Abstract

Patients with chronic lymphocytic leukemia carrying a single <i>TP53</i> hit (chromosome 17p deletion or single <i>TP53</i> mutation) demonstrate excellent progression-free survival and overall survival on ibrutinib compared with cases harboring multiple <i>TP53</i> hits. Testing <i>TP53</i> deletion/mutation combining FISH and deep next-generation sequencing should be performed for a correct patient evaluation.<i>See related article by Brieghel et al., p. 4531</i>.
