Prostate Radiation Therapy or Short-Term Androgen Deprivation Therapy and Pelvic Lymph Node Radiation Therapy With or Without Prostate Radiation Therapy in Treating Patients With a Rising Prostate Specific Antigen (PSA) After Surgery for Prostate Cancer
NCT00567580 · View on ClinicalTrials.gov ↗
Study Summary
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Androgens can cause the growth of prostate cancer cells. Antihormone therapy, such as flutamide, bicalutamide, and luteinizing hormone-releasing hormone agonist, may lessen the amount of androgens made by the body. It is not yet known which regimen of radiation therapy with or without androgen-deprivation therapy is more effective for prostate cancer. PURPOSE: This randomized phase III trial is studying prostate radiation therapy to see how well it works compared with short-term androgen deprivation therapy given together with pelvic lymph node radiation therapy with or without prostate radiation therapy in treating patients with a rising PSA after surgery for prostate cancer.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00567580
The ClinicalTrials.gov registry entry for NCT00567580 describes a study currently listed as active not recruiting. It is categorized as Phase 3, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 1,792 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Radiation Therapy Oncology Group, which has 37 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Prostate Cancer appearing as the primary indexed condition, and to 4 interventions — of which LHRH agonist is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00567580 reports 20 study locations spanning 4 distinct geographic areas — top geographies include California, Arizona, Alabama. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
