DE NOVO MUSCLE INVASIVE BLADDER CANCER: IS THERE A CHANGE IN TREND?

Abstract

Analysis of our data supports the findings of the earlier series that the majority of patients present with muscle invasive bladder cancer. However, there is a significant decrease in the percentage of tumors invading the muscularis propria at presentation. Although this observation is encouraging, we emphasize that it is not as dramatic as the stage migration associated with prostate cancer, which may be largely attributed to the widespread use of prostate specific antigen for early detection. Therefore, we support the suggestion that therapeutic gains might follow from improved education regarding the signs and symptoms associated with bladder cancer, with enhanced focus on women and consideration of screening methods for those at high risk for bladder cancer.
