A 60-year-old male with chronic renal failure undergoing hemodialysis was treated with combination chemotherapy with carboplatin and etoposide against stage IV adenocarcinoma of the lung. Three hundred mg/m2 of carboplatin on day 1, and 50 mg/m2 of etoposide on days 1 and 3 were injected intravenously before hemodialysis. Pharmacokinetic results revealed that carboplatin was dialyzed. No severe side effects were observed. These observations suggest that combination chemotherapy with carboplatin and etoposide seemed to be applicable to the patients with chronic renal failure undergoing hemodialysis.
