Factors Influencing the Recurrence Rate of Bladder Cancer

Abstract

A prospective analysis was done on 318 patients with bladder cancer observed during a 4-year period. We examined the predictive value for tumor recurrence of the initial grade, stage, number and size of bladder tumors. None of the observed parameters alone or in combination could predict tumor recurrence. Cystoscopy and cytology, as well as random bladder and tumor biopsies, were part of the diagnostic studies.
