This study quantified copper and zinc levels in breast cancer patients' wound fluid and blood plasma. Findings reveal distinct trace element species, offering insights into their role in cancer progression.

Area of Science:

  • Analytical Chemistry
  • Biochemistry
  • Oncology

Background:

  • Trace elements like copper and zinc play crucial roles in biological processes.
  • Understanding their speciation in disease states, such as breast cancer, is vital.
  • Wound fluid offers a unique matrix for studying local physiological changes.

Purpose of the Study:

  • To quantify copper and zinc concentrations in breast cancer patient wound fluid and blood plasma.
  • To identify the specific chemical species of copper and zinc present in these samples.
  • To compare trace element levels between wound fluid, plasma, and reference values.

Main Methods:

  • Potentiometric Stripping Analysis (PSA) was employed for trace element quantification.
  • Computer-aided chemical speciation modeling (using JESS) identified individual metal species.

  • Analysis included wound fluid, pre-operative blood plasma, and reference values.

    • Main Results:

    • Quantified total concentrations of copper and zinc in wound fluid and plasma.
    • Identified predominant copper and zinc species in wound fluid using a JESS model.
    • Investigated the influence of pH and component concentrations on species predominance.

    Conclusions:

    • The study provides detailed speciation of copper and zinc in breast cancer patient samples.
    • The findings highlight the potential clinical significance of trace element profiles in wound fluid.
    • Further research is recommended to explore the implications of these trace element species.
