Area of Science:

  • Pharmacology
  • Materials Science
  • Clinical Chemistry

Background:

  • Diethylhexylphthalate (DEHP) is a common plasticizer in polyvinyl chloride (PVC) plastics.
  • DEHP is known to leach from PVC medical devices, including those used for drug administration.

Purpose of the Study:

  • To quantify the leaching of DEHP from PVC infusion bags and transfer sets during paclitaxel administration.
  • To assess patient exposure to DEHP in peritoneal fluid and urine during intraperitoneal chemotherapy.

Main Methods:

  • In vitro experiments using high-performance liquid chromatography to measure DEHP leaching from PVC containers with paclitaxel solutions.
  • Analysis of DEHP levels in peritoneal fluid and urine from a patient receiving intraperitoneal paclitaxel.

Main Results:

  • Significant amounts of DEHP (approx. 26 mg/24h) leached from 1L PVC bags containing paclitaxel in dextrose solution.
  • DEHP leaching was also observed from transfer tubing, with accumulation over time.
  • In a patient, DEHP was detected in peritoneal fluid (approx. 3% recovered) and urine (approx. 27% excreted) within 24 hours.

Conclusions:

  • Paclitaxel administration from PVC containers results in DEHP leaching and patient exposure.
  • Precautionary measures are essential to minimize DEHP transfer during intraperitoneal paclitaxel therapy.
  • Alternatives to DEHP-containing plastics or specific administration protocols are recommended to reduce patient risk.
