About
Dr. Geoffrey A. Geiger is a leading radiation oncologist whose research focuses on de-intensifying treatment for HPV-related oropharyngeal cancer, aiming to reduce long-term toxicities while preserving excellent oncologic outcomes. His most impactful contribution is the landmark AVOID trial (2019, 167 citations), a Phase 2 study demonstrating that omitting radiation to the resected primary tumor bed after transoral robotic surgery is safe and effective for select patients with HPV-positive disease. This work has helped shift clinical practice toward more personalized, less morbid treatment paradigms. Dr. Geiger has also investigated risk factors for contralateral neck disease in tonsil cancer, refining patient selection for unilateral neck radiation to minimize unnecessary exposure. His research consistently addresses the critical balance between treatment efficacy and quality of life, making him a key voice in the de-escalation movement. Through his publications and clinical trials, Dr. Geiger continues to shape evidence-based approaches that spare patients from overtreatment, advancing the field of head and neck oncology with a focus on precision and patient-centered care.
