Radiation Therapy After Prostatectomy in Treating Patients With Stage III Prostate Cancer
A Phase 3 study testing low-LET photon therapy in people with Prostate Cancer, run by National Cancer Institute (NCI).
Trial summary
Randomized phase III trial to compare treatment with or without adjuvant radiation therapy in men with stage III prostate cancer who have had radical prostatectomy and lymphadenectomy recently. Radiation therapy uses high-energy x-rays to damage tumor cells and may be an effective treatment for prostate cancer. Read more about this study

About this study
Official title: Phase III Randomized Evaluation of Adjuvant Radiotherapy vs No Adjuvant Therapy Following Radical Prostatectomy and Pelvic Lymphadenectomy in Surgical Stage C Adenocarcinoma of the Prostate
Randomized phase III trial to compare treatment with or without adjuvant radiation therapy in men with stage III prostate cancer who have had radical prostatectomy and lymphadenectomy recently. Radiation therapy uses high-energy x-rays to damage tumor cells and may be an effective treatment for prostate cancer.
Read the detailed description
OBJECTIVES:
- Compare disease-free survival rates of patients randomly assigned to adjuvant external-beam radiotherapy vs. no adjuvant therapy following radical prostatectomy and pelvic lymphadenectomy for surgical Stage C (T3 N0 M0) adenocarcinoma of the prostate.
II. Determine the qualitative and quantitative toxicities associated with this adjuvant therapy.
OUTLINE: Randomized study. Randomization takes place when the patient is physically able to begin treatment, any time within 16 weeks after surgery.
Arm I: Radiotherapy. Irradiation of the prostatic bed using megavoltage equipment with effective photon energies of greater than 4 MV.
Arm II: No further treatment.
- Conditions
- Prostate Cancer
- Being tested
- low-LET photon therapy
- Medical subject headings

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing low-LET photon therapy in people with Prostate Cancer, run by National Cancer Institute (NCI).
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 11 Feb 2013. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00394511, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Feb 2013.
