FOXD1 and neoplasm: Univariate Cox regression analysis identified TNM stage (OS: p < 0.001; DFS: p < 0.001), tumour differentiation (OS: p < 0.001; DFS: p < 0.001) and positive FOXD1 expression (OS: p = 0.033; DFS: p = 0.027) as clinicopathological factors that might stronly affect prognosis (Table 3).
