Abstract:
The efficacy of two protocols for the prevention of relapse using Mitomycin-C and alpha-Interferon in 56 patients with surface bladder carcinoma (stages Ta-T1) treated with TUR was compared in a prospective study. Relapse percentages and rates, related to the tumours' presentation characteristics (single, multiple, primary, recurrent), as well as their systemic and local toxicity, were evaluated. The study of statistical significance is made using the squared-chi test, and it is completed with a Fisher's test for groups containing few elements for accuracy. The results show no statistical differences (log rank p = 0.313) between the two groups of endovesical therapy, both confirming to be effective as adjuvant therapy to TUR in surface bladder tumours.
