The univariate analysis indicated that tumor site (P = 0.022), Enneking’s surgical staging (P = 0.000), occurrence of metastasis (P = 0.000), GPS (P = 0.000), CRP (P = 0.000), NLR (P = 0.000), PLR (P = 0.030) and LMR (P = 0.020) were associated with OS. The gene discussed is CRP; the disease is neoplasm.
