Bladder and Bone Effects of Pelvic Radiation Therapy in Childhood Cancer Survivors

The aim of this study is to measure and evaluate the effects of pelvic external beam radiation therapy (EBRT) on lower urinary tract (LUT) function and bone mineralization. The overarching hypothesis is that patients who received EBRT to the pelvis will have an increased rate of LUT dysfunction and osteoporosis even when controlled for chemotherapeutic exposures, using patients with similar chemotherapy regimens as controls. Between these two groups, the team expect to observe significant differences in both patient-reported outcomes and direct measures of LUT function.
