Helicobacter pylori infection has been identified as a risk factor for certain types of gastric cancer.
However, the extent to which H pylori eradication decreases the risk of gastric cancer is unknown, raising the question of whether population-based H pylori screening should be undertaken.
To compare clinical and economic effects of H pylori screening, with and without confirmatory testing. with no screening to prevent gastric cancer.
Decision analysis incorporating a Markov simulation.
Simulated cohorts of men and women with varying risk of gastric cancer.
Three strategies were evaluated :
(1) no screening ;
(2) H pylori serologic testing, treat those positive for H pylori, no follow-up testing ;
and (3) H pylori serologic testing, treat those positive for H pylori, followed by a test to confirm H pylori eradication, retreat those who test positive.
In the principal analysis, the risk of gastric cancer after H pylori eradication was assumed to be similar to that for those without H pylor infection.
Scenarios with less optimistic assumptions regarding risk reduction of cancer were evaluated.
Gastric cancer rates, discounted cost per life-year saved. (...)
