Summary
Current guidelines for endoscopy in dyspepsia are adequate for detecting gastric cancer, though most cases are advanced. This study supports existing criteria for early gastric cancer detection.
Area of Science:
- Gastroenterology
- Oncology
- Diagnostic Medicine
Background:
- Dyspepsia is a common symptom in both gastric cancer and benign conditions.
- Current guidelines recommend endoscopy for dyspepsia in patients with alarm symptoms or over 45 years old.
- These recommendations remain controversial.
Purpose of the Study:
- To evaluate the adequacy of current endoscopy referral criteria for detecting gastric cancer.
- To assess the effectiveness of alarm symptoms and age thresholds in identifying gastric cancer patients.
Main Methods:
- Retrospective analysis of 215 gastric adenocarcinoma patients.
- Classification of symptoms as alarm or non-alarm.
- Staging of cancers using the TNM system, defining potentially curable stages (T1-T3N(x)M0).
Main Results:
- Dyspepsia was present in 128 patients; 41 denied alarm symptoms and 15 were under 45.
- The current criteria excluded only 2.3% of patients from endoscopy.
- Tumor stage was not significantly associated with dyspepsia duration, age, or alarm symptoms.
Conclusions:
- The study supports current European Helicobacter pylori Study Group and American Gastroenterological Association guidelines for endoscopy in dyspepsia.
- Despite adequate criteria, most gastric cancers are detected at advanced stages.
