Abstract
The aim of the present study was to investigate whether single nucleotide polymorphisms in the DNMT3A gene are associated with susceptibility to gastric cancer in the Japanese population. The present case-control study examined the associations between single nucleotide polymorphisms (rs6733868 and rs13428812) in DNMT3A and cancer susceptibility in 343 patients with gastric cancer and 708 subjects without gastric malignancies on upper gastro-duodenal endoscopy. Of 708 controls, 409 were classified into two groups histologically: 99 cases with and 310 cases without gastric mucosal atrophy. Overall, homozygosity for the DNMT3A rs6733868 minor allele was significantly associated with a reduced risk of gastric cancer (odds ratio [OR], 0.621; 95% confidence interval [CI], 0.402-0.958; P=0.031), especially of the intestinal type (OR, 0.494; 95% CI, 0.274-0.890; P=0.019). In subjects >60 years, rs6733868 minor allele homozygosity was significantly associated with gastric cancer susceptibility. Carriers of the rs6733868 minor allele had a reduced risk of severe gastric mucosal atrophy (OR, 0.495; 95% CI, 0.299-0.826; P=0.0069). In addition, the number of minor alleles of both rs6733868 and rs13428812 was significantly correlated with the risk of Helicobacter pylori (HP) infection (P=0.0070 and P=0.0050, respectively). However, rs13428812 was not associated with severe gastric mucosal atrophy or gastric carcinogenesis. The present results suggest that DNMT3A polymorphisms serve roles in the progression from HP infection to gastric mucosal atrophy and gastric carcinogenesis in terms of degree and manner.

Feasible and technical aspects of transcatheter arterial chemoembolization for non-resectable hepatocellular carcinoma using a 3.5-French catheter system. ABDOMINAL IMAGING 2014; 39:1304-1308.

Abstract
PURPOSE To evaluate the feasibility and technical aspects of transcatheter arterial chemoembolization (TACE) for non-resectable hepatocellular carcinoma (HCC) using a 3.5-French (Fr) catheter system. METHODS This study included 328 consecutive cases of HCC among 232 patients who underwent TACE procedures using both a 3.5-Fr catheter system and a microcatheter fitted to a 3.5-Fr system between April 2009 and November 2011. We assessed the ability to reach the catheter into the proper hepatic artery (PHA), main hepatic branch, segmental artery, and subsegmental or sub-subsegmental artery. The feasibility was rated according to the following factors: (1) the number of arteries that could be used to reach the target artery/total number of procedures using the 3.5-Fr system, (2) the rate of successful completion of the procedures without changing over to the 4-Fr system and (3) the reasons for changing over the 4-Fr system. RESULTS TACE of the PHA (27 sessions), RHA/LHA (103 sessions), segmental (31 sessions), or subsegmental/sub-subsegmental arteries (162 sessions) was performed. The rate of successfully reaching the target artery using the 3.5-Fr system was 93% (306/328 sessions). We were unable to reach the target artery in 22 sessions, including 11/8/3 procedures targeting the sub-subsegmental artery, subsegmental artery, and RHA/LHA, respectively. We changed over to the 4-Fr system in six sessions; therefore, the rate of successful completion of the procedures without changing over to the 4-Fr system was 98% (322/328 sessions). CONCLUSIONS TACE of the target artery can be successfully performed using the 3.5-Fr system in most patients with HCC.

Abstract
Acute pancreatitis can complicate non-selective transcatheter arterial embolization of hepatocellular carcinoma with an incidence ranging from 1,7% (acute clinical pancreatitis) to 40% (biological pancreatitis). This complication is thought to be related to embolization of extrahepatic arterial collaterals. We report herein a case of acute clinical pancreatitis developing within 24 hours after a second course of selective transcatheter arterial chemo-embolization into the proper hepatic artery. Neither anatomical arterial variation nor particular risk factor for acute pancreatitis could be identified. This complication is unusual after selective arterial embolization. Because it may clinically mimick a postembolization syndrome, dosage of serum pancreatic enzymes should be performed systematically in case of abdominal pain following chemoembolization.
