[The Pharmacokinetics and Safety of Oxaliplatin in a Hemodialysis Patient Treated with Mfolfox6 Therapy].

A postoperative rectum cancer patient with lung metastasis undergoing hemodialysis was treated with mFOLFOX6 therapy. The primary dose of oxaliplatin (L-OHP) ranged from 60 mg/m(2) to 85 mg/m(2), and adverse reactions and serum platinum concentration were monitored. The free platinum concentration (f-Pt), was eliminated efficiently using dialysis. The patient was tolerant of L-OHP doses of 60 mg/m(2) and 70 mg/m(2), but grade 2 neutropenia and grade 3 hemoglobin decrease developed with an L-OHP dose of 85 mg/m(2). The f-Pt after hemodialysis was higher than that before hemodialysis with a dose of 85 mg/m(2). But even with an 85 mg/m(2) dose, mFOLFOX6 therapy could be continued by extending the dosing interval. The monitoring of serum platinum concentrations, as well as therapeutic monitoring based on pharmacokinetics, contributes to safety management of cancer chemotherapy.
