[Prognostication of chronic Ph+ myeloid leukemia using the PHCML.EXE computer program].

Area of Science:

• Hematology
• Oncology
• Clinical Research

Context:

• Chronic myeloid leukemia (CML) is a myeloproliferative neoplasm.
• Accurate prognostic staging is crucial for CML patient management.
• Sokal's prognostic criteria are widely used for initial risk stratification in CML.

Purpose:

• To evaluate the prognostic reproducibility of Sokal's risk score in a cohort of 193 Philadelphia chromosome-positive CML patients.
• To assess the accuracy of Sokal's staging system in stratifying patients with different risk levels.
• To determine if Sokal's age-specific formula improves prognostication for younger CML patients.

Summary:

• Sokal's prognostic criteria demonstrated prognostic discrimination at diagnosis for CML patients.
• The stratification accuracy was notably higher for patients with poorer prognoses in this cohort.
• The age-specific formula for younger patients did not offer significant prognostic advantages.

Impact:

• Findings suggest that Sokal's criteria are applicable but may require adjustments for specific patient populations.
• A modified relative risk coefficient (1.9 vs. 1.2) indicates potential differences in prognostic factor weighting.
• This study highlights the importance of validating prognostic models within diverse patient cohorts for improved CML treatment strategies.
