As shown in Table 2, there was no statistically significant correlation between RAD51 protein expression and various factors, including age, FIGO stage (III, IV), lymph node metastasis, ascites, or the mean CA125 value prior to the initiation of the first chemotherapy cycle (P > 0.05). The gene discussed is RAD51; the disease is metastatic malignant neoplasm in the lymph nodes.
