Expressions of ZEB2 and C-myc in epithelial ovarian cancer and their clinical significance / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the expression patterns of ZEB2 and C-myc in epithelial ovarian cancer (EOC) and the associations between their expressions and the pathological features of EOC.</p><p><b>METHODS</b>The expressions of ZEB2 and C-myc proteins were detected immunohistochemically in 191 cervical cancer tissues and 13 normal ovarian tissues. The relationship between ZEB2 and C-myc protein expressions and the clinicopathological features of EOC was evaluated.</p><p><b>RESULTS</b>ZEB2 positive expression ratea in EOC tissues and normal ovarian tissues were 49.2% (94/191) and 30.8% (4/13), respectively (P=0.007), and C-myc positive expression rates in the two tissues were 53.9% (103/191) and 15.4% (2/13), respectively (P=0.001). A high expression of ZEB2 was positively correlated with the pathological type of the tumor (P=0.003), FIGO stage (P=0.028), T stage (P=0.002), and N stage (P=0.04), and a high expression of C-myc was positively correlated with FIGO stage (P=0.035), histological grade (P=0.039), and T stage (P=0.002). C-myc and ZEB2 expressions were positively correlated in EOC (P<0.001), and their co-expression in EOC was significantly correlated with T stage (R=0.358, P<0.001) and FIGO stage (P=0.008).</p><p><b>CONCLUSION</b>ZEB2 and C-myc can promote the progression, invasion and metastasis of EOC, and their combined detection may assist in early diagnosis of EOC.</p>
