Who can take part

AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults who had a small, early colorectal cancer removed by endoscopic submucosal dissection and whose removed tissue showed a high risk of spread to the lymph nodes.

Age
18 years or older
Sex
All sexes can join.
Disease stage
Early (superficial, T1) colorectal cancer removed by endoscopy. The removed tissue must show at least one high-risk sign: invasion depth of 1000 microns or more, tumor budding grade 2 or higher, or cancer cells in lymph or blood vessels.
Earlier treatment
Must have had submucosal dissection (endoscopic removal) and be included in the French FECCo registry since September 2019.

Main reasons for not taking part

  • Crohn's disease or ulcerative colitis
  • Familial adenomatous polyposis or a genetic risk of colorectal cancer
  • Colon tumor of stage T2 or higher
  • Not included in the FECCo registry
  • Has objected after reading the information notice

Who can take part

  • Adult patient (18 years or older)
  • Presumed diagnosis of localized superficial colorectal cancer (T1) during endoscopy using the Conecct classification, confirmed by subsequent histopathological analysis
  • Patient included in the French Colorectal ESD Cohort in Experts Centers (FECCo registry) since September 2019 for submucosal dissection
  • Histological analysis of the resection specimen revealing a superficial colorectal adenocarcinoma with high risk of lymphatic recurrence, defined by at least one of the following criteria: submucosal invasion depth ≥ 1000 microns, tumor budding grade ≥ 2, presence of lymphatic and/or vascular emboli

Who cannot take part

  • History of Crohn's disease (ICD-10: K50) or ulcerative colitis (ICD-10: K51)
  • History of familial adenomatous polyposis and/or genetic predisposition to colorectal cancer (ICD-10: D12.6+0/1/2/4/5 and 6)
  • Malignant tumor of the colon staged ≥ T2
  • Patients not included in the FECCo registry
  • Documented objection through the non-opposition form following review of the information notice

About the trial

What the trial wants to find out

Colorectal cancer is a common and leading cause of death. Pre-cancerous lesions, as well as some so-called superficial cancers, can be resected via endoscopy. The technique chosen in the case of extensive lesions or superficial cancer is submucosal dissection. This technique helps avoid surgery, which has a higher morbidity and mortality (especially due to the non-preservation of the organ).

The group in the trial

  • Surgery, Radiochimiotherapy, Surveillance

    Patients who underwent surgery, radiochimiotherapy or nothing.

    Treatment: Surgery, Radiochimiotherapy
