Endoscopy for Diagnosing Gastric Cancer: Accurate but Still Not Enough

Despite its good sensitivity, diagnosis using magnifying endoscopy with narrow-band imaging should still be confirmed with biopsy.

In areas of high incidence of gastric cancer, endoscopic screening is performed for early identification of lesions. Investigators in China prospectively evaluated the accuracy of magnifying endoscopy with narrow-band imaging (ME-NBI) in diagnosing 164 suspected gastric lesions in 146 consecutive patients. Two endoscopists used the ME-NBI findings of surface pattern and microvascular architecture to categorize lesions as noncancerous or cancerous (differentiated or undifferentiated carcinoma). All lesions were resected endoscopically or surgically, and endoscopic diagnoses were compared with histopathological results (gold standard).

The sensitivity and specificity of real-time ME-NBI for distinguishing cancerous from noncancerous lesions we…
