Analysis of immunohistochemical staining of RAGE and HMGB1 for TETs.

The percentage of epithelial tumor cells displaying staining for cytoplasmic or nuclear RAGE or HMGB1 is indicated. Cytoplasmic or nuclear staining intensity was scored as follows: score 0-3; 0, no staining; 1, weak; 2, moderate; 3, strong.TETs thymic epithelial tumors, RAGE receptor for advanced glycation endproducts, HMGB1 high mobility group box1, WHO World Health Organization, Intens.
