Evaluation of Bone Density and Pelvic Fractures in Women Undergoing Definitive Pelvic Radiation Therapy for Cervical, Endometrial or Vaginal Cancer
If you agree to take part in this study, the following tests and procedures will be
performed before radiation therapy, and again 3 months, 1 year, and 2 years after you
- You will have a bone mineral density test. A bone mineral density test measures bone
loss over time, identifies osteoporosis (a disease of the bones that causes them to be
weak and easily breakable) or the risk for developing osteoporosis, and checks your
risk for fractures. During the test, you will lie on a cushioned table while a
mechanical arm-like device will pass over your body. This device will not touch you.
- During your routine visits, you will have either a magnetic resonance imaging (MRI)
scan or a computed tomography (CT) scan of the pelvis as part of your standard of care.
The type of scan used will be decided by your doctor. These scans will be reviewed by
the research staff of this study to determine your response to therapy, determine if
your cancer has returned, and to look for broken bones.
- Blood (about 1 tablespoon) will be drawn to test for bone turnover.
- Before you start treatment, blood (about 2 to 3 teaspoons) will be drawn for tests to
measure the level of vitamin D, calcium, phosphorus, and parathyroid hormone (PTH).
When you join the study, researchers will collect information from your medical record. This
information will include your medical history, your ethnicity, if you have had any bone
fractures, if you have a history of bone fractures in your family, and your use of tobacco
Length of Study:
You will be off study 2 years after you complete radiation.
This is an investigational study. Up to 300 women will take part in the study. All will be
enrolled at M. D. Anderson.
