Chromosome 7 polysomy in different groups of clear cell renal cell carcinoma (CCRCC) regarding EGFR immunohistochemical staining intensity: (a) the number of tumors categorised as polysomic decreases with attenuation of staining intensity (p = 0.019, Pearson's χ2-test). Black bars represent percentage of tumors with chromosome 7 polysomy, white bars represent percentage of tumors without chromosome 7 polysomy; (b) the number of tumor cells showing chromosome 7 polysomy is declining with attenuation of EGFR immunohistochemical staining (p = 0.004, one-way ANOVA).
