Fig. 6From: Immunohistochemical expression of 8-oxo-7,8-dihydro-2′-deoxyguanosine in cytoplasm of tumour and adjacent normal mucosa cells in patients with colorectal cancerKaplan–Meier curve, 15-year survival, Dukes A group, starting at 100 % survival. Green line represents patients with cytoplasmic reaction for 8-oxodG in tumour cells, blue line represents patients without reaction. Worse long-term survival of patients positive to 8-oxodG in early stage group is suspected due to systematic influence of oxidative stressBack to article page
