Popis | Background The benefit of immune checkpoint inhibitors (ICIs) for poor performance status patients with advanced urothelial carcinoma (UC) remains unknown. Objective In the present sub-analysis of the ARON-2 study, we investigated the role of pembrolizumab for advanced UC patients with ECOG (Eastern Cooperative Oncology Group) performance status (ECOG-PS) 2. Patients and Methods Patients aged >= 18 years with a cytologically and/or histologically confirmed diagnosis of advanced UC progressing or recurring after platinum-based therapy and treated with pembrolizumab between 1 January 2016 to 1 April 2024 were included. In this sub-analysis we focused on patients with ECOG-PS 2. Results We included 1,040 patients from the ARON-2 dataset; of these, 167 patients (16%) presented an ECOG-PS 2. The median overall survival (OS) was 14.8 months (95% confidence interval (CI) 12.5-16.1) in the overall study population, 18.2 months (95% CI 15.8-22.2) in patients with ECOG-PS 0-1, and 3.7 months (95% CI 3.2-5.2) in subjects with ECOG-PS 2 (p < 0.001). The median progression-free survival (PFS) in the overall study population was 5.3 months (95% CI 4.3-97.1), 6.2 months (95% CI 5.5-97.1) in patients with ECOG-PS 0-1, and 2.8 months (95% CI 2.1-3.4) in patients with ECOG-PS 2. Among the latter, liver metastases and progressive disease during first-line therapy were significant predictors of OS at both univariate and multivariate analyses. For PFS, univariate and multivariate analyses showed a prognostic role for lung metastases, liver metastases, and progressive disease during first-line therapy. Conclusions This large real-world evidence study suggests the effectiveness of second-line pembrolizumab for mUC patients with poor performance status. The presence of liver metastases and progressive disease during first-line therapy is associated with worse clinical outcomes and, thus, should be taken into account when making treatment decisions in clinical practice. |
