Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • 18 years or older
  • Patients with primary rectal cancer without distant metastases who underwent CRT and show clinical complete response or very good response: Clinical complete response (ycT0N0) or very good response (ycT1-2N0) after pre-operative chemoradiation will be determined clinically (digital rectal examination, endoscopy), radiologically (contrast-enhanced-MRI) and pathologically (biopsy)
  • Informed consent and capability of giving informed consent
  • Comprehension of the alternative strategies and the concept of unknown risks are clear to the patient (in other words that the patient understands the experimental base of the study).

Who cannot join

  • Recurrent rectal cancer.
  • Distant metastasis.
  • Unable or unwilling to comply to the intensive follow-up schedule.
  • Contra-indications for MRI. If MRI is not possible because of contra-indications (e.g. pacemaker) we will exclude patients. MRI is crucial for response evaluation and follow-up and can not be omitted in patients that follow the alternative strategies ('wait-and-see policy' or TEM).

About this study

Official title: Minimal Invasive Treatment for Patients With Good Response to Chemoradiation With Selection and Follow-up by MRI: a Single Arm Phase-II Feasibility Study in Rectal Cancer

The high proportion of complete and good responders with modern chemoradiation and the improvement in magnetic resonance (MR)-imaging techniques have stimulated a renewed interest to the question whether in patients with complete or good response the overall benefits of a 'wait-and-see policy' or transanal endoscopic microsurgery (TEM) combined with intensive follow-up may outweigh the benefits associated with conventional surgery (total mesorectal excision (TME)or abdominoperineal resection (APR)). On the one hand, less invasive strategies will expose subjects to more diagnostic procedures and possibly a slightly higher risk of local failure and the need for salvage surgery. On the other hand, mortality and morbidity associated with radical surgery (e.g. anastomotic leakage, relaparotomy, wound and pelvic infection, chronic wound healing disturbances, abscess, colostomy, faecal or urinary incontinence and sexual dysfunction) can be avoided. The investigators believe that wait-and-see policy for complete responders and TEM for good responders after chemoradiation is a feasible alternative to standard surgery, provided these patients are intensively followed.

Questions about this trial

What is this clinical trial studying?

A study testing Wait&see or TEM with intensive follow-up in people with Locally Advanced Rectal Cancer, run by Maastricht University Medical Center at 2 sites in Netherlands.

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 4 inclusion and 4 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 24 Mar 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Netherlands. 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?

Local recurrence (time frame: 2 and 5 years). 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 NCT00939666, 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 24 Mar 2017.
