OBJECTIVE To evaluate the feasibility of an aggressive surgical approach incorporating major hepatic resection after biliary drainage and preoperative portal vein embolization for patients with hilar bile duct cancer. SUMMARY BACKGROUND DATA Although many surgeons have emphasized the importance of major hepatectomy in terms of curative resection for(More)
Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a heterogeneous enzyme abnormality with high frequency in tropical areas. We performed population screening and molecular studies of G6PD variants to clarify their distribution and features in Southeast Asia. A total of 4317 participants (2019 males, 2298 females) from 16 ethnic groups in Myanmar, Lao(More)
HYPOTHESIS While simultaneous resection has been shown to be safe and effective in patients with synchronous metastasis, neoadjuvant chemotherapy followed by hepatectomy has gradually gained acceptance for both initially nonresectable metastasis and resectable metastasis. The boundary between these treatments is becoming unclear. We hypothesized that(More)
A total of 3000 men living in Yamaguchi were screened for glucose-6-phosphate dehydrogenase (G6PD) deficiency using Beutler's spot test and three types of starch gel electrophoresis. These electrophoresis used a phosphate buffer system at pH 7.0, a TRIS-EDTA-borate buffer system at pH 8.6, and a TRIS-hydrochloride buffer system at pH 8.8. Fifteen(More)
We performed hepatectomy without lymph node (LN) dissection for intrahepatic cholangiocarcinoma (ICC) limited to the peripheral region of the liver, and hepatectomy with extrahepatic bile duct resection and regional LN dissection for any types of ICC extending to the hepatic hilum. Surgical outcomes were evaluated to elucidate the prognostic factors that(More)
A 13-year-old Hungarian boy (B.J. Jr.) with congenital haemolytic anaemia (CHA) and hyperkinetic torsion dyskinesia was found to have severe triose-phosphate isomerase (TPI) deficiency. One of his two brothers (A.J.), a 23-year-old amateur wrestler, has CHA as well, but no neurological symptoms. Both have less than 10% TPI activity and a highly increased(More)
The entire coding sequence of a Japanese class 1 variant (G6PD Tokyo) was amplified by the polymerase chain reaction from genomic DNA. Nucleotide analysis by a direct sequencing technique revealed a unique nucleotide substitution (1246 G to A) in exon 10, which predicts a Glu to Lys substitution at the 416th amino acid. This is another member of a(More)
BACKGROUND Matrix metalloproteinase-7 (MMP-7) recently has been reported to play a role in tumor cell invasion. The objective of the current study was to examine the expression of MMP-7 in patients with cholangiocellular carcinoma. METHODS Twenty-six patients underwent resection of cholangiocellular carcinoma, leaving no macroscopic evidence of residual(More)
The type-I isoform of pyrimidine 5'-nucleotidase (P5N-I) has an important role in the catabolism of pyrimidine mononucleotides during erythroid maturation. Two alternatively spliced forms of P5N-I mRNA have been identified, and we found another alternatively spliced form in reticulocytes, which included an additional 87-bp sequence. The sequence is located(More)
BACKGROUND/AIMS To evaluate our treatment protocol applied to patients with hepatocellular carcinoma. The protocol consists of the selection criteria for hepatectomy, the use of techniques that minimize intraoperative blood loss, strict follow-up after surgery, and an aggressive surgical approach for intrahepatic recurrence. METHODOLOGY We conducted a(More)
