MKI67 and neoplasm: Univariate analysis showed that resection style (P = 0.041, HR = 0.121, 95% CI: (0.016 ~ 0.914); tumor growth pattern (P = 0.048, HR = 0.130, 95% CI: 0.017 ~ 0.986); Ki-67 index (P = 0.005, HR = 1.206, 95% CI: 1.057 ~ 1.376); and surgical history (P = 0.049, HR = 2.914, 95% CI: 1.004 ~ 8.461) were significantly associated with PFS (Table 3).
