Figure 2. Higher levels of oxidative damage correlate with enhanced survival rates of mCRC patients following bevacizumab treatment.

(A). Representative image of resected colorectal tumour tissue showing strong epithelial and weak stromal staining for the oxidative damage marker, 8-oxo-dG (B-C). Kaplan-Meier survival curves of above (dotted line) and below (continuous line) median levels of epithelial staining intensity versus overall survival in months, where (B.) nuclear and (C.) cytoplasmic staining with p values=0.042 and 0.038 respectively, n=75.
