Summary
Squamous change occurs in 4% of gastric adenocarcinoma patients, increasing with cancer invasiveness. This metaplastic change is linked to adenocarcinoma growth, particularly in protruding types near the esophago-cardiac junction.
Area of Science:
- Gastroenterology
- Pathology
- Oncology
Context:
- Gastric adenocarcinoma is a significant global health concern.
- Understanding metaplastic changes in gastric cancer is crucial for diagnosis and prognosis.
Purpose:
- To investigate the incidence and characteristics of squamous change in gastric adenocarcinoma.
- To explore the relationship between squamous change and clinicopathological features of gastric cancer.
Summary:
- Squamous change was observed in 4% of 3,727 operated gastric adenocarcinoma patients.
- Incidence of squamous change increased with tumor invasiveness (0.47% early, 4.2% pm-invasive, 5.6% s-invasive).
- This phenomenon is considered a secondary metaplastic change associated with adenocarcinoma growth, prevalent in protruding types (63.5%) and well-differentiated adenocarcinoma with intestinal metaplasia (86.1%).
- Average patient age was 65.5, with a male to female ratio of 2.3:1.
- Cancer location was frequently in the upper third of the stomach (19.6%), near the esophago-cardiac junction.
Impact:
- Findings contribute to understanding the diverse histological patterns of gastric adenocarcinoma.
- Highlights the potential significance of metaplastic changes in gastric cancer progression.
- May inform future diagnostic and prognostic strategies for gastric adenocarcinoma.
