Purpose : Volumetric change of prostate is the result of unbalanced proliferation and
apoptosis. We investigated the characteristics of proliferation and apoptosis in
hypertrophic prostate.
Materials and Methods : Proliferative and apoptotic rates were quantitated with
immunoprofiles of proliferative cell nuclear antigen(PCNA) and apoptotic body with 46
paraffin-embeded BPH specimen. When the rate of proliferation was higher than that of
apoptosis, we defined as proliferation active group.
Results: Proliferation and apoptotic rates of stromal and epithelial cells were 4.5%,
2.9% and 1.9%, 1.1%, respectively(p<0.05). There was modest correlation between
stromal volume and the proliferation rate of stromal cells(p<0.05, R=0.3209). There was
no volumetric difference in the prostate between proliferation active and inactive
group(p>0.05).
Conclusions: These results demonstrate that stromal proliferation is the main cause of
prostatic hypertrophy. The unbalance between proliferation and apoptosis of prostatic
cells seems to be unsteady in time.(Korean J Urol 1998; 39: 454¡8)
