Abstract 642P
Background
Biomarker from blood could be a useful and non-invasive tool to provide real-time information in the procedure of treatment.
Methods
To further understand the role of plasma mRNA in chemo-efficiency prediction, several mRNA levels were assessed in plasma and paired FFPE tumor tissues, and were correlated with chemosensitivity.
Results
In the 133 patients with locally advanced gastric cancer (Stage III), significant correlations were observed between plasma and tumor mRNA levels of BRCA1(rho = 0.532, P
Conclusions
Plasma mRNA expression levels mirror those in the tumor and can be used as promising predictive biomarkers to predict chemo-efficiency.
