Inverse correlation between GPX4 and 8-OHdG expression. a GPX4-positive and 8-OHdG-negative groups show the worst prognosis, though there were no significant differences in OS between the four subgroups. b GPX4-positive and 8-OHdG-negative groups show the worst prognosis, though there were no significant differences in PFS between the four subgroups. c GPX4-positive and 8-OHdG-negative groups show significantly poorer prognosis in OS than the other groups (P = 0. 0170). d GPX4-positive and 8-OHdG-negative groups show a significantly poorer prognosis in PFS than the other groups (P = 0.0005)
