T1 CRC protocol 

With the start of the screening on colorectal cancer (CRC) in the Netherlands, it was expected that within a few years 8-40% of all detected colorectal cancers would be early cancers (T1 tumours). This development did necessitate a better understanding of the prognosis, patient selection, treatment options and follow up of this specific group of patients.

The T1 CRC working group developed an evidence-based guideline.

You can access the guideline via the ‘richtlijndatabase‘.


On the 13th of February, 2024, we organised a webinar about the main changes in the care fore patients with a T1 tumor. You will be well informed again based on 4 cases with questions/answers.

You will soon be able to watch this webinar again via this website/page.
