title: [Monoclonal antibodies (MIB 1, PC 10, 486p and p53) as prognostic factors for recurrent urothelial carcinoma of the urinary bladder].
abstract: Using an immunohistochemical method expression of PCNA, Ki-67, 486p and p53 antigen was investigated in paraffin sections of 119 patients with primary transitional cell carcinoma of the bladder. The purpose of this study was to detect recurring G1 and G2 bladder tumours compared with non-recurrent tumours. A relative large fraction of labelled cells for PCNA and Ki-67 was found in recurring G1 and G2 carcinomas. Moreover, recurrent transitional cell carcinomas showed a more positive staining pattern for 486p and p53, in contrast to non-recurrent carcinomas. Immunohistochemistry of these four antigens seems to yield additional information about the possibility of recurrence in G1 and G2 bladder carcinomas, thus allowing early, i.e. more aggressive, therapy.
