Furthermore, excluding the CPH index, the ROMA index, and the R2 predictive index, a multivariate analysis showed that laterality, tumor diameter, D-dimer, CEA, and HE4 were the independent factors (HR: 0.22, 95% CI: 0.08–0.65, p = 0.006; HR: 12.68, 95% CI: 4.21–38.22, p < 0.001; HR: 5.13, 95% CI: 1.81–14.53, p = 0.002; HR: 4.36, 95% CI: 1.75–10.85, p = 0.002; HR: 3.85, 95% CI: 1.37–10.82, p = 0.011, respectively) (Table 4). The gene discussed is CEACAM5; the disease is neoplasm.
