Description
Lymphocytosis is defined by an excess of lymphocytes in the blood. In staging of Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma (CLL/SLL), lymphocytosis is defined as an absolute lymphocyte count (ALC) greater than 5,000 cells/µL.
Rationale
Lymphocytosis is a prognostic factor required for staging of Chronic Lymphocytic Leukemia/Small Lymphocytic Leukemia (CLL/SLL) in AJCC 8th edition, Chapter 79, Hodgkin and Non-Hodgkin Lymphomas.
