Circulating immune complexes in patients with breast cancer
British Medical Journal
|July 23, 1977
Summary
Circulating immune complex levels were elevated in breast cancer patients before surgery. Post-mastectomy, normal levels indicated good prognosis, while high levels suggested disease recurrence or poorer outcomes.
Area of Science:
- Oncology
- Immunology
Background:
- Circulating immune complexes (CICs) are implicated in various diseases.
- Their role in breast cancer prognosis requires further elucidation.
Purpose of the Study:
- To investigate the correlation between plasma CIC levels and breast cancer prognosis.
- To assess the potential of CIC measurement as a prognostic marker.
Main Methods:
- Retrospective analysis of breast cancer patients.
- Measurement of CIC levels using radioimmunoprecipitation with 125I-Clq.
Main Results:
- Pre-operative CIC levels were significantly higher in patients than controls.
- Post-mastectomy, patients with good prognosis showed near-normal CIC levels.
- Elevated CIC levels post-mastectomy correlated with detectable dissemination or mortality within 22 months.
Conclusions:
- Plasma CIC levels may serve as a prognostic indicator in breast cancer.
- Further research is needed to confirm the tumor-specific nature of CICs and their utility in monitoring disease course.
