As the Hirshberg Foundation funds invaluable patient programs and research in prevention, early diagnosis, therapies and patient care, among these paths to eradicate pancreatic cancer, prevention is at the forefront. As shared by the CDC, preventative care options including blood tests, annual screenings, surveillance, and scans are all available for various cancers and diseases. The Hirshberg Foundation is eager to empower you and your loved ones with the tools you need to take control of your health and be proactive in your cancer prevention plan. As National Cancer Prevention Month comes to a close, we encourage you and your loved ones, especially if you are at high risk, to use the resources we’ve provided to create a prevention plan that will allow you to thrive.

Begin your prevention journey by taking a personal inventory of your health. In 2021, the National Institutes for Health, discussed the importance of Pancreatic cancer epidemiology: understanding the role of lifestyle and inherited risk factors. Rethinking certain lifestyle choices, documenting your family history, and assessing your risk factors could help set a foundation for a healthier future. Tackling modifiable risk factors (smoking, obesity, diabetes and pancreatitis) are just that, modifiable. Making the decision to quit smoking, maintaining or losing weight, preventing type 2 diabetes or pancreatitis are significant steps. Speak with your doctor about how to begin addressing these important health issues.

Over time, we have found that some communities are disproportionately affected by pancreatic cancer while  genetics play an important role for others. Both are at high-risk and raising awareness is only the first step in addressing the issue. Whether you are of Ashkenazi Jewish ancestry or have a family history of diabetes, pancreatitis, or pancreatic cancer, it’s important that we address these diseases before they become life threatening. Progress continues to be made in the field of pancreatic cancer as diagnostic blood and saliva tests are in development, but our ultimate goal is to offer a cancer-free future.  After 25 years of fighting this disease on many fronts and sharing the facts, we remain confident that we are getting closer and closer to reaching this goal.

Schedule

In recognition of National Cancer Prevention Month the Hirshberg Foundation is sharing important educational resources and steps you can take to live a healthier life. The goals of prevention are to help you and your loved ones remain cancer-free and to empower our community with the resources to keep you healthy. This month we will provide resources including a prevention worksheet, share the facts about risk factors, genetics, and the role of nutrition and exercise in your prevention plan. Pancreatic cancer prevention and awareness, especially for high-risk individuals, should be a priority for every family impacted by this disease. February 4th is also World Cancer Day, a reminder for all of us to raise awareness in our community, make an appointment for a cancer screening or genetic testing, and start a new healthy living plan.

Your cancer prevention plan can become a year-round effort, however, as you start to check off your new year resolutions, this is the perfect time for a health check-in. Although pancreatic cancer remains the 3rd leading cause of cancer deaths in the U.S., taking steps to improve your health today can reduce your risk of being diagnosed. The key components to pancreatic cancer prevention include:

Know the inherited risk factors
Specific communities are disproportionately at higher risk for pancreatic cancer, learn whether you are in one of these groups.

Avoid the modifiable risk factors (obesity and smoking)
Choosing a nutritious diet, reducing stress and quitting habits including smoking and excessive drinking can extend your life.

Learn about pancreatic cancer testing and surveillance
Testing or surveillance may also be clinically recommended in instances such as a new diagnosis of a pancreas cyst or lesion.

Seek genetic counseling
Meeting with a genetic counselor can help you determine your level of risk and how to tackle challenges.

In addition to personal pre-emptive steps you can take in your everyday life, the Foundation’s Seed Grant Program continues to fund critical research and with the aim of pancreatic cancer prevention as well as therapeutics, diagnosis, immunology, and cancer biology. Thanks to these research projects, we are making strides forward everyday. Recently, the the 5-year survival rate for pancreatic cancer has increased to 12% putting it on an upward trajectory for the second year in a row. This news from the ACS (American Cancer Society) Cancer Facts & Figures Report  gives survivors and families some additional hope as they navigate a diagnosis. We are headed in the right direction, but it is just as important that individual remain pro-active in our day-to-day lives.

The most recent addition to our laboratories at UCLA, the Sahin-Toth Laboratory focuses on hereditary chronic pancreatitis, a major risk factor for pancreatic cancer. Dr. Miklos Sahin-Toth joined UCLA to work in partnership with Dr. Guido Eibl in our Translational Laboratory to better understand how genetics, obesity, diet, and inflammation contribute to pancreatic cancer acceleration.

Dr. Sahin-Toth and his researchers continue to publish extensively in renowned journals, present at conferences around the world  and receive NIH funding. With additional publications forthcoming and grant proposals under consideration, we look forward to sharing updates from Dr. Sahin-Toth and his lab in the near future.

1. Chronic progression of cerulein-induced acute pancreatitis in trypsinogen mutant mice. Pancreatology 2022, 22:248-257. PMC8941852
Jancsó Z, Sahin-Tóth M.

This is an important follow-up study on our high-impact 2020 Gastroenterology paper that described increased severity of acute pancreatitis in mice carrying a trypsinogen mutation. Here we demonstrated that this trypsinogen mutation also sensitizes mice to chronic pancreatitis. Pancreatology is the official journal of the International Association of Pancreatology and the European Pancreatic Club.

2. Misfolding-induced chronic pancreatitis in CPA1 N256K mutant mice is unaffected by global deletion of Ddit3/Chop. Scientific Reports 2022, 12:6357. PMC9012826
Németh BC, Demcsák A, Geisz A, Sahin-Tóth M.

In our seminal 2019 Gut paper, we found high levels of the signaling molecule CHOP in mice with chronic pancreatitis due to a mutation in the digestive enzyme carboxypeptidase A1 (CPA1). In this follow-up study, we demonstrated that CHOP plays no role in disease initiation or progression. In other words, CHOP is a marker rather than a driver of chronic pancreatitis. The Scientific Reports is an open-access journal publishing original research from all areas of life sciences. It is part of the prestigious Nature Research journal family.

3. Modelling chronic pancreatitis as a complex genetic disease in mice. Gut 2022 May 16. Epub ahead of print. PMC9666703
Jancsó Z, Demcsák A, Sahin-Tóth M.

Chronic pancreatitis is a complex genetic disease, and patients often carry multiple genetic variants. Here we crossed mouse strains with different pancreatitis-associated gene variants to study their combined effect. This remarkable study showed that mice with single genetic changes showed no pancreas disease; however, mice with both gene variants developed severe chronic pancreatitis. Gut is a preeminent journal in the gastroenterological sciences, published in Europe by BMJ.

Characterization of novel gene mutations found in patients with chronic pancreatitis is an ongoing project in our laboratory. Here we described functional properties of a newly identified gene variant in the digestive enzyme carboxypeptidase A1 (CPA1). Mutations in this enzyme have been known to cause hereditary pancreatitis in humans. The International Journal of Molecular Sciences is an open-access journal providing an advanced forum for a large variety of research projects, including biochemistry.

This February marks 25 years since the creation of the Ronald S. Hirshberg Translational Pancreatic Cancer Research Laboratory. A cornerstone of our research program, this lab was the first at UCLA to be solely dedicated to investigating the driving forces and biology of pancreatic cancer. Dr. Guido Eibl’s research program is consistently funded by the National Institutes of Health (NIH) and continues to deepen our understanding of the intricate ways that diet, obesity and inflammation can accelerate tumor development.

We applaud Dr. Eibl and his lab and look forward to sharing more of the progress being made through their projects.

Publications from the Translational Laboratory in 2022

1. Statins inhibit inflammatory cytokine production by macrophages and acinar to ductal metaplasia of pancreatic cells. Gastro Hep Advances 2022; 1:640-651 (PMCID: PMC9615480)
S. Ako*, Y. Teper*, L. Ye, J. Sinnett-Smith, O.J. Hines, E. Rozengurt, G. Eibl. (* dual first authorship)

This original research paper reported that statins, FDA-approved drugs to treat hypercholesteremia, inhibited early pancreatic cancer development in cell culture and animal models. At least some of the effects were mediated by inhibiting macrophages, important inflammatory cells in the pancreatic microenvironment. This study supports the notion that statins may be beneficial in reducing the risk of pancreatic cancer.

2. Opposite effects of Src family kinases on YAP and ERK activation in pancreatic cancer cells: Implications for targeted therapy. Molecular Cancer Therapeutics 2022;21(11):1652-1662 (PMCID: PMC9630827)
J. Sinnett-Smith, T. Anwar, E.F. Reed, Y. Teper, G.Eibl, E. Rozengurt.

This paper described a novel signaling crosstalk in pancreatic cancer cells. In addition, the combination of SRC inhibitor and MEK inhibitor, FDA-approved drugs to treat certain types of human cancers, very strongly inhibited pancreatic cancer growth in mice. This novel finding indicates a potential role of these drugs for a combination therapy in pancreatic cancer. 

3. Body Mass Index Trajectories Across the Adult Life Course and Pancreatic Cancer Risk. Journal of the National Cancer Institute: Cancer Spectrum 2022;6(6) (PMCID: PMC9651977)

S. Arjani, P.F. Saint-Maurice , S. Julián-Serrano, G. Eibl, R. Stolzenberg-Solomon.

In collaboration with an epidemiology group at the NCI, this manuscript described the risk of developing pancreatic cancer in humans with various body mass index (BMI) trajectories across their adult life. It unequivocally shows that subjects that were overweight and/or obese as young adults and stayed in the overweight/obese category later in life carry the greatest risk of developing pancreatic cancer. The risk was greater in males than in females.

The Hirshberg Foundation is happy to share that Shelby Yaceczko, MS, RDN-AP, CNSC will be joining us at the 17th Annual Symposium on Pancreatic Cancer to discuss nutrition management post-diagnosis.

This interactive discussion will explore nutrition principles after a diagnosis of pancreatic cancer and what both patients and caregivers should know. We will review the importance of diet and wellness at every phase of the pancreatic cancer journey including meal planning and symptom management as it relates to food.

Shelby Yaceczko works with the Integrated Practice Unit (IPU) at UCLA leading the Nutrition for Safer Surgeries Program, funded through the Hirshberg Foundation. This program aims to provide early nutrition assessment and intervention for any patient with a new or existing gastrointestinal cancer diagnosis, with a special focus on pancreatic cancer. Shelby provides medical nutrition therapy services covering a range of areas such as preventing or correcting nutritional deficiencies, enhancing quality of life during cancer treatment, minimizing side effects from cancer treatments, and providing personalized nutrition prescriptions and goals to both patients and caregivers. She knows how important nutrition is before, during, and after cancer treatment and its related surgeries, and this new program aims to support patients and their caregivers throughout the process.

Shelby Yaceczko is one of few advanced practice registered dietitian nutritionists in California. She holds a master’s degree in Exercise Physiology and is currently finishing her Doctor of Clinical Nutrition studies. Additionally, she is board certified in sport nutrition, transplant nutrition, and nutrition support. Shelby focuses her efforts on providing personalized nutrition therapy in the treatment of complex disease states at UCLA Health including nutrition for cancer, gastrointestinal surgeries, and improving the general wellness of patients through diet and lifestyle changes. She understands that good nutrition is a catalyst to help you thrive and reach life potential. Shelby is described as passionate and innovative, while firmly believing in the mind-body connection. Throughout her career, she has worked to empower people of all ages to better understand the power of nutrition and its impact on overall well-being and disease management.

Nutrition plays an important role at all stages of treatment and it is one of the most requested topics at our annual Symposiums. We look forward to hearing Shelby Yaceczko’s, MS, RDN-AP, CNSC presentation on Dietary Management Post-Diagnosis.
