RecruitingPhase 2ProcedureThe Sinai Robotic Surgery Trial in HPV-related Oropharyngeal Squamous Cell Carcinoma (SIRS 2.0 Trial)The purpose of this study is to determine whether treatment of HPV-related oropharyngeal squamous cell carcinoma in patients with undetectable postoperative HPV circulating tumor DNA (cfHPVDNA) with transoral robotic surgery (TORS) alone can result in cancer control and survival comparable to those previously reported with standard therapy. The protocol includes patients with only with low or intermediate pathologic risk factors following surgery with detectable pre-surgery cfHPVDNA and undetectable post-surgery cfHPVDNA. The hope is that with this approach, the long-term complications from chemotherapy and radiation can be reduced.
