Bone Mineral Density Test + MRI or CT + Blood Test

During routine visits, a magnetic resonance imaging (MRI) scan or a computed tomography (CT) scan.

Blood (about 1 tablespoon) will be drawn to test for bone turnover.

CT or MRI + Blood Test

Kathleen Schmeler, MD

The goal of this study is to estimate how often pelvic fractures occur in women treated with radiation therapy for either newly diagnosed or recurrent cervical, endometrial, or vaginal cancer. The study will also estimate the changes in bone mineral density and the changes in the blood that relate to "bone turnover". High bone turnover can weaken bones and make you more likely to break a bone.

If you agree to take part in this study, the following tests and procedures will be performed before radiation therapy:

* 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 may have either a magnetic resonance imaging (MRI) scan or a computed tomography (CT) scan of the pelvis as part of your standard of care. A PET scan may be done if your doctor thinks it is necessary. 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.
* Blood (about 2 to 3 teaspoons) will be drawn for tests to measure the level of vitamin D, calcium, phosphorus, and parathyroid hormone (PTH).
* 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 and/or alcohol.

At 4 weeks after start of radiation therapy, blood (about 2 to 3 teaspoons) will be drawn to test for bone turnover.

At 3 months, 1 year, and 2 years after you complete radiation:

* You will have a bone mineral density test.
* You may have either an MRI or CT scan of the pelvis as part of your standard of care. A PET scan may be done if your doctor thinks it is necessary. 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 2 tablespoons) will be drawn for tests to measure the level of vitamin D and to test for bone turnover.

Length of Study:

You will be off study 2 years after you complete radiation.

After 2 years and for up to 5 years, results of bone density tests or scans of the pelvis that you have outside of this study will be collected.

This is an investigational study.

Up to 300 women will take part in the study. All will be enrolled at MD Anderson.

Participants received oral enzalutamide at 160 mg once daily for 24 weeks. Participants who had clinical benefit at Week 25 could continue to receive enzalutamide until disease progression, objective or clinical, or occurrence of an unacceptable toxicity, at the discretion of the investigator.

Use Central Contact

To evaluate the effect of enzalutamide on prostate specific antigen (PSA) level in men with prostate cancer.

A Study to Test if Enzalutamide is Effective and Safe in Prostate Cancer Patients Who Have Never Had Hormone Therapy

A Phase 2, Open-label, Single-arm, Efficacy and Safety Study of Enzalutamide (MDV3100) in Patients With Hormone-naïve Prostate Cancer

A PSA response was defined as a decline from Baseline in PSA level of 80% or greater. Blood samples for PSA were collected and analyzed at a central laboratory. Participants with an unknown or missing response or who discontinued prior to week 25 for any reason were treated as non-responders.

Each adverse event (AE) was assessed by the investigator for causal relationship to the study drug; those deemed possibly or probably related to study drug are reported as drug regimen related AEs (DRRAEs).

A serious adverse event (SAE) was defined as any untoward medical occurrence that at any dose:

* Resulted in death
* Was life-threatening
* Resulted in persistent or significant disability/incapacity
* Resulted in congenital anomaly or birth defect
* Required inpatient hospitalization or led to prolongation of hospitalization
* Other medically important events.

A PSA response was defined as a decline from baseline in PSA level of 80% or greater. Blood samples for PSA were collected and analyzed at a central laboratory. Participants with an unknown or missing response or who discontinued prior to week 49, week 97 or week 169 for any reason were treated as non-responders.

Participants with unknown or missing PSA results at week 25 or who discontinued prior to week 25 were considered non-responders at week 25. Participants with unknown or missing PSA results at week 49, week 97 or week 169 were considered non-responders.

Participants with unknown or missing PSA results at week 25 or who discontinued prior to Week 25 were considered non-responders at Week 25. Participants with unknown or missing PSA results at week 49, 97 and 169 were considered non-responders.

Participants with unknown or missing PSA results at week 25 or who discontinued prior to week 25 were considered non-responders at week 25. Participants with unknown or missing PSA results at week 49, 97 or 169 were considered non-responders.

The maximum decline from Baseline in PSA was calculated as the largest reduction from Baseline in PSA level that occurred at any point after treatment start up to week 25 and up to and including the assessment made at the safety follow-up visit, divided by the PSA Baseline value and multiplied by 100, i.e., the maximum percent change from baseline.

Time to PSA response (PSA decline ≥ 80% from Baseline) is defined as the time interval from the first study drug dose to the first date a decline from Baseline in PSA level of 80% or greater was recorded. Time to response was estimated using the Kaplan-Meier method.

Time to PSA decline ≥ 90% is defined as the time interval from the first study drug dose to the first date a decline from Baseline in PSA level of 90% or greater was recorded. Time to PSA decline ≥ 90% was estimated using the Kaplan-Meier method.

Time to PSA ≤ 4 ng/ml is defined as the time interval from the first study drug dose to the first date a decline in PSA to a result of 4 ng/ml or below was recorded. Time to PSA ≤ 4 ng/ml was estimated using the Kaplan-Meier method.

Time to PSA ≤ 0.1 ng/ml is defined as the time interval from the first study drug dose to the first date a decline in PSA to a result of 0.1 ng/ml or below was recorded.

Time to PSA ≤ 0.1 ng/ml was estimated using the Kaplan-Meier method.

Time to PSA progression is defined as the time interval from the first study drug dose to the first date of PSA progression. PSA progression is defined as a ≥ 25% increase in PSA with an absolute increase of ≥ 2 ng/mL above the nadir unless the PSA next measurement(s), if available, does not confirm the PSA progression.

PSA doubling time was to be calculated from the slope estimated from a linear regression of the natural log of PSA fitted on time, if the slope was positive. Since the slope was negative for all participants, PSA doubling time could not be calculated.

Duration of Prostate Cancer

Unknown

A system of grading prostate cancer tissue based on how it looks under a microscope. Gleason scores range from 2 to 10 and indicate how likely it is that a tumor will spread. A low Gleason score means the cancer tissue is similar to normal prostate tissue and the tumor is less likely to spread; a high Gleason score means the cancer tissue is very different from normal and the tumor is more likely to spread.

Total Gleason Score at Initial Diagnosis

TX: Primary tumor cannot be assessed

T0: No evidence of primary tumor

T1: Tumor neither palpable or visible by imaging

T2: Tumor confined within the prostate

T3: Tumor extends through the prostatic capsule

T4: Tumor is fixed or invades adjacent structures

Clinical Tumor Stage (T) at Initial Diagnosis

NX: Regional lymph nodes were not assessed

N0: No regional lymph node metastasis

N1: Metastasis in regional lymph node(s)
