BACKGROUND As patients with pancreas and periampullary cancer (PPC) experience improved survival rates and longevity, the focus shifts toward living life while surviving cancer. Fatigue is the most commonly reported symptom in all cancer patients. Exercise has been found to effectively decrease fatigue levels and improve physical functioning in cancer patients. STUDY DESIGN One hundred two pa...
