MKI67 and neoplasm: With respect to clinicopathological characteristics, we observed a statistically significant positive correlation between 5-mC and the Ki-67 marker (rS = 0.340, p = 0.049; Figure 2c) and between 5-hmC and the Ki-67 marker (rS = 0.341, p = 0.048; Figure 2f) in the tumor samples obtained during surgery (patients without NACT).
