PURPOSE To evaluate the prognostic effect of lymph node ratio (LNR) in patients with locally advanced rectal cancer who were treated with curative resection after preoperative chemoradiotherapy (CRT). METHODS Between October 2001 and December 2007, 519 patients who had undergone curative resection of primary rectal cancer after preoperative CRT were(More)
BACKGROUND S-1 is an oral fluoropyrimidine that mimics infusional 5-fluorouracil. The aim of this phase II trial was to explore the clinical efficacy of the triplet regimen TIROX, which consists of S-1, irinotecan and oxaliplatin. METHODS Forty-two chemo-naive patients with metastatic colorectal cancer (mCRC) were planned to be enrolled and be treated(More)
Reduction or disruption of the blood supply to the bone is involved in the pathogenesis of osteonecrosis of the femoral head (ONFH). An altered lipid metabolism is one of the major risk factors for ONFH. Sterol regulatory element binding protein, SREBF1 activates genes regulating lipid biosynthesis. The aim of this study was to examine the association(More)
Current knowledge of community-associated (CA) meticillin-resistant Staphylococcus aureus (MRSA) carriage in hospitalized patients is incomplete. Genotypic characteristics of 637 nasal MRSA isolates from newly admitted patients in South Korea were investigated. Sequence type (ST) 72 accounted for 52.1%, 46.3%, and 52.8% of the isolates during the periods of(More)
This study was designed to investigate the differences of histologic gastritis according to the endoscopic diagnosis, and between H. pylori positive and negative gastritis, using the Sydney system. A total of 122 patients (42 duodenal ulcer, 31 chronic gastritis, 35 gastric ulcer and 14 gastric cancer) underwent endoscopy with biopsies from the antrum and(More)
In this paper, we present a novel microfluidic system with pulsatile cell storing, cell-delivering and cell culturing functions on a single PDMS platform. For this purpose, we have integrated two reservoirs, a pulsatile pumping system containing two soft check valves, which were fabricated by in situ photopolymerization, six switch valves, and three cell(More)
BACKGROUND The pandemic strain of the influenza A virus (pH1N1) in 2009 caused many complications in patients. In this study, we introduce asthmatic symptoms as a complication of pH1N1 infection in children, not having a relationship with asthma history. The aim of this study was to quantify asthmatic symptoms in pH1N1-infected children and elucidate the(More)
PURPOSE To investigate whether pretreatment serum carbohydrate antigen 19-9 (CA 19-9) levels are associated with pathological responses to preoperative chemoradiotherapy (CRT) in patients with rectal cancer. MATERIALS AND METHODS In total, 260 patients with locally advanced rectal cancer (cT3-4NanyM0) who underwent preoperative CRT and radical surgery(More)
AIM Little is known about the long-term outcome of T1 colorectal cancer (CRC) following curative resection. The present study addressed the long-term outcome of locally or radically resected T1 CRCs. METHOD A total of 430 patients with T1 CRC who underwent local or radical resection were considered. Unfavourable histological factors were defined as(More)
