    Summary

    This study developed clinical staging systems for hairy cell leukemia (HCL) patients. These systems predict survival at diagnosis and post-splenectomy, aiding therapy choices and clinical trial planning.

    Area of Science:

    • Hematology
    • Oncology

    Background:

    • Hairy cell leukemia (HCL) is a rare B-cell chronic lymphoid leukemia.
    • Accurate prognostic tools are crucial for HCL patient management.

    Purpose of the Study:

    • To develop clinical staging systems for HCL patients.
    • To predict survival at diagnosis and after splenectomy.
    • To identify HCL patients who benefit from splenectomy.

    Main Methods:

    • Analysis of 391 HCL patients from 22 centers.
    • Proportional hazard survival model utilized.
    • Staging systems developed based on hemoglobin, spleen size, and neutrophil count.

    Main Results:

    • A 3-stage system (I-III) based on hemoglobin and spleen size predicts survival at diagnosis.
    • Splenectomy indicated for large spleens or palpable spleens with anemia.
    • A post-splenectomy staging system (A-C) based on hemoglobin and neutrophils identifies poor prognosis.

    Conclusions:

    • Developed staging systems are validated by an independent patient series.
    • These systems can guide HCL therapy selection.
    • The staging systems are valuable for planning HCL clinical trials.
