Overview
Screening cancer
The two main modalities for gastric cancer screening are upper endoscopy and contrast radiography.
Upper endoscopy
- Upper endoscopy is more sensitive than other screening studies. It allows direct visualization of the gastric mucosa and obtaining biopsies.[1]
Contrast radiography
- Barium radiographs can identify malignant gastric ulcers, infiltrating lesions, and some early gastric cancers.[2]
- Barium studies can be false negative in 50 percent of cases. On the other hand, the sensitivity of a barium study may be 14 percent.[3]
- In patients with linitis plastica, barium study may be superior to upper endoscopy.
Effectiveness
- The sensitivity rates for upper endoscopy were 69 % and upper GI series were 37%.
- Both studies had a specificity of 96%.
- The upper endoscopy sensitivity in detecting a localized gastric cancer is higher than upper GI series.[4]
SCREENING STRATEGIES
Universal screening
- In countries with a high incidence of gastric cancer such as east asia countaries, universal screening is recommended.[5]
- In Japan, population-based screening for gastric cancer is recommended for individuals older than 50 years with conventional double-contrast barium radiograph with photofluorography every year or upper endoscopy every two to three years[6]
- Screening interval is recommended to be every two years but may be widened to a three-year rather than a two-year interval without significant effect.[7]
Selective screening of high-risk subgroups
- In areas of low gastric cancer incidence, screening for gastric cancer with upper endoscopy should be reserved for specific high-risk subgroups.[8]
- Individuals at increased risk for gastric cancer include those with the following:
- Gastric adenomas
- Pernicious anemia
- Gastric intestinal metaplasia
- Familial adenomatous polyposis
- Lynch syndrome
- Peutz-Jeghers syndrome
- Juvenile polyposis syndrome
