Christopher Ryan Kelsey


Professor of Radiation Oncology

Clinical trials that are currently enrolling patients include a study investigating lower doses of radiation therapy for patients with diffuse large B-cell lymphoma, with the goal of maintaining excellent tumor control but decreasing the risk of long-term side effects of treatment.

I also have an interest in genetic determinants of radiation sensitivity, predictors of local recurrence after surgery for lung cancer, radiation-induced lung injury, and the role of radiation therapy in advanced (stage III-IV) diffuse large B-cell lymphoma and Hodgkin lymphoma.
