Background: Systemic inflammation responses have been associated with cancer development, progression and metastasis. However, little is known about the risk of metastasis based on inflammatory-based scores in patients with osteosarcoma before treatment. We therefore estimated the predictive value of these parameters for metastasis in osteosarcoma.
Methods: A total of 54 osteosarcoma patients were enrolled in this retrospective study. All had been diagnosed histologically, and their laboratory data at the first visit were collected from medical records. The lymphocyte-monocyte ratio (LMR), neutrophil-lymphocyte ratio (NLR), monocyte-neutrophil ratio (MNR), platelet-lymphocyte ratio (PLR), Glasgow prognostic score (GPS), neutrophil-platelet score (NPS), neutrophil counts (NC), lymphocyte counts (LC), monocyte counts (MC), and C-reactive protein (CRP) were evaluated.
Results: High values of CRP, PLR, MNR, and NPS and a low NC were significantly associated with metastasis of osteosarcoma patients in the univariate analysis. A multivariate Cox regression analysis revealed that a high CRP level (>0.6mg/dL) (hazard ratio=9.7, 95% confidence interval=3.0-31 ; p=0.00010) and low NC (<4087/µL) (hazard ratio=0.13, 95% confidence interval =0.040-0.42 ; p=0.00080) were risk factors significantly associated with metastasis of osteosarcoma patients.
Conclusions: Our study demonstrated that the combination of a high CRP level and low NC before treatment was a useful inflammatory-based prognostic indicator for metastasis in patients with osteosarcoma.
