RESUMO
Purpose To investigate the expression of mitogen-activated protein kinase kinase kinase 3 (MAP3K3) mRNA in ovarian carcinoma patients and to explore the correlation among its expression, clinicopathological features and prognosis. Methods The expression of MAP3K3 mRNA in ovarian carcinoma and fallopian tube tissues were detected by qRT-PCR, and the correlation between MAP3K3 mRNA expression and clinicopathological features was also analyzed. Whether MAP3K3 mRNA expression could be used as an independent predictor of prognosis for patients with ovarian carcinoma was further determined. Results The expression of MAP3K3 mRNA in ovarian carcinoma was significantly higher than that in fallopian tube tissues (P＜0.05). High expression of MAP3K3 mRNA was significantly correlated with FIGO stage and Challenge model of ovarian carcinoma (P＜0.05). Kaplan-Meier survival analysis showed that the disease-free survival time and overall survival time of patients with high MAP3K3 mRNA expression were shorter than those with low expression (34 months vs 52.2 months, P＜0.05.38.6 months vs 52.5 months, P＜0.05). Univariate analysis showed that high expression of MAP3K3 mRNA was a risk factor for poor prognosis of ovarian carcinoma patients (HR=4.198, 95％C/: 1.711 ～10.302, P＜0.05). Conclusion MAP3K3 mRNA is highly expressed in ovarian carcinoma tissues. Its high expression is associated with FIGO stage, Challenge model and poor prognosis of ovarian carcinoma, which may involve in the malignant transformation of ovarian carcinoma.
