| Outline of Final Research Achievements |
Currently, there is a desperate need for developing more sensitive, real time detecting method to diagnose gastric cancer in early stage. Because most of the patients diagnosed with gastric cancer are unsuitable for curative surgery since many patients already have distant metastasis at diagnosis, which resulted in extremely poor prognoses. Until now, we reported ST6GalNAc-I that is known as the sialyl-Tn antigen synthase is highly expressed in gastric cancer and related with its malignant potential. We then examined expression of ST6GalNAc-I mRNA in peripheral blood by using digital PCR, so-called "liquid biopsy", and then we verified that the relationship between its copy number expression and their clinical courses. We are now developing a new monitoring biomarker system using this technique for gastric cancer treatment.
