Abstract

A rapid and sensitive LC–MS/MS method for therapeutic drug monitoring oral vinorelbine (VRL) metronomic anticancer chemotherapy has been developed and validated. Analysis of VRL and its main active metabolite 4-O-deacetylvinorelbine (M1) was performed in whole blood matrix. Both analytes were extracted by protein precipitation and separated on an Onyx monolith C18, 50 × 2 mm column then quantified by positive electrospray ionization and multiple reaction monitoring mode. The LLOQ was 0.05 ng/mL for both VRL and M1. Linearity was up to 25ng/mL with R2 ≥ 0.994. The intra- and inter-assay precisions were ≤ 11.6 and ≤ 10.4% while the ranges of accuracy were [−8.7%; 10.3%] and [−10.0; 7.4%] for VRL and M1, respectively. The clinical suitability of the method has been proved by the determination of the CTrough blood concentrations of VRL and M1 in 64 nonsmall cell lung cancer elderly patients. The analytical performance of the assay was suitable for pharmacokinetic monitoring of VRL and M1, allowing the personalization of the VRL metronomic treatments.
