Аннотация
Twenty patients with bladder carcinoma (14 transitional cell carcinoma and six squamous cell carcinoma) and ten controls of (four with bilharzial lesions, three without and three with metaplasia and dysplasia) were subjected to immunocytochemical and immunohistochemical studies. Bladder and urine samples examination were carried out with the high molecular weight cytokeratin and broad spectrum keratin antibodies using peroxidase anti-peroxidase. Cytokeratins of high molecular weight were expressed in all squamous cancer while broad spectrum keratin was positive in 83.3%. The transitional cell carcinoma was positive in 50% with both cytokeratin and broad spectrum keratin. Urine shedded were positive in 83.3% and 66.7% of squamous cell carcinoma with high molecular weight cytokeratin and broad spectrum keratin respectively. However, each of them was positive in 50% of transitional carcinoma, and negative with non-malignant cases except with metaplasia and dysplasia.
