BSG and neoplasm: The distribution characteristics of CD147 were similar as D-dimer, a significantly higher positive expression was found in patients with tumor metastasis (p=0.000), larger tumor diameter (p=0.003), lower differentiation (p=0.024), lymphatic metastasis (p=0.000), TMN stage (p=0.047), and deeper invasion (p=0.000), but no significant differences in patients with different gender (p=0.532), age (p=0.285), and pathological type (p=0.827) .
