简介
Objectives
Optimal management of type 1 gastric neuroendocrine tumors (T1‐GNETs) remains unknown, with few reports on their long‐term prognosis. This study investigated the clinical characteristics and long‐term prognosis of T1‐GNETs.
Methods
We reviewed the medical records of patients diagnosed with T1‐GNET during 1991–2019 at 40 institutions in Japan.
Results
Among 172 patients, endoscopic resection (ER), endoscopic surveillance, and surgery were performed in 84, 61, and 27, respectively, including 27, 77, and 2 patients with pT1a‐M, pT1b‐SM, and pT2 tumors, respectively. The median tumor diameter was 5 (range 0.8–55) mm. Four (2.9%) patients had lymph node metastasis (LNM); none had liver metastasis. LNM rates were significantly higher in tumors with lymphovascular invasion (LVI) (15.8%; 3/19) than in those without (1.1%; 1/92) (P = 0.016). For tumors <10 mm, LVI and LNM rates …
