Perioperative Systemic Therapies in Muscle-Invasive Bladder Cancer (GUARDIANS)
Sponsor: LMU Klinikum
Summary
This is a multicenter, non-interventional, prospective and retrospective observational patient registry study of adults with muscle-invasive bladder cancer receiving perioperative systemic therapy as part of routine clinical care. The registry includes patients treated with perioperative systemic therapies such as Enfortumab Vedotin plus Pembrolizumab as well as cisplatin-based combinations including Gemcitabine/Cisplatin/Durvalumab and other standard perioperative treatment approaches in the neoadjuvant and adjuvant setting. The study aims to evaluate real-world feasibility, treatment tolerability, pathologic response, and oncologic outcomes of perioperative systemic treatment strategies. Key outcomes include event-free survival (EFS), pathologic complete response (pCR), pathologic downstaging, disease-free survival (DFS), overall survival (OS), perioperative complications, and treatment-related adverse events. Patient-reported neurotoxicity symptoms will also be assessed using standardized neuropathy questionnaires. All treatments, surgeries, and follow-up procedures are performed according to routine clinical practice. No study-specific interventions are assigned. Clinical data are collected pseudonymized through participating GUARDIANS centers using standardized electronic case report forms. Both prospective and retrospective data collection are included.

Perioperative Systemic Therapy Registry
Observational registry of patients with muscle-invasive bladder cancer receiving perioperative systemic therapy as part of routine clinical care. Treatments are not assigned by protocol and may include Enfortumab Vedotin plus Pembrolizumab, Gemcitabine/Cisplatin/Durvalumab, cisplatin-based chemotherapy, immunotherapy, and other standard neoadjuvant or adjuvant treatment approaches. All therapeutic decisions are made independently by treating physicians according to local standard of care.
