The Brazilian Group of CLL (BGCLL) proposes more restrictive treatment initiation criteria compared to IWCLL guidelines in chronic lymphocytic leukemia (CLL).
The BGCLL criteria use lower thresholds for cytopenias and exclude progressive lymphocytosis or symptoms without cytopenias as treatment triggers.
Retrospective analysis of 2511 patients from the Brazilian CLL Registry shows restrictive criteria better predict prognosis and largely spare patients from unnecessary treatment.
Patients treated for cytopenias exhibit significantly worse survival, underscoring cytopenia presence as a robust marker of disease burden.
