Health-Related Quality of Life of Patients with Chronic Myeloid Leukemia as Measured by Patient-Reported Outcomes: Current State and Future Directions.

PURPOSE OF REVIEW: Tyrosine kinase inhibitors (TKIs) allow many patients with chronic myeloid leukemia (CML) to live normal life spans but have the potential to impact patients' health-related quality of life (HRQOL). Patient-reported outcome (PRO) measures can provide valuable information to inform treatment decision-making. Here, we review pivotal studies that used PRO measures to evaluate HRQOL of patients with CML in the first-line and treatment-free remission (TFR), and identify areas for future research. RECENT FINDINGS: PRO measures commonly studied in patients with CML include the SF-36, FACT-Leu, EORTC QLQ-CML24, and MDASI CML. Cohort or cross-sectional studies provide the most data on PRO measures in patients with CML, with less information available from randomized controlled trials (RCTs). Patients with CML taking TKIs have worse HRQOL compared to matched controls, with a few studies seeing a larger effect in younger patients (< 60 years old). No single TKI consistently has better HRQOL compared to other agents. Fatigue is a predominant symptom associated with impaired HRQOL across many studies. Studies evaluating TFR show stable or improved HRQOL after TKI discontinuation. There are areas of HRQOL detrimental to patients with other types of cancer (e.g., cognition, sexuality) that warrant further evaluation in patients with CML. Understanding the HRQOL of patients with CML is increasingly important as patients live near-normal life expectancies. PRO measures have the potential to inform treatment decisions in this patient population. Future research opportunities include using PRO measures in RCTs and expanding the HRQOL topics studied in patients with CML.
