2. FIG. 1
Whole-mount sections of prostates. (A) Close-up view of a single prostate whole-mount section. The tumor is present within the black line. Within the tumor, the areas with cytopathic effect are stained green (yellow arrows), while those with no effect remain pink. Each image represents a different patient. (B) Large prostatic carcinoma showing large areas showing cytopathic effect. (C) Small prostatic carcinoma with very little cytopathic effect. (D) Large bilateral tumor showing cytopathic effect on both sides of the prostate.

4. FIG. 3
Local immune response results. (A) CD8+ cells are increased significantly in the tumors of patients treated with HSV-tk (GT) compared to controls (C). (B) CD20+ cells. (C) CD68+ cells (macrophages) are increased in the nonneoplastic tissues. In each graph, the first two bars on the left represent benign nonneoplastic prostate (B) and the two on the right the tumor (T).

5. FIG. 4
Bimodal increase in IL-12 is seen at 1 week and at the time of radical prostatectomy. TGF-β1 values trend in the opposite direction.

6. FIG. 5
Detection by FACS of total CD8+ and DR+CD8+ T cells in peripheral blood after vector injection. Note the significant increase of both.

7. FIG. 6
NK cell levels decreased and reached a nadir at the end of the ganciclovir treatment, rose slightly on the day of surgery, and again at 2–6 months, but remained significantly lower than injection day levels. B cell levels remained almost unchanged, except for at 2–6 months.

8. FIG. 7
CAR expression is membranous and is present in (C) HGPIN and (A, B) cancer at differing levels. (D) The membranous staining (yellow arrow) is broken into granules in areas of cytopathic effect (red arrowhead). (E, F) Whole-mount sections of prostates showing the tumors delineated in black and the areas of cytopathic effect shaded in green (red arrowhead). The left image shows areas with high expression of CAR in red and lower expression in blue. No expression has no shading. Note that the areas with cytopathic effect seem to have greater expression of CAR.
