SEOM clinical guideline for treatment of muscle-invasive and metastatic urothelial bladder cancer (2018).

ABSTRACT: The goal of this article is to provide recommendations about the management of muscle-invasive (MIBC) and metastatic bladder cancer. New molecular subtypes of MIBC are associated with specific clinical-pathological characteristics. Radical cystectomy and lymph node dissection are the gold standard for treatment and neoadjuvant chemotherapy with a cisplatin-based combination should be recommended in fit patients. The role of adjuvant chemotherapy in MIBC remains controversial; its use must be considered in patients with high-risk who are able to tolerate a cisplatin-based regimen, and have not received neoadjuvant chemotherapy. Bladder-preserving approaches are reasonable alternatives to cystectomy in selected patients for whom cystectomy is not contemplated either for clinical or personal reasons. Cisplatin-based combination chemotherapy is the standard first-line protocol for metastatic disease. In the case of unfit patients, carboplatin-gemcitabine should be considered the preferred first-line chemotherapy treatment option, while pembrolizumab and atezolizumab can be contemplated for individuals with high PD-L1 expression. In cases of progression after platinum-based therapy, PD-1/PD-L1 inhibitors are standard alternatives. Vinflunine is another option when anti-PD-1/PD-L1 therapy is not possible. There are no data from randomized clinical trials regarding moving on to immuno-oncology agents.

Project description:Non-muscle invasive bladder cancer (NMIBC) is a major type of bladder cancer with a high incidence worldwide, resulting in a great disease burden. Treatment and surveillance are the most important part of NIMBC management. In 2018, we issued “Treatment and surveillance for non-muscle-invasive bladder cancer in China: an evidence-based clinical practice guideline”. Since then, various studies on the treatment and surveillance of NMIBC have been published. There is a need to incorporate these materials and also to take into account the relatively limited medical resources in primary medical institutions in China. Developing a version of guideline which takes these two issues into account to promote the management of NMIBC is therefore indicated. We formed a working group of clinical experts and methodologists. Through questionnaire investigation of clinicians including primary medical institutions, 24 clinically concerned issues, involving transurethral resection of bladder tumor (TURBT), intravesical chemotherapy and intravesical immunotherapy of NMIBC, and follow-up and surveillance of the NMIBC patients, were determined for this guideline. Researches and recommendations on the management of NMIBC in databases, guideline development professional societies and monographs were referred to, and the European Association of Urology was used to assess the certainty of generated recommendations. Finally, we issued 29 statements, among which 22 were strong recommendations, and 7 were weak recommendations. These recommendations cover the topics of TURBT, postoperative chemotherapy after TURBT, Bacillus Calmette–Guérin (BCG) immunotherapy after TURBT, combination treatment of BCG and chemotherapy after TURBT, treatment of carcinoma in situ, radical cystectomy, treatment of NMIBC recurrence, and follow-up and surveillance. We hope these recommendations can help promote the treatment and surveillance of NMIBC in China, especially for the primary medical institutions.
