About this trial

Randomized head-to-head comparison trial among patients who have undergone incomplete endoscopic resection of early colon cancer to evaluate the benefits, harms and burdens, as well as the ecological footprint and cost-effectiveness of endoscopic full thickness resection (eFTR), a minimally invasive endoscopic treatment with a colonoscope, as compared to standard-of-care surgery.

Co-primary endpoints are

* Rate of severe adverse events classified as grade III to V according to the Clavien Dindo classification within 30-days after study treatment * CRC recurrence or sign of lymph nodes or distant metastases at 3 years after randomization comparing the two treatment groups (eFTR versus surgery).

Eligibility criteria

Qualifiers

Men and women, age 40 years or older with endoscopic removal (snare or forceps polypectomy; endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) with R1 (resection margin <0.1mm23,40) or Rx resection margins of colon cancer (location proximal to the rectum (12 cm or more from the anal verge))

No contraindication for colon surgery as deemed by the multidisciplinary tumor board (MTB) at the participating centre

Absence of the following histopathological tumor features: poor differentiation, lymphovascular invasion, tumor budding grade B2-B3.

No sign of disease beyond stage T1N0M0 on standard-of-care computed tomography imaging of the thorax, abdomen and pelvis41 and clinical evaluation
