Fat malabsorption in pancreatic cancer: Pathophysiology and management

Abstract

AbstractExocrine pancreatic insufficiency (EPI) is common in pancreatic ductal adenocarcinoma (PDAC) and may lead to significant nutrition compromise. In the setting of cancer cachexia and gastrointestinal toxicities of cancer treatments, untreated (or undertreated) EPI exacerbates weight loss, sarcopenia, micronutrient deficiencies, and malnutrition. Together, these complications contribute to poor tolerance of oncologic therapies and negatively impact survival. Treatment of EPI in PDAC involves the addition of pancreatic enzyme replacement therapy, with titration to improve gastrointestinal symptoms. Medical nutrition therapies may also be applicable and may include fat‐soluble vitamin replacement, medium‐chain triglycerides, and, in some cases, enteral nutrition. Optimizing nutrition status is an important adjunct treatment approach to improve quality of life and may also improve overall survival.
