ERHS 551B - Radiation Biology Principles for Medicine: Principles of Radiation Oncology

  • 2 credits

Application of basic radiation biology to the clinical application of radiation therapy. Radiation sensitivity and tolerance is evaluated based on normal tissue architecture and kinetics. The mechanisms of acute and late radiation effects are elucidated. The impact of time, dose, and fractionation on tumor control and radiation effects are clarified and related to established and newer treatment modalities, including combination therapies and emerging technologies.

Dr. LaRue is Professor of Cancer Radiotherapy. Dr. LaRue’s translational research employs naturally occurring tumors in companion animals to develop new combination radiotherapy protocols and better understand the biology of the cancer. Understanding the mechanisms of radiation-induced tissue damage as a by-product of radiation therapy is a primary interest. Dr. LaRue is currently working on a project to develop a model of radiation-induced erectile dysfunction, and evaluating radiation protocols that might mitigate non-target tissue damage in radiation oncology therapies of the prostate.
