The protein expression levels of COL10A1 and SOX9 were significantly correlated with tumor size (P = 0.016 and P = 0.023), tumor differentiation (P = 0.005 and P = 0.022), lymph node metastasis (P = 0.004 and P = 0.001), and serosal invasion (P = 0.001 and P = 0.015). This evidence concerns the gene SOX9 and neoplasm.
