Prognostic scores are an important tool in medical statistics. In chronic myeloid leukaemia (CML), prognostic models have existed for many years, enabling the classification of patients into groups that can be clearly differentiated in terms of their prognosis. However, over time, the focus of these models has shifted from solely survival outcomes to a broader range of diverse endpoints. This review explores the development and applications of these scores, offering recommendations for their use, and looks ahead to potential future advancements in the field. As the landscape of CML treatment evolves with newer therapeutic options, it is crucial to adapt prognostic models to reflect not only survival rates but also other important clinical milestones such as molecular remission, progression-free survival, and CML-related survival. The continued refinement of these tools, alongside international validation efforts, will be essential in providing clinicians with more accurate and individualized patient prognostication, ultimately improving therapeutic decision-making and patient outcomes.
