p53 nuclear immunoreactivity was determined in primary bladder tumours from 50 patients who developed metastatic bladder cancer. We investigated the relationship between p53 nuclear immunoreactivity and the response and outcome following chemotherapy. p53 nuclear accumulation was detected in 48% of the primary tumours using the PAb1801 antibody in archival paraffin-embedded tissue sections. All patients received platinum-based combination chemotherapy including methotrexate for metastatic disease. The response to chemotherapy did not relate to the prevalence of p53 nuclear overexpression: 50% of the patients expressing p53 nuclear reactivity achieved a response compared to 27% of those without p53 expression (P = 0.14); overall, 38% of the patients responded. The median survival after chemotherapy was 5.9 months; 8.4 months for patients with p53 nuclear reactivity compared to 5.2 months for those without (P = 0.38). Multivariate analysis showed that performance status but not p53 nuclear status was an independent prognostic factor for survival following chemotherapy. The results indicate that patients with p53 nuclear immunoreactivity in the primary bladder tumour do not have a lower response rate or poorer outcome following chemotherapy for metastatic disease than do patients without p53 nuclear reactivity.
