The univariable analyses identified MI >50% [odds ratio (OR), 4.160; 95% confidence interval (CI), 1.527–11.947), aberrant p53 expression (OR, 11.618; 95%CI, 3.442–37.778), MSI (OR, 4.577; 95%CI, 1.660–12.853), and CA125 ≥35 (OR, 6.865; 95%CI, 2.481–20.840) as potential risk factors for lymph node metastasis (Table 2, all p<0.01). The gene discussed is TP53; the disease is metastatic malignant neoplasm in the lymph nodes.
