About

Aaron R. Hansen is a clinician-researcher specializing in head and neck oncology, with a particular focus on oropharyngeal squamous cell carcinoma (OPC) and the integration of transoral robotic surgery (TORS) with radiotherapy de-intensification strategies. His work sits at the intersection of surgical innovation, radiation oncology, and health economics, addressing one of the field's most pressing questions: how to optimize treatment outcomes while minimizing toxicity and cost. Hansen's most influential contribution—a cost-effectiveness analysis comparing radiation therapy to TORS for OPC (46 citations)—provided critical economic evidence to guide treatment selection in an era of competing modalities. His ongoing leadership of the FIND trial, a landmark prospective study examining TORS-guided radiotherapy volume reduction in unknown primary head and neck cancer, reflects his commitment to translating surgical precision into meaningful reductions in treatment-related morbidity. This work has helped establish a framework for identifying occult oropharyngeal primaries and safely narrowing radiotherapy fields. Beyond head and neck oncology, Hansen has contributed to urologic oncology through robotic retroperitoneal lymph node dissection for testicular cancer. With over 115 cumulative citations, his research continues to shape multidisciplinary cancer care and inspire the next generation of oncology clinicians pursuing evidence-based surgical innovation.
