Purpose: It is known that 30% of clear cell renal cell carcinomas (ccRCC) will develop progressive disease after surgical treatment. These patients with high-risk ccRCC require adjuvant therapy after nephrectomy or resection of metastases. The article presents an overview of the results of recent studies in adjuvant therapy.
Methods: We analyzed the results of randomized trials of targeted therapy and checkpoint inhibitors in high-risk ccRCC patients.
Results: Targeted therapy did not significantly reduce this risk or/and did not affect overall survival. Three randomized studies investigating nivolumab, ipilimumab, and atezolizumab in the adjuvant setting also failed without improving disease-free survival. Pembrolizumab had a significant impact on the disease-free survival in the entire population, with the greatest effect in patients after metastasectomy, but mature overall survival data are not yet available.
Conclusions: In conclusion, it must be noted that, at present, it has not been possible to achieve magnificent success in adjuvant therapy of RCC in patients at high risk of relapse after surgical treatment. There remains hope for adjuvant pembrolizumab, which has been used for high-risk population including patients with removed metastases who may benefit more from therapy.
