Positron Emission Tomography in Prostate Cancer

Study Overview
=================
Brief Summary
-----------------
RATIONALE: Diagnostic procedures, such as positron emission tomography using carbon-11 acetate, may help find metastases from prostate cancer and may help predict whether prostate cancer will come back after treatment. PURPOSE: This clinical trial is studying how well positron emission tomography using carbon-11 acetate works in finding metastases and predicting recurrence in patients with prostate cancer who are at risk for recurrence after treatment.

Detailed Description
-----------------
The overall goal of this project is determination of the role of PET in patients with newly diagnosed medium- and high-risk prostate cancer in whom the standard clinical and imaging workup is negative. Thus, the incremental value of PET will be determined in this important group.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Surgery - Negative PET scan<br>If patient is candidate for surgery with curative intent or staging lymphadenectomy, he will be enrolled in the study. If patient's PET scan is negative, the patient will receive the curative therapy and be followed for recurrence. | Procedure: carbon-11 acetate PET scan<br> <br> |
| Experimental: Surgery - Positive PET scan<br>If patient is candidate for surgery with curative intent or staging lymphadenectomy, he will be enrolled in the study. If patient's PET scan is positive, the patient will receive the curative therapy and be followed for recurrence or receive alternative therapy. | Procedure: carbon-11 acetate PET scan<br> <br> |
| Active Comparator: Radiation therapy Negative or Positive PET scan<br>If patient is candidate for radiation therapy with curative intent, he will be enrolled. If PET scan is negative he will receive curative therapy and be followed for PSA recurrence. If PET scan is positive he may receive confirmatory studies and then if negative, not indicated, or refused he will receive curative therapy be followed for PSA recurrence. If PET scan is positive and received positive confirmatory studies he will receive curative therapy and followed for recurrence. | Procedure: carbon-11 acetate PET scan<br> <br> |
