Backgroud: (-)-Epigallocatechin-3-gallate (EGCG), the major component of green tea, is well documented to induce apoptosis and cell cycle arrest in cancer by targeting multiple signal transduction pathways. However, EGCG is extremely unstable in general culture conditions and rapidly degraded. So, to what extent EGCG or which degradation products of EGCG play a role in anti-tumor is still unknown. In this study, we evaluated the effect of different treatments of EGCG on HCT116 cells. DESIGN: MTT assay was applied to evaluated the inhibitory effect of different treatments of EGCG on HCT116 cells...

To further dissect the genetic architecture of colorectal cancer (CRC), we performed whole-genome sequencing of 1,439 cases and 720 controls, imputed discovered sequence variants and Haplotype Reference Consortium panel variants into genome-wide association study data, and tested for association in 34,869 cases and 29,051 controls. Findings were followed up in an additional 23,262 cases and 38,296 controls. We discovered a strongly protective 0.3% frequency variant signal at CHD1. In a combined meta-analysis of 125,478 individuals, we identified 40 new independent signals at P < 5 × 10-8 , bringing the number of known independent signals for CRC to ~100...

BACKGROUND: Faecal immunochemical tests (FITs) are recommended for colorectal cancer screening. Two frequently used FIT methods (FOB-Gold, Sentinel Diagnostics, Milan, Italy and OC-Sensor, Eiken Chemical, Tokyo, Japan) perform similarly in detecting advanced neoplasia (ie, colorectal cancer and advanced adenoma) at a fixed positivity cutoff for faecal haemoglobin concentration. It is unclear whether the performance of the two methods is also comparable at other thresholds. We compared the accuracy of the two assays in detecting advanced neoplasia across various thresholds...

BACKGROUND: For patients with asymptomatic, incurable, metastatic colorectal cancer, palliative, systemic treatment can be started immediately, or can be delayed until disease-related symptoms occur. How the potential survival benefit of starting palliative, systemic treatment immediately after diagnosis weighs up against the potential side effects is currently under debate, and was investigated in this review. OBJECTIVES: To assess the effects of immediate versus delayed chemotherapy, with or without targeted therapy, on overall survival, toxicity, quality of life, progression-free survival, and compliance with chemotherapy for individuals with asymptomatic, metastatic, incurable colorectal cancer...

BACKGROUND: Cardio-oncology is a recently established discipline that focuses on the management of patients with cancer who are at risk for developing cardiovascular complications as a result of their underlying oncologic treatment. In metastatic colorectal cancer (mCRC) and metastatic renal cell carcinoma (mRCC), vascular endothelial growth factor inhibitor (VEGF-i) therapy is commonly used to improve overall survival. Although these novel anticancer drugs may lead to the development of cardiotoxicity, whether early detection of cardiac dysfunction using serial echocardiography could potentially prevent the development of heart failure in this patient population requires further study...

Adenosquamous carcinoma (ASqC) is an exceedingly rare subtype of colorectal cancer without any known special guidelines for treatment. The biological behaviour and molecular background are widely unknown, although a few case studies report a worse prognosis compared to ordinary colorectal adenocarcinoma. We herein report for the first time the successful immune checkpoint inhibitor therapy in a 40-year-old patient suffering from metastasized right-sided colonic ASqC with unique molecular features, after having previously progressed under standard chemotherapy...

Importance: Colorectal cancer (CRC) incidence and mortality among individuals younger than 50 years (early-onset CRC) are increasing. The reasons for such increases are largely unknown, although the increasing prevalence of obesity may be partially responsible. Objective: To investigate prospectively the association between obesity and weight gain since early adulthood with the risk of early-onset CRC. Design, Setting, and Participants: The Nurses' Health Study II is a prospective, ongoing cohort study of US female nurses aged 25 to 42 years at study enrollment (1989)...

Background: Previously identified patient-level risk factors for chemotherapy-induced febrile neutropenia (FN) indicate several potential underlying pathogenic mechanisms, including bone marrow suppression, impaired neutrophil function, or disturbances of barrier function. This study evaluated whether additional clinical characteristics related to these pathogenic mechanisms were risk factors for FN. Patients and Methods: The study population included patients diagnosed with non-Hodgkin's lymphoma or breast, lung, colorectal, ovarian, or gastric cancer between 2000 and 2009 at Kaiser Permanente Southern California and treated with myelosuppressive chemotherapy...

BACKGROUND: Endoscopic submucosal dissection (ESD) is an effective treatment for early-colorectal cancer. Although delayed bleeding is a serious potential complication, there is no consensus on the optimal protocol to determine which cases require emergency colonoscopy. AIMS: This study aimed to assess the risk factors for delayed bleeding after ESD and evaluate the "watch and wait" strategy for delayed bleeding. The "watch and wait" strategy was used for delayed bleeding, unless the shock index was ≥ 1 and/or a moderate amount of hematochezia occurred more than five occurrences...

ᅟ: Immunochemical fecal occult blood tests (iFOBTs) are increasingly used for colorectal cancer (CRC) screening. In our preceding observational study, sensitivity for detecting advanced colorectal neoplasms by iFOBT was 70.8% among users of low-dose acetylsalicylic acid compared with 35.9% among non-users (p = 0.001), whereas there were only very small differences in specificity. In receiver operating characteristics (ROC) analyses, the area under the curve (AUC) was much higher for acetylsalicylic acid users than for non-users, with particularly strong differences in men (0...

BACKGROUND: We tested whether Medicaid expansion under the Affordable care Act was associated with increased screening for cervical, breast, and colorectal cancer among low-income adults. METHODS: We analyzed Behavioral Risk Factor Surveillance System data, identifying 2012 as preexpansion and 2016 as postexpansion (2014 was treated as a wash-out, and 2013 and 2015 had missing screening data from most states). States (including District of Columbia) either expanded Medicaid in 2014 (n=28) or not (n=18); five states that expanded after 2014 were excluded...

Cancer stem cells (CSCs) are considered to play essential roles in the process of origination, proliferation, migration, and invasion of cancer, and their properties are regulated by Wnt/β-catenin pathway. Phenethyl isothiocyanate (PEITC) is a natural product obtained from cruciferous vegetables with anticancer activities. The present study aimed to investigate the inhibitory effect and the underlying mechanisms of PEITC on colorectal CSCs. In this study, we found that PEITC can significantly reduce the size and number of colorectal cancer cell spheroids in serum-free medium...
