Background:
Sunitinib and sorafenib are small-molecule tyrosine kinase inhibitors with known antitumor activity in advanced renal cell carcinoma.
Materials And Methods:
We retrospectively assess the response and tolerance of elderly patients with renal cell carcinoma to these two agents. Data of patients aged ≥70years receiving sorafenib or sunitinib at the Centre Léon Bérard were analyzed. Forty-eight patients received sorafenib or sunitinib as a first line treatment, 8 received sorafenib followed by sunitinib and 4 received the reverse sequence. Objective responses (ORs), stable disease (SD), toxicity, overall survival (OS) and progression-free survival (PFS) were reported.
Results:
Sorafenib and sunitinib achieved similar OR+SD rates (79% vs. 71% respectively). Median PFS was 6months in first-line sorafenib treated patients and 5months in the sunitinib group. Median OS was 16months in first-line sorafenib-treated patients and 15months in the sunitinib group. In patients receiving sorafenib followed by sunitinib, median PFS was 11.5months, and median OS was 13.1months. With the reverse sequence, median PFS was 8.1months and median OS was 15months. Treatment modifications were more frequent in sunitinib-treated patients, in first or second line (75% vs. 50%). Limitations are the retrospective design of the study and the small number of patients.
Conclusion:
First-line sunitinib and sorafenib seem equally efficient in elderly patients treated for advanced renal carcinomas, but sunitinib is less well tolerated. Sequential treatment with sorafenib followed by sunitinib seems to be better tolerated. These results should be confirmed in a larger prospective study.
Insights
First-line sunitinib and sorafenib show similar effectiveness in elderly patients with advanced renal cell carcinoma. However, sunitinib is less tolerated, and sequential therapy may improve tolerance.
Area of Science:
- Oncology
- Pharmacology
Background:
- Sunitinib and sorafenib are small-molecule tyrosine kinase inhibitors with established antitumor activity.
- Advanced renal cell carcinoma (RCC) is a significant clinical challenge.
Purpose of the Study:
- To assess the response and tolerance of elderly patients (≥70 years) with advanced renal cell carcinoma to sunitinib and sorafenib.
- To compare first-line treatment efficacy and sequential treatment outcomes.
Main Methods:
- Retrospective analysis of 60 elderly patients with advanced RCC treated with sorafenib or sunitinib.
- Evaluation of objective responses (OR), stable disease (SD), toxicity, overall survival (OS), and progression-free survival (PFS).
Main Results:
- Similar OR+SD rates for first-line sorafenib (79%) and sunitinib (71%).
- Median PFS: 6 months (sorafenib) vs. 5 months (sunitinib). Median OS: 16 months (sorafenib) vs. 15 months (sunitinib).
- Sequential sorafenib then sunitinib showed median PFS of 11.5 months and OS of 13.1 months; reverse sequence had median PFS of 8.1 months and OS of 15 months. Sunitinib required more treatment modifications.
Conclusions:
- First-line sunitinib and sorafenib demonstrate comparable efficacy in elderly advanced RCC patients.
- Sunitinib is associated with lower tolerance compared to sorafenib.
- Sequential treatment with sorafenib followed by sunitinib appears better tolerated and warrants further investigation in prospective studies.

Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs.
