Type 2 diabetes mellitus (T2DM) is associated with greater risk for colorectal cancer (CRC). The age of onset of T2DM is decreasing worldwide. An increased CRC risk in young T2DM patients could be relevant for the age at which to initiate CRC screening. We report on CRC risk in T2DM patients with attention to age of diagnosis. We used pharmacy data (from 1998 to 2010) from the PHARMO Database Network linked to the Eindhoven Cancer Registry. Multivariable time-dependent Cox regression analyses were conducted to calculate hazard ratios (HR) for developing CRC comparing T2DM with non-T2DM...

BACKGROUND: Colorectal cancer (CRC) diagnosed at <50 years is predominantly located in the distal colon and rectum. Little is known about which lesion subtypes may serve as CRC precursors in young adults. The aim of this work was to document the prevalence and histological subtype of lesions seen in patients aged <50 years, and any associated clinical features. METHODS: An audit of the colonoscopy database at The Queen Elizabeth Hospital in Adelaide, South Australia over a 12-month period was undertaken...

Approximately 90% of all cancer deaths arise from the metastatic dissemination of primary tumors. Metastasis is the most lethal attribute of colorectal cancer. New data regarding the molecules contributing to the metastatic phenotype, the pathways they control and the genes they regulate are very important for understanding the processes of metastasis prognosis and prevention in the clinic. The purpose of this study was to investigate the role of T-LAK cell-originated protein kinase (TOPK) in the promotion of colorectal cancer metastasis...

OBJECTIVE: Post-colonoscopy colorectal cancer (PCCRC), a cancer occurring within a short interval of a colonoscopy, might be partly explained as missed or incompletely resected lesions. Associated risk factors are age, sex, comorbidity, cancer location, and colonoscopy volume. There is a gap in the knowledge of prevalence of PCCRC and the impact of different risk factors in Sweden. METHODS: This is a retrospective population-based observational cohort study of the colonoscopies performed on adults during the years 2001-2010 that were identified from Swedish health registers...

Diets rich in fruits and vegetables may lower colorectal cancer risk. In particular, a number of in vitro and in vivo studies demonstrated that cruciferous vegetables and their active compounds elicit chemopreventive potency through multiple mechanisms. However, it is relatively unexplored whether these vegetables modulate the risk of cancer development through epigenetic mechanisms including noncoding RNAs. Therefore, the objective of the present review is to report and discuss existing evidence with regards to modulation of microRNAs (miRNAs), one variety of noncoding RNAs, by cruciferous vegetables and their chemo-preventive effects against colorectal cancers...

Background Tanibirumab is a fully human monoclonal antibody to vascular endothelial growth factor receptor 2 (VEGFR-2). We conducted a first-in-human phase I study of tanibirumab in patients with solid tumors refractory to standard chemotherapy. Primary endpoints were evaluating safety, pharmacokinetics (PKs), estimating maximum-tolerated dose (MTD) and recommended phase II dose (RP2D). Methods We designed our study to escalate tanibirumab at 9 different dose levels with a 3 + 3 method and tanibirumab (1-28 mg/kg) was administered intravenously on D1, 8, 15 in 28-day courses...

Colorectal cancer (CRC) is the third leading cancer diagnosed globally and an important cause of cancer-related mortality. Of interest, while we have witnessed a declining incidence trend over the past few decades in the older population, incidence rates for adolescents and young adults have been increasing steadily. Several factors may well explain this apparent epidemic in the young, namely a lack of routine screening and emerging lifestyle issues such as obesity, lack of exercise, and dietary factors. It is known that both environmental and genetic factors can increase the likelihood of developing CRC...

BACKGROUND: Racial disparities in incidence of colorectal cancer (CRC) exist. In Hispanics, CRC was the second most commonly diagnosed cancer in 2012. METHODS: We abstracted the national estimates for Hispanics/Whites with CRC using the SEER database between 2000 and 2010. Trends in incidence, mortality, gender and stage of disease were analyzed for early-onset (age<50; EO - young) and late-onset (age>50; LO - old) cases. RESULTS: The overall incidence of CRC increased by 48% in Hispanics...

BACKGROUND: New Zealand has among the highest rates of colorectal cancer in the world and is an unscreened population. The aim of this study was to determine the trends in incidence and tumour location in the New Zealand population before the introduction of national colorectal cancer screening. METHODS: Data were obtained from the national cancer registry and linked to population data from 1995 to 2012. Incidence rates for colorectal cancer by sex, age (less than 50 years, 50-79 years, 80 years or more) and location (proximal colon, distal colon and rectum) were assessed by linear regression...

Background: Colorectal cancer (CRC) incidence in the United States is declining rapidly overall but, curiously, is increasing among young adults. Age-specific and birth cohort patterns can provide etiologic clues, but have not been recently examined. Methods: CRC incidence trends in Surveillance, Epidemiology, and End Results areas from 1974 to 2013 (n = 490 305) were analyzed by five-year age group and birth cohort using incidence rate ratios (IRRs) and age-period-cohort modeling...

Cancer stage at diagnosis is the most important prognostic factor for survival. We conducted a nationwide, population-based cohort study to investigate cancer stage distribution in immigrants compared to the host population of Norway. All patients recorded in the Cancer Registry of Norway in 1990-2014 were included (17 709 immigrants and 431 936 Norwegians). Individual level sociodemographic data was obtained from Statistics Norway. Ordered logistic regression was used to estimate if immigrants were diagnosed with cancer at a more advanced stage than Norwegians...

Participation rates in colorectal cancer (CRC) screening programmes using faecal occult blood tests (FOBTs) are low. Nonparticipation is commonly attributed to psychosocial factors, but some medical conditions also prevent screening. These barriers might be partially overcome if a blood test for CRC screening was available. This study determined whether people who had always declined screening by FOBT would participate if offered a blood test. An audit of registrants within a personalized CRC screening programme was undertaken to determine the reasons for regular nonparticipation in FOBT...

Green cincau (Premna oblongifolia Merr) is an Indonesian food plant with a high dietary fibre content. Research has shown that dietary fibre mixtures may be more beneficial for colorectal cancer prevention than a single dietary fibre type. The aim of this study was to investigate the effects of green cincau extract on short chain fatty acid (SCFA) production in anaerobic batch cultures inoculated with human faecal slurries and to compare these to results obtained using different dietary fibre types (pectin, inulin, and cellulose), singly and in combination...

INTRODUCTION: Despite the known benefits of colorectal cancer (CRC) screening, rural areas have consistently reported lower screening rates than their urban counterparts. Alternative healthcare delivery models, such as accountable care organizations (ACOs), have the potential to increase CRC rates through collaboration among healthcare providers with the aim of improving quality and decreasing cost. However, researchers have not sufficiently explored how this innovative model could influence the promotion of cancer screening...

Methionine (Met) is involved in one-carbon de novo nucleotide synthesis and is an essential amino acid for cell survival. The impact of lactate calcium salt (CaLa) on the Met metabolism was investigated to evaluate the enhanced antitumor effect of methotrexate (MTX) on colorectal cancer (CRC) cells. Met dependency relating to homocysteine (Hcy) and betaine was investigated in human CRC cells (HCT-116 and HT-29) using a viability assay and liquid chromatography-mass spectrometry. Expression of betaine transporter-1 (BGT-1) following treatment with MTX alone or with CaLa was determined by Western blot...

Purpose MG1102 is a potent inhibitor of angiogenesis in both in vitro and in vivo models. The purpose of the study was to investigate the safety and tolerability, pharmacokinetic (PK) profile, and preliminary antitumor efficacy of MG1102. Methods Patients with refractory solid tumors were eligible. Each patient received 1 dose of MG1102 followed by a 6-day rest period, during which they underwent PK assessments and safety monitoring. If the initial dose was tolerated, the patient continued with the 21-day treatment of MG1102 (5 days on, 2 days off for 3 weeks)...
