Patient Resiliency and Cachexia Biology
Pancreatic diseases inflict a huge burden of suffering on patients, dramatically impacting their quality of life. Patients with pancreatitis frequently have severe pain that requires prolonged hospital stays and significantly limits their activities once discharged; after recovery, many suffer from malnutrition. In patients with pancreatic cancer, even small pancreatic tumors will induce cachexia, a major barrier during treatment in addition to quality of life.
The Brenden-Colson Center for Pancreatic Care is dedicated to improving patient resiliency and quality of life through supporting research critical for understanding drivers of cachexia, malnutrition, and other debilitating symptoms. We are discovering novel treatment options and anticipate that increasing resiliency will decrease the length of post-surgical hospital stays and increase survival time.
Ongoing Research Projects
While the exact mechanisms linking pancreatic cancer to cachexia are unknown, our physicians and researchers are working to identify anti-cachexia agents and blood-based biomarkers. The ultimate goal is to integrate these discoveries into our Pre-habilitation program, which is designed to help patients become as healthy as possible before surgery or chemotherapy through nutritional, pharmaceutical, and behavioral therapy.
- Some of our current research focuses on understanding the role of pancreatic cancer extracellular vesicles (submicron-sized particles secreted by cells) in neuroinflammation and visceral pain.
- We are also investigating how metabolic reprogramming and undernutrition impact pancreatic cancer cachexia.
Dr. Aaron Grossberg is leading an effort to incorporate cachexia metrics into the Pancreas Translational Tumor Board and our clinical workflow. His lab is optimizing a method to quantify muscle wasting by analyzing pre-surgical CT images. Implementing this metric would provide vital prognostic information to clinicians and could be used to better understand patient outcomes.
