Figure 2From: Stromal expression of miR-21 in T3-4a colorectal cancer is an independent predictor of early tumor relapseAssociation between miR-21 expression and recurrence-free survival in patients with T3-4a colorectal cancer. Kaplan-Meier survival curves for recurrence-free survival in all (A), stage II (B) and stage III (C) cancer patients according to miR-21 expression status. (A) High miR-21 expression is associated with recurrence-free survival in colon cancer patients but not in rectal cancer patients. (B) For the 138 patients with stage II cancer, the association between high miR-21 expression and recurrence-free survival is statistically significant only in colon cancer patients. (C) Among 277 stage III cancer patients, high miR-21 expression is not associated with poor recurrence-free survival.Back to article page
