NCT03465982

Brief Summary

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.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age \>18 years
  • cT3/4N0/+M0 confirmed on CT-scan, MRI (stratification for T3a-b-c-d) 3
  • Tumor starting from the distal or medium rectum (even those crossing the peritoneal reflection at distal margin, within 15 cm from the anal margin)
  • Histologically-proven adenocarcinoma of the rectum
  • Eligible for a resective surgery with TME (low anterior resection, intersphincteric resection, abdominoperineal resection)
  • Eligible for resection by minimally-invasive surgery (standard or robotic-assisted laparoscopic procedure, all robotic systems will be accepted)
  • Eligible for chemoradiation treatment
  • Able to give written informed consent
  • Capable of completing required questionnaires at time of consent (provided questionnaires are available in a language spoke fluently by the participant)

You may not qualify if:

  • Metastatic disease
  • Squamous carcinoma of the anal canal
  • Synchronous colorectal tumors requiring multi-segment surgical resection (n.b. a benign lesion within the resection field in addition to the main cancer would not exclude a patient)
  • History of psychiatric or addictive disorder or other medical condition that, in the opinion of the investigator, would preclude the patient from meeting the trial requirements
  • Pregnancy
  • Unable to complete neoadjuvant treatment
  • Unable to give free informed consent
  • Previous radiation treatment on the pelvis
  • Inflammatory bowel disease
  • Hereditary colorectal disease
  • Previous tumors other than non-melanoma skin cancer, papillary or follicular thyroid cancer
  • Participation in another rectal cancer clinical trial relating to the topic of this trial
