Welcome to the website of the Dutch T1 Colorectal Cancer (CRC) Working Group The Dutch T1 CRC Working group Group is a collaboration between gastroenterologists, surgeons and pathologists. With this multidisciplinary multicenter collaboration we aim to perform high-quality research concerning the detection, diagnosis, treatment and surveillance of T1 CRC in order to increase common knowledge and awareness and decrease the number patients that will be referred for surgery without any benefit. Please feel free to contact us if you have any questions regarding the working group, want to participate in our working group or want to collaborate in future trials.

4th T1 CRC Symposium- SAVE THE DATE
Webinar updated guideline
On June 10th, 2025, we held a webinar about the main changes in guideline section 5.2: the treatment strategy following local excision of T1 and T2 colon tumours, illustrated through a case-based discussion.
You can watch it again under the section: colorectal cancer guideline
CROSSROADS
The CROSSROADS project is a national initiative aimed at reducing unnecessary completion surgery after local excision of pT1-T2 colon carcinomas with a limited risk of lymph node metastases.
The project consists of two prospective cohorts monitoring the recently changed colorectal cancer (CRC) guideline and a historical cohort extracted from the DICA 2.0 project.
The historical cohort serves as a comparison group for the prospective studies and will provide insights into recurrences.
Key information obtained from the historical data will be used to develop training programs for gastroenterologists and radiologists, helping them to better recognize recurrences.
