In regard to OS, T stage [p = 0.011, HR (95% CI): 2.684 (1.253–5.752)], N stage [p = 0.003, HR (95% CI): 2.927 (1.454–5.893)], TNM stage [p = 0.008, HR (95% CI): 3.216 (1.360–7.605)], and neoadjuvant chemotherapy [p = 0.034, HR (95% CI): 3.908 (1.111–13.747)] were factors for worse OS, but neither tumor KIF2A protein high (p = 0.117) nor tumor KIF2A mRNA high (p = 0.145) were factors. The gene discussed is KIF2A; the disease is neoplasm.
