ABSTRACT
OBJECTIVES:
Evaluation of a homogeneous series of Superficial Primary TCC of the Bladder. Utility of randomized biopsies (BMN). Study of risk factors and risk groups as a basis for determining treatment and followup patterns. MATERIALS ANDMETHODS:
Survey of 1,529 PSBT cases that underwent TURB and BMN, with a mean followup of 4.2 years. Strict statistical treatment multivariate analysis using Cox logistic regression according to Kaplan-Meier curves.RESULTS:
Tumor features of note single tumor (65%), smaller than 1.5 cm (45%), high grade (G3 26%), and high stage (T1 64%). BMN showed associated CIS in 284 cases (19%). Main risk factors for recurrence were multiplicity, size > 3 cm and association with CIS. The main risk factor for progression was grade 3 (OR 19.9). Grade 3 and association with CIS were found to increase mortality risk. On the basis of this data, we grouped tumors according to low-, middle-, and high-risk, and established our proposed treatment and followup for each group.CONCLUSIONS:
This multivariate analysis of a homogeneous cohort of 1,529 primary superficial bladder tumor cases allowed vs to determine risk groups for treatment and followup.
