RECURRENCE AND PROGRESSION IN LOW GRADE PAPILLARY UROTHELIAL TUMORS

Abstract

More than 90% of patients with stage Ta, WHO grade I have a benign form of bladder neoplasm, and few have truly malignant tumors. Future research should focus on reducing the number of recurrences and followup cystoscopies, and finding methods to identify malignant tumors so that pertinent treatment can be instituted. Subgrouping of WHO grade I bladder tumors as papillary neoplasm of low malignant potential and low grade papillary carcinoma seems to add valuable prognostic information.
