Pancreatic neuroendocrine neoplasms (pNENs) are diverse tumors with increasing incidence. This review covers pNEN diagnosis, presentation, and treatment strategies for unresectable cases.
Area of Science:
- Oncology
- Gastroenterology
- Endocrinology
Background:
- Pancreatic neuroendocrine neoplasms (pNENs) encompass a spectrum of tumors, including pancreatic neuroendocrine tumors (pNETs) and neuroendocrine carcinomas (pNECs).
- There has been a notable rise in pNEN incidence over recent decades, accompanied by increased research interest.
- Despite advancements, classification and diagnostic criteria for pNENs remain subjects of ongoing discussion.
Purpose of the Study:
- To provide a comprehensive overview of pancreatic neuroendocrine neoplasms (pNENs).
- To detail the diagnostic work-up and clinical presentation of pNENs.
- To summarize current and emerging treatment options for pNENs, particularly for advanced or unresectable disease.
Main Methods:
- Literature review and synthesis of current research on pNENs.
- Analysis of diagnostic modalities and clinical staging for pNENs.
- Evaluation of therapeutic strategies, including surgical and non-surgical interventions.
Main Results:
- pNENs are a heterogeneous group requiring precise classification for optimal management.
- Early and accurate diagnosis is crucial for patient outcomes.
- Effective therapeutic strategies for advanced pNENs are still evolving, necessitating personalized treatment plans.
Conclusions:
- A clear understanding of pNEN classification and diagnosis is essential.
- Surgical resection is the primary treatment for resectable pNENs.
- Further research is needed to establish definitive treatment protocols for advanced and unresectable pNENs, addressing the current therapeutic uncertainties.

Pancreatic Juice and Secretion
When acidic chyme from the stomach enters the duodenum, it triggers the release of secretin, a hormone that prompts pancreatic juice secretion. After a fatty meal, cholecystokinin, another hormone, stimulates gallbladder contraction and enhances enzyme-rich...
Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
