Overview
Barium studies may be diagnostic of stomach cancer. The sensitivity of barium meals may be 14%. False-negative barium studies can occur in 50 percent of cases. There are three types of early gastric cancer which include polypoid, ulcerated, and superficial.
Barium studies
- Barium studies (double contrast barium) can identify both malignant gastric ulcers and infiltrating lesions.
- False-negative barium studies can occur in 50 percent of cases.[1]
- For early gastric cancer, the sensitivity of barium meals may be 14%.[2]
- Early gastric cancer has three types:
- 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 may further be of the following types:[3]
- Polypoid cancer can be lobulated or fungating.
- Lesion on anterior wall: A thin layer of barium trapped between edge of mass & adjacent mucosa.
- Ulcerated carcinoma: 70% of all gastric cancers.
