Background: Pancreatic neuroendocrine neoplasms are a heterogenous group of rare tumors whose natural history remains poorly defined. Accurate prognostication of pancreatic neuroendocrine neoplasms is essential for guiding clinical decisions. This paper aims to summarize all the commonly utilized and recently proposed prognostication systems for pancreatic neuroendocrine neoplasms published in the literature to date.
Methods: A systematic review of Pubmed, Scopus, and Embase databases, of the period from January 1, 2000-November 29, 2016, was conducted to identify all published articles reporting on prognostication systems of pancreatic neuroendocrine neoplasms.
Results: A total of 23 articles were included in our review, and a total of 25 classification systems were identified. There were 2 modifications of the World Health Organization 2004 criteria, 4 modifications of the World Health Organization 2010 criteria, 2 modifications of the American Joint Committee on Cancer 2010 staging system, 3 modifications of the European Neuroendocrine Tumor Society 2006 tumor, node, metastasis staging system, 7 novel categorial classification systems, and 2 novel proposed continuous classifications. The most commonly included variables included age, size of tumor, presence of distant and lymph node metastases, Ki-67 index, and mitotic count.
Conclusion: Numerous prognostication systems have been proposed for pancreatic neuroendocrine neoplasms, of which the most commonly used systems presently include the World Health Organization 2010 criteria and the two tumor, node, metastasis staging systems by the European Neuroendocrine Tumor Society and the American Joint Commission on Cancer. However, prognostication systems for pancreatic neuroendocrine neoplasms continue to evolve with time as more prognostication factors are identified. More validation and comparative studies are needed to identify the most effective prognostication system.

Fibrolamellar hepatocellular carcinoma (FL-HCC) is a primary liver tumour presenting at a young age. Aggressive surgery of FL-HCC is the mainstay of management unlike other malignancies where metastatic stage precludes curative surgery. There are limited reports of response of FL-HCC to systemic therapies predominantly owing to its rarity.

Background: The APOE ε4 allele is the most prominent genetic predisposition for sporadic Alzheimer's disease (AD). Amylin, a neuroendocrine hormone co-secreted with insulin from the pancreas, is increased in blood in AD and readily forms neurotoxic homo- and hetero-oligomers with β-amyloid in AD. Previously, we showed that intravenously infused ApoE4 in rats expressing human amylin specifically in the pancreas led to increased brain amylin accumulation.

An asymptomatic 79-year old woman presented with a 40 mm pancreatic cystic lesion, located in the pancreatic body-tail and consistent with branch-duct intraductal papillary mucinous neoplasm (BD-IPMN) without "high risk stigmata". During a 4-year follow-up period, imaging showed no mural nodules or main pancreatic duct dilation, and serum CEA and CA19.9 were within normal range.

However, research on grading and assessing the Ki67 proliferation index in FNA samples is limited.
Methods: This study analyzed 335 EUS-FNA cases performed between 2016 and 2022, of which 12 cases of PanNET were further evaluated.
Introduction: Although neuroendocrine neoplasms (NENs) have a good prognosis, distant metastasis remains a crucial prognostic factor. Survivin, a tumor-associated antigen, is overexpressed in several solid tumors, indicating poor prognosis. We aimed to evaluate the clinical significance and role of survivin as a therapeutic target for NEN.
