The result indicated that the expression of ATGL was related to the clinical stage (P = 0.018), T classification (P = 0.010) and CD8 expression (P = 0.007), but not with gender, age, N classification, M classification, intravascular tumour thrombus, nerve invasion, PDL1 expression and PD1 expression (Table 1). This evidence concerns the gene CD274 and neoplasm.
