2.Chinese expert consensus on gastroenteropancreatic neuroendocrine neoplasms (2022 edition).
Chinese Journal of Oncology 2022;44(12):1305-1329
Gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) are highly heterogeneous tumors. According to the 2019 World Health Organization classification and grading criteria for neuroendocrine neoplasms of the gastrointestinal tract and hepatopancreatobiliary organs, GEP-NENs include well-differentiated neuroendocrine tumors (NETs), poorly differentiated neuroendocrine carcinomas (NECs), and mixed neuroendocrine-non-neuroendocrine neoplasms (MiNENs). GEP-NETs may present as hormonally functioning or nonfunctioning tumors and may have distinct clinical features based on their sites of origin. The Expert Committee of Neuroendocrine Tumors, Chinese Society of Clinical Oncology revised and updated the 2016 version of Chinese expert consensus on GEP-NENs. The update the consensus includes the epidemiology, clinical manifestations, biochemical and imaging examinations, pathological features, and treatment and follow-up of GEP-NENs.

The technology of electronic chromoendoscopy consists of narrow band imaging (NBI) and fuji intelligent chromo endoscopy (FICE). The two skills help distinguish between normal mucous membrane and focal zone and raise the detecting rate between the abnormal proliferation and early cancer. Therefore, the exploring research for type selection index of the two technologies and systems will be beneficial to the choice of the highest cost-effective endoscopy system and to the avoidance of wasting resources. By comparing all the indexes, and with purpose of clinical usage, NBI system has advantage over the FICE system. But with purpose for scientific research, the FICE system will be the better choice.

Gastrointestinal stromal tumors (GISTs) are rarely noted in association with neurofibromatosis-1 (NF-1, von Recklinghausen disease) as an individual gastrointestinal manifestation. We report here a case of multiple GISTs with an abundant skeinoid fiber in the jejunum of a 43-year-old woman diagnosed as NF-1. Histologically, the tumors were composed of uniform spindle-shaped cells with a fascicular pattern, almost indistinguishable from the histology characteristic of usual GISTs. However, multiple synchronous tumor occurrence, abundant skeinoid fiber, and presence of microscopic miniatures of stromal tumors are additional characteristic features of this case.

Patients with neurofibromatosis-1 (NF-1) have increased susceptibility to a variety of malignancies. Here, we document a rare case of two separated ileal adenocarcinomas in NF-1. The adenocarcinomas were surrounded by a diffuse tubular adenomatous lesion of the mucosa, and ganglion cells were scattered in the NF background. We found this case meaningful for several reasons: two separated adenocarcinomas arising in an unusual ileal segment, the association with precancerous tubular adenoma, and the presence of ganglion cells, which suggests ganglioneuromatosis in NF-1.
