ERBB2 and neoplasm: Upon examining the mRNA expressions of VEGFA, ERBB2 and MET in cancerous vs non-cancer normal tissue (n=22), we first confirmed that between the two arms, expressions of these three markers in patients' tumor (normalized to paired normal tissue) didn't have any significant difference as the baseline, i.e., the p values for VEGFA, ERBB2 and MET mRNA expressions between the two arms are 0.81, 0.46 and 0.56, respectively (n=13 in arm A, n=9 in arm B).
