A weak or absent expression of CD57 was found in 4 cases (8%) from the TMA “incidental PCa,” in 93 cases (11%) from the TMA “prostatectomy 1,” in 281 cases (14%) from the TMA “prostatectomy 2,” in 27 cases (9%) from the TMA “prostatectomy 3,” and in 22 cases (29%) from the TMA “lymph nodes.” Details of the proportions of staining patterns in the five TMAs are given in Figure 2. Here, B3GAT1 is linked to posterior cortical atrophy.
