We study retrospectively 123 cases of patients suffering from Ta/T1/T2 vesical tumour so as to evaluate the Disease Free Period as a predictive factor of relapse potential, capability of progression and survival.
This parameter has no influence over the variables that define the progression of the tumour, but it has a close correlation with relapse potential; Annual Relapse Rate (p less than 0.001) and Mean Interval between Relapses (p less than 0.0001). We were not able to show any relationship between Disease-Free Period and Survival, however it defines those tumours which relapse due to tumoural persistence.
These tumours progress in stage in 80% of cases and 75% of these do so with deep tumours.
