Context: The first European Association of Urology (EAU) guidelines on bladder cancer were published in 2002 [1]. Since then, the guidelines have been continuously updated.
Objective: To present the 2013 EAU guidelines on non-muscle-invasive bladder cancer (NMIBC). Evidence acquisition: Literature published between 2010 and 2012 on the diagnosis and treatment of NMIBC was systematically reviewed.
Previous guidelines were updated, and the levels of evidence and grades of recommendation were assigned. Evidence synthesis: Tumours staged as Ta, T1, or carcinoma in situ (CIS) are grouped as NMIBC.
Diagnosis depends on cystoscopy and histologic evaluation of the tissue obtained by transurethral resection (TUR) in papillary tumours or by multiple bladder biopsies in CIS. In papillary lesions, a complete TUR is essential for the patient's prognosis.
Where the initial resection is incomplete, where there is no muscle in the specimen, or where a high-grade or T1 tumour is detected, a second TUR should be performed within 2-6 wk. The risks of both recurrence and progression may be estimated for individual patients using the EORTC scoring system and risk tables.
The stratification of patients into low-, intermediate-, and high-risk groups is pivotal to recommending adjuvant treatment. For patients with a low-risk tumour, one immediate instillation of chemotherapy is recommended.
Patients with an intermediate-risk tumour should receive one immediate instillation of chemotherapy followed by 1 yr of full-dose bacillus Calmette-Guerin (BCG) intravesical immunotherapy or by further instillations of chemotherapy for a maximum of 1 yr. In patients with high-risk tumours, full-dose intravesical BCG for 1-3 yr is indicated.
In patients at highest risk of tumour progression, immediate radical cystectomy should be considered. Cystectomy is recommended in BCG-refractory tumours.
