In the 213 EOC samples, CEP55 protein levels were positively correlated with clinical stage (P < 0.001), lymph node metastasis (P < 0.001), intraperitoneal metastasis (P < 0.001), tumor recurrence (P < 0.001), differentiation grade (P < 0.001), residual tumor size (P < 0.001), ascites see tumor cells (P = 0.020), and serum CA153 level (P < 0.001). Here, CEP55 is linked to neoplasm.
