Key clinical point: Nearly 40% of patients with breast cancer reported severe cancer-related fatigue for up to 4 years after diagnosis, with depression and receipt of hormone therapy being the key risk factors.
Major finding: The estimated risk for severe global fatigue increased from 13.8% at diagnosis to 64.5% at 4 years postdiagnosis in 19% of patients clustered in the deteriorating group, whereas it remained persistently high in 21% of patients clustered in the high-risk group (94.8% at diagnosis and 64.6% at year 4). Depression ( P < .001) and receipt of hormonal therapy ( P = .0359) were associated with severe global fatigue trajectory.
Study details: This longitudinal analysis of the ongoing prospective CANcer TOxicity trial included 4173 women with stage I, II, or III breast cancer.
