Circulating cell free tumour derived nucleic acids are becoming recognised as clinically significant and extremely useful biomarkers for detection of cancer and for monitoring the progression of targeted drug therapy and immunotherapy. Screening programmes for colorectal cancer in Europe use the Fetal Immunochemical Test (FIT) test as a primary screener. FIT+ patients are referred to immediate colonoscopy and the positive predictive value (PPV) is usually 25%. In this article, we report a study employing the ColoScape assay panel to detect mutations in the APC, KRAS, BRAF and CTNNB1 genes, in order to collect preliminary performance indicators and plan a future, larger population study...

Background and study aims  Endoscopic full-thickness resection (eFTR) allows en-bloc and transmural resection of colorectal lesions for which other advanced endoscopic techniques are unsuitable. We present our experience with a novel "clip first, cut later" eFTR-device and evaluate its indications, efficacy and safety. Patients and methods  From July 2015 through October 2017, 51 eFTR-procedures were performed in 48 patients. Technical success and R0-resection rates were prospectively recorded and retrospectively analyzed...

Many normal tissues undergo age-related drift in DNA methylation, providing a quantitative measure of tissue age. Here we identify and validate 781 CpG-islands (CGI) that undergo significant methylomic drift in 232 normal colorectal tissues and show that these CGI continue to drift in neoplasia while retaining significant correlations across samples. However, compared with normal colon, this drift advanced (~3-4 fold) faster in neoplasia, consistent with increased cell proliferation during neoplastic progression...

Objective: Fecal transferrin has been suggested as a complementary or even superior marker for early detection of colorectal cancer (CRC) besides fecal hemoglobin. We aimed to evaluate both markers individually and in combination in a large cohort of participants of screening colonoscopy. Methods: Precolonoscopy stool samples were obtained from participants of screening colonoscopy and frozen at -80℃ until blinded analysis, using a dual-quantitative fecal immunochemical test (FIT) for hemoglobin and transferrin...

BACKGROUND: Colorectal cancer (CRC) is largely preventable with routine screening and surveillance colonoscopy; however, interval cancers arising from precancerous lesions missed by standard colonoscopy (SC) still occur. Increased adenoma detection rate (ADR) has been found to be inversely associated with interval cancers. The G-EYE device comprises a reusable balloon integrated at the distal tip of a standard colonoscope, which flattens haustral folds, centralizes the colonoscope's optics and reduces bowel slippage...

Background: Fecal immunochemical tests (FITs) are widely used and recommended for colorectal cancer (CRC) screening. Fecal hemoglobin (Hb) may degrade with long transport durations and high ambient temperatures, potentially reducing sensitivity to detect CRC and its precursors. This study aimed at investigating the impact of temperatures and sample travel times on diagnostic performance of a quantitative FIT for detection of advanced neoplasms (AN, CRC, or advanced adenoma). Methods: Participants of screening colonoscopy in south-western Germany conducted a quantitative FIT prior to bowel preparation between February 2012 and June 2016...

OBJECTIVE: Endoscopic technique is in many cases the technique of choice for the removal of pituitary adenomas. Extended endoscopic approaches make possible to remove lesions with suprasellar, parasellar extension and with fibrous consistency. We tried to identify some characteristics that might point to the adoption of an expanded approach in the preoperative phase. METHODS: We considered 66 consecutive cases treated for pituitary macroadenomas. All patients underwent to preoperative MRI and CT, as well as to postoperative MRI...

BACKGROUND AND AIMS: Current post-polypectomy surveillance interval guidelines do not discriminate between 1-2 diminutive (1-5mm) and small (6-9mm) non-advanced adenomas. This study compared the risk for metachronous advanced lesions in these groups. METHODS: Patients with 1-2 diminutive, non-advanced adenomas and no further advanced lesions, and patients with no polyps at baseline colonoscopy were retrospectively analyzed to determine the rate of metachronous advanced lesions...

Introduction: 52% of faecal immunohistochemistry test (FIT)-positive clients in the Irish National Colorectal Cancer Screening Programme (BowelScreen) have adenomatous polyps identified at colonoscopy in round 1. Although it is known that advanced adenomas and cancers cause an elevated FIT, it is not known if small (<5 mm) adenomas cause a positive FIT. Aims: Determine if removal of small polyps in an FIT-based colorectal cancer (CRC) screening programme is associated with a negative FIT on follow-up...

Background: Colorectal cancer (CRC) is the second most common cancer in Germany. Screening colonoscopies are considered an effective tool for early detection and prevention of CRC and are recommended in Germany for citizens over the age of 55. To increase the participation rate for screening colonoscopies, an invitation procedure was initiated in parts of Germany for patients between the ages of 55 and 75 who had never undergone a screening colonoscopy before. Methods: We examined the number of participating patients before, during, and after the invitation procedure and compared the number of the participating patients who received a cover letter with the participating patients from the control group...
