About

Keith Sigel is a leading clinical researcher in thoracic oncology, with a focus on optimizing treatment outcomes for older adults with lung cancer. His work bridges the gap between surgical innovation and real-world patient care, particularly through comparative effectiveness research. Sigel is best known for his landmark 2019 study on robotic-assisted surgery for resectable lung cancer in older patients, which has garnered 78 citations and reshaped clinical decision-making by demonstrating that robotic approaches can offer meaningful benefits in this vulnerable population. Beyond this, his research portfolio spans cancer epidemiology, health services research, and the intersection of aging and cancer care. Sigel’s contributions are distinguished by their direct impact on clinical guidelines and surgical practice, helping to personalize treatment for patients who are often underrepresented in clinical trials. His work is widely cited by surgeons, oncologists, and health policy researchers, reflecting its influence on both academic discourse and patient outcomes. Through rigorous methodology and a patient-centered lens, Sigel continues to advance the evidence base for thoracic cancer care in an aging population.
