Context:

Chronic lymphocytic leukemia (CLL) is a B-cell malignancy.
Diagnosis and prognosis criteria have evolved with new biological insights.
Bone marrow examination is no longer routinely required for diagnosis.

Purpose:

To summarize recent advancements in understanding CLL biology.
To highlight changes in diagnostic and prognostic criteria for CLL.
To discuss the role of new tools in refining therapeutic strategies.

Summary:

New insights into chronic lymphocytic leukemia (CLL) cell biology have led to modified diagnostic and prognostic criteria.
Diagnosis now relies on blood lymphocyte morphology and immunophenotyping, obviating bone marrow examination.
