Expression of PD1 and PDL1 as immune-checkpoint inhibitors in mantle cell lymphoma

Mantle cell lymphoma (MCL) has remained incurable in most patients. The expression of PD-L1 as a prognostic and predictive marker has not been fully evaluated in MCL. The current study aimed to determine PD-1/ PD-L1 expression in MCL specimens and its significance as an immune check point inhibitor.
