Clinically Significant Fatigue in Adult Leukemia Patients: Prevalence, Predictors, and Impact on Quality of Life

Background Cancer-related fatigue (CRF) is a common distressing symptom in leukemia patients. CRF becomes clinically significant fatigue (CSF) when adversely affects health-related quality of life (HRQoL) and warrants further workup, referrals, and treatment. Objective: To assess the prevalence and predictors of CSF and assesses its impact on HRQoL in adult leukemia patients. Method Analysis was performed on 168 leukemia patients. The primary study outcomes were CSF (score ≥4) as measured by the fatigue numerical rating scale and HRQoL using a validated Functional Assessment of Cancer Therapy-Leukemia (FACT-Leu) scale. Result The prevalence of CSF was 89 (53%), with a mean score of 6.66±2.02. About 106 (63.1%) of leukemia patients had poor Health-related quality of life (HRQoL) (102.61±23.50). Overall, FACT-Leu mean score indicated that study participants had poor HRQoL (114.70±29.67). There was a statistically significant difference in HRQoL between the patients with CSF 104.89±28.82 and Non-CSF 125.76±26.71, p<0.001. Poor appetite (odd ratio: 3.02 [95% CI: 1.33-6.85]) was statistically significant predictors (p<0.010) of CSF. Dependence on caregiver (odd ratio: 3.31 [95% CI: 0.41-0.75]) and having non-CSF (odd ratio: 5.22 [95% CI: 2.44-11.19]) were found statistically significant predictors of good HRQoL. Conclusion CSF is prevalent among leukemia patients, and adversely affects their HRQoL. Holistic assessment and supportive care are needed to reduce the burden of CSF and improve leukemia patients HRQoL.
