• The purpose of this study was to evaluate, from the perspective of the Quebec health system, the cost and cost-efficacy of using NMP22 compared with the currently recommended monitoring procedure following a transurethral resection of a bladder tumor (TURBT). This evaluation was based on results from the study by Soloway, et al. It was performed using a decision analysis technique which compared a follow-up modality using NMP22 with the conventional follow-up monitoring procedure for the first 6 months after an initial transurethral resection of a bladder tumor. Each routine cystoscopy and cytology costs a total of $155. For the 6 months following initial TURBT, the cost for standard follow-up monitoring totaled $311, while the cost for the NMP22 monitoring modality was $257. On average, using NMP22 would have saved $55 per patient during the first 6 months of follow-up, resulting in a cost saving of approximately 18%. As well, 64.3% of patients would have undergone only one cystoscopy during the 6 month period, instead of the two done using the conventional modality. The trade-off for using NMP22 is that some patients would have a 3 month delay before diagnosis of a recurrence. This would occur in 8.9% of patients. NMP22 is less expensive than conventional monitoring follow-up of bladder cancer, and it can decrease patient discomfort by reducing the need for cystoscopy. Implementing it as routine follow-up monitoring should be considered, particularly for patients with low-grade tumors.
