Support for fecal testing in familial colorectal cancer screening

“In our study, repeat FIT screening detected all colorectal cancers in asymptomatic first-degree relatives of patients with colorectal cancer,” said lead study authors Enrique Quintero, MD, PhD, and Marta Carrillo, MD, from Hospital Universitario de Canarias, Tenerife, Spain. “These findings suggest that FIT screening should potentially be considered for familial screening, especially in populations where colonoscopy capacity is limited and/or compliance with colonoscopy is a concern.” Researchers conducted a prospective randomized trial to compare the efficacy of repeated FITs and colonoscopy in detecting advanced tumors in family members of patients with colorectal cancer. The study included 1,918 first-degree relatives of patients with colorectal cancer, who were randomly split into two groups to receive either a single colonoscopy examination or three FITs — one a year for three years…

New factor to control oncogene-induced senescence discovered

The researchers who participated in this international research are: Marta Cascante and Vitaly Selivanov, from the Department of Biochemistry and Molecular Biology of the Faculty of Biology of the UB and the Institute of Biomedicine of the University of Barcelona (IBUB), affiliated to the campus of International excellence Barcelona Knowledge Campus (BKC) ; Liang Zheng and Eyal Gottlieb, from Beatson Institute for Cancer Research (Scotland), and Joanna Kaplon and Daniel S. Peeper, from the Netherlands Cancer Institute, among other experts. Cellular senescence: a ‘brake’ to cell division Cellular senescence, formally described more than four decades ago by Paul Moorhead and Leonard Hayflick, is a tumour suppression mechanism which limits cell’s ability to proliferate. This process works as a ‘brake’ for tumour genesis and can be an answer to several factors (oncogene, oxidative stress, telomere alterations, etc.) Professor Marta Cascante, head of the Consolidated Research Group on Integrative Systems Biology, Metabolomics and Cancer of the UB honoured with the ICREA Academia Award 2010, explains that "as a response to an oncogene mutation, cell can activate its protection mechanisms and get into a phase so-called ‘oncogene-induced senescence’ which acts as a key tumour suppressive mechanism. …
