Purpose : Transforming growth factor-¥â (TGF-¥â) is a multipotent growth factor
affecting development, homeostasis, and tissue repair We evaluate the significance of the
expression of TGF-¥â1 and TGF-¥â2 and correlation with prognostic factors in prostate
cancer.
Materials and Methods : In order to investigate the expression of TGF-¥â1 and TGF-¥â
2, we analyzed Immunohistochemical staining from paraffin blocks of 22 cases of the
prostate carcinoma and adjacent normal prostate.
Results : The expressions of TGF-¥â1 and TGF-¥â2 were noted in the cytoplasm of
tumor cells, nounal epithelial cells and stroma. The staining intensity and areas were
examined and scored from 0 to 5. The TGF-¥â1 staining scores of the tumor cells were
higher than that of the adjacent normal epithelial cells (p=0.001). The TGF-¥â2 staining
scores of the tumor cells were also higher than that of the adjacent normal epithelial
cells (p=0.003). However, there were no correlation between tumor surrounding stroma
and normal stroma in TGF-¥â1 and TGF-¥â2 staining scores. The serum PSA level, the
clinical stage, the Gleason score and the lymph node metastasis of the tumor did not
correlated with the staining score of TGF-¥â1 and TGF-¥â2.
Conclusion : These results indicate that the prostatic cancer was associated with
alteration of TGF-¥â1 and TGF-¥â2 expression by prostatic epithelial cells which play a
role in prostatic calcine genesis .
