CEP55 and ovarian carcinoma: However, CEP55 expression was markedly associated 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) in patients with ovarian cancer.
