Purpose Of Review:
Gastric neuroendocrine neoplasms (g-NENs) are a rare type of stomach cancer. The three main subtypes have different pathogeneses, biological behaviours and clinical characteristics, so they require different management strategies. This article will provide an overview of g-NENs and highlight recent advances in the field.
Recent Findings:
Molecular profiling has revealed differences between indolent and aggressive g-NENs, as well as a new somatic mutation responsible for some familial type I g-NENs. Novel biomarkers have been developed which will hopefully improve diagnosis, treatment, risk stratification and follow-up. Patient treatment is also changing, as evidence supports the use of less aggressive options (e.g. endoscopic surveillance or resection) in some patients with more indolent tumours. g-NEN heterogeneity poses challenges in understanding and managing this rare disease. More basic science research is needed to investigate molecular pathogenesis, and future larger clinical studies will hopefully also further improve treatment and patient outcomes.
Insights

Area of Science:
- Gastroenterology
- Oncology
- Pathology
Background:
- Gastric neuroendocrine neoplasms (g-NENs) represent a rare group of stomach cancers.
- Distinct subtypes necessitate tailored management due to varied pathogenesis and clinical behavior.
Purpose of the Study:
- To provide a comprehensive overview of gastric neuroendocrine neoplasms.
- To highlight recent advancements in the understanding and management of g-NENs.
Main Methods:
- Review of recent molecular profiling studies.
- Analysis of novel biomarker development.
- Evaluation of evolving treatment strategies and clinical evidence.
Main Results:
- Molecular profiling identifies differences between indolent and aggressive g-NENs.
