A new UPLC-MS/MS method accurately quantifies occupational exposure to cyclophosphamide, ifosfamide, and paclitaxel in healthcare workers. This sensitive technique helps monitor antineoplastic agent exposure in the workplace.
Area of Science:
- Analytical Chemistry
- Occupational Health
Background:
- Decreased antineoplastic agent exposure due to safety measures.
- Need for sensitive methods to quantify low-level occupational exposure in healthcare workers.
Purpose of the Study:
- Develop and validate a sensitive UPLC-MS/MS method for simultaneous detection of cyclophosphamide, ifosfamide, and paclitaxel.
- Assess occupational exposure to these antineoplastic agents in healthcare workers.
Main Methods:
- Urine sample extraction using Novum cartridges.
- Separation on a C18 column.
- Ionization via UniSpray and detection with MS/MS.
Main Results:
- Quantifiable concentrations of at least one antineoplastic agent found in 17 out of 83 healthcare worker samples.
- Validated method with low limit of quantification (LLOQ) for cyclophosphamide (0.05 ng/mL), ifosfamide (0.3 ng/mL), and paclitaxel (0.7 ng/mL).
Conclusions:
- A sensitive and validated UPLC-MS/MS method for simultaneous quantification of key antineoplastic agents in urine was successfully developed.
- The method is suitable for assessing occupational exposure in healthcare settings.
