to simply meet them where they are,” said Tiffany Macie. “That looks different for every family and every patient. We work in an environment where can build relationships with our patients and their families. This allows us the unique opportunity to really get to know them. We learn their fears, their joys, their worries, what their family lives are like, and we learn how to best meet them where they are.”  Transcending the conventional boundaries of care, the CIS department closely supports each patient, offering them solace tailored to the unique fabric of each family's life.

    Optimizing Mammogram Screenings: A Genetic Approach to a Personalized Screening Schedule

    Breast cancer screening has long been a cornerstone of women's healthcare. With 1 in 8 women diagnosed with breast cancer in their lifetime1, the United States Preventive Services Task Force (USPSTF) has developed screening recommendations to help detect early-stage cancer. Notably in 2023, the USPSTF revised the recommended age for biennial mammogram screenings for women with average risk to start at age 40 instead of 502, estimated to result in 19% more lives being saved3 by starting screening earlier. While initiating screening at an earlier age offers advantages to a wide demographic, concerns about the potential of over-screening prompted research into the feasibility of identifying women with lower breast cancer risk who could safely delay mammograms. While guidelines address high-risk individuals, a notable gap exists in providing recommendations tailored to those at lower risk. To gain insight into a patient's risk level, physicians are able to utilize genetic testing to understand an individual's genetic makeup, providing precise insights into their predisposition to various health conditions, including breast cancer. Armed with this genetic information, healthcare providers could craft tailored screening strategies that align with an individual’s specific risk profile. This genetic risk-based approach underscores the value of genetics in individualizing the onset of screening to help avoid over-screening and its associated costs. Surprisingly, genetic information is not currently being widely utilized to identify women at risk of breast cancer or other diseases in clinical practice, despite its potential to make a significant positive impact for patients. A recent retrospective analysis of 25,591 women from the Healthy Nevada Project4 sheds light on the potential benefits of this genetic risk-based approach. The study classified 2,338 (9.1%) of these women as having a low genetic risk for breast cancer. What's remarkable is that these women exhibited a significantly lower and later onset of breast cancer compared to their average or high-risk counterparts. This finding suggests that it might be safe for low-risk women to delay mammogram screening by 5 to 10 years without compromising their health.
