PURPOSE In the treatment of non–small-cell lung cancer (NSCLC) with a driver mutation, role anti–PD-(L)1 antibody after tyrosine kinase inhibitor (TKI) remains unclear. This randomized, open-label, multicenter, phase III study evaluates efficacy atezolizumab plus bevacizumab, paclitaxel, and carboplatin (ABCP ) in EGFR- or ALK-rearranged translocated NSCLC upon progression on TKI therapy. MATERIALS AND METHODS We compared clinical ABCP followed by maintenance therapy bevacizumab pemetrexed...
Intra-class correlation coefficients (ICCs) provide a statistical means of testing the reliability. However, their interpretation is not well documented in orthopedic field. The purpose this study was to investigate use ICCs literature and demonstrate pitfalls regarding use.First, articles that used were retrieved from Pubmed database, journal demography, ICC models concurrent statistics evaluated. Second, reliability test performed on three common physical examinations cerebral palsy,...
Propofol-based total intravenous anesthesia (TIVA) has been reported to improve long-term outcome following cancer surgery, when compared with inhalation agents. However, such investigational reports are still controversial, and no studies have conducted in relation non-small cell lung (NSCLC) surgery. The present study aimed compare the favorable effects of TIVA versus agents on recurrence-free survival overall after curative resection NSCLC. This retrospective cohort examined medical...
Abstract Background Liver function tests (LFTs) can be affected by many factors and the proposed effects of coffee on LFT require a comprehensive evaluation. The aim this study was to elucidate whether drinking coffee, smoking, or alcohol have independent LFTs in Korean health-check examinees. Methods We used responses 500 examinees, who had participated self-administered questionnaire survey about drinking, smoking habits. Results Coffee consumption closely related male gender, high body...
Purpose To investigate the association of genetic and environmental factors, their interactions in Korean patients with exudative age-related macular degeneration (AMD). Methods A total 314 robustly characterized AMD patients, including 111 PCV (polypoidal choroidal vasculopathy) 154 typical neovascularization (CNV), 395 control subjects without any evidence were enrolled. Full ophthalmologic examinations fluorescein angiography (FA), indocyanine green (ICG) optical coherence tomography...
Abstract Background The operative link on gastric atrophy (OLGA) and intestinal metaplasia (OLGIM) stages have been suggested for risk estimation of cancer (GC). However, usefulness OLGA/OLGIM systems in diffuse type GC was not investigated so far. aims this study were to evaluate the estimating according Lauren's classification investigate interaction among factors. Materials methods evaluated 1398 (765 control 633 patients) who prospectively enrolled Seoul National University Bundang...

This study investigated the association of 3 components body composition (sarcopenia, intramuscular fat deposition and visceral adiposity) with overall or recurrence-free survival hepatocellular carcinoma (HCC) patients who underwent curative hepatic resection.One hundred sixty newly diagnosed surgically treated HCC were retrospectively enrolled from 2003 to 2011. Three items measured using 3rd lumbar level image preoperative computed tomography (CT): psoas muscle index (PMI), attenuation...
The authors aimed to assess whether the prevalence of intracranial aneurysms in patients with meningiomas was higher than that a healthy population.The performed hospital-based case-control study 300 newly diagnosed and 900 age- sex-matched controls without history brain tumors evaluate any associations between meningiomas. Unconditional multivariate logistic regression models were used for comparisons.Intracranial identified 23 (7.7%) 24 (2.7%; p < 0.001). There significant association (OR...
Background Chronic rhinosinusitis with nasal polyps (CRSwNP) is a multidimensional disease. In this study, we performed an unsupervised cluster analysis of CRSwNP using routinely available clinical markers. Methods We conducted retrospective review patients treated endoscopic sinus surgery due to medically intractable bilateral from 2009 2017. Unsupervised was patient's features, including age, peripheral blood eosinophil, tissue eosinophilia, Lund‐Mackay computed tomography (CT) scores,...
Although several studies have investigated the outcomes after distal hamstring lengthening (DHL), no study has undertaken an approach that included all or most of important factors could influence results. This was performed to evaluate DHL and analyze improvement serial change in knee motion surgery patients with cerebral palsy (CP), using a linear mixed model (LMM).The 314 ambulatory CP (594 limbs) spsastic diplegia who were followed up undergoing as part single-event multilevel underwent...
If we use only volumetry for measuring lymphedema, could underdiagnose lymphedema with characteristics of biomechanical changes without definite volume change, especially in the medial forearm.In total, 158 breast cancer patients participated this study. Arm was measured by water displacement volumetry, and segmental volumes were calculated from circumferences using truncated cone method. Subcutaneous ultrasound echogenicities assessed on side upper arm forearm both arms graded subcutaneous...
BACKGROUND Hidroacanthoma simplex (HAS) is an uncommon eccrine neoplasm of the skin. It a benign neoplasm, but some cases malignant change were reported in literature. OBJECTIVE To describe rare case porocarcinoma relatively short period from pre-existing HAS on abdomen. METHODS Wide local excision was performed this neoplasm. RESULTS There no recurrence for 72 months after wide excision. CONCLUSION We recommend early and careful attention because its potential change.
Abstract Background The aim of this study was to investigate the trends atrophy and intestinal metaplasia (IM) in 2002 subjects without significant gastroduodenal diseases. Materials Methods A total were prospectively enrolled divided into three periods (2003‐2007, 2008‐2012, 2013‐2018). Trends H pylori atrophy/IM scored by Updated Sydney System analyzed according sex, multivariate logistic analysis performed for risk factors atrophy/IM. Results ‐negative ‐positive 1220 (61.0%) 782 (38.0%),...
Abstract Background & Aims Coffee consumption is inversely related to the risk of cirrhosis or hepatocellular carcinoma ( HCC ). However, protective effect coffee drinking against was not established in HBV ‐prevalent region. To elucidate relationship between lifetime and development under consideration replication status . Methods A hospital‐based case–control study performed 1364 subjects. total 258 patients, 480 health‐check examinees (control 1, HCE ) 626 patients with chronic liver...
Genital odor is an uncommon condition characterized by offensive and malodorous smell in the genital area. Although etiology of foul multifactorial, important cause sweat secretion decomposition components bacteria. Different methods are effective reducing body secondary to bromhidrosis. Conservative only act for a short period time, more invasive surgical carry risk complications or inapplicable region.A patient with localized hair bearing area was treated botulinum toxin A.Botulinum A...
Purpose To retrospectively compare ultrasound (US) and CT as the preoperative first-line imaging modality in terms of negative appendectomy rate (NAR) appendiceal perforation (APR) adolescents adults with suspected appendicitis. Methods We included 2,030 patients 11 sites who underwent following US (n = 102) or 1,928). Propensity-score (PS) adjusted matched comparisons were conducted. Matching was performed 1:1 1:3 ratios. Secondary analyses by adding to PS model. Results The unadjusted NAR...
Although alpha-fetoprotein (AFP) is the most widely used biomarker in hepatocellular carcinoma (HCC) surveillance, disease activity may also increase AFP levels chronic hepatitis B (CHB). Since nucleos(t)ide analog (NA) therapy reduce not only HBV viral loads and transaminase but falsely elevated CHB, we tried to determine whether exposure NA influences performance selective application can optimize of testing CHB during HCC surveillance. A retrospective cohort 6,453 patients who received...
