In gastric cancer the tumor markers CEA, TPA and CA 19-9 display relatively low sensitivity, which in relation to a specificity of 90% lies between 20% and 25%. Compared with the simple ESR method, these sensitivities are not remarkably greater. But a combination of parameters based on discriminant analysis achieves distinctly greater sensitivities.
