Laparoscopic decompression of a stricture of the celiac artery caused by the median arcuate ligament in a gastric cancer patient: A case of report.

Stricture of the celiac artery caused by the median arcuate ligament induces abdominal ischemic symptoms and aneurysm near the pancreatic head. However, the need to treat asymptomatic patients is unclear. We safely performed surgical decompression of a stricture of the celiac artery by MAL in an asymptomatic patient at the same time as gastrectomy for gastric cancer.

Prognostic significance of p16(INK4a) hypermethylation in non-small cell lung cancer is evident by quantitative DNA methylation analysis.

Background: p16(INK4a) is a tumor suppressor gene frequently inactivated by aberrant promoter hypermethylation. In the present study, p16(INK4a) methylation was evaluated in non-small cell lung cancer (NSCLC) using a quantitative assay and the clinical significance of the methylation was explored.

Materials And Methods: A total of 244 tumor samples from formalin-fixed paraffin-embedded archives were examined in this study.

Hypermethylation of the MYOD1 gene is a novel prognostic factor in patients with colorectal cancer.

MYOD1 promoter methylation occurs in various malignancies including colorectal cancer. We analyzed MYOD1 methylation in 80 colorectal cancer and 74 adjacent normal tissues using MethyLight, which enabled quantitative DNA methylation analysis. The measured methylation value was expressed as a percentage of methylated reference (PMR).
