  AI-assisted colonoscopy improves adenoma detection by 22% in meta-analysis of 46 trials

  A systematic review of 46 randomized controlled trials involving 37,012 participants found that AI-assisted colonoscopy was associated with a 22% relative increase in adenoma detection rate (RR = 1.22, 95% CI = 1.17-1.27) and a 22% relative increase in polyp detection rate compared to conventional colonoscopy, though the authors noted very low certainty of evidence and lack of long-term outcome data.

  Multiomic profiling identifies FAK, PDK, and proteasome as therapeutic targets in RAS-mutant MSS colorectal cancer

  Analysis of approximately 2,000 tumor samples and 195,246 single cells revealed that focal adhesion kinase, phosphoinositide-dependent kinase, and proteasome inhibition combined with MEK blockade showed activity in patient-derived models of RAS-mutant microsatellite-stable colorectal cancer.

  Chemotherapy-induced apoptotic cell overload drives formation of tumor-suppressive multinucleated giant cells

  Researchers found that excessive apoptotic cell burden after neoadjuvant chemotherapy activates the TREM2/TYROBP-MAPK pathway, promoting macrophage fusion into multinucleated giant cells that inhibit tumor growth and reshape the immune microenvironment in preclinical models. (Cell Death Dis)

  Female colorectal cancer survivors more likely to use dietary supplements throughout disease trajectory

  A prospective cohort study of 1,934 colorectal cancer survivors found that female and higher educated participants were more likely to use dietary supplements, with 43% reporting use at diagnosis and 53% at five years post-diagnosis. (Support Care Cancer)

This week's research spans detection technology, molecular profiling of treatment-resistant subtypes, and the expanding picture of early-onset disease.
