PD-L1 Expression in Advanced Osteosarcoma

July 30, 2018 updated by: Peking University People's Hospital

The Expression of Programmed Death Ligand-1 (PD-L1) on Advanced Osteosarcoma Tissue and Its Influence on Prognosis

The expression level of PD-L1 on tumor cells is a pivotal point which might have some influence on prognosis, especially for those who might use PD-1 or PD-L1 antibody for treatment. The aim of this study is to detect the expression of PD-1 on advaced osteosarcoma patient who might use these antibodies for treatment. All those specimen should be taken by pathologist and confirmed with high tumor cellularity.
