Cost of Bladder Cancer Care: A Single-center Comparison of Radical Cystectomy and Trimodal Therapy

Radical cystectomy and trimodal therapy are both accepted options in the management of muscle-invasive bladder cancer. As such, we sought to evaluate the micro-level costs associated with both modalities.

All patients undergoing trimodal therapy or radical cystectomy for primary treatment of urothelial muscle-invasive bladder cancer at a single academic center between 2008 and 2012 were included. Direct costs associated with each phase of a patient's clinical course were collected from the hospital's financial department, and physician costs were calculated based on the provincial fee schedule. Costs of radiation treatments were derived from previously published literature.

A total of 137 patients were included. The mean (±SD) patient age was 69 (±12) years. Overall, 89 (65%) patients underwent radical cystectomy and 48 (35%) were treated with trimodal therapy. The radical cystectomy group had higher rates of cT3/T4 compared to those in the trimodal therapy group (51% vs 26%, P < .001). The median cost in the treatment phase for radical cystectomy was $30,577 (IQR: $23,908-$38,837) vs $18,979 ($17,271-$23,519) for trimodal therapy (P < .001). There was no significant difference between treatment groups with respect to cost of diagnosis or workup. However, the cost of follow-up care was numerically higher for patients undergoing trimodal therapy compared to radical cystectomy ($3,096/y vs $1,974/y, P = .09).

In appropriately selected patients with muscle-invasive bladder cancer trimodal therapy costs are not prohibitive and are lower than in radical cystectomy. With increasing follow-up time after primary treatment, the cost difference between modalities may be mitigated by the need for bladder surveillance and salvage therapy in the trimodal therapy cohort.
