Risk Adapted De-Intensification of Radio-Chemotherapy for Favorable Prognosis Oropharyngeal Squamous Cell Carcinoma Based on HPV Subtype and Plasma Circulating Free HPV DNA Level and Clearance Rate
University of Florida
Summary
This study builds on the results of several prior studies that we have been involved with to test the hypothesis that Risk-Adapted De-Intensification of Radiation Therapy and chemotherapy based on HPV subtype, plasma circulating free HPV DNA (cfHPV DNA) level, and cfHPV DNA clearance rate produces Local-Regional Control rates that are similar to what has been achieved with more aggressive therapy in patients with Favorable Prognosis Oropharyngeal Squamous Cell Carcinoma (OPSCC).
