Figure 9. Relationship between therapeutic response and serum miR-148a expression in mCRC patients. We collected the serum samples of 24 mCRC patients before they received treatment with bevacizumab plus FOLFIRI as first-line regimen. (A) After treatment, 14 patients showed partial response (PR) and 10 patients had progressive disease (PD). (B) miR-148a expression was significantly higher in the serum samples of the 14 PR patients than in those of the 10 PD patients (P = 0.026).
