Résumé
Sunitinib is a multiple tyrosine kinase receptor inhibitor that is approved for the treatment of metastatic renal cell carcinoma (RCC). However, neither an appropriate dose nor dosing schedule of sunitinib has yet been established for patients with metastatic RCC who are on hemodialysis. Here, we report on two hemodialysis patients who received sunitinib to treat metastatic RCC. Sunitinib was planned to be administered at a dosage of 25 mg/d for 4 of every 6 weeks. Although sunitinib toxicity was manageable in one patient, disease progression occurred after 4 months of treatment. In the second patient, acute pulmonary edema, caused by uncontrolled hypertension, developed on the 15th day of sunitinib therapy and the drug had to be discontinued. Sunitinib is thus not well tolerated in a hemodialysis setting. Close monitoring of toxicity and dose manipulation may be required if such therapy is attempted.
