Genetic phenomenon associated with low tumor invasiveness and longer patient survival could inform prognosis and help identify patients who would best respond to immunotherapy and other treatments —

Kataegis is a recently discovered phenomenon in which multiple mutations cluster in a few hotspots in a genome. The anomaly was previously found in some cancers, but it has been unclear what role kataegis plays in tumor development and patient outcomes. Using a database of human tumor genomic data, researchers at the University of California San Diego School of Medicine and Moores Cancer Center have discovered that kataegis is actually a positive marker in breast cancer — patients with these mutation hotspots have less invasive tumors and better prognoses. … Read the Full Story from the UC San Diego News Center
