The incidence of immune-related adverse events (irAEs) and their association with clinical outcomes in advanced renal cell carcinoma and urothelial carcinoma patients treated with immune checkpoint inhibitors: A systematic review and meta-analysis. Cancer Treat Rev 2024; 129:102787. [PMID: 38905806 DOI: 10.1016/j.ctrv.2024.102787] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2024] [Revised: 06/10/2024] [Accepted: 06/11/2024] [Indexed: 06/23/2024]
Abstract
BACKGROUND This study aimed to summarize the occurrence of immune-related adverse events (irAEs) and further evaluate their association with clinical outcomes in patients with advanced renal cell carcinoma (RCC) and urothelial carcinoma (UC) treated with immune checkpoint inhibitors (ICIs). METHODS A comprehensive search of PubMed, Embase, and the Cochrane Library up to December 2023 was conducted to identify eligible studies. The details of irAEs and data regarding their correlation with clinical outcomes were extracted. R software was used for meta-analysis. RESULTS A total of 27 studies involving 6148 patients with RCC or UC were included. The pooled overall incidence for any-grade and grade ≥ 3 irAEs was 44.2 % (95 % CI: 38.1 %-50.5 %) and 15.7 % (95 % CI: 11.4 %-21.1 %), respectively. Compared to those without any irAEs, patients with irAEs showed improved PFS (HR = 0.44, 95 % CI: 0.35-0.56, p < 0.01) and OS (HR = 0.47, 95 % CI: 0.42-0.51, p < 0.01), as well as higher ORR (OR = 3.59, 95 % CI: 3.01-4.29, p < 0.01) and DCR (OR = 4.23, 95 % CI: 3.06-5.84, p < 0.01). Subgroup analysis indicated that clinical outcome improvements were associated with the occurrence of irAEs, regardless of tumor type or ICI agent. Notably, patients with cutaneous irAEs, thyroid dysfunction, and grade ≤ 2 irAEs had a higher probability to achieve better survival benefits from ICI-based therapy, while pulmonary irAEs and grade ≥ 3 irAEs seemed to have a negative impact on OS. Additionally, systemic glucocorticoids administration did not affect survival outcomes. CONCLUSION Our findings suggest that the occurrence of irAEs could be considered as a potential prognostic factor for predicting the efficacy of ICIs in patients with advanced RCC and UC.

Abstract
Immunotherapies, such as immune checkpoint inhibitors, have heralded impressive progress for patient care in renal cell carcinoma (RCC). Despite this success, some patients' disease fails to respond, and other patients experience significant side effects. Thus, development of biomarkers is needed to ensure that patients can be selected to maximize benefit from immunotherapies. Improving clinicians' ability to predict which patients will respond to immunotherapy and which are most at risk of adverse events - namely through clinical biomarkers - is indispensable for patient safety and therapeutic efficacy. Accordingly, an evolving suite of therapeutic biomarkers continues to be investigated. This review discusses biomarkers for immunotherapy in RCC, highlighting current practices and emerging innovations, aiming to contribute to improved outcomes for patients with RCC.
