Univariate analysis identified tumor differentiation (P = 0.013, HR 8.111; 95% CI 1.569–41.92), cN2 (P = 0.015, HR 7.286; 95% CI 1.478–35.915), pN (P = 0.008, HR 6.075; 95% CI 1.603–23.025), and p stage (P = 0.014, HR 5.485; 95% CI 1.42–21.184) as statistically significant predictors (Table 4). The gene discussed is CNDP2; the disease is neoplasm.
