ABSTRACT
Background@#While treatment strategies for mantle cell lymphoma (MCL) have evolved, patients often experience disease progression and require additional treatment therapies. Ibrutinib presents a promising option for relapsed or refractory MCL (RR-MCL). This study investigated real-world treatment outcomes of ibrutinib in patients with RR-MCL. @*Methods@#A single-center retrospective analysis investigated clinical characteristics and survival outcomes of patients with RR-MCL, treated with ibrutinib. @*Results@#Forty-two patients were included, with 16 received rituximab and bendamustine, and 26 receiving anthracycline-based regimens as front-line treatment. During a median follow-up of 46.0 months, the response rate to ibrutinib was 69%, with 12 CRs and 8 partial responses. Disease progression (54.8%) and adverse events (11.9%) were the primary reasons for discontinuation. Median progression-free survival (PFS) and overall survival (OS) were approximately 16.4 and 50.1 months, respectively. Patients older than 70 years (P =0.044 and P =0.006), those with splenomegaly (P =0.022 and P=0.006), and those with a high-risk simplified Mantle Cell Lymphoma International Prognostic Index (sMIPI) (P<0.001 and P<0.001) exhibited siginificantly inferior PFS and OS. Notably, patients with a high-risk sMIPI relapsed earlier. Post-ibrutinib treatment yilded an OS of 12.2 months, while clinical trial participants demonstrated superior survival compared to those receiving chemotherapy alone. @*Conclusion@#This study underscores the importance of considering patient characteristics before administering ibrutinib as salvage therapy. Early relapse was associated with poor outcomes, highlighting the need for novel therapeutic strategies.
