Abstract

Background: The aim of this study was to evaluate the severity and patterns of fatigue during preoperative chemoradiation therapy for locally advanced rectal cancer and determine whether there are predictors for patients who develop severe fatigue.

Methods: Seventy-two patients with resectable rectal cancer received chemoradiation (total radiation dose, 45 gray/25 fractions to the pelvis; continuous infusion of 5-fluorouracil [300 mg/m(2)]). The Brief Fatigue Inventory (BFI), a measure that categorizes fatigue severity on a 0-10 scale, was administered weekly during treatment. Severe fatigue was defined as 7-10 on the "worst level of fatigue" item. Demographics, disease information, toxicities, and blood counts were collected. Descriptive statistics, repeated measure analysis of variance, and multiple regression were used to examine fatigue and its correlates.

Results: Fatigue increased in 67% of patients during chemoradiation (CTX/XRT). The mean fatigue score increased from 3.16 before treatment to 4.62 at the end of treatment. A significant linear trend suggested that fatigue progressively got worse during CTX/XRT (F = 16.497, P < 0.001). However, 18% of patients experienced severe fatigue before CTX/XRT; this was predicted by uncontrolled pain (r(2) = 0.321; F = 16.52; P < 0.001). During CTX/XRT, uncontrolled diarrhea was the only predictor for increased fatigue (r(2) = 0.182; F = 7.77; P < 0.01). Approximately one-third of patients had severe fatigue, which impaired their function at the end of CTX/XRT.

Conclusions: Preoperative chemoradiation therapy for patients with rectal cancer was associated with progressive fatigue during therapy. Based on identified predictors for fatigue, more active pain management before CXT/XRT and bowel management during CTX/XRT might reduce cancer-related fatigue in these patients.
