PD-L1 Expression by Two Complementary Diagnostic Assays and mRNA In Situ Hybridization in Small Cell Lung Cancer.

Introduction: Therapeutic antibodies to immune checkpoints show promising results. Programmed death-ligand 1 (PD-L1), an immune checkpoint ligand, blocks the cancer immunity cycle by binding the PD-L1 receptor (programmed death 1). We investigated PD-L1 protein expression and messenger RNA (mRNA) levels in SCLC.

Phase III safety study of rituximab administered as a 90-minute infusion in patients with previously untreated diffuse large B-cell and follicular lymphoma.

This phase III, multicenter, single-arm trial investigated the impact of 90 min rituximab infusions on infusion-related reactions (IRRs) in patients with untreated diffuse large B-cell lymphoma (DLBCL) or follicular lymphoma (FL). Patients received six or eight cycles of rituximab plus cyclophosphamide, vincristine, doxorubicin and prednisone for DLBCL or plus cyclophosphamide, vincristine and prednisolone for FL. A total of 425 patients received the first rituximab infusion per standard guidelines; median duration 240 min.
