Semiquantitative analysis of IRS-1 expression in prostate biopsies

The staining intensity was scored as for IGF1R expression using a 4-point scale: 1+, none or minimal; 2+, light; 3+, moderate; 4+, heavy. The Table records staining for 16 benign (B) and 16 malignant (M) biopsies, including 11 benign and 11 malignant retrospectively collected fine-needle biopsies used for IGF1R analysis, and 5 benign, 5 malignant prospectively-collected samples.
