Phase angle as a prognostic nutritional marker for survival in nasopharyngeal carcinoma patients undergoing chemoradiotherapy: a prospective cohort study (opens in new tab)

BackgroundConventional nutritional indicators have limitations in predicting outcomes for nasopharyngeal carcinoma (NPC) patients undergoing chemoradiotherapy. Phase angle (PA), a bioelectrical impedance-derived measure of cellular integrity, has emerged as a prognostic marker in various malignancies but remains understudied in NPC. This study investigated whether PA provides superior prognostic information for overall survival (OS) compared to conventional indicators.MethodsIn this prospecti...
