Clinical Outcomes and Health Care Utilization in Patients With Burkitt Lymphoma.

Abstract

Burkitt lymphoma is an aggressive B-cell lymphoma requiring intensive therapy, which places patients at risk for severe toxicity. However, few studies have described these patients' clinical outcomes and health care utilization, particularly among older adults. We conducted a retrospective analysis of adults 40 years and older with Burkitt lymphoma at Massachusetts General Hospital and Dana-Farber Cancer Institute from February 1999 to December 2020 (N = 97). We abstracted patient characteristics, clinical outcomes, and health care utilization (unplanned hospitalizations, intensive care unit [ICU] admissions) during therapy from the electronic health record. Using univariate logistic regression, we examined factors associated with rates of unplanned hospitalization and ICU admission during therapy. Among evaluable patients (median age, 69 years; 23.7% female; 19.3% with bone marrow involvement), 45.8% (38 of 83) experienced unplanned hospitalization and 23.2% (19 of 82) experienced ICU admission during therapy. Among those 70 years and older, rates of unplanned hospitalization and ICU admission were 36.8% (14 of 38) and 29.0% (11 of 38), respectively. Bone marrow involvement (odds ratio [OR], 3.00; P = .069) was associated with a nonsignificantly greater likelihood of unplanned hospitalization. Older age (OR, 1.06; P = .039), Charlson comorbidity index >0 (OR, 3.14; P = .038), and hypoalbuminemia (OR, 3.22; P = .035) were associated with greater likelihood of ICU admission. Overall, 8.7% (8 of 92) of patients died during treatment, all of whom were 70 years and older. Adults with Burkitt lymphoma experience substantial rates of unplanned hospitalizations and ICU admissions, with older adults at especially high risk for ICU admission and death during treatment. Our findings underscore the need to develop supportive care interventions for patients with Burkitt lymphoma to help improve clinical outcomes and health care utilization.
