Résumé
Many guidelines and safety measures led to a decrease in exposure to antineoplastic agents. Since healthcare workers are often exposed to lower concentrations than patients, a sensitive method is needed to quantify occupational exposure. The aim of this study was to develop and validate a sensitive method for simultaneous detection and quantification of cyclophosphamide, ifosfamide and paclitaxel in urine by use of UPLC-MS/MS with a UniSpray ionisation source. Compounds were extracted from urine using Novum simplified liquid extraction cartridges, separated on a C18 column, ionised by a UniSpray ionisation source and detected with MS/MS. In the second part of the study, a field study was performed to assess occupational exposure to antineoplastic agents. Eighty-three samples from healthcare workers were analysed and resulted in seventeen samples containing quantifiable concentrations of at least one compound. In conclusion, a sensitive method for simultaneous detection and quantification of cyclophosphamide (LLOQ 0.05 ng/mL), ifosfamide (LLOQ 0.3 ng/mL) and paclitaxel (LLOQ 0.7 ng/mL) was developed and validated.
