Major changes or additions to new guidelines for chronic lymphocytic leukemia include the following:
Molecular genetics: Recognition of the clinical importance of specific genomic alterations/mutations 17p deletion and mutations in TP53 on therapeutic response.
IGHV mutational status: Immunoglobulin variable heavy chain (IGHV) genes offer important prognostic information.
Biomarkers: Soluble CD23, thymidine kinase, and beta-2-microglobulin need to be standardized and used in prospective clinical trials.
MRD: Minimal residual disease should be assessed in clinical trials aimed at maximizing remission depth.
Antiviral prophylaxis: Patients should be tested for HBV serological status before starting on an anti-CD20 agent.
