Overview

Fluoroscopy may be diagnostic of stomach cancer.

Fluoroscopy

Early gastric cancer (elevated, superficial, shallow):

• Type I: elevated lesion, protrudes >5 mm into lumen (polypoid)
• Type II: superficial lesion (plaque-like, mucosal nodularity, ulceration)
• Type III: shallow, irregular ulcer crater with adjacent nodular mucosa and clubbing/fusion/amputation of radiation folds

Advanced gastric cancer:

• Polypoid cancer can be lobulated or fungating
• Lesion on dependent or posterior wall; filling defect in barium pool
• Lesion on nondependent or anterior wall; etched in white by a thin layer of barium trapped between edge of mass & adjacent mucosa
• Ulcerated carcinoma (penetrating cancer): 70% of all gastric cancers
