ABSTRACT
Purpose:
Programmed cell death 1 ligand-1 (PD-L1) and PD-1 as prognostic biomarkers have spurred considerable interest in several types of malignant tumors. In the present meta-analysis, we aimed to elucidate the clinicopathological and prognostic values of PD-L1/PD-1 in osteosarcoma.Methods:
We systematically searched PubMed, Web of Science, EMBASE, Scopus, CBM and the Cochrane Library databases up to March 3, 2018. Eligible studies assessing the relationship between PD-L1 or PD-1 expression and clinicopathological and prognostic outcomes in osteosarcoma were incorporated. Pooled relative risks (RRs) and 95% confidence intervals (CIs) were used to estimate the outcomes.Results:
Eight studies involving 413 patients were incorporated into our meta-analysis. Pooled results showed that PD-L1/PD-1 overexpression was significantly associated with metastasis (RR = 1.54, 95% CI 1.12-2.11, p = 0.008) in osteosarcoma. Furthermore, osteosarcoma patients exhibited a remarkably higher total mortality risk (RR = 1.86, 95% CI 1.09-3.17, p = 0.021) with PD-L1/PD-1 overexpression. However, no significant reduced overall survival rate (RR = 0.70, 95% CI 0.46-1.07, p = 0.103) was detected in the study.Conclusion:
Our meta-analysis indicates that PD-L1/PD-1 may serve as an important biomarker for adverse clinicopathologic features and poor prognosis in patients with osteosarcoma.
