The involvement of lipids in carcinogenic and developmental processes has been reported in some malignancies, but their roles in gastric cancer remain to be analyzed. In this study, we compared the lipid content of gastric cancer tissue and adjacent nonneoplastic mucosa using imaging mass spectrometry. Mass spectra were acquired from 12 sections of human(More)
This study aimed to compare short-term outcomes of minimally invasive esophagectomy (MIE) with those of open esophagectomy (OE) for thoracic esophageal cancer using a nationwide Japanese database. Overall, 9584 patients with thoracic esophageal cancer who underwent esophagectomy at 864 hospitals in 2011–2012 were evaluated. We performed one-to-one matching(More)
Staging laparoscopy (SL) is often used to diagnose peritoneal metastasis in patients with advanced gastric cancer, but accurate detection of metastasis can be difficult. We evaluated the usefulness of laparoscopic narrow-band imaging (NBI) versus conventional laparoscopic white-light imaging (WLI) for the diagnosis of peritoneal metastasis. We excised 37(More)
