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. 

On the 10th of June 2025 we organised a case based webinar about the main changes in the guidelines section 5.1 / 5.2: the treatment of T1 and T2 tumours.
