Type 1. The most common type of stomach (gastric) neuroendocrine tumours is type 1. Between 70 and 80 out of 100 stomach NETs (between 70 – 80%) are type 1. They are slightly more common in women than in men. They are often associated with a condition called chronic atrophic gastritis.

How are neuroendocrine tumors graded?

The WHO grades for NETs include: Grade 1 (low-grade tumor): These cells divide at a low rate and therefore grow slowly. Grade 2 (intermediate-grade tumor): These cells divide at an intermediate rate. Grade 3 (high-grade tumor): These cells divide at a fast rate and therefore grow quickly.
