Purpose : Transforming growth factor-¥â(TGF-¥â) is a potent modulator of cell
proliferation, differentiation, angiogenesis and immune system. We evaluate the
significance of the expression of TGF-¥â1 and TGF-¥â2 and correlation with Ki-67 as
prognostic factors in prostate cancer.
Materials and Methods : In order to investigate the expression of TGF-¥â1, TGF-¥â2
and Ki-67, we analyzed immunohistochemical staining from paraffin blocks of 22 cases
of the prostate carcinoma and adjacent normal prostate.
Results : The TGF-¥â1 straining scores of the tumor cells were higher than those of
the adjacent normal epithelial cells(p=0.001). The TGF-¥â2 staining scores of the tumor
cells were also higher than those of the adjacent normal epithelial cells(p=0.003).
However no correlation was observed 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 was not correlated
with the staining score of TGF-¥â1 and TGF-¥â2. Ki-67 labelling index(LI) was
significantly associated with the histologic grade, while no relationship was observed
between Ki-67 LI and clinical stage. TGF-¥âl and TGF-¥â2 staining score was not
statistically correlated with the Ki-67 LI.
Conclusions : These results indicate that the prostatic cancer was associated with
alteration of TGF-¥âl and TGF-¥â2 expression by prostatic epithelial cells which may
be biologically important in the development of prostate cancer and TGF-¥â1 and TGF-
¥â2 expression may be new target of treatment of prostate cancer Prognostic value of
TGF-¥â1 and TGF-¥â2 expression was not statistically significant but Ki-67 LI was
significantly associated with Gleason score.
