SRI and posterior cortical atrophy: In the comparison of sorcin levels and sorcin staining percentages of PCa patients with histopathological and clinical findings; while serum sorcin level was found to be higher in patients with positive lymph node, patients with cribriform pattern and patients with BCR, no significant difference was found in terms of sorcin staining percentages in any histopathological finding (P = .018 for lymph node positivity, P = .02 for cribriform pattern, P = .049 for BCR) (Table 2).
