Abstract
OBJECTIVE
The aim of this study was to evaluate cathepsin D as a prognostic marker in invasive bladder cancer and to determine its relationship with stage, grade, lymph-node metastasis and survival too.
MATERIAL AND METHODS
An immunohistochemical staining of 32 radical cystectomy specimens suffering from transitional cell carcinoma was performed, using a monoclonal antibody anti-cathepsin D (Novocastra). We made a semicuantitative measurement of the cathepsin D expression in the tumor and in the peritumoral stroma in a 400 x microscopic high power field. Patient population was composed of 31 men and 1 woman with a mean age of 63.25 years. The mean follow up was 23.6 months. Stage was classified with the WHO 1997 classification. Grade was classified with the ISUP/WHO 1998 classification. For the statistical analysis the Chi-square test, Pearson's test R, the Kaplan Meier method and the log-rank test were used.
RESULTS
The pathological stages of the surgical specimens were as follows: pTo:3.1% (1), pT1:12.5% (4), pT2:15.6% (5), pT3:34.4% (11). (p < 0.001) A high cytologic grade was found in 81.25% of the tumors. There was a 43.8% progression rate and 40.6% mortality. There was no statistically significant relationship among Cathepsin's D levels in the stroma and lymph node metastases, stage, or grade (p = 0.473, p = 0.604, p = 0.2423). There was no statistically significant relationship among Cathepsin's D levels in the tumor and lymph node metastases, stage or grade (p = 0.496, p = 0.722 and p = 0.461). The cathepsin D levels, neither in the stroma nor in the tumor, showed no influence neither on the disease free intervals nor in the survival rates (p = 0.785; p = 0.355 and p = 0.614; p = 0.601 respectively).
CONCLUSIONS
Immunohistochemical Cathepsin D levels do not seem to play a role in the prognostic of transitional tumors of the urinary bladder.
