0 (absence of immunoreactivity), 0% of positive epithelial and/or stromal cells; 1 (weak immunoreactivity), 1–35% of positive epithelial and/or stromal cells; 2 (moderate immunoreactivity), 36–70% of positive epithelial and/or stromal cells; 3 (intense immunoreactivity), >70% of positive epithelial and/or stromal cells.
