    Abstract:
    OBJECTIVES: To explain the overall survival (OS) and disease free survival (DFS) in relation to nm23-H1 protein, DNA-ploidy and S-phase fraction (SPF) in transitional cell carcinoma of the bladder. PATIENTS AND METHODS: Ninety-four samples were obtained from patients with transitional cell carcinoma of the bladder examined between 1994 and 1996. The patients were underwent cistectomy or surgical biopsy and the material was histologically evaluated according to World Health Organization classification. Nm23-H1 protein expression in immunohistological staining and DNA ploidy, S-phase fraction by flow cytometric were performed. RESULTS: The correlation between OS and staging, grading, DNA-ploidy and S-phase was significant; whereas the overall survival and nm23-H1 protein, was not significant. The relationship between DFS and stage, DNA-ploidy and S-phase had a significant value. The correlation between DFS and age, sex, grading and nm23-H1 protein was not significant. There was no significant difference in age, sex, stage, grading, DNA-ploidy and SPF distribution between patients with nm23-H1 positive bladder cancer and those with nm23-H1 negative tumours. CONCLUSION: In our study, multivariate analysis showed that stage, ploidy and SPF were the strongest prognostic factors in predicting disease-free survival and prolonged survival, while nm23-H1 expression was not related to disease progression and/or prolonged survival. This expression, therefore, does not appear to be an independent prognostic factor in bladder cancer, although a still larger number of patients and a longer follow-up period are now needed for a definitive assessment of the prognostic significance of nm23-H1 expression.
