To determine potential associations between podoplanin expression and traditional clinicopathological parameters (e.g., tumor stage, infiltration depth, groin lymph node metastasis), as well as with local recurrences, metastases, and patient’s overall survival, subsequent data analysis was conducted using Spearman correlation analysis, Fisher’s exact test and the log-rank test (Mantel-Cox). Here, PDPN is linked to metastatic malignant neoplasm in the lymph nodes.
