Impact of PET Scan on the Curative Strategy of Colo-rectal Cancers : A Randomized Study
A study testing semi-annual systematic PET-TDM and PET-TDM for current indication in people with Colorectal Cancer, run by Assistance Publique - Hôpitaux de Paris at 1 site in France.
Trial summary
The risk of recurrence in stage III and IV of colorectal cancers (CRC) is high during the three years following the tumoral resection with curative aim. Therefore, a prolonged follow-up and an intense monitoring are recommended to detect these recurrences precociously. Read more about this study

About this study
The risk of recurrence in stage III and IV of colorectal cancers (CRC) is high during the three years following the tumoral resection with curative aim. Therefore, a prolonged follow-up and an intense monitoring are recommended to detect these recurrences precociously. Nevertheless, current consensual morphological and biological examinations are not very contributory, of difficult interpretation and expensive. The metabolic imagery in tomoscintigraphy by emission of positron coupled with the scanner, called PET-TDM, allows to identify more specifically recurrences, analyzes the whole body, detects hepatic metastasis more precociously and give some benefice for early diagnosis of lymph nodes recurrence. The principle purpose of this study is to evaluate if the systematic follow-up per PET-TDM allows detecting more often recurrences accessible to a curative surgery. We make the hypothesis that the systematic practice of PET- tomodensitometry (TDM) during the follow-up of CRC allows to decrease non curative recurrences appearance during the 3 years follow-up after a curative surgery.
Read the detailed description
Patients will be randomized in two groups: one (PET-TDM group) including a semi-annual systematic PET-TDM during usual follow-up (M6, M12, M18, M24, M30 and M36 after initial surgery) and the second (control group) in which one PET-TDM will be realized only for current indication (high isolated markers or before a metastasis curative resection) during usual follow-up. Will be included patients with a high risk of recurrence of a colorectal tumor N+ or M+ completely removed (R0 or R1) or tumor stage 4, no regional lymph node metastasis, no distant metastasis (T4N0M0) operated in emergency (tumoral perforation).
Patients will be followed-up during 3 years since the date of initial surgery. Conventional follow-up will be performed by consensual recommendations for all the patients. In the case of detecting a recurrence, the adapted treatment (surgery or chemotherapy or both) with curative aim will be implemented and the follow-up will be carried out in its term or death. In the case of non curable recurrence, the follow-up will be carried out in its term or death, and the PET-TDM will not be realised any more.

Questions about this trial
What is this clinical trial studying?
A study testing semi-annual systematic PET-TDM and PET-TDM for current indication in people with Colorectal Cancer, run by Assistance Publique - Hôpitaux de Paris at 1 site in France.
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 11 inclusion and 10 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 18 Mar 2016. 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 France. 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?
Percentage of patients with a non removable recurrence (time frame: at the end of the study). 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 NCT00624260, which also lists 1 linked publication.
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 Mar 2016; AzTrials last refreshed its copy on 8 Nov 2026.
