Tracking Subclonal Mutations In Ighv-Mutated Cll With Progressive Disease

Most CLL is diagnosed with a low tumor burden with no indication for therapy. Biomarkers, such as unmutated IGHV genes, TP53 loss/mutation and raised β2M predict short time to first treatment and overall survival; however there remain patients with good risk biomarkers who nevertheless develop progressive disease. Advances in genomics and immunogenetics have lead to the discovery of new biomarkers and their integration with cytogenetic data refines outcome prediction. However these novel markers are predominantly found in IGHV unmutated cases (U-CLL).
