title: The value of the lysosomal protease cathepsin-d in egyptian bladder-cancer.
abstract: Cathepsin D was measured in cytosols of 60 malignant bladder specimens and normal tissue from the same bladder at safety margin 5 cm of the tumor. Significant elevation in cathepsin D level (50 +/- 3.5 pmol/mg protein) in bladder carcinoma compared to normal tissue (12.7 +/- 1.58 pmol/mg protein) was found. At 100% specificity, cathepsin D sensitivity was 78%. The positivity rate of cathepsin D increased in the presence of lymph node metastasis. The higher concentration of cathepsin D in malignant bladder tissue vs. normal tissue and its correlation with lymph node metastasis could reflect its importance as a marker of metastatic potentiality of primary bladder cancer.
