Context:
The expanding armamentarium of agents for the therapy of advanced clear cell renal cell carcinoma (RCC) warrants further investigation of optimal patient selection.
Objective:
To analyze the second and subsequent line of targeted therapies for advanced RCC while integrating clinical and molecular markers and imaging.
Evidence Acquisition:
Data were acquired from research published in peer-reviewed literature or presented at major conferences.
Evidence Synthesis:
Following first-line vascular endothelial growth factor (VEGF) inhibitors, second-line therapy with everolimus, a mammalian target of rapamycin inhibitor, and axitinib, a VEGF receptor tyrosine kinase inhibitor, have demonstrated benefits in progression-free survival (PFS). Sorafenib, pazopanib, and axitinib have demonstrated extension of PFS following cytokines. Optimal patient selection based on biomarkers is undergoing investigation. Clinical trials evaluating novel agents and combinations should be preferred.
Conclusions:
Currently, the sequence of therapy is based on patient and physician decision, which may be influenced by comorbidities and toxicity profiles.
Insights
For advanced clear cell renal cell carcinoma (RCC), everolimus and axitinib show benefits in progression-free survival (PFS) after first-line vascular endothelial growth factor (VEGF) inhibitors. Patient selection for targeted therapies is key.
Area of Science:
- Oncology
- Pharmacology
- Translational Medicine
Background:
- Advanced clear cell renal cell carcinoma (RCC) treatment has expanded, necessitating optimal patient selection strategies.
- Investigating second and subsequent line targeted therapies for advanced RCC is crucial.
Purpose of the Study:
- To analyze second and subsequent line targeted therapies for advanced RCC.
- To integrate clinical, molecular, and imaging markers for patient selection.
- To review current treatment paradigms and future directions.
Main Methods:
- Systematic review of peer-reviewed literature.
- Analysis of data presented at major scientific conferences.
- Integration of clinical, molecular, and imaging data.
Main Results:
- Everolimus and axitinib demonstrated improved progression-free survival (PFS) as second-line therapies after vascular endothelial growth factor (VEGF) inhibitors.
- Sorafenib, pazopanib, and axitinib extended PFS following cytokine therapy.
- Biomarker-based patient selection for targeted RCC therapy is under investigation.
Conclusions:
- Current treatment sequencing for advanced RCC relies on patient and physician decisions.
- Comorbidities and toxicity profiles influence therapeutic choices.
- Clinical trials for novel agents and combinations are recommended.

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...
