Abstract
BACKGROUND/AIM: In the CheckMate 214 trial, approximately 40% of patients with advanced renal cell carcinoma (aRCC) treated with nivolumab plus ipilimumab (NIVO + IPI) achieved long-term survival and a durable response to treatment. However, about 20% of patients experienced early disease progression (EDP). This retrospective study aimed to identify predictive factors for EDP among patients with aRCC treated with NIVO + IPI. PATIENTS AND METHODS: We retrospectively analyzed clinical information from patients with aRCC, 19 patients in the EDP group and 40 patients in the control disease group, all of whom were treated with NIVO + IPI at Kurume University Hospital between September 2018 and February 2024. RESULTS: The EDP group exhibited significantly worse progression-free survival and overall survival compared to the control disease group. Multivariate analyses revealed that a performance states (PS) ≥2 (p=0.0312) and the presence of bone metastases (p=0.0374) were independent predictors of EDP. CONCLUSION: Treatment with NIVO + IPI in patients with aRCC who have a poor PS or bone metastases may be linked to a high risk of EDP.
