About this study

Official title: Timing to Minimally Invasive Surgery After Neoadjuvant Chemoradiotherapy for Rectal Cancer: a Multicenter Randomised Controlled Trial

The trial is a multicenter, prospective, randomized controlled, unblinded, parallel-group trial comparing standard and delayed surgery after neoadjuvant chemoradiotherapy for the curative treatment of rectal cancer. Three-hundred and thirty-two patients will be randomized on an equal basis to either robotic-assisted/standard laparoscopic rectal cancer surgery after 8 weeks or robotic-assisted/standard laparoscopic rectal cancer surgery after 12 weeks. The recruiting interval will be of 5 years and the follow-up period will end 5 years after the last patient is randomized.

Read the detailed description

PURPOSE

To demonstrate if delayed timing of surgery after neoadjuvant chemoradiotherapy actually affects pathological complete response (pCR) and reflects on disease-free survival (DFS) and overall survival (OS) rather than standard timing. Eight weeks are the current standard interval to surgery after neoadjuvant treatment, while 12 weeks represent the "minimum" longer time interval to determine further tumor modifications and the "a priori" choice to avoid hypothetical surgical detrimental effect (postoperative complications related to radiation therapy).

Primary Endpoint

  • pCR

Secondary Endpoints

  • DFS
  • OS
  • QoL (quality of Life)

Site Eligibility

The trial is a multicenter collaboration, involving all those centers able to provide the standard of cure for locally advanced rectal cancer. All the involved centers have to respect the following criteria:

  • Site able to perform robotic-assisted and standard laparoscopic rectal cancer surgery and TaTME (transanal total mesorectal excision)
  • Site able to provide a preoperative work up according to the work up criteria specified in this trial
  • Site able to provide standard neoadjuvant treatment, both chemo and radiation therapy, according to the criteria specified in this trial
  • Predicted capability to recruit a minimum of 15 patients per year to the trial.

Randomization will take place after consent is obtained and after patients have completed their baseline patient reported questionnaires. Patient consent and randomization will take place as close to the date of start of the neoadjuvant treatment as possible and must be no more than 30 days prior to planned treatment.

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 9 inclusion and 12 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: looking for participants now, as of the sponsor's last update on 16 Apr 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 14 sites in Italy. 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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Igor Monsellato, MD (+390131206506, igor.monsellato@ospedale.al.it), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

pathologic complete response (pCR) (time frame: 8-12 weeks). 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 NCT03465982, which also lists 6 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 Apr 2024.
