ABSTRACT

Objective To study the influence of laparoscopic radiofrequency ablation combined with intravenous chemotherapy on hepatoma cell growth mediated by PTEN and Wnt pathway. Methods 90 cases of hepatocellular carcinoma patients from May 2013 to June 2016 were chosen as study subjects, all patients were divided into observation group (n = 45), control group (n = 45) randomly. Patients in observation group received laparoscopic radiofrequency ablation combined with intravenous chemotherapy, while those in control group received intravenous chemotherapy only. One week after treatment, two groups patients' liver lesion tissue PTEN signaling pathway, Wnt signaling pathway related gene mRNA expression were detected by RT-PCR method; serum contents of tumor markers were tested by Radioimmunoassay. Results One week after treatment, liver lesion tissue PTENmRNA expression was higher in observation group than that in control group, HIF-1, VEGF mRNA expression were lower in observation group than those in control group, the difference was statistically significant (P < 0.05); liver lesion tissue Wnt pathway related genes mRNA expression such as β-catenin, CyclinD1, c-myc, MMP-7 were lower in observation group than those in control group, the difference was statistically significant (P < 0.05); serum contents of tumor markers such as AFP, GGT-Ⅱ, IGF-2, CA19-9 were lower in observation group than those in control group, the difference was statistically significant (P < 0.05). Conclusion Laparoscopic radiofrequency ablation combined with intravenous chemotherapy can inhibit the growth of HCC cells through the PTEN and Wnt pathway, which has positive clinical significance.
