Immunohistochemical staining for IGF1R, IRS-1, and PTEN in paired biopsies of primary and metastatic prostate cancer

Table shows staining intensity (IGF1R and IRS-1) and extent (PTEN) in paired primary (P) and metastatic (M) human prostate cancer tissue. For IGF1R and IRS-1, staining intensity was scored as for Fig. 3 <$REFLINK> and Table 1 <$REFLINK> . The extent of PTEN staining was scored as 0 (no staining), 1+ (mixed, some tumor cells positive, some negative) or 2+ (all tumor cells positive), as described previously (28) .
