In addition, multivariate analyses indicated that MLK7-AS1 expression (P = 0.017), TNM stage (P < 0.001), depth of invasion (P = 0.004), and lymph node metastasis (P = 0.023) were independent prognostic indicators for OS in ovarian cancer patients (Fig. 1f). The gene discussed is MAP3K20; the disease is metastatic malignant neoplasm in the lymph nodes.
