Patient adherence to tyrosine kinase inhibitor therapy for chronic myeloid leukemia is crucial for treatment success. This study in resource-constrained settings found that adherence, particularly when assessed by physicians, significantly correlates with molecular response, highlighting the need for targeted interventions.
Area of Science:
- Oncology
- Hematology
- Pharmacology
Background:
- Tyrosine kinase inhibitors (TKIs) have revolutionized chronic myeloid leukemia (CML) treatment, leading to improved survival rates.
- Adherence to TKI therapy remains a significant challenge in managing CML, impacting long-term patient outcomes.
- Understanding adherence factors in resource-constrained settings is vital for public health initiatives.
Purpose of the Study:
- To investigate adherence to TKI therapy among CML patients in a resource-constrained setting.
- To identify factors contributing to nonadherence in this population.
- To correlate adherence levels with current molecular response status.
Main Methods:
- A single-center, cross-sectional, observational study was conducted in North India.
- A questionnaire-based survey using the Modified Morisky Adherence Scale (MMAS-9) and physician assessment was employed.
- Statistical analysis, including logistic regression, was performed to evaluate adherence and its correlates.
Main Results:
- Out of 333 patients, adherence was 54.95% by MMAS-9 and 90.39% by physician assessment, with no correlation between the two methods.
- A significant relationship was observed between major molecular response and adherence by both MMAS-9 and physician assessment (P < .001).
- Enrollment in a patient assistance program (Novartis Oncology Access) was significantly associated with higher adherence (P = .012).
Conclusions:
- Real-world adherence to TKI therapy in CML can be suboptimal, necessitating targeted interventions.
- Physician assessment appears to overestimate adherence compared to patient-reported measures like MMAS-9.
- Adherence is strongly linked to molecular response, underscoring its clinical importance and the need for support programs.
