About

Gabriel Lebec is a radiation oncologist and researcher whose work focuses on advancing stereotactic radiosurgery and radiotherapy techniques, particularly for complex intracranial tumors. His key research areas include image-guided radiosurgery, fractionated radiation delivery, and optimizing treatment for benign and recurrent meningiomas. Lebec’s major contribution is demonstrating the safety and efficacy of five-fraction image-guided radiosurgery for primary and recurrent meningiomas—a paradigm-shifting approach that reduces the risk of symptomatic peritumoral edema compared to single-fraction treatments, especially for large or critically located tumors near cranial nerves and sinuses. His seminal 2013 paper on this topic has garnered 26 citations, establishing a foundation for fractionated radiosurgery protocols. Lebec’s work has directly influenced clinical guidelines, enabling more precise, safer radiation delivery while preserving tumor control. His research bridges the gap between technical innovation and patient-centered outcomes, making him a notable figure in the evolution of stereotactic radiosurgery. For students and researchers, Lebec’s contributions underscore the importance of fractionation in expanding radiosurgery’s applicability to challenging tumor presentations.
