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.

PET/CT诊断乳腺癌及腋窝淋巴结状态的作用评价

目的：评价PET／CT诊断乳腺癌和腋窝淋巴结转移的临床价值。方法：对33例疑似乳腺癌病人进行PET／CT检查，定性分析肿瘤病灶、淋巴结摄取氟脱氧葡萄糖（FDG）的程度，半定量测量标准摄取值（SUV），根据乳腺和淋巴结的FDG摄取强度诊断乳腺癌和淋巴结转移，检验SUV与乳腺癌分化程度、有丝分裂计数的关联性。结果：PET／CT诊断乳腺癌和腋窝淋巴结转移的敏感度、特异度和精确度分别为92．6％、100％、93．9％和82．3％、90％、85．2％；SUV与乳腺癌分化程度、有丝分裂计数显著相关（P〈0．05）；诊断乳腺癌的Kappa指数=0．835，μ=8．48，（P〈0．01）。结论：PET／CT诊断乳腺癌和腋窝淋巴结转移的敏感度、特异度较高，作为一种非侵袭性检查方法，可提供乳腺癌在活体内的多方面生物学信息，为选择合理的手术方式及新辅助化疗提供参考，弥补传统检查方法的不足。
