title: [Pharmacokinetics of high-dose melphalan (200 mg/m2) in a case of total renal insufficiency].
abstract: The pharmacokinetics of the alkylating agent melphalan was determined in a dialysed patient, 30 years old, who underwent unilateral orchidectomy for a malignant testicular tumor. Melphalan was included in a polychemotherapy treatment with eight 1-h infusions of 230 mg of etoposide (VP 16), then one 5-min infusion of 370 mg of melphalan (200 mg/m2) followed by autologous bone marrow grafting (ABMG). In this patient, melphalan pharmacokinetics was different from that of patients without important renal dysfunction for the area under the concentration curve (1,324 mg.l-1.min). However, with a melphalan elimination half-life of 80 min, ABMG could be performed, as usually, 24 h after melphalan administration. Plasma alpha-fetoprotein (AFP) concentrations showed that chemotherapy was efficient. Furthermore, we observed a modification of etoposide kinetics due to melphalan.
