  • NOTE: Slides were scored on the percentage and intensity of tumor cell staining using a 0 to 3+ scale: 0, no detectable staining; 1+, ≤25% cells positive and low intensity; 2+, 25% to 75% cells positive and low to moderate intensity; and 3+, ≥75% cells positive with intense staining (see Fig. 2A).
