New Italian guidelines on bladder cancer, based on the World Health Organization 2004 classification

OBJECTIVE To provide evidence‐based recommendations on bladder cancer management METHODS A multidisciplinary guideline panel composed of urologists, medical oncologists, radiotherapists, general practitioners, radiologists, epidemiologists and methodologists conducted a structured review of previous reports, searching the Medline database from 1 January 2004 to 31 December 2008. The milestone papers published before January 2004 were accepted for analysis. The level of evidence and the grade of the recommendations were established using the GRADE system. RESULTS In all, 15 806 references were identified, 1940 retrieved, 1712 eliminated (specifying the reason for their elimination) and 971 included in the analysis, as well as 241 milestone reports. A consensus conference held to discuss the discrepancies between the scientific evidence and the clinical practice was then attended by 122 delegates of various specialities. CONCLUSION Recommendations on bladder cancer management are provided.
