They were non-randomly assigned to undergo treatment with transarterial chemoembolization(TACE)/transarterial embolization(TAE) + portal vein stents combined with ^(125)Ⅰ implantation(Group A) and TACE/TAE + portal vein stents only(Group B). After the operation, scheduled follow-up was performed at 6, 12 and 24 mo. The recorded information included clinical manifestations, survival rate, and stent restenosis rate. Kaplan–Meier curves, log-rank test and Cox regression were used for data analyses. RESULTS From January 1, 2010 to January 1, 2015, 54 and 57 patients were allocated to Groups A and B, respectively. The survival rates at 6, 12 and 24 mo were 85.2%, 42.6% and 22.2% in Group A and 50.9%, 10.5% and 0% in Group B. The differences were significant [log rank P < 0.05, hazard ratio(HR): 0.37, 95%CI: 0.24-0.56]. The rates of stent restenosis were 18.5%, 55.6% and 83.3% in Group A and 43.9%, 82.5% and 96.5% in Group B. The differences were significant(log rank P < 0.05, HR: 0.42, 95%CI: 0.27-0.63). Cox regression identified that treatment was the only factor affecting survival rate in this study.CONCLUSION Main portal vein stents combined with ^(125)Ⅰ can significantly improve survival rate and reduce the rate of stent restenosis.展开更多
