Figure 1b: P53 distribution in patients with DCI and T1a. P53 negativity, 1+ expression, and 2+ expression (overexpression) were observed in 166 cases (62%), 62 cases (23%), and 35 cases (13%) of patients with DCIS and in 48 cases (56%), 17 cases (20%), and 21 cases (24%) of patients with T1a, respectively. The P53 overexpression rate was significantly higher in patients with T1a (p=0.001).
