Adverse Events and Economic Burden Among Patients Receiving Systemic Treatment for Mantle Cell Lymphoma: A Real-World Retrospective Cohort Study

Abstract

Background/Aim: Limited published real-world data describe adverse events (AEs) among patients treated for mantle-cell lymphoma (MCL). The aim of this retrospective study was to describe treatment patterns, AEs, and associated healthcare costs. Patients and Methods: Patients had two or more claims coded for MCL diagnosis, the first claim date (07/01/2012–05/31/2017) was the index date. Patients with pre-index MCL diagnosis or systemic treatment, or hematopoietic stem cell transplantation were excluded. Cohorts by regimen were followed for up to three lines of therapy. Results: Patients (n=395; median age 72 years; 31% female) were observed over a total of 576 lines of therapy, the most common being bendamustine plus rituximab; rituximab monotherapy; R-CHOP; and ibrutinib. The most frequent AEs were hypertension (40.5%), anemia (37.7%), and infection (36.1%). However, hepatotoxicity ($19,645), stroke ($18,893), and renal failure ($9,037) were associated with the highest medical costs per patient per month. Conclusion: Among patients receiving common systemic treatments for MCL, AEs occurred frequently; some imposed substantial inpatient care costs.
