B3GAT1 and neoplasm: We found that CD57+ lymphocyte infiltration was significantly inversely associated with lymph node metastasis (OR = 0.36, 95% CI 0.26 to 0.50, P = 0.000) and TNM stage (OR = 2.14, 95% CI 1.11 to 4.11, P = 0.022), but not with tumor differentiation (OR = 0.78, 95% CI 0.51 to 1.17, P = 0.229), or vascular invasion (OR = 0.58, 95% CI 0.11 to 3.09, P = 0.525) of patients.
