Role of a Modified Urothelium Immune Prognostic Index in Patients With Metastatic Urothelial Carcinoma Treated With Anti-PD-1/PD-L1-Based Therapy.

ABSTRACT: Introduction: The use of antibodies against programmed death receptor-1 (PD-1) and its ligand (PD-L1) has improved survival in metastatic urothelial carcinoma (mUC) patients. However, reliable and convenient biomarkers of early responses and outcomes are still lacking. Materials and Methods: We retrospectively screened mUC patients who received anti-PD-1/PD-L1-based therapy at our institute. A modified urothelium immune prognostic index (mUIPI) based on the neutrophil-to-lymphocyte ratio (NLR) and lactate dehydrogenase (LDH) was developed to characterize the three groups as good, intermediate, and poor mUIPI. Major observations were progression-free survival (PFS), overall survival (OS), and disease control rate (DCR). Results: We identified 52 mUC patients with a medi
