Overview
Fluoroscopy may be diagnostic of stomach cancer.
Barium studies
Barium studies can identify both malignant gastric ulcers and infiltrating lesions
false-negative barium studies can occur in as many as 50 percent of cases [17].
early gastric cancer where the sensitivity of barium meals may be as low as 14 percent [18].
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[1]
