Programmed Death Ligand 1 (PD-L1) Expression in Primary Angiosarcoma
Angiosarcomas are rare malignant endothelial-cell tumors of vascular or lymphatic origin, and are among the most aggressive subtypes of soft-tissue sarcomas. The prognosis is poor and treatment is challenging in many cases. PD-1/PD-L1 pathway plays a critical role in immune escape of tumor cells. Recent studies described that PD-L1 is widely expressed in various types of cancer, providing the b...
متن کاملProgrammed death ligand 1 (PD-L1) expression and tumor infiltrating lymphocytes in glioblastoma Running title: PD-L1 expression in glioblastoma
BACKGROUND Immune checkpoint inhibitors targeting programmed cell death 1 (PD1) or its ligand (PD-L1) showed activity in several cancer types. METHODS We performed immunohistochemistry for CD3, CD8, CD20, HLA-DR, phosphatase and tensin homolog (PTEN), PD-1, and PD-L1 and pyrosequencing for assessment of the O6-methylguanine-methyltransferase (MGMT) promoter methylation status in 135 glioblastom...
متن کاملPrognostic value of programmed death-ligand 1 (PD-L1) expression in ovarian clear cell carcinoma
OBJECTIVE Programmed death-ligand 1 (PD-L1) was expressed in various tumors and antibodies targeting its receptor programmed cell death-1 (PD-1) are emerging cancer therapeutics. This study was designed to evaluate the expression of PD-L1 and its correlation with clinicopathologic features and clinical outcomes in ovarian clear cell carcinoma (OCCC). METHODS The PD-L1 expression was measured ...
متن کاملProgrammed death-ligand 1 (PD-L1) expression in various tumor types
Background Programmed cell death-1 (PD-1) is a co-inhibitory receptor expressed on lymphoid and non-lymphoidderived cells that negatively regulates peripheral T-cell responses. PD-L1, the major PD-1 ligand, is expressed on various tumors and is being investigated as a possible predictive marker for anti-PD-1 therapy. Few studies have determined PD-L1 expression across tumor types using a consis...
متن کاملIncreased expression of programmed death ligand 1 (PD-L1) in human pituitary tumors
PURPOSE Subsets of pituitary tumors exhibit an aggressive clinical courses and recur despite surgery, radiation, and chemotherapy. Because modulation of the immune response through inhibition of T-cell checkpoints has led to durable clinical responses in multiple malignancies, we explored whether pituitary adenomas express immune-related biomarkers that could suggest suitability for immunothera...
