    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.

    A Cancer Diagnosis and a Move to Reno

    Michael Millman was all set to move to Reno from the Bay Area when he noticed a pimple-like growth on his forehead, and he decided to get biopsied "just in case." It was July 2020, less than six months into the COVID-19 pandemic, when Michael got the call that the biopsy came back cancerous. He was in shock. Still living in the Bay Area at the time, he immediately scheduled to have the basal cell carcinoma removed in August. After the removal, he thought he was in the clear, but a few months later, Michael noticed that his lymph nodes felt weird, and he even cut himself shaving because of some persistent swelling in the area. Given his recent history of skin cancer, Michael immediately scheduled an appointment with a specialist in the Bay Area. "I met with an ear, nose and throat doctor who suggested a fine needle biopsy of my lymph nodes, tongue and an MRI, both with and without contrast," Michael said. "I remember feeling dreadful and that I couldn't believe this was happening yet again." A Hard Decision Michael's squamous cell carcinoma, determined by the pathology report to be significantly influenced by the HPV virus, had metastasized to his lymph nodes on both sides of his neck, and his doctor said it could be stage four cancer. He remembers feeling like he was in quicksand, unsure if he should follow through with his move to Reno, or stay in the Bay Area for treatment. By now, it was early December 2020, and hospitals in the Bay Area and across the world were at limited capacity due to COVID-19. But, in what Michael describes as a positive twist of fate, the San Francisco ear, nose and throat provider he had seen about his biopsy results mentioned that he knew many providers in the oncology department at Renown, including Abhinand Peddada, MD. The San Francisco provider called Dr. Peddada's office with a referral, and Michael even remembers that Renown called him to hear more about his diagnosis before he even got the chance to call them "To be honest, I was feeling shut out in the Bay Area, and Dr. Peddada said he could help me expedite the treatment process," Michael said. "I finally felt a sense of relief." And so began Michael's 7-week chemoradiation cancer treatment program at Renown.

    Early Detection is Key to Surviving Colorectal Cancer

    Colorectal cancer is the number two cancer killer in Nevada, only second to lung cancer, yet it is also one of the most preventable. Still, in 2020, 20.7% of Nevadans said they had never been screened for this deadly disease, according to the Nevada Cancer Coalition. At the start of the COVID-19 pandemic, unfortunately many healthcare services were halted, including colorectal cancer screenings. Those delays in screenings can lead to delays in diagnoses of colorectal cancer, resulting in poorer outcomes. Per the American Cancer Society, if colorectal cancer can be found early the relative 5-year survival rate is approximately 90%. Screening is key, and it is important to engage in preventative care. Even if you have no personal or family history of colorectal cancer, ask your doctor about colorectal risk factors and when to start screening, and if you’re up to date on your screenings, talk to loved ones and make sure they are too. According to the American Cancer Society, most colorectal cancer cases are found in those without a family history. This month let us help raise awareness for colorectal cancer and the importance of routine, life-saving screenings. To learn more, we spoke to Renown Health oncology nurse Christina Alsop, APRN. What is Colorectal Cancer Colorectal cancer is a disease in which the cells in the colon or rectum grow out of control. It usually forms from precancerous polyps, or abnormal growths, in the colon or rectum, which can become malignant without presenting any symptoms. How do Screenings Work Screening tests like stool tests, colonoscopies and others can detect these precancerous polyps, so they can be removed by a physician before turning into cancer. Screening tests can also find colorectal cancer early, resulting in better treatment outcomes. As of 2021, the U.S. Preventative Services Task Force recommends adults begin colorectal cancer screenings beginning at age 45, through 75. Screening methods include a blood stool test, which needs to take place every year or a colonoscopy, which takes place every 5-10 years. Healthy Habits Can Help Stave Off Risk Routine screenings are the only way to determine colorectal health, yet some healthy habits may reduce your risk for colorectal cancer. These factors include maintaining a healthy weight, being physically active, eating a diet rich in fresh fruits, vegetables and whole grains, limiting alcohol intake and not smoking.

    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.

    Celebrating Resilience: Raquel's Remarkable Journey Through Breast Cancer Treatment

    Raquel was 33 when she was diagnosed with breast cancer. It was April 2023, when she found a lump in her breast and was referred to the William N. Pennington Cancer Institute. After comprehensive imaging, she was diagnosed with invasive lobular carcinoma, which is a type of breast cancer that begins in the milk-producing glands of the breast. Between June 2023 and January 2024, she received a total mastectomy, chemotherapy and radiation at Renown Health. “Breast cancer is uncommon in women under 40, but any woman with a mass or lump in her breast should have an exam by a physician and imaging at any age,” said Dr. Lee Schwartzberg. In fact, according to the Centers for Disease Control and Prevention (CDC), only 9% of all new cases of breast cancer in the U.S. are found in women younger than 45. “It was a pretty scary diagnosis, but I’ve been led by great people through the process,” she said. “They were so helpful and there for me throughout the chemo and radiation.” Raquel's journey through breast cancer treatment at the William N. Pennington Cancer Institute was marked by the exceptional care provided by the Renown Health team, including nurses, nurse navigators, therapists, support teams and providers. Among the dedicated professionals, Dr. Michelle Chu and Dr. Lee Schwartzberg played pivotal roles in Raquel's diagnosis and subsequent treatment plan. Their expertise, compassion and commitment to patient care left an indelible impact on Raquel's experience. Their thorough examination and comprehensive approach ensured that Racquel received the best possible care for her invasive lobular carcinoma. In addition to the care provided at Renown, Raquel greatly benefitted from being connected with a mentor by Dr. Chu. This mentor, Kayla, had undergone a similar diagnosis and treatment plan, and at the same age Raquel. They texted and called each other throughout Raquel’s treatment, providing additional support through a challenging time. As of January 2024, Raquel is done with her treatment and continues to see her care team for follow-up appointments. “I’m through the worst and ready to rebuild my life,” Raquel said. To help celebrate this milestone, Nevada Athletics invited Raquel to receive the game ball at a Nevada Men’s Basketball game. She was joined on the basketball court for this special recognition by her husband, Raul; mother, Arlene; and two daughters, Ryleigh and Rhiannon. Racquel's journey is not only a testament to her resilience but also a tribute to the invaluable contributions of Dr. Chu and Dr. Schwartzberg in guiding her towards triumph over breast cancer.
