Purpose: The best predictors of prognosis in prostate cancer are the stage of disease
histologic differentiation. But, preoperative prediction of pathologic stage in prostate
cancer is currently limited and histologic differentiation may be somewhat subjective.
Therefore, more accurate predictors of biological progression are needed. The author
designed this study to determine the prediction efficacies of neovascularity and
proliferating cell nuclear antigen (PCNA) labeling index using immunohistochemical
staining.
Materials and Methods: Immunohistochemical stains in 48 cases of prostate cancers
and 5 loses of benign prostatic hyperplasia (BPH) were performed and analysed.
Microvessels were identified by immunostaining of endothelial cells for factor V¥²
-related antigen. PCNA labeling indices were obtained in 200x field by counting more
than 1,000 cells.
Results: 1 The mean microvessel count (MVC) was 34.2¡¾5.9 per 200X field 16 in
BPH group and 63.5 ¡¾38.6 (p<0.05) in prostate cancer group. The mean MVCs were
32.2, 38.3, 58.8, 78.1 and 86.8, from grade I to V respectively According to stage, the
mean MVCs were 40.8, 48.5,11.0 and 89.0 from A to D. Between well (grade ¥°-¥²) and
poorly (grade ¥³-¥´) differentiated cancer group, there was significant difference in MVC
(p<0.05). And also, the difference between localized and metastatic groups was
statistically significant. High MVC (MVC¡Ã60) group survived longer than low MVC
group, but the difference was not significant. 2. The mean PCNA labeling indices were
14.6¡¾ 8.0% in BPH group and 32.3 15.4% in cancer group. According to Gleason grade,
the mean PCNA labeling indices showed 33.4%, 30.8%, 26.3%, 38.0% and 36.6% from I
to V respectively. The mean values were 23.1%, 27.4%, 30.4% and 36.2% in stage A, B,
C and D. Between localized and metastatic groups, the difference of PCNA labeling
index was not statistically significant. The mean survival of high labeling index (B3o%)
group was 66.0¡¾ 12.2 months contrasted with 72.4¡¾14.6 months of low labeling index
group (p>0.05).
Conclusions: Microvessel density in prostate adenocarcinoma may be an another
prognostic factor supporting clinical stage and histologic differentiation. But negative
results were obtained for PCNA labeling index from this study, To further define MVC
as a predictor of prostate cancer, more enthusiastic and well designed studies are
needed.
