ARTICLE HIGHLIGHTS
Research background

Previous researches explored the prognostic role of the neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), lymphocyte/monocyte ratio (LMR) and Glasgow prognostic score (GPS) in osteosarcoma, but their results were inconsistent with each other.

Research motivation

To verify the prognostic value of these blood indexes in osteosarcoma patients.

Research objectives

To verify the prognostic value of these blood indexes in osteosarcoma patients.

Research methods

Several electronic databases were searched to identify relevant articles. The hazard ratio (HR) with 95% confidence interval (CI) was combined to the evaluate the association between these indicators and overall survival (OS) and disease-free survival (DFS).

Research results

Higher NLR and GPS were significantly associated with poorer OS (P < 0.001; P < 0.001) and DFS (P < 0.001; P < 0.001). However, no significant relationship of PLR and LMR and OS (P = 0.085; P = 0.338) and DFS (P = 0.396; P = 0.124) was observed.

Research conclusions

Higher NLR and GPS were related with worse prognosis in osteosarcoma.

Research perspectives

The NLR and GPS might serve as reliable and valuable prognostic indicators for osteosarcoma patients.
