Summary
This summary is machine-generated.Gastric neuroendocrine carcinomas/mixed neuroendocrine-non-neuroendocrine neoplasms (g-NEC/MiNEN) have a worse prognosis than other gastric cancers, but benefit from adjuvant therapy. This finding is crucial for understanding g-NENs and improving patient outcomes.
Area Of Science
- Gastroenterology
- Oncology
- Pathology
Background
- Gastric neuroendocrine neoplasms (g-NENs) represent a diverse group of tumors with varying clinical behaviors.
- Understanding the specific clinicopathological features and prognostic factors of different g-NEN subtypes is essential for effective patient management.
Purpose Of The Study
- To investigate the clinicopathological characteristics of gastric neuroendocrine neoplasms (g-NENs).
- To evaluate the prognostic implications of g-NENs, particularly comparing gastric neuroendocrine carcinomas/mixed neuroendocrine-non-neuroendocrine neoplasms (g-NEC/MiNEN) with other gastric malignancies.
Main Methods
- A retrospective analysis of 142 patients with g-NENs diagnosed between 2007 and 2021.
- Comparison of clinicopathological features and survival rates between g-NEN subtypes and other gastric cancers like gastric adenocarcinoma (GAC) and signet ring cell carcinoma (SRCC).
Main Results
- Gastric neuroendocrine carcinomas/mixed neuroendocrine-non-neuroendocrine neoplasms (g-NEC/MiNEN) demonstrated significantly worse prognoses compared to gastric neuroendocrine tumors (g-NET) (p < 0.001) and gastric adenocarcinoma (GAC) (p < 0.001).
- Within poorly differentiated GAC, g-NEC/MiNEN also showed a worse prognosis (p = 0.007).
- Patients with g-NEC/MiNEN who received postoperative adjuvant therapy exhibited significantly prolonged overall survival (OS) (p = 0.010).
Conclusions
- The prognosis of g-NEC/MiNEN is poorer than that of g-NET, GAC, and poorly differentiated GAC.
- Postoperative adjuvant therapy offers a survival benefit for patients with g-NEC/MiNEN.

Gastritis, defined by the inflammation or irritation of the stomach lining or gastric mucosa, manifests in several distinct forms: acute, chronic, reactive, and a specific subtype known as autoimmune metaplastic atrophic gastritis.
Acute gastritis presents as a sudden inflammation triggered by various stressors to the stomach lining, such as exposure to corrosive agents, local irritants like aspirin and other NSAIDs, alcohol consumption, radiation therapy, physical trauma, severe burns, sepsis,...
Gastric motility is the coordinated contraction and relaxation of stomach muscles that convert ingested food into chyme, a semi-liquid substance ready for further digestion in the intestines. The process begins with the vagus nerve inducing the relaxation of the smooth muscles in the fundus and body of the stomach, allowing these regions to expand and accommodate up to approximately 1.5 liters of food and liquid.
Peristaltic Waves and Chyme Formation
Upon food entry, the stomach initiates...
