In colorectal carcinogenesis, the unique molecular and genetic changes that occur within cells result in specific CRC phenotypes. The involvement of the long non-coding RNA, HOTAIR, in cancer development, progression, and metastasis is well established. Various studies have reported on the contribution of HOTAIR to cancer pathogenesis. Therefore, we selected four HOTAIR polymorphisms (rs7958904G>C, rs1899663G>T, rs4759314A>G, and rs920778T>C) to evaluate the association of each variant with CRC

BACKGROUND & AIMS: The optimal systemic chemotherapy for combined hepatocellular-cholangiocarcinoma (cHCC-CCA) has not yet been defined. The definition and classification of cHCC-CCA has changed recently in the 5th edition of WHO classification. We reviewed the pathological findings with the new classification and analysed the efficacy of systemic chemotherapy in patients with unresectable/metastatic cHCC-CCA. METHODS: Among 254 patients with histologically confirmed cHCC-CCA from 1999 to 2015 i

This study was conducted to identify the composition and diversity of the microbiome in tissues of pancreatic cancer and to determine its role. First, extracellular vesicles (EVs) were obtained from the paired tumor and normal tissues, and 16s rRNA gene sequencing was performed. We identified the microbiomes, compared the diversity between groups, and found that Tepidimonas was more abundant in tumors. Second, larger tumors resulted in lower levels of Leuconostoc and Sutterella, and increased ly

Because non-anthracycline-based chemotherapy with l-asparaginase has improved survival outcomes in patients with extranodal natural killer/T-cell lymphoma (ENKTL), the incidence of central nerve system (CNS) relapse can be different when compared with that in previous reports. In this research, we sought to identify the incidence of and predictors for CNS relapse and to evaluate the necessity of CNS prophylaxis with intermediate-dose methotrexate (ID-MTX). The records of 399 patients in the trai

PURPOSE: The aim of this study is to evaluate the safety and efficacy of ex vivo activated and expanded natural killer (NK) cell therapy (SNK01) plus pembrolizumab in a randomized phase I/IIa clinical trial. MATERIALS AND METHODS: Overall, 18 patients with advanced non-small cell lung cancer (NSCLC) and a programmed death ligand 1 tumor proportion score of 1% or greater who had a history of failed frontline platinum-based therapy were randomized (2:1) to receive pembrolizumab every 3 weeks +/- 6

BACKGROUND: Patients with mucinous gastric carcinoma (MGC) usually have a poor prognosis, largely due to the advanced stage of disease. In this study, we evaluated the effects of c-MYC amplification on tumor stage and disease-specific survival of 128 patients with MGC and compared the results with those of 302 patients with non-mucinous gastric carcinoma (non-MGC). PATIENTS AND METHODS: Two-color fluorescence in situ hybridization (FISH) for c-MYC was performed on 430 GC samples. Real-time quant

BACKGROUND: Polymorphisms in angiogenesis-related genes and metabolic syndrome (MetS) risk factors play important roles in cancer development. Moreover, recent studies have reported associations between a number of 3'-UTR polymorphisms and a variety of cancers. The aim of this study was to investigate the associations of three VEGF 3'-UTR polymorphisms (1451C > T [rs3025040], 1612G > A [rs10434], and 1725G > A [rs3025053]) and MetS with colorectal cancer (CRC) susceptibility in Koreans. METHODS:

The plasminogen activator inhibitor-1 (PAI-1) is expressed in many cancer cell types and modulates cancer growth, invasion, and angiogenesis. The present study investigated the association between five PAI-1 gene polymorphisms and colorectal cancer (CRC) risk. Five PAI-1 polymorphisms (−844G > A [rs2227631], −675 4G > 5G [rs1799889], +43G > A [rs6092], +9785G > A [rs2227694], and +11053T > G [rs7242]) were genotyped using a polymerase chain reaction-restriction fragment length pol

PURPOSE: This study aimed to evaluate the survivals of patients with metastatic or recurrent gastric cancer (MRGC) over a period of 16 years and to investigate the recent changes in chemotherapy patterns. MATERIALS AND METHODS: A total of 5,384 patients who received chemotherapy for MRGC between 2000 and 2015 were analyzed. The analysis focused on a comparison of the first-line chemotherapy between four periods: 2000-2003 (period 1), 2004-2007 (period 2), 2008-2011 (period 3), and 2012-2015 (per

Arcanobacterium haemolyticum was isolated from the blood cultures of a previously healthy 37-year-old man who met all the criteria of Lemierre syndrome, including a primary oropharyngeal infection, evidence of thrombophlebitis of the internal jugular vein, and metastatic infections. To the best of our knowledge, this is the first case of Lemierre syndrome caused by A. haemolyticum in Korea and shows that A. haemolyticum alone can cause Lemierre syndrome.

Colorectal cancer (CRC) is the third most common type of cancer and the second leading cause of cancer-related mortality in Western countries. Polymorphisms in one-carbon metabolism and angiogenesis-related genes have been shown to play important roles in tumor development, progression, and metastasis for many cancers, including CRC. Moreover, recent studies have reported that polymorphisms in specific microRNA (miRNA)-binding regions, which are located in the 3′-untranslated region (UTR) of miR
