Representative staining intensity scores for ALHD1. A Macrophage staining at ×400. B (×400), case 4, pretreatment biopsy, score 0. C, D Case 5, pretreatment biopsy, scores 0 (stained cells are macrophages). E (×100) and F (×400), case 4, post treatment, score 1 for percent of tumor cells positive/score 2 for staining intensity of tumor cells (few to no macrophages are present). G (×200), case 16 pretreatment biopsy, score 0; H (×200), case 16 post treatment resection, score 1 for percent of tumor cells positive/2 for staining intensity. I (×400), case 20 pretreatment biopsy, score 1 for percent of tumor cells positive/1 for staining intensity; J (×400), case 20 post-treatment resection, score 1 for percent of tumor cells positive/3 for staining intensity. Higher magnification inserts are shown in the bottom right of A and B
