PURPOSE Most stomach surgeons have been educated sufficiently in conventional open distal gastrectomy (ODG) but insufficiently in laparoscopy-assisted distal gastrectomy (LADG). We compared learning curves and clinical outcomes between ODG and LADG by a single surgeon who had sufficient education of ODG and insufficient education of LADG. MATERIALS AND(More)
PURPOSE The present study is to investigate the clinical utility of tumor marker cutoff ratio (TMR) and develop a TMR combination scoring system based on preoperative tumor marker (TM) levels to prognosis prediction in gastric cancer. METHODS We include 1,142 patients for whom two or more TMs were measured and who underwent radical gastrectomy between(More)
Angiomyolipomas (AMLs), a form of benign mesenchymal hamartoma, arise primarily in the kidneys of patients with or without tuberous sclerosis. Extra-renal AMLs are very rare and are most commonly found in the liver. AMLs of the small intestine are exceedingly rare. Here, a case of a 28-year-old man, who presented with ileal intussusception caused by ileal(More)
BACKGROUND/AIMS Twenty-one patients with primary stage IV gastric cancer were treated with a wide-spectrum regimen, designated as FEPMTX therapy to establish an effective salvage chemotherapy. METHODOLOGY FEPMTX therapy consisted of 5-fluorouracil and the triple biochemical modulators in addition to epirubicin. The schedule comprised 3 days continuous(More)
PURPOSE The Trastuzumab for gastric cancer (GC) trial identified human epidermal growth factor receptor 2 (HER2) as a predictor of successful treatment with trastuzumab (HER2 receptor targeting agent) among patients with advanced/metastatic GC. To date, the prevalence of HER2 overexpression in the Korean population is unknown. The present study aimed to(More)
OBJECTIVE In the guinea pig-to-rat cardiac xenotransplantation model, the effect of complement depletion by using Chinese Cobra Venom Factor(CVF) on hyperacute rejection was evaluated. METHODS Cardiac xenograft from guinea pig was transplanted into the abdomen of rat after the recipient being given i.p. a dose of CVF 0.20 microgram/g. the recipients were(More)
