Abstract
Patients with leukemia often suffer from the combined effects of cancer-related fatigue (CRF) and subthreshold depression, which mutually exacerbate each other in a vicious cycle. In this editorial, we comment on the article by Liu et al, published in the World Journal of Psychiatry. We further elucidate the profound impact of subthreshold depressive symptoms on the experience of CRF and complications in patients with leukemia. This editorial highlights the importance of early identification and treatment of subclinical depression, and advocates for a multidisciplinary and integrated treatment approach that includes social support, psychological interventions, and individualized treatment plans. Future research needs to explore the biological mechanisms underlying the interaction between the two to develop more effective prevention and treatment strategies.
