Overview
Fluroscopy
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 4
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[1]
