Abstract: OBJECTIVE:To investigate expression of the transmembrane protein 79(TMEM79) in hepatocellular carcinoma(HCC),and to analyze its correlations with clinicopathological characteristics and prognosis of the patients. METHODS:From May 2011 to August 2017,clinicopathological data of 95 patients in the Meizhou People--s Hospital with HCC who received radical surgical treatment were collected. Expression levels of TMEM79 were evaluated using immunohistochemistry. Relationships between TMEM79 expressions and clinicopathological factors were analyzed using the χ2 test. Kaplan-Meier method and Log-rank test were performed to analyze the survival time. Cox proportional risk regression model was used to analyze prognostic factors. RESULTS:The expression levels of TMEM79 in HCC was significantly correlated with the differentiation degree of HCC (χ2=8.902;P<0.05). The overall survival times (OS) and the progression-free survival times (PFS) of the negative expression group was significantly prolonged comparing with the positive expression group (P<0.01). Positive expression of TMEM79 was a risk factor for postoperative recurrences and metastases in patients with stage Ⅰa-Ⅱa [HR=2.001,95%CI (1.152,3.476),P<0.05]. Histological morphology with mass form predominantly [HR=3.090,95%CI(1.317,7.273),P<0.05] and the positive expression levels of TMEM79 [HR=3.323,95%CI (1.652,6.683),P<0.05] were independent factors affecting postoperative PFS and OS in HC C patients with stageⅠa-Ⅱa(P<0.05). CONCLUSION:Expression of the TMEM79 protein in HCC tissue was related to the degrees of HCC differentiation. The positive expression levels of TMEM79 were related to poor prognosis. Positive expression levels of TMEM79 protein can possibly be used as a predictive factor for postoperative HCC patients with stage Ⅰa-Ⅱa.
