Univariate analysis showed that high XB130 expression (P = 0.0045), tumour size (P = 0.024), distant metastasis (P = 0.003), TNM stage (P = 0.002) and lymphatic metastasis (P = 0.016) were independent prognostic factors of postoperative survival. This evidence concerns the gene AFAP1L2 and neoplasm.
