Bladder neck involvement in pathological stage pT4 radical prostatectomy specimens is not an independent prognostic factor
Urinary Bladder Neck Obstruction
Stage pT4 disease comprises a heterogeneous group of tumors with various pathological features and inconsistent outcomes. Assigning the pT4 stage to cases of microscopic bladder neck invasion provides no independent ability for predicting disease progression after adjusting for other adverse disease features. Due to this and previously reported data the definition of stage pT4 disease should be modified in the next version of the TNM staging system.
