This study analyzed gastrinoma cases, revealing frequent multiple lesions and hormone secretion alongside typical symptoms. These findings aid in improving gastrinoma diagnosis and treatment strategies.

Area of Science:

Endocrinology
Gastroenterology
Oncology

Background:

Gastrinoma, a neuroendocrine tumor, often presents with complex symptoms.
Accurate diagnosis and effective treatment remain challenging.

Purpose of the Study:

To enhance the clinical diagnosis and treatment of gastrinoma.
To identify characteristic features of gastrinoma in a clinical series.

Main Methods:

Retrospective analysis of twelve gastrinoma cases over 30 years.
Detailed review of clinical presentation, pathology, and treatment outcomes.

Main Results:

High incidence of severe diarrhea (7/12) and shock.
Association with Multiple Endocrine Neoplasia type I (3/12).

Duodenal gastrinoma (3/12) and multifocal lesions (9/12) involving multiple organs.

Common multifocal lesions and multiple hormone secretion (5/6 patients).

Tumor sensitivity to chemotherapy observed in some cases.

Conclusions:

Gastrinoma frequently presents with multifocal lesions and multiple hormone secretion.
These features, in addition to hypergastrinemia symptoms, are crucial for diagnosis.
Findings support refined diagnostic and therapeutic approaches for gastrinoma.
