Moreover, the vimentin expression in different components of PESC did not show any correlation with age, gender, family history, smoking, alcohol, tumor location, gross appearance, lymph node metastasis, and TNM stage (P = 1.000, 1.000, 0.309, 1.000, 0.282, 0.832, 0.188, 1.000, and 0.067, respectively, Table 5).
