Abstract

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.
