Real-world incidence and prevention of tumor lysis syndrome in chronic lymphocytic leukemia treated with venetoclax.

ABSTRACT:

Abstract

Venetoclax is a B-cell lymphoma 2 inhibitor used in chronic lymphocytic leukemia (CLL), which can cause tumor lysis syndrome (TLS). We aimed to determine the incidence of, and risk factors for, TLS among patients with CLL/small lymphocytic lymphoma who received treatment with venetoclax at our institution from 1 January 2016 to 31 December 2020. We included 616 venetoclax escalations among 136 patients with CLL. Overall, 74 patients (54%) underwent escalation exclusively outpatient, 35 (26%) had at least 1 planned hospitalization, and 27 (20%) were escalated exclusively inpatient. During venetoclax initiation, 86% of patients received allopurinol, 71% intravenous hydration, 18% phosphate binders, and 10% prophylactic rasburicase. Among the entire cohort, 7 patients (5.1%)
