    Summary
    This summary is machine-generated.

    Gastric adenomas, potential precursors to cancer, were identified in 0.1% of upper GI tract exams. Some adenomas, particularly larger ones with irregular surfaces, showed early signs of gastric carcinoma.

    Area of Science:

    • Gastroenterology
    • Radiology
    • Oncology

    Background:

    • Gastric adenomas are neoplastic polyps of the stomach.
    • They carry a risk of malignant transformation.
    • Radiographic detection rates and characteristics are not well-established.

    Purpose of the Study:

    • To report the incidence and radiographic findings of gastric adenomas.
    • To compare findings with existing North American and European literature.
    • To identify adenoma features associated with early gastric carcinoma.

    Main Methods:

    • Retrospective review of approximately 11,000 upper gastrointestinal tract examinations.
    • Biphasic-contrast radiography as the primary imaging modality.
    • Correlation with endoscopic findings and histopathology.

    Main Results:

    • Fifteen gastric adenomas were identified in 11 patients (0.1% incidence).
    • Most adenomas (11/15) were ≤20 mm with smooth surfaces.
    • Four larger, irregularly surfaced adenomas (≥20 mm) in 3 patients were diagnosed as early gastric carcinoma (Type I and IIa).

    Conclusions:

    • Radiographic detection of gastric adenomas is uncommon but significant.
    • Larger adenomas with irregular surfaces may indicate early gastric cancer.
    • Findings differ from previous radiological reports, suggesting potential variations in detection or patient populations.
