Overview
Biopsy may be helpful in the diagnosis of stomach cancer. It has a sensitivity of 98% to diagnose gastric cancer but may be negative in linitis plastica. It is commonly used nowadays as first line of treatment for superficial lesions.
Endoscopy and Biopsy
- The diagnosis of early lesions appears to be increasing since upper gastrointestinal endoscopy became widely used.
- Obtaining seven biopsies from the ulcer margin and base have a sensitivity of 98% to diagnose gastric cancer.[1]
- It may be falsely negative in linitis plastica cancers.[2]
- Nowadays, guidelines consider endoscopic resection as a first-line treatment for gastric superficial lesions.[3]
