[Immunotherapy in bladder cancer-quo vadis? Update on current trials and developments].

Great advances have been made for the treatment of urothelial carcinoma by the introduction of checkpoint inhibitors (CPI). Single-agent immunotherapy with CPIs has been approved for patients with metastatic or locally advanced inoperable urothelial carcinoma who have either progressed during or after platinum-based chemotherapy or who are cisplatin-ineligible. For cisplatin-ineligible patients, approval is restricted to patients with high programmed cell death ligand 1 (PD-L1) expression. For patients with nonmuscle invasive bladder cancer (NMIBC) or patients with muscle invasive bladder cancer (MIBC) who receive curative therapy, no CPIs have received approval in Germany.

To provide an overview of the current landscape of immunotherapy in patients with urothelial carcinoma.

Summary of the therapeutic landscape and resulting challenges based on currently published data using a PubMed search.

In the treatment of metastatic or inoperable urothelial carcinoma, CPIs represent standard treatment. Depending on the results of currently performed trials, an extension of its use to the perioperative setting (neoadjuvant/adjuvant) and to patients with Bacillus Calmette Guérin (BCG) unresponsive NMIBC in the near future is currently being discussed.

Immuno-oncologic treatment using CPIs has become an integral part of the management of patients with advanced bladder cancer. For biomarker-based patient selection and combination therapies, there is an urgent need for further investigations within clinical trial protocols.
