About

Dr. Alexander Gregor is a leading thoracic surgeon and researcher whose work centers on advancing the diagnosis and treatment of lung cancer through minimally invasive techniques. His primary research areas include bronchoscopic navigation, robotic bronchoscopy, and optimized surgical approaches for early-stage non-small cell lung cancer (NSCLC). Dr. Gregor has made significant contributions to the field by evaluating and refining technologies that improve the accuracy of tissue diagnosis for pulmonary nodules. His highly cited 2019 paper on bronchoscopic navigation and tissue diagnosis (42 citations) established a framework for integrating new navigation tools into clinical practice. In another influential 2019 work (24 citations), he critically examined the adoption of minimally invasive surgical (MIS) approaches for NSCLC, highlighting the ongoing debate between traditional and modern techniques despite MIS becoming the favored standard. Dr. Gregor’s more recent narrative review (2021) explores the role of emerging technologies like navi- and robo-bronchoscopy in accessing lung nodules, addressing the growing challenge posed by increased detection through screening programs. His research is pivotal in shaping safer, more effective interventions that balance diagnostic yield with patient risk, making him a key voice in the evolution of thoracic oncology.
