Colorectal cancer is the third most common in Korea and leading cause of death from cancer. Treatment outcomes for colon are steadily improving due to national health screening programs with advances diagnostic methods, surgical techniques, therapeutic agents.. The Colon Cancer Multidisciplinary (KCCM) Committee intends provide professionals who treat up-to-date, evidence-based practice guidelines improve help them make decisions that reflect their patients' values preferences. These have...
The purpose of this study was to extend the application self-expandable metallic stents by investigating their usefulness in treating colorectal obstructions caused unresectable extrinsic tumors.From January 2000 November 2005, a total 60 stenting procedures were performed, and 57 deployed 39 patients with tumors. success rate complications analyzed retrospectively.The most common etiology location obstruction advanced gastric cancer transverse colon. Technical 34 (87.2 percent). causes...
We evaluated the association between current Helicobacter pylori infection and reflux esophagitis effect of H. eradication on in a healthy screening population.A total 10,102 subjects comprehensive cohort were enrolled, 4,007 had follow-up after median 2 years. Effects estimated with odds ratios (ORs) 95% confidence intervals (CIs) using multiple logistic regression analysis. change prevalence symptoms vs. persistence.The (as classified by Los Angeles system) was 4.9% (490/10,102). Whereas...
Evaluating the risk of lymph node metastasis (LNM) is critical for determining subsequent treatments following endoscopic resection T1 colorectal cancer (CRC). This study analyzed histopathologic factors LNM in patients with CRC.
Predicting lymph node metastasis (LNM) risk is crucial in determining further treatment strategies following endoscopic resection of T1 colorectal cancer (CRC). This study aimed to establish a new prediction model for the LNM CRC patients.The development set included 833 patients with who had undergone (n=154) or surgical (n=679) at National Cancer Center. The validation 722 (n=249) (n=473) Daehang Hospital. A logistic regression was used construct model. To assess performance model,...
Abstract Background Immunomodulatory cytokines and systemic inflammatory markers are important during cancer development progression. This study investigated the association prognostic impact of cytokine profiles in colorectal (CRC). Methods Interleukin (IL)-1β, IL-6, IL-8, IL-9, IL-10, tumour necrosis factor (TNF)-α vascular endothelial growth (VEGF) serum levels were measured using multiplex bead assays CRC patients. Data on markers, such as modified Glasgow score (mGPS),...
The aims of the current study were to assess validity fecal occult blood test (FOBT) in an organized screening setting Korea and determine factors associated with FOBT validity, such as round, age group, anatomical location cancer.
Self-expanding metallic stents (SEMS) are useful palliative option and a bridge to surgery in malignant colorectal obstruction. The aim of this study was evaluate the clinical outcomes SEMS palliate obstruction.Malignant obstructive patients who underwent insertion at National Cancer Center, Korea from January 2004 June 2008 were enrolled study. Patients' characteristics, complications for retrospectively analyzed.A total 54 group 48 with CRC included as group. Obstruction left colon...
To evaluate the safety and outcomes of endoscopic piecemeal mucosal resection (EPMR) for large sessile colorectal polyps.The patients enrolled in this study were 47 with 50 polyps (diameter, 2 cm or greater) who underwent EPMR using a submucosal saline injection technique between December 2002 October 2005. All medical records, including characteristics polyps, complications, recurrences, retrospectively reviewed. The first follow-up examination was performed at 3-6 mo after initial...
The associations between alcohol consumption and cigarette smoking habits the risk for colorectal adenomatous polyps according to detailed clinical information about were assessed in a large colonoscopy-based study. study enrolled participants who visited National Cancer Center of Republic Korea cancer screening April 2007 2009. In 1,242 newly diagnosed adenoma patients 3,019 polyp-free controls, past smokers (odds ratio (OR) = 1.31, 95% confidence interval (CI): 1.04, 1.65) current (OR...
The fecal microbiota of Korean patients with inflammatory bowel disease (IBD) was investigated respect to phenotypes and taxonomic biomarkers for diagnosis prognosis IBD.Fecal samples from 70 ulcerative colitis (UC) patients, 39 Crohn's (CD) 100 healthy control individuals (HC) were collected. amplified via polymerase chain reaction sequenced using Illumina MiSeq. relationships between bacteria clinical analyzed the EzBioCloud database 16S microbiome pipeline.The alpha-diversity...
This study was designed to assess anti-Saccharomyces cerevisiae antibody positive rate in Behçet's disease and intestinal evaluate whether expression is associated with clinical findings at diagnosis course of disease.One hundred six patients disease, 30 45 healthy control subjects were included. Anti-Saccharomyces detected by indirect immunofluorescence assay. According expression, the various parameters diagnosis, cumulative relapse rates, probabilities operation...
The prevalence of irritable bowel syndrome (IBS) after excluding organic disease has not been reported in Korea.
Objective Early detection and endoscopic removal of metachronous neoplasms are important preventive strategies for patients with colorectal cancer (CRC) after curative tumor resection. We aimed to determine the incidence risk factors resection CRC . Methods retrospectively reviewed clinical data who underwent at N ational C ancer enter, K orea, from J uly 2004 2007 were followed up a mean duration 40.7 months. The developing analyzed. Results A total 1049 included in this study. follow‐up...
Rectal neuroendocrine tumors (NETs) are currently divided into L-cell and non-L-cell types. In the World Health Organization 2010 classification, defined as borderline, whereas considered to represent malignancies. To establish differential diagnostic criteria therapeutic strategy, we investigated pathologic features of rectal NETs associated with lymph node metastasis clinicopathologic significance phenotype. We analyzed 284 patients NETs. Factors, including T stage, mitosis, histologic...
