Gene Mutation “Hotspots” Linked to Better Breast Cancer Outcomes

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
