IGH translocations in chronic lymphocytic leukemia: Clinicopathologic features and clinical outcomes.

ABSTRACT: The prevalence, clinicopathologic correlates, and outcomes of previously untreated chronic lymphocytic leukemia (CLL) patients with IGH-BCL2 and IGH-BCL3 translocations are not well known. Using the Mayo Clinic CLL database, we identified patients seen between March 1, 2002 and September 30, 2016 who had FISH testing performed within 3 years of CLL diagnosis. The prognostic profile, time to first therapy (TTT), and overall survival (OS) of patients with IGH-BCL2 and IGH-BCL3 translocation were compared to patients without these abnormalities (non-IGH group). Of 1684 patients who met the inclusion criteria, 38 (2.2%) had IGH-BCL2, and 16 (0.9%) had IGH-BCL3 translocation at diagnosis. Patients with IGH-BCL3 translocation were more likely to have high and very-high CLL-International Prognost
