Serum selenium and reticuloendothelial tumors.

W L Broghamer, K P McConnell, M Grimaldi

    Cancer
    |April 1, 1978
    PubMed
    Summary

    Serum selenium levels were measured in patients with reticuloendothelial neoplasms. Early cancer therapy, especially within six weeks, was linked to increased selenium levels in the blood.

    Area of Science:

    • Oncology
    • Trace Element Analysis
    • Biochemistry

    Background:

    • Reticuloendothelial neoplasms encompass a range of cancers affecting the immune system.
    • Selenium is a vital trace element with antioxidant and immune-modulating properties.
    • Variations in serum selenium levels may be associated with neoplastic diseases and their treatment.

    Purpose of the Study:

    • To investigate the relationship between serum selenium concentrations and reticuloendothelial neoplasms.
    • To explore potential correlations between selenium levels and various clinical parameters in these patients.
    • To assess the impact of early-stage therapy on serum selenium levels.

    Main Methods:

    • Serum selenium levels were quantified using neutron activation analysis.
    • The study included 59 patients diagnosed with various reticuloendothelial neoplasms.
    • Correlations were sought between serum selenium concentrations and clinical data.

    Main Results:

    • Serum selenium levels exhibited significant variability among the patient cohort.
    • A notable finding was the elevation of serum selenium levels following the initiation of therapy.
    • This elevation was particularly pronounced in patients undergoing treatment for less than six weeks.

    Conclusions:

    • Serum selenium levels in patients with reticuloendothelial neoplasms are influenced by therapeutic interventions.
    • Early cancer treatment appears to be a significant factor in increasing blood selenium concentrations.
    • Further research is warranted to understand the clinical implications of these selenium level changes in cancer patients.
