Pembrolizumab outperforms tyrosine kinase inhibitors as adjuvant treatment in patients with high-risk renal cell carcinoma after nephrectomy.

We determined the oncologic outcomes and safety profiles of adjuvant immune checkpoint inhibitors (ICIs) compared to adjuvant tyrosine kinase inhibitors (TKIs) in patients at high risk after nephrectomy for clinically nonmetastatic renal cell carcinoma (RCC). Network meta-analyses were conducted for disease-free survival (DFS), overall survival (OS), and adverse events (AEs) with placebo as the common comparator arm. Six trials (KEYNOTE-564, S-TRAC, ASSURE, PROTECT, ATLAS, and SORCE) were included in our analysis. Compared to placebo, both pembrolizumab (hazard ratio [HR] 0.68, 95% confidence interval [CI] 0.51-0.92) and pazopanib 800 mg (HR 0.69, 95% CI 0.49-0.97) were significantly associated with better DFS. Adjuvant pembrolizumab (HR 0.54, 95% CI 0.30-0.97) was significantly associated with better OS compared to TKIs (HR 0.93, 95% CI 0.83-1.04). Analysis of treatment ranking revealed that pembrolizumab was the best treatment with regard to both DFS and OS and had the lowest likelihood of any-grade and high-grade AEs in comparison to TKIs. The superior oncologic benefit of pembrolizumab and its better toxicity profile support it as the new standard of care in the adjuvant setting for nephrectomy patients at high risk of RCC relapse. PATIENT SUMMARY: For patients with kidney cancer at high risk of relapse after surgical removal of their kidney, postoperative therapy with the immune checkpoint inhibitor pembrolizumab offers the best risk/benefit ratio.
