Ferritin levels and circulating immune complexes in patients with solid tumors

A Celada, M Barnet, M T Aguado

    Bulletin Du Cancer
    |January 1, 1982
    PubMed
    Summary

    Levels of ferritin and circulating immune complexes (IC) are elevated in patients with solid tumors and metastasis. However, these two markers are not correlated, and ferritin is not a significant component of these immune complexes.

    Area of Science:

    • Oncology
    • Immunology
    • Biochemistry

    Background:

    • Elevated ferritin levels are observed in various cancers.
    • Circulating immune complexes (IC) are implicated in disease pathogenesis.
    • The relationship between ferritin, IC, and solid tumors requires further elucidation.

    Purpose of the Study:

    • To investigate the levels of ferritin and circulating immune complexes (IC) in patients with solid tumors and metastasis.
    • To determine the correlation between ferritin and IC levels in this patient cohort.
    • To assess the contribution of ferritin to immune complexes.

    Main Methods:

    • Quantification of serum ferritin and circulating immune complexes (IC) in 53 patients with solid tumors and metastasis.
    • Utilized C1q binding assay and conglutinin binding assay for IC measurement.

  • Assessed ferritin levels, including correction for hepatic damage using aspartic transaminase values.

    • Main Results:

    • Circulating IC levels were significantly increased in patients compared to controls (p < 0.001).
    • Ferritin levels were significantly elevated in both male and female patients (p < 0.001), even after adjusting for hepatic damage.
    • Ferritin constituted less than 2% of total serum ferritin in immune complexes, indicating it's not a major component.

    Conclusions:

    • Both ferritin and circulating IC are elevated in patients with solid tumors and metastasis.
    • There is no significant correlation between ferritin levels and circulating IC levels in these patients.
    • Ferritin is not a primary component of the measured immune complexes in this study.
