About this study

Official title: PHASE III STUDY OF POST-OPERATIVE EXTERNAL RADIOTHERAPY IN PATHOLOGICAL STAGE T3 N0 PROSTATIC CARCINOMA

RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells and may be an effective treatment for prostate cancer.

PURPOSE: Randomized phase III trial to compare radiation therapy with no further treatment in treating patients with stage III prostate cancer following radical prostatectomy.

Read the detailed description

OBJECTIVES:

  • Compare local recurrence rates, acute and late morbidity, overall survival, disease-free survival, and cancer-related survival of patients with pT3 pN0 adenocarcinoma of the prostate randomized following radical prostatectomy to postoperative conventional pelvic irradiation (60 Gy) vs no further treatment until relapse.
  • Better define the selective pathologic indications for radiotherapy in patients with pT3 pN0 disease.

OUTLINE: This is a randomized study.

  • Arm I: Patients undergo radiotherapy daily, 5 days a week, for 5 weeks, followed by boost radiotherapy for 1-1.4 weeks.
  • Arm II: Patients are observed. Local relapse is treated with conventional pelvic radiotherapy.

Patients are followed every 3 months during the first postoperative year, every 6 months until the fifth year, and annually thereafter.

PROJECTED ACCRUAL: A total of 1000 patients will be accrued for this study within 7.5 years.

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 European Organisation for Research and Treatment of Cancer - EORTC at 1 site in Belgium.

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 16 Oct 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Belgium. Whether a site is taking part right now should be confirmed with that site. See every site.

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 NCT00002511, which also lists 15 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 16 Oct 2012.
