About this study

Official title: The Use Of Multiple CT Scans To Reduce Target Positioning Errors In Patients Undergoing External Beam Radiotherapy Treatment For Prostate Cancer

RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Multiple CT scans may improve the accuracy of radiation therapy for prostate cancer.

PURPOSE: Phase I trial to study the effectiveness of multiple CT scans in guiding the treatment of patients who have prostate cancer and are undergoing radiation therapy.

Read the detailed description

OBJECTIVES:

  • Compare the accuracy of radiotherapy delivery using multiple CT scans to guide patient positioning vs the standard portal image guided procedure in patients with prostate cancer undergoing external beam radiotherapy.
  • Determine the reduction in the proportion of patients with large target positioning errors using the CT-guided procedure.
  • Determine organ motion and setup errors over the course of radiotherapy in order to develop efficient clinical intervention strategies in these patients.

OUTLINE: Patients undergo radiotherapy over 9 weeks. Patients undergo a CT scan immediately prior to receiving radiotherapy on treatment days 3-8 and then weekly thereafter. On 3 different days, patients also undergo CT scan immediately after radiotherapy. If the CT scans indicate a correction that exceeds the action level currently in effect, then beginning with the next treatment, the patient's position with respect to the radiation field is adjusted.

PROJECTED ACCRUAL: A total of 25 patients will be accrued for this study within 2 years.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing computed tomography and radiation therapy in people with Prostate Cancer, run by Memorial Sloan Kettering Cancer Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Jan 2013. 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 United States. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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.

What does the primary outcome measure?

Treatment accuracy. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 18 Jan 2013.
