A randomized controlled trial to evaluate the long-term outcomes of laparoscopic distal gastrectomy for gastric cancer is currently ongoing in Korea. Patients with cT1N0M0-cT2aN0M0 (American Joint Committee on Cancer, 6th edition) distal gastric cancer were randomized to receive either laparoscopic or open distal gastrectomy. For surgical quality control,(More)
Calcifying fibrous tumor (CFT) is a rare, benign mesenchymal tumor usually affecting children and young adults, and it shows a predilection for the soft tissue and the abdominal cavity. Intrinsic visceral CFT is extremely rare and we present herein the case of a 59-year-old man with an asymptomatic gastric lesion, incidentally detected 1 month before this(More)
BACKGROUND A small number of nomograms have been previously developed to predict the individual survival of patients who undergo curative resection for gastric cancer. However, all were derived from single high-volume centers. The aim of this study was to develop and validate a nomogram for gastric cancer patients using a multicenter database. METHODS We(More)
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 To evaluate factors responsible for the variability between intended and achieved corneal-flap thickness during femtosecond laser-assisted laser in situ keratomileusis (LASIK). METHODS A prospective, nonrandomized, case study was performed on 35 eyes of 18 consecutive patients who underwent LASIK surgery using the 60 kHz femtosecond laser(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)
OBJECTIVE Decreased adiponectin and increased leptin plasma concentrations are believed to be associated with the occurrence and progression of cancers such as endometrial cancer and breast cancer. The aim of this study was to explore the association of plasma adiponectin and leptin levels with the development and progression of ovarian cancer. METHODS(More)
