About this study

Patients with oligometastatic colorectal cancer (5 metastases or less) receive a combination of systemic treatment and often local treatment, such as surgery, radiofrequency ablation and more recently stereotactic body radiotherapy. The aim of this study is to register the results and side effects of stereotactic body radiotherapy (SBRT) by means of helical tomotherapy in the treatment of oligometastatic colorectal cancer.

The trial has two cohorts. Patients in cohort I get consolidation SBRT after best response on first line chemotherapy. Patients in cohort II get SBRT when there is progression under, or no indication for (further) chemotherapy. The primary endpoint is to evaluate the metabolic complete remission rate three months after the start of radiotherapy.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Study groups in NCT00807313
Study groupRoleWhat they receive
At best responsePatients with oligometastatic colorectal cancer, who presents at best response under chemotherapy, will receive stereotactic body radiotherapy on their residual disease
No indication for chemotherapyPatients with oligometastatic colorectal cancer, who are progressive under chemotherapy or who are no candidates for (further) chemotherapy, will receive stereotactic body radiotherapy on the sites of disease.

What is being measured

Questions about this trial

What is this clinical trial studying?

An observational study of Colon Cancer and Rectal Cancer, run by Universitair Ziekenhuis Brussel 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?

The sponsor lists 8 inclusion and 0 exclusion criteria. 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 29 Dec 2020. 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.

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?

Metabolic complete remission rate (time frame: Three months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00807313, which also lists 2 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 29 Dec 2020.
