Abbreviations: CT, chemotherapy; FSI, Fatigue Symptom Inventory; NC, noncancer controls; POMS-FAT, Profile of Mood States Fatigue Scale; RT: radiotherapy only; SD, standard deviation; T1, Time 1 (6 months after the completion of treatment); T2, Time 2 (42 months after the completion of treatment).
The severity of fatigue was rated from 0 (not at all fatigued) to 10 (as fatigued as I could be) as follows: FSI most, the most fatigued in the past week; FSI least, the least fatigued in the past week; FSI average, average fatigue in the past week; FSI now, fatigue right now. The degree to which fatigue interfered in the past week (FSI interference) was rated from 0 (no interference) to 10 (extreme interference). Fatigue frequency was assessed according to the number of days in the past week (range from 0 (none) to 10 (entire), 0–7 days) patients felt fatigued (FSI days) and how much of the day they felt fatigued (FSI time).
