BACKGROUND AND AIMS: Primary care providers (PCPs) play a critical role in colon cancer screening by initiating referrals to gastroenterologists for colonoscopy, but little is known about their role in pre-colonoscopy bowel preparation selection and pre-colonoscopy follow-up care. This study aimed to better understand coordination of care between PCPs and gastroenterologists as well as the current availability of "open-access" screening colonoscopy. METHODS: A multiple-choice survey was developed to assess PCPs' experiences with open-access colonoscopy, their involvement in the pre-colonoscopy process, and follow-up after colonoscopy...

BACKGROUND: A family history of colorectal cancer (CRC) is an important risk factor for CRC, but more detailed data are needed to prepare effective screening guidelines. We aimed to evaluate the risk of colorectal neoplasia (CRN) among individuals with different relatives affected by CRC (the first-degree relatives [FDRs] or the second-degree relatives [SDRs] or the first cousins) and to assess the effects of family histories according to age groups (30-39, 40-49, and ≥50 years). METHODS: A cross-sectional study was performed on 98,562 asymptomatic examinees aged ≥ 30 years who underwent colonoscopy as part of a health check-up...

Small intestinal hemangioma is a rare condition that can be divided histologically into capillary, cavernous or mixed types, among which the cavernous type is the most common. Here we report a case of small intestinal cavernous hemangioma with chronic hemorrhage in 44-year-old man. The patient complained of weakness and dizziness for 2 years that aggravated 1 month before admission accompanied by intermittent melena. Laboratory tests suggest severe anemia, and computed tomography, gastroscopy and colonoscopy all revealed signs of anemia...

Behavioral economic approaches could increase uptake for colorectal cancer screening. We performed a randomized controlled trial of 2245 employees to determine whether an email containing a phone number for scheduling (control), an email with the active choice to opt in or opt out (active choice), or the active choice email plus a $100 incentive (financial incentive) increased colonoscopy completion within 3 months. Higher proportions of participants in the financial incentive group underwent screening (3.7%) than in the control (1...

Acromegaly is a rare disorder caused by chronic growth hormone (GH) hypersecretion. While diagnostic and therapeutic methods have advanced, little information exists on trends in acromegaly characteristics over time. The Liège Acromegaly Survey (LAS) database, a relational database, is designed to assess the profile of acromegaly patients at diagnosis and during long-term follow-up at multiple treatment centers. The study population consisted of 3173 acromegaly patients from ten countries; 54.5% were female...

BACKGROUND: Biomarker assays could increase the accuracy of non-invasive detection of colorectal cancer (CRC); fecal immunochemical tests (FITs) are estimated to miss 27%-47% of CRCs and 70%-80% of advanced adenomas per round of screening. We investigated the conditions under which biomarker screens would be cost-effective compared to FIT screens of average risk individuals. METHODS: We used the MISCAN-colon microsimulation model to estimate the effects of various CRC screening test characteristics on life years gained (LYG) and costsBiomarker assays could increase the accuracy of non-invasive detection of colorectal cancer (CRC); fecal immunochemical tests (FITs) are estimated to miss 27%-47% of CRCs and 70%-80% of advanced adenomas per round of screening...

Background/Aims: Colonoscopy can detect precancerous lesions, which can subsequently be removed and reduce incidences of and mortality from colorectal cancer (CRC). However, recently published data have highlighted a significant rate of CRC in patients who previously underwent colonoscopy. Among many reasons, incomplete resection has been considered as a significant contributor. However, to date, there have only been a few studies regarding incompletely resected polyps, especially advanced colorectal adenoma (ACA)...

Despite the advantages of easy applicability and cost-effectiveness, colorectal cancer mouse models based on tumor cell injection have severe limitations and do not accurately simulate tumor biology and tumor cell dissemination. Genetically engineered mouse models have been introduced to overcome these limitations; however, such models are technically demanding, especially in large organs such as the colon in which only a single tumor is desired. As a result, an immunocompetent, genetically engineered mouse model of colorectal cancer was developed which develops highly uniform tumors and can be used for tumor biology studies as well as therapeutic trials...
