Objective To evaluate the biological safety of 125I-filled carbon nanotubes covered with metallic esophageal stent with regard to the normal esophagus before clinical application.Methods 125I-filled carbon nanotubes covered with metallic esophageal stent was prepared.Eighteen of New Zealand rabbits were randomly divided into three groups with 6 rabbits in each group.Three groups of stents,non-radioactive,low radio-activity ( 3.7 - 5.6 MBq),and high activity ( 11.1 - 13.0 MBq ) were placed in the midpiece of esophagus of rabbits.Esophagus opacification and three-diamensions DSA were performed at 0.5 h,7,14 and 30 d after insertion of the stents,respectively.The rabbits were killed at 30d after insertion of the stents,and histologic examinations of the esophageal walls were performed.Results In non-radioactive and low activity groups,1 of 6 rabbits died of wound infection at 1 and 3 d after surgery due to pulmonary infection,respectively.All specimens were obtained from 16 rabbits.Microscopically,in all rabbits of low activity and high activity groups,there were membrana mucosa necrotic and swell and breakage of the muscle fiber in esophageal submucosa and muscularis,submucosal inflammation,which were more severe in high activity group.In low activity group,one esophagus ectal membrane was involved,however,esophageal perforation did not develop.In high activity group,3 of 6rabbits esophageal perforation had developed,in which one esophagus mediastinum fistula developed,without inflammation.In non-radioactive group,it was almost normal in mucosa layer,a small amount of inflammatory cells were found in submucosal layer,and part of muscle fibers was fractured and no pathological changes of necrosis was found.Conclusions Radioactive 125I carbon nanotubes covered metallic stent with low activity(3.7 -5.6 MBq) can be used as intraluminal palliative brachytherapy,which is safe and effective.

OBJECTIVETo compare the effectiveness of percutaneous microwave ablation ( MWA) versus hepatectomy for multifocal hepatocellular carcinoma.

METHODSFrom August 2002 to March 2012, one hundred and twenty-two patients with multifocal hepatocellular carcinoma (diameters 1 to 7 cm, 2 to 4 lesions) were treated by either complete MWA or radical hepatectomy, and their clinical data were collected and analyzed.The patients were divided into MWA group (n = 50) and resection group (n = 72), and the resection group was matched by MWA group based on clinical parameters. The survival and complications in the two groups were compared.

RESULTSThe overall 1-, 3- and 5-year survival rates were 100.0%, 73.0% and 62.0%, respectively, in the MWA group, and 80.0%, 56.0%, and 41.0%, respectively, in the resection group (P < 0.05). The corresponding recurrence-free survival rates were 88.0%, 63.0%, and 52.0% in the MWA group, and 68.0%, 45.0%, and 36.0%, respectively, in the resection group (P< 0.05). The multivariate Cox regression analysis indicated that albumin level, performance status, treatment modality, and tumor size were independent prognostic factors.

CONCLUSIONCompared with hepatectomy, percutaneous microwave ablation is a minimally invasive and reproducible procedure, and can improve the survival in patients with multifocal hepatocellular carcinoma.
