SEOM Clinical Guidelines for the Treatment of Invasive Bladder Cancer

The purpose of this article is to provide updated recommendations for the diagnosis and treatment of muscle- invasive and metastatic bladder cancer. The diagnosis of muscle-invasive bladder cancer is made by transurethral resection and following histopathologic evaluation. Invasive bladder cancer should be staged according to the UICC system. Patients with confirmed muscle-invasive bladder cancer should be staged by computed tomography scans of the chest, abdomen and pelvis. Radical cystectomy is the treatment of choice for both sexes and lymph node dissection should be an integral part of cystectomy. In muscle- invasive bladder cancer (cT2-4aN0M0) patients with good performance status (PS 0-1) and correct renal function, neoadjuvant chemotherapy should be recommended. Adjuvant chemotherapy is widely used in high-risk patients with pathologic stage T3 or T4 and/or positive nodes and within clinical trials. Multimodality bladder-preserving treatment in localised disease is currently regarded only as an alternative in selected, well informed and compliant patients for whom cystectomy is not considered for clinical or personal reasons. In metastatic disease, the first-line treatment for patients is cisplatin-containing combination chemotherapy. Recently, vinflunine has been approved in Europe for second-line treatment and is an option for second-line therapy in patients progressing to first-line platinum-based chemotherapy.
