Glycans Bound to Serum Haptoglobin: a Novel Gastric Cancer Tumor Biomarker

Open, Parallel, Single-Site Study to Evaluate Sensitivity and Specificity of Newly Defined Diagnosed-biomarker for Gastric Cancer Pts and Cancer-free Healthy Volunteers

The purpose of this study is to evaluate sensitivity and specificity of newly defined tumor biomarker with gastric cancer pts and cancer-free healthy volunteers.

Measurements of specific glycosylation changes in serum haptoglobin.
