Researchers identify genetic abnormalities that drive invasiveness in head and neck cancer A multi-institutional team of researchers has identified both the genetic abnormalities that drive pre-cancer cells into becoming an invasive type of head and neck cancer and patients who are least likely to respond to immunotherapy. Through a series of surprises, we followed clues that focused more and more tightly on specific genetic imbalances and their role in the effects of specific immune components in tumor development."
