The invention discloses a gastric cancer serum detection marker, which is a polypeptide molecule with a sequence shown as SEQ ID NO. 1. The invention also discloses a detection method of the marker, a kit containing the marker and application of the marker. The polypeptide molecular fragment which shows high specificity expression in the serum of an early gastric cancer patient is obtained by screening, can be used as a serum detection marker for auxiliary diagnosis and detection of early gastric cancer, and thus, the possibility is provided for early discovery, diagnosis and treatment of gastric cancer. |
