Stereotactic Body Radiation Therapy in Treating Patients With Localized Prostate Cancer That Have Undergone Surgery
NCT03541850 · View on ClinicalTrials.gov ↗
Study Summary
This phase II trial studies how well stereotactic body radiation therapy works in treating patients with prostate cancer that has not spread to other parts of the body and have undergone surgery. Stereotactic body radiation therapy is a specialized radiation therapy that sends x-rays directly to the tumor using smaller doses over several days and may cause less damage to normal tissue.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT03541850
The ClinicalTrials.gov registry entry for NCT03541850 describes a study currently listed as active not recruiting. It is categorized as Phase 2, 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 92 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Jonsson Comprehensive Cancer Center, which has 442 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 5 conditions, with PSA Progression appearing as the primary indexed condition, and to 3 interventions — of which Quality-of-Life Assessment 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: NCT03541850 reports 2 study locations spanning 1 distinct geographic area — top geographies include California. 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.
