Abstract:
Adjuvant and neoadjuvant therapies that reduce the risk of renal cell carcinoma (RCC) recurrence remain an area of unmet need. Advances have been made in metastatic RCC recently by leveraging PD-1/PD-L1 immune checkpoint inhibitors (ICIs). These agents are currently being investigated in the adjuvant and neoadjuvant settings to determine if intervention early in the disease trajectory offers a clinically meaningful benefit. While a disease-free survival benefit has been demonstrated with pembrolizumab, results from other ICI studies have not been positive to date. More mature data from these studies are needed to determine whether there is a survival benefit to ICIs in the curative-intent setting. The success of ICIs has also ushered a new wave of studies combining ICIs with other agents such as targeted therapies and vaccines, which are in early stages of investigation. We review the current state of adjuvant/neoadjuvant therapy in RCC and highlight opportunities for ongoing study.
Insights
Adjuvant and neoadjuvant therapies for renal cell carcinoma (RCC) are under investigation. While some immune checkpoint inhibitors show promise, more data is needed to confirm survival benefits in early-stage disease.
Area of Science:
- Oncology
- Nephrology
- Immunotherapy
Background:
- Adjuvant and neoadjuvant therapies for renal cell carcinoma (RCC) are critical for reducing recurrence risk, representing an unmet clinical need.
- Recent advancements in metastatic RCC have involved PD-1/PD-L1 immune checkpoint inhibitors (ICIs).
- Investigating ICIs in early-stage RCC (adjuvant and neoadjuvant settings) aims to determine their clinical benefit in disease trajectory.
Approach:
- Reviewing current adjuvant/neoadjuvant therapies for RCC.
- Analyzing the efficacy of immune checkpoint inhibitors (ICIs) in early-stage RCC.
- Highlighting ongoing research and future opportunities, including combinations of ICIs with targeted therapies and vaccines.
Key Points:
- Pembrolizumab has demonstrated a disease-free survival benefit in the adjuvant setting for RCC.
- Results from other ICI studies in the adjuvant/neoadjuvant settings have not yet shown significant benefits.
- Mature survival data is required to establish the overall survival benefit of ICIs in the curative-intent setting for RCC.
Conclusions:
- Immune checkpoint inhibitors (ICIs) represent a promising avenue for adjuvant and neoadjuvant therapy in renal cell carcinoma (RCC).
- Further research and mature data are essential to confirm the long-term efficacy and survival benefits of ICIs in early-stage RCC.
- Combination strategies involving ICIs with other therapeutic agents are emerging and warrant further investigation.
