The highest prevalence and severity of weight loss is found in patients with which types of cancer?

• A. Lung and colon
• B. Breast and ovarian
• C. Prostate and testicular
• D. Pancreatic and gastric

Answer: (D)

Weight loss in cancer is driven by a combination of reduced intake, malabsorption, and a systemic catabolic state from tumor-related inflammation. Among cancer types, pancreatic and gastric cancers most strongly provoke weight loss and cachexia. Pancreatic cancer often causes exocrine pancreatic insufficiency, leading to fat malabsorption and energy loss, while both pancreatic and gastric tumors frequently produce early satiety, fullness, nausea, vomiting, or mechanical obstruction that markedly reduce oral intake. The combination of poor intake and a profound inflammatory-driven metabolic response accelerates muscle and fat wasting, resulting in the highest prevalence and severity of weight loss seen in these cancers. Other cancers can cause weight loss as well, but generally to a lesser extent.
