Abstract:
Objective To investigate the expression of E6-associated protein(E6AP)and BRG1-associated factor 155(BAF155)in patients with hepatitis B virus-related hepatocellular carcinoma(HBV-HCC)and its clinical prognostic significance.Methods A total of 126 patients with HBV-HCC diagnosed and treated in the First Affiliated Hospital of Harbin Medical University from January 2019 to February 2021 were retrospec-tively collected as the research subjects.The expressions of E6AP and BAF155 in cancer tissues and adjacent tissues of HBV-HCC patients were detected by real-time fluorescence quantitative PCR and immunohisto-chemistry.To analyze the relationship between the levels of E6AP mRNA and BAF155 mRNA and the clini-copathological characteristics of patients with HBV-HCC.The survival curve was plotted using the Kaplan-Meier method to analyze the effects of E6AP mRNA and BAF155 mRNA levels on the survival prognosis of patients with HBV-HCC.COX regression analysis was conducted to analyze the factors influencing the surviv-al prognosis of patients with HBV-HCC.Results Compared with adjacent tissues,the positive rates of E6AP mRNA and protein in cancer tissues of HBV-HCC patients were lower,while the positive rates of BAF155 mRNA and protein were higher,and the differences were statistically significant(P<0.05).Compared with the stage I of the China Liver Cancer Staging(CNLC),the maximum tumor diameter<5 cm and HBV-DNA negative,the E6AP mRNA was lower and the BAF155 mRNA was higher in the HBV-HCC cancer tissues of the CNLC stage Ⅱ—Ⅲ,the maximum tumor diameter≥5 cm and the HBV-DNA positive,the difference was statistically significant(P<0.05).The 3-year survival rates of the high-expression group and the low-expres-sion group of E6AP mRNA were 67.19%(43/64)and 38.71%(24/62),respectively,and the difference was statistically significant(Log rank χ2=10.540,P=0.001).The 3-year survival rates of the high-expression group and the low-expression group of BAF155 mRNA were 42.62%(26/61)and 63.08%(41/65),respec-tively,and the difference was statistically significant(Log rank χ2=6.876,P=0.009).The results of multi-variate COX analysis showed that CNLC stage Ⅱ—Ⅲ and BAF155 mRNA were risk factors affecting the prognosis of HBV-HCC,while E6AP mRNA was a protective factor.Conclusion The expression of E6AP is down-regulated and the expression of BAF155 is up-regulated in patients with HBV-HCC.Detecting the ex-pressions of E6AP and BAF155 is helpful for evaluating the prognosis of patients with HBV-HCC.
