As presented in Table 1, no significant association was observed between LDHA expression levels and gender, age, location, tumor differentiation, N stage, nerve invasion, or major vascular invasion, but LDHA expression levels correlated positively with TNM stage, T stage, and serum CA199 values (P = 0.045, P = 0.001, and P = 0.029, respectively). This evidence concerns the gene LDHA and neoplasm.
