About

K. Roger Cohen is a leading head and neck surgical oncologist whose work has fundamentally reshaped the management of oropharyngeal cancer. His primary research focuses on minimally invasive surgical techniques, particularly transoral robotic surgery (TORS), and the critical goal of de-escalating treatment to reduce patient morbidity without compromising oncologic outcomes. Cohen’s most impactful contribution is his landmark 2012 prospective study demonstrating that TORS alone—without adjuvant radiation or chemotherapy—could achieve excellent local control for select patients with oropharyngeal squamous cell carcinoma. This seminal work, cited over 228 times, challenged the prevailing paradigm of multimodality therapy and provided the foundational evidence for a single-modality surgical approach. By showing that a precise robotic resection could be curative on its own, Cohen helped pioneer a shift toward more personalized, function-preserving care. His research has been instrumental in sparing countless patients the long-term toxicities of combined treatment. A respected academic surgeon, Cohen’s work continues to influence clinical guidelines and inspire further investigation into de-escalation strategies, cementing his legacy as a transformative figure in head and neck oncology.
