Scoring system applied for inflammatory cells immunoreactions: 0 (not detected); 1 (percentage of immunoreactive inflammatory cells per section 1–25%); 2 (percentage of immunoreactive inflammatory cells per section 26–50%); 3 (percentage of immunoreactive inflammatory cells per section >50%).
Scoring system applied for MHC classes I and II expression: 0: absent; 1: mild; 2: moderate; 3: intense.
