New approach to bowel cancer analysis could lead to better prognosis for patients

Researchers from Queen’s University have demonstrated how a precise integration of the results of both pathological and molecular analysis of tumour and normal tissue from the bowel can ensure a correct interpretation of the data, providing a more accurate result that can underpin better treatment options for bowel cancer patients. The paper, ‘Epithelial-to-mesenchymal transition signature assessment in colorectal cancer quantifies tumour stromal content rather than true transition,’ in the journal The Journal of Pathology.

Ten-year follow-up after negative colonoscopies linked to lower colorectal cancer risk

Ten years after a negative colonoscopy, Kaiser Permanente members had 46 percent lower risk of being diagnosed with and were 88 percent less likely to die from colorectal cancer compared with those who did not undergo colorectal cancer screening, according to a study, ‘Long-term Risk of Colorectal Cancer and Related Deaths After a Colonoscopy With Normal Findings’, published in JAMA Internal Medicine.

Researchers develop personalised tool for inherited colorectal cancer syndrome

An international team of researchers led by Huntsman Cancer Institute (HCI) at the University of Utah (U of U) has developed, calibrated, and validated a novel tool for identifying the genetic changes in Lynch syndrome genes that are likely to be responsible for causing symptoms of the disease. The paper, ‘A functional assay–based procedure to classify mismatch repair gene variants in Lynch syndrome,’ was published in Genetics in Medicine

Loss of two genes drives a deadly form of colorectal cancer, revealing potential treatment

Scientists from Sanford Burnham Prebys Medical Discovery Institute (SBP), in collaboration with clinicians from Scripps Clinic, have identified that the loss of two genes drives the formation of serrated colorectal cancer, yielding potential biomarkers. The research has also identified a combination treatment that has treated the cancer in mice. The paper, ‘Simultaneous Loss of Both Atypical Protein Kinase C Genes in the Intestinal Epithelium Drives Serrated Intestinal Cancer by Impairing Immunosurveillance,’ was published in the journal Immunity.

Tailored lifestyle feedback during colorectal cancer screening improved health behaviours

A programme that provided individually tailored lifestyle recommendations for patients undergoing screening for colorectal cancer helped encourage healthy behaviour, according to results of a study’ Improving Cancer Preventive Behaviors: A Randomized Trial of Tailored Lifestyle Feedback in Colorectal Cancer Screening,’ published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.
