In a patient cohort enriched for CK CLL, short telomeres were found to be associated with poor\u2010risk characteristics such as unmutated immunoglobulin heavy chain variable region\u00a0(IGHV), del(11q)\/del(17p), CK\/genomic complexity (GC) and chromothripsis. The presence of short telomeres was associated with shorter time to first treatment (TTFT) in the full cohort and in cases with CK or del(17p), and in multivariable analysis as a prognostic factor, indicating the potential importance of this biomarker for CLL risk stratification.<\/jats:p>\n                  <jats:p>Commentary on Ramos\u2010Campoy et\u00a0al.
