Factors associated with fatigue one month after surgery in patients with gastrointestinal cancer

Abstract

OBJECTIVE: The purpose of this study was to examine the factors associated with the occurrence of cancer-related fatigue (CRF) one month after surgery in patients with gastrointestinal cancer. METHOD: The study included 96 patients with gastrointestinal cancer (50 males and 46 females, mean age 62.7 ± 11.4 years). Data of the Cancer Fatigue Scale (CFS), 6-minute walk distance (6MWD), and hospital anxiety and depression scale (HADS) were obtained before surgery and one month after surgery. The subjects were divided into the following two groups: severe CRF group (CFS score of ≥19 points) and mild CRF group (CFS score of <19 points). Each parameter was compared between the severe and mild CRF groups. The factors associated with CRF were identified by logistic regression analysis involving factors with significant differences between the groups. RESULT: The CFS score showed a significant interaction, and the CFS score, 6MWD, and HADS score showed significant differences both before and one month after surgery between the two groups. The CFS score was significantly higher in the severe CRF group than in the mild CRF group both before and one month after surgery. Additionally, the 6MWD was significantly lower in the severe CRF group than in the mild CRF group both before and one month after surgery. The factors identified on logistic regression analysis were the preoperative CFS score and preoperative 6MWD. CONCLUSION: CRF occurring one month after surgery might be affected by preoperative fatigue and preoperative exercise tolerance.
