As shown in Table 1, two sided Fisher's exact analysis revealed that PinX1 expression in the carcinoma tissues of the training cohort conspicuously correlated with some clinicopathological features, such as depth of invasion-pT status (P = 0.018), lymph node metastasis-pN status (P = 0.043), and TNM stage (P = 0.013). Here, PINX1 is linked to carcinoma.
