Fatigue and Pancreas and Bile Duct Cancer Study

Pancreatic cancer (PC) is the fourth leading cause of cancer death in men and fifth in women in the US (Jemal, Sigel, Ward, Murray, Xu, Thun et al., 2007). According to the American Cancer Society, the reported incidence of PC is roughly 37,000 cases per year, with approximately 33,000 annual deaths (2007). Periampullary cancers are less common; there were 9,250 incident cancers of the biliary tract in 2007, with 3,250 resultant deaths (Jemal et al., 2007). Five-year survival rates for untreated PC and periampullary cancers are poor, approximately 4%. Surgery offers the only hope of a cure for these patients. Following resection, the reported median survival is 12-18 months, with a five-year survival of 10-40% for patients with PC (Cleary, Gryfe, Guindi, 2004; Ishikawa, Ohihashi, Yamada, Sasaki, Imaoka, Nakaizumi et al., 2002; Sohn, Yeo, Cameron, Koniarais, Kaushal, Abrams, et al., 2000; \& Conlon, Klimstra, \& Brennan, 1996) and somewhat higher rates for patients with periampullary cancers. Five-year post-resection survival rates may approach 40% when performed at specialized major medical institutions and when favorable pathologic predictors are identified (Sohn et al.). In recent years, improved post-resection survival is due in part to lower perioperative mortality, and partially due to aggressive resection of early, low stage tumors. Long-term survival is considerably lower when resection is performed at low volume pancreatic surgery institutions and postoperative mortality is significantly higher (Birkmeyer, Siewers, Finlayson, Stukel, Lucas, Batista, et al., 2002). As patients with pancreatic and periampullary cancers experience improved survival rates and live longer, issues regarding adverse symptoms, physical function and quality of life become more important. Fatigue and pain are commonly reported symptoms in patients undergoing CT and RT, with fatigue the most universally reported symptom (Given, Given, McCorkle, Kozachik, Cimprich, Rahbar, Wojcik, 20002). Fatigue can lead to a decrease in activity levels and in one's overall QOL. Exercise has been found to effectively decrease fatigue levels and improve functional capacity in patients with breast and prostate cancer (Mock, Pickett, Ropka, Lin, Rhodes, McDaniel, et al. 2001; Segal, R., Reid, R., Courneya, K, Malone, S., Parliament, M., Scott, C., et al., 2003; MacVicar, Winningham, \& Nickel, 1989). No study to date has reported on the effects of an exercise program on fatigue levels, physical functioning or QOL in post-operative pancreatic and periampullary cancer patients. This pilot study will employ a quasi-experimental study design that is prospective in nature and randomizes patients to either the intervention group or the usual care group. Participants will complete the Piper Fatigue Scale (PFS) and the MOS SF-36 QOL questionnaire post-operatively prior to hospital discharge or at the first office visit, and again at the end of six months or at the conclusion of adjuvant treatment.
