[Diagnosis of gastric carcinoma with a group of biochemical tests].
Results of five non-specific reactions (ceruloplasmin assay, Ehrlich's reagent colorimetry, heat-resisting reaction of serum and determination of indole and neutral sulphide in urea) for the diagnosis of gastric carcinoma were calculated by the use of multiple-factor analysis. The positive rates in 284 cases of gastric carcinoma (including 8 early lesions), 306 healthy donors and 1018 cases of benign gastric diseases were 78.2% (62.5% for the early gastric cancers), 0.7% and 15.7%, respectively. The results showed that these tests are valuable for the screening in a high incidence area of gastric cancer or as a supplementary diagnostic means of gastric carcinoma in clinical practice.
