Liver transplantation for metastasized extragastrointestinal stromal tumor: a case report and an overview of literature.
A 63-year-old woman underwent living donor liver transplantation for hepatic metastases of an extragastrointestinal stromal tumor (EGIST) originating from the rectovaginal space. Due to a multifocal extrahepatic tumor recurrence, treatment with imatinib mesylate was started after extensive pharmacokinetic studies to rule out possible interactions with immunosuppressives. We performed several re- resections for EGIST recurrence thereafter. At the last follow-up, 17 years after primary tumor resection and 10 years after living donor liver transplantation, the patient is symptom-free under immunosuppressive and imatinib mesylate treatments with a 2-cm stable recurrent pararectal EGIST. To our knowledge, this is the only report published on a patient who underwent transplantation for hepatic EGIST metastases with a posttransplantation follow-up of 10 years and the first report on living donor liver transplantation for metastasized EGIST. This is the first description of pharmacokinetics of imatinib and its main active metabolite CGP74588 in a liver transplant recipient.

Pharmacokinetics of imatinib mesylate in end stage renal disease. A case study.
To evaluate the pharmacokinetics of imatinib mesylate (Glivec) and its main metabolite (CGP74588) in a patient with end stage renal disease on hemodialysis and compare it with published data from subjects with normal renal function.. Serial blood samples were collected over a 2-weeks period in a patient who was receiving daily 400 mg oral imatinib mesylate for the treatment of a gastrointestinal stromal tumor metastatic to the liver while on hemodialysis. Plasma levels of imatinib and CGP74588 were determined by a liquid chromatography-tandem mass spectrometry assay.. The pharmacokinetic values for imatinib and CGP74588, respectively, were: maximum concentration (3,340 and 781 ng/ml), time to maximum concentration (2 h), half-life (18.2 and 34.0 h), area under the curve (53.9 and 14.8 microg.h/ml), and trough concentration (1,540 and 508 ng/ml) for at least 24 h. All obtained values fell within the range of values of imatinib and its metabolite obtained in patients with normal renal function. Dialysis courses were not found to intervene with plasma kinetics of the study drug.. Our results indicate that the pharmacokinetics of imatinib and its metabolite CGP74588 do not change in patients with end stage renal disease on hemodialysis. Thus, the standard dose of imatinib can be safely administered to patients on hemodialysis, and probably with renal failure, at any stage.
