Type I Gastric Neuroendocrine Tumors Diagnostics: 16 Years of Experience

#1512

Introduction: In our institution from 1998 to 2014 we have identified 72 patients with type I gastric neuroendocrine tumors (NET).

Aim(s): Majority of patients were woman – 85,7%. Most part (79,6%) of tumors were well-differentiated - G1 (Ki-67 lower than 2%) and only 14,3% were G2 (median Ki-67 – 4,3). In 3 (6,1%) patients G1 and G2 type I gastric NETs were found synchronously.

Materials and methods: More often tumors occurred in gastric corpus (93,88%), in 40,82% of them lesions diagnosed also in proximal parts of stomach and in 12,24% - in gastric antrum. Mean tumor size in G1 tumors was 0,58 cm (0,2 – 2,0 cm), whereas in G2 cases – 1,35 cm (0,5 – 3,0 cm), mean tumor amount in patients with G1 tumors was 11 (1 – 93), while in patients with G2 lesions – 2 (1-4).
