Table 1 summarizes the comparison of clinicopathological features between patients with and without recurrence and metastasis, showing significant differences in tumor location (P < 0.001), resection type (P = 0.013), tumor size (P = 0.010), NLR (P = 0.018), CD34 (P = 0.002) and Ki67 index (P < 0.001). This evidence concerns the gene CD34 and neoplasm.
