International Workshop on CLL

Optical genome mapping was found to effectively detect most abnormalities defined by standard methods, such as chromosome banding analysis, chromosomal microarrays, and fluorescence in situ hybridization, as well as several additional abnormalities of unknown clinical significance, in patients with chronic lymphocytic leukemia.

The use of a cell-free DNA–based minimal residual disease assay demonstrated feasibility and highly concordant results compared with 4-color flow cytometry and improved MRD detection in patients with chronic lymphocytic leukemia who were treated with time-limited venetoclax, acalabrutinib, and obinutuzumab.

CRISPR/Cas9 and mRNA-based gene editing and expression was found to be feasible in evaluating primary chronic lymphocytic leukemia cells.

COVID-19 continued to result in high admission and fatality rates among patients with chronic lymphocytic leukemia during the first 13 months of the pandemic, and although risk of severe infection was determined to be independent of age, CLL status, and treatment, being age 75 years or older was revealed to be a significant risk factor for death.

H3B-8800, a splicing molecule that binds to Splicing Factor 3b Subunit 1, has been shown to delay leukemic infiltration in a model of chronic lymphocytic leukemia using NOD-SCID interleukin-2 receptor gamma mice.
