Title: Use of restaging bladder tumor resection for bladder cancer among Medicare beneficiaries.

Journal: Urology 78(6):1345-9

Date: 2011 Dec

Abstract: OBJECTIVE: To evaluate the use and effectiveness of restaging bladder tumor resection using population-based data. Restaging bladder tumor resection improves staging accuracy and the response to intravesical therapy. However, its use outside of a tertiary care setting, and its subsequent clinical implications, are unknown. METHODS: We identified 62 016 patients diagnosed with bladder cancer between 1992 and 2005 using SEER-Medicare data. Restaging bladder tumor resection was defined as 2 or more resections occurring within 60 days of diagnosis. Using multivariable models, we assessed the relationship between the use of restaging resection and cancer-specific survival. RESULTS: Restaging resection was performed in only 3064 (4.9%) of newly diagnosed bladder cancer patients, but was most common among those with high grade (7.7% vs 2.0% in low grade, P < .001) and stage (8.8% in T2 vs 2.8% in Ta/Tis, P < .001) disease. Compared to patients with muscle-invasive cancers who did not undergo restaging at diagnosis, restaging resection was associated with improved 5-year cancer-specific mortality among pathologically staged patients (20.4% vs 28.0%, P = .02), while clinically staged patients trended toward improved mortality (28.2% vs 31.9%, P = .07). CONCLUSION: Restaging transurethral resection for bladder cancer is relatively uncommon and associated with improved survival among patients with muscle invasive bladder cancer. Greater use of restaging warrants further investigation as a simple means of improving outcomes among patients suspected of having muscle invasive disease.
