Abstract:
Objective:To investigate the relationship between expressions of OCT-4, CD117 and clinicopathological features and prognosis of patients with ovarian cancer.
Methods:A total of 70 paraffin-embedded tissues of patients with ovarian cancer from January 2010 to February 2016 in Shanxi Provincial Cancer Hospital were collected. The expressions of OCT-4 and CD117 were detected by immunohistochemistry.
Results:OCT-4 was mainly expressed in cytoplasm, while CD117 was expressed in cell membrane and cytoplasm. The positive expression rate of OCT-4 was 74.3% (52/70), and the positive expression rate of CD117 was 68.6% (48/70). The positive expression rates of OCT-4 in ovarian cancer tissues with poorly differentiation and high CA125 levels (≥500 U/ml), no peritoneal effusion and sensitive to chemotherapy drugs were 92.1% (35/38), 87.5% (28/32), 88.9% (24/27), and 78.7% (48/61), respectively, which were higher than those in ovarian cancer tissues with well and moderately differentiation, low CA125 levels (<500 U/ml), peritoneal effusion and resistance to chemotherapy drugs, the differences were statistically significant (P values were 0.000, 0.020, 0.047, and 0.043). The positive expression rates of CD117 in ovarian cancer tissues with poorly differentiation and peritoneal effusion were 84.2% (32/38) and 79.1% (34/43), respectively, which were higher than those in ovarian cancer tissues with well and moderately differentiation and no peritoneal effusion, the differences were statistically significant (P values were 0.006 and 0.017). Patients with OCT-4-positive expression, peritoneal effusion, and poorly differentiation had a shorter overall survival time (all P < 0.05). The peritoneal effusion and differentiation were independent prognostic factors in patients with ovarian cancer (both P < 0.05).
Conclusion:OCT-4 can be used as an important reference for predicting drug sensitivity and evaluating prognosis in patients with ovarian cancer.
