Chronic Myeloid Leukemia: Prognosis Evaluation and Life Expectancy Factors for Improved CML Survival

Chronic myeloid leukemia (CML) has undergone a remarkable transformation in its management and prognosis since the introduction of tyrosine kinase inhibitors (TKIs). These advancements have allowed the life expectancy of patients with CML to approach that of the general population, a feat that seemed unattainable just a few decades ago. This article explores how this change has been achieved and what factors influence the prognosis of chronic myeloid leukemia.
Diving into CML Prognosis and Life Expectancy
The discovery of the Philadelphia chromosome and the subsequent identification of the BCR-ABL1 fusion protein have been fundamental to the development of TKIs, which have revolutionized the treatment of CML. Currently, patients who respond well to these treatments can expect a CML survival rate that is nearly normal. However, challenges remain for those who do not respond adequately to TKIs, as the risk of progression to more advanced stages of the disease continues to be a significant concern [1].
The evaluation of prognosis in CML is based on both patient and disease factors. Factors such as age, gender, and comorbidities play a crucial role, as do additional cytogenetic abnormalities and the type of transcript [2]. Furthermore, dynamic risk assessment, which includes monitoring the response to TKI treatment, is essential for adjusting therapeutic strategies and improving long-term outcomes [3].
An emerging goal in the management of CML is treatment-free remission (TFR), which has become an achievable target for a small group of patients who attain deep and sustained molecular responses. However, eligibility for TFR remains limited, and most patients must continue long-term treatment to maintain remission [4].
Conclusions
The management of CML has advanced significantly, allowing many patients to enjoy a CML life expectancy close to normal. However, identifying chronic leukemia prognostic factors and optimizing treatment remain active areas of research. The ability to predict which patients may achieve TFR and how to better manage those who do not respond to TKIs are critical challenges that must be addressed to further improve outcomes in CML.
