Abstract:
Because metachronous metastatic disease will develop in 20% to 40% of patients with presumed localized renal cell carcinoma (RCC) treated surgically, research is focused on neoadjuvant and adjuvant systemic therapy, to improve disease-free and overall survival. Neoadjuvant therapies trialed include anti-vascular endothelial growth factor (VEGF) tyrosine kinase inhibitor (TKI) agents, or combination therapies (immunotherapy with TKI), and aim to improve resectability of locoregional RCC. Adjuvant therapies trialed include cytokines, anti-VEGF TKI agents, or immunotherapy. These therapeutics can facilitate the surgical extirpation of the primary kidney tumor in the neoadjuvant setting and improve disease-free survival in the adjuvant setting.
Insights
Systemic therapies, including anti-VEGF tyrosine kinase inhibitors (TKIs) and immunotherapy, are being researched for localized renal cell carcinoma (RCC). These treatments aim to improve surgical outcomes and patient survival rates.
Area of Science:
- Oncology
- Nephrology
- Pharmacology
Background:
- Metachronous metastatic disease affects 20-40% of localized renal cell carcinoma (RCC) patients post-surgery.
- Improving disease-free and overall survival in RCC necessitates novel therapeutic strategies.
Purpose of the Study:
- To investigate the role of neoadjuvant and adjuvant systemic therapies in enhancing outcomes for localized renal cell carcinoma (RCC).
- To evaluate the efficacy of anti-vascular endothelial growth factor (VEGF) tyrosine kinase inhibitors (TKIs) and immunotherapy in RCC management.
Main Methods:
- Review of neoadjuvant therapies including anti-VEGF TKI agents and combination therapies (immunotherapy with TKI).
- Analysis of adjuvant therapies such as cytokines, anti-VEGF TKI agents, and immunotherapy.
Main Results:
- Neoadjuvant therapies aim to improve the resectability of locoregional RCC.
- Adjuvant therapies have shown potential in improving disease-free survival post-surgery.
Conclusions:
- Systemic therapies offer a promising approach to improve surgical extirpation and survival in RCC patients.
- Further research into neoadjuvant and adjuvant treatments is crucial for optimizing RCC patient outcomes.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
