However, in ovarian borderline tumor and ovarian cancer tissues, the number of positive cells of CEBPA was significantly increased, and the staining was significantly deepened, and the positive expression rate was significantly higher than that of normal ovary and epithelial ovarian cyst tissues (χ2 = 34.932, p < 0.05), as shown in Table 2. The gene discussed is CEBPA; the disease is ovarian carcinoma.
