This systematic review examined factors associated with overuse of colorectal cancer (CRC) screening. The authors searched MEDLINE and EMBASE from January 1998 to March 2017. Studies were included if they were written in English, contained original data, involved a US population, and examined factors potentially associated with overuse of CRC screening. Paired reviewers independently screened abstracts, assessed quality, and extracted data. In 8 studies, the associations between patient factors, including age, sex, race, and number of comorbidities, were tested and were inconsistently associated with CRC screening overuse...

BACKGROUND AND AIMS: There are few prospective data about the use of surveillance colonoscopy and the risk of recurrent neoplasia in first degree relatives (FDRs) of colorectal cancer (CRC) patients. We examined the use and yield of surveillance colonoscopy in a population-based screening program (Trentino, Italy) METHODS: 1252 FDRs have been included in this study. We calculated compliance (percentage of FDRs who underwent surveillance colonoscopy among those eligible), appropriateness of colonoscopy (appropriate if performed within 6 months of the guidelines recommended interval) and diagnostic yield for neoplasia...

Health care disparities among people with schizophrenia is a global concern. Our previous study revealed cancer screening rates in Japanese people with schizophrenia lower than rates of approximately 40% of the general population. However, that study was based on self-reports, which can be inaccurate, and rates did not differentiate the types of cancer screening provider (i.e., municipal screening, collective opportunistic screening, and individual opportunistic screening). This study aimed to investigate records-based cancer screening rates, focusing on participation rates of people with schizophrenia who are subject to municipal cancer screening programs...

BACKGROUND: The incidence and mortality rate of colorectal cancer (CRC) have increased dramatically over the past 3 decades in China due to changes in lifestyle factors. Early detection and treatment guidelines for asymptomatic cases have shown to improve CRC control in developed countries. In response to these challenges, the Shanghai Municipal Government launched a community-based CRC screening program in 2012. MATERIALS AND METHODS: Free initial screening, inclusive of immunochemical fecal occult blood and risk assessment (questionnaire), was provided by community health centers in Shanghai...

Background: Recognition of rare molecular subgroups is a challenge for precision oncology and may lead to tissue-agnostic approval of targeted agents. Here we aimed to comprehensively characterize the clinical, pathological and molecular landscape of RET rearranged metastatic colorectal cancer (mCRC). Patients and methods: In this case series, we compared clinical, pathological and molecular characteristics of 24 RET rearranged mCRC patients with those of a control group of 291 patients with RET negative tumors...

The aim of this study was to estimate the contribution of the effect of age, period, and birth cohort on mortality from colorectal cancer. The study analyzed data on deaths from this cancer in individuals over 35 years of age in Rio de Janeiro State, Brazil, obtained from the Mortality Information System (SIM) from 1980 to 2014. Mortality rates were calculated by gender and age bracket. The effect of age, period, and birth cohort was estimated by the method that uses estimable functions: deviations, curves, and drift in the Epi library of the R software...

Organoids have extensive applications in many fields ranging from modelling human development and disease, personalised medicine, drug screening, etc. Moreover, in the last few years, several studies have evaluated the capacity of organoids as transplantation sources for therapeutic approaches and regenerative medicine. Nevertheless, depending on the origin of the cells and anatomical complications, an organoid transplant may make tissue regeneration difficult. However, some essential aspects of organoids including the morphological alterations and the growth pattern of the matched tumour and their healthy derived organoids have received less attention...

Despite treatment of patients with metastatic colorectal cancer (mCRC) with bevacizumab plus chemotherapy, response rates are modest and there are no biomarkers available that will predict response. The aim of this study was to assess if markers associated with three interconnected cancer-associated biological processes, specifically angiogenesis, inflammation and oxidative damage, could stratify the survival outcome of this cohort. Levels of angiogenesis, inflammation and oxidative damage markers were assessed in pre-bevacizumab resected tumour and serum samples of mCRC patients by dual immunofluorescence, immunohistochemistry and ELISA...

BACKGROUND: Colorectal cancer (CRC) is the third most common type of cancer and the second leading cause of cancer death in the United States. About one in three adults in the United States is not getting the CRC screening as recommended. Internal medicine residents are deficient in CRC screening knowledge. OBJECTIVE: The objective of our study was to assess the improvement in internal medicine residents' CRC screening knowledge via a pilot approach using a smartphone app...

Early detection of colorectal cancer (CRC) is key to reducing associated mortality. Despite the importance of early detection, approximately 40% of individuals in the United States between the ages of 50-75 have never been screened for CRC. The low compliance with colonoscopy and fecal-based screening may be addressed with a non-invasive alternative such as a blood-based test. We describe here the analytical validation of a multiplexed blood-based assay that measures the plasma concentrations of 15 proteins to assess advanced adenoma (AA) and CRC risk in symptomatic patients...

MicroRNAs (miRNAs), endogenous small noncoding RNAs (ncRNAs), play crucial roles in cancer development. Many studies have demonstrated that miRNAs can serve as diagnostic and therapeutic biomarkers for malignancies. Additionally, single nucleotide polymorphisms (SNPs) located in miRNA functional regions have been reported to be involved in cancer susceptibility. In this study, we investigated the associations between SNPs located in miRNA functional regions and colorectal cancer (CRC) susceptibility. We systematically screened all candidate miRNAs and their SNPs and then evaluated the relationships between the SNPs and CRC susceptibility in a Han Chinese population including 878 patients with CRC and 884 controls...

With an increasing trend of patients with young-onset colorectal cancer (CRC), risks of second primary cancers (SPCs) among them become a concerning issue. We aimed to define the detailed risk and site-distributed patterns of SPCs in young CRC individuals (age ≤50). A population-based cohort were identified from the Surveillance, Epidemiology, and End Results database between 1973 and 2013. Standardized incidence ratios (SIRs) and absolute excess risk (AER) were calculated to assess the risk for SPCs compared with the general population...

Comprehensive cancer centers are an important community resource for cancer prevention education in their catchment areas. Colorectal cancer remains one of the most commonly diagnosed cancers in the United States, making prevention a priority. Colorectal cancer prevention targets include lifestyle modifications that are influenced by cultural norms, such as diet change, physical activity and screening behavior. Cancer centers must tailor prevention efforts to multiethnic catchment areas. This paper describes the development and feasibility of a comprehensive cancer center's approach to community-based colorectal cancer prevention in Houston, Texas, specifically targeting Hispanic and Asian populations...

Background: Colonoscopy is widely used in the Veterans Affairs (VA) health care system for colorectal cancer (CRC) prevention, but its effect on CRC mortality is unknown. Objective: To determine whether colonoscopy is associated with decreased CRC mortality in veterans and whether its effect differs by anatomical location of CRC. Design: Case-control study. Setting: VA-Medicare administrative data. Participants: Case patients were veterans aged 52 years or older who were diagnosed with CRC between 2002 and 2008 and died of the disease by the end of 2010...

Esophageal atresia (EA) is one of the most common congenital digestive malformations and requires surgical correction early in life. Dedicated centers have reported survival rates up to 95%. The most frequent comorbidities after EA repair are dysphagia (72%) and gastroesophageal reflux (GER) (67%). Chronic GER after EA repair might lead to mucosal damage, esophageal stricturing, Barrett's esophagus and eventually esophageal adenocarcinoma. Several long-term follow-up studies found an increased risk of Barrett's esophagus and esophageal carcinoma in EA patients, both at a relatively young age...

Background: Although people living with HIV or AIDS (PLWHA) are at higher risk for many cancers, breast, prostate, and colorectal cancer rates are lower in this patient population. Because these tumors are often screen-detected, these inverse associations could be driven by HIV-related differences in utilization of cancer screening. Methods: We ascertained incident breast, prostate, and colorectal cancer in PLWHA using data from the HIV/AIDS Cancer Match Study (1996-2012)...

Lynch syndrome is the most common hereditary cancer syndrome, the most common cause of heritable colorectal cancer, and the only known heritable cause of endometrial cancer. Other cancers associated with Lynch syndrome include cancers of the ovary, stomach, urothelial tract, and small bowel, and less frequently, cancers of the brain, biliary tract, pancreas, and prostate. The oncogenic tendency of Lynch syndrome stems from a set of genomic alterations of mismatch repair proteins. Defunct mismatch repair proteins cause unusually high instability of regions of the genome called microsatellites...
