Pelvic Radiation and Normal Tissue Toxicity.

Radiation is a component of treatment for many pelvic malignancies, most often originating in the gynecologic, gastrointestinal, and genitourinary systems. Therefore, the management of acute and long-term side effects is an important part of practice as a radiation oncologist, and limiting morbidity is a primary goal. Toxicities vary and are dependent on treatment techniques. Advances in radiation delivery, imaging, and knowledge of underlying biologic determinants of radiation-induced normal tissue toxicity can guide treatment of acute and long-term side effects from pelvic radiation.
