We also found the expression in histological differentiation was significant (p = 0.028) and the expression difference between the high grade and low grade DCIS was also significant (p = 0.035), Spearman correlation of MTDH expression levels to them were 0.379 (p = 0.021) and 0.452(p = 0.012), respectively. Here, MTDH is linked to ductal breast carcinoma in situ.
