title: [Measurement of busulfan concentration in plasma and spinal fluid from transplant patients pretreated with busulfan and cyclophosphamide].
abstract: Busulfan (BU) concentrations in the blood and spinal fluid of 7 patients pretreated with BU for bone marrow transplantation (BMT) were measured using gas chromatography. The data from these periodically obtained samples were used to study the relationship between the BU concentration and complications (e.g. vomiting), indicating that vomiting leads to a lower maximum BU level. The trough level of BU concentration at 6 hours after administration was stable at around 500 ng/ml, not showing little effect of vomiting. The BU concentrations in the spinal fluid were virtually the same as those in plasma collected at the same time and the spinal fluid/plasma ratio of the BU concentration averaged 1.06. No veno-occlusive disease (VOD) was noted. Failure of engraftment occurred in one case of myelofibrosis, however, as the plasma BU concentration in this case was not lower than the others, the graft failure was not considered to be due to the preconditioning regimen including BU.
