Usefulness of gastric cancer screening using the serum pepsinogen test method.

Objective: The measurement of serum pepsinogen has recently gained attention as a candidate for a new screening test for gastric cancer. This method is particularly attractive given its lower cost and simplicity to administer relative to photofluorography. To compare the accuracy between the two screening methods, and to elucidate the usefulness of the serum pepsinogen test method, we performed this study.
