Improving outcomes in metastatic clear cell renal cell carcinoma by sequencing therapy

Abstract:
Targeted agents have substantially improved outcomes in metastatic clear cell renal cell carcinoma. However, due to multiple mechanisms of evasive resistance, almost all patients progress at some point and may require subsequent therapies. Various agents have been explored after failure of first-line treatment in randomized clinical trials. However, so far few questions about the optimal sequence have been answered. Both everolimus and axitinib have been considered standard of care after failure of first-line VEGF-TKI; sorafenib has been proposed as an additional option. In clinical practice, several factors may influence the choice of subsequent treatment: these include considerations on appropriate drug exposure in first-line, gained insights on prognostic and predictive factors as well as mechanisms of resistance. Once the decision in second-line has been made and treatment has been initiated, treating physicians may already be challenged by the question of what to offer in third- and later lines. Treatment beyond second-line treatment isn't supported by strong evidence, and at this stage of disease, retrospective reports on rechallenge may help to guide decisions. In addition, local treatment approaches including metastasectomy and stereotactic radiosurgery may help to optimize outcomes in all treatment lines.
Insights
For metastatic clear cell renal cell carcinoma, resistance to targeted therapies is common. Optimal sequencing of subsequent treatments like everolimus and axitinib remains challenging after initial therapy failure.
Area of Science:
- Oncology
- Medical treatment
Background:
- Targeted agents have improved outcomes in metastatic clear cell renal cell carcinoma (ccRCC).
- Evasive resistance mechanisms lead to disease progression, necessitating further therapies.
- Optimal sequencing of treatments after first-line therapy failure in ccRCC is not well-established.
Purpose of the Study:
- To review current understanding of treatment sequencing in metastatic ccRCC.
- To discuss factors influencing the choice of subsequent therapies.
- To explore options for treatment beyond second-line therapy.
Main Methods:
- Review of randomized clinical trials and clinical practice considerations.
- Analysis of prognostic and predictive factors, and resistance mechanisms.
- Discussion of retrospective data on treatment rechallenge and local therapies.
Main Results:
- Everolimus and axitinib are standard after first-line VEGF-TKI failure; sorafenib is an option.
- Treatment decisions are influenced by prior drug exposure, prognostic factors, and resistance.
- Evidence for treatment beyond second-line is limited, with retrospective data guiding choices.
Conclusions:
- Sequencing targeted therapies in metastatic ccRCC requires careful consideration of multiple factors.
- Treatment beyond second-line is challenging and may involve rechallenge or local approaches.
- Optimizing outcomes in advanced ccRCC involves strategic sequencing and individualized treatment plans.
