NeoplasmNeuroendocrineRectumNeuroendocrine neoplasms of the rectum (R-NENs) are rare; however, their incidence has increased almost threefold in the last few decades. Imaging of R-NENs includes two primary categories: anatomic/morphologic imaging comprised of endoscopic ultrasound (EUS), computed ...
neuroendocrine neoplasm (pancreas) A general term for tumours (e.g., glucagonomas, insulinomas, etc.), which arise in the endocrine cells of the pancreas. Prognostic indicators Depends on TMN stage when diagnosed; mitotic rate and MIB-1/K1-67 labelling index, which determine tumour grade; inva...

The origin of neuroendocrine cells can be traced back to gastrointestinal stem cells rather than neurocrest cells. In recent years, extensive efforts have been made to elucidate the biology of NETs. The protein synthesis, hormone secretion, and proliferation of these tumors primarily rely on interact...
The major pathological types were neuroendocrine neoplasm G1 in 31 patients, and neuroendocrine neoplasm G2 in 7 patients. Tumor-node-metastasis (TNM) stages I, II, III and IV tumors accounted for 76.3% (29/38), 5.3% (2/38), 7.9% (3/38) and 10.5% (4/38) of patients, respectively...
The decision between radical and palliative surgical approaches is influenced by the location of the primary tumor [106]. Fig. 1 The diagnosis and management of GI-NENs. In different locations of the gastrointestinal tract, including the stomach, colon, and rectum, among others, tumors have been...
Case presentation We report the case of a 40-year-old woman that was diagnosed with a neuroendocrine neoplasm (NEN) of the rectum and multiple synchronous liver metastases ten years ago. She initially responded well to transarterial chemoembolization (TACE), resulting in prolonged disease ...

Although they have retained their well-differentiated neuroendocrine growth pattern, their Ki67-index greater than 20% gives them a grade G3 that shifts them into the poorly differentiated neuroendocrine neoplasm category.24 Neoplasms of this type most often originate in the pancreas and increase their...
The term ‘carcinoid’, originally introduced by Oberndorfer in 1907, should indicate the more benign behaviour of this type of neoplasm compared to adenocarcinoma. In terms of metastatic potential, NETs of the gastrointestinal tract are generally suspected of being malignant. However, there is evidenc...
