The purpose of this pilot study is to determine the effects of a walking program on fatigue, physical functioning and QOL in patients with pancreatic and periampullary cancers who have had surgery or are undergoing adjuvant therapy with chemotherapy (CT) and/or radiation therapy (RT). This pilot study will utilize the walking program developed by Mock et al. (2001), in their investigation of the improvement of fatigue and QOL in breast care patients following surgery who were receiving CT, RT or biotherapy. No studies published to date have utilized a progressive walking program in post-operative pancreas and ampullary cancers to determine if it reduces adverse effects, such as fatigue or improves functionality and QOL scores.
