金属内支架置入联合三维适形放射治疗肝癌合并门静脉癌栓

Objective To study the clinical efficiency of metallic stent implantation in combination with three-dimensional conformal radiation therapy in the treatment of hepatocellular carcinoma (HCC) pa-tients with portal vein tumor thrombus. Methods 22 cases of HCC patients with portal vein tumor thrombus were devided into 2 groups: 10 patients (group A) recieved stent implantation in combination with conformal radiation therapy, 12 patients (group B) recieved stent implantation and transcatheter arterial chemoembolization. The adverse reactions, and liver function before and after treatment were compared between the two groups. The stent patency rate at 4, 6 and 12 months and the survival rate at 3, 6 and 12 months were followed up. Comparison of liver function was analyzed by Wilcoxon signed rank test. Compari-son of stent patency rate curves and survival curves was analyzed by Log rank test. Results The portal vein catheterization was successful in all the patients. The stents were successfully implanted by transhepatic portal vein approach, and portal vein stenosis was re-opened. There was no abdominal hemorrhage in all the patients, but there were symptoms of abdominalgia, fever, nausea, vomiting and flatulence of varying de-grees after interventional operation, and these symptoms were relieved by symptomatic treatment in one week. All patients in group A completed the treatment. Ⅰ-Ⅱ degree gastrointestinal tract reactions occurred in 3 cases, Ⅰ-Ⅱ degree myelosuppression occurred in 2 cases, and they were all completely relieved after treatment. The stent patency rate at 4, 6 and 12 months was 90%, 70%, 30% in group A; and 50%, 25%, 16.7% in group B (P < 0.05). The survival rate at 3, 6 and 1 2 months was 100%, 80%, 30% in group A and 91.7%, 41.7%, 16.7% in group B (P < 0.05). Conclusion Stent implantation combined with three-dimensional conformal radiation therapy is a good treatment for hepatocellular carcinoma with portal vein tumor thrombus and causes less damage to liver.
