The results of univariate analysis showed that postoperative recurrence or metastasis was associated with primary tumor site (P = 0.003, HR = 5.930, 95% CI: 1.844 ~ 19.072); tumor size (P = 0.015, HR = 4.852, 95% CI: 1.353~17.397); resection type (P = 0.041, HR = 4.759, 95% CI: 1.063~21.306); Ki67 index (P < 0.001, HR = 9.730, 95% CI: 2.253~29.106); NLR (P = 0.032, HR = 3.152, 95% CI: 1.104~8.996) and CD34 (P = 0.004, HR = 0.145, 95% CI: 0.039~0.541) were strongly correlated, independent of age, gender, and underlying disease (Table 2). This evidence concerns the gene CD34 and neoplasm.
