The interferon system in patients with malignant disease.

T Hahn, S Levin

    Journal of Interferon Research
    |January 1, 1982
    PubMed
    Summary

    Cancer patients show elevated interferon (IFN) levels but their cells poorly respond to IFN. This deficient cellular response, not production ability, may drive cancer progression, suggesting new therapeutic targets.

    Area of Science:

    • Immunology
    • Oncology
    • Virology

    Background:

    • The interferon (IFN) system is crucial for immune response.
    • IFN therapy shows promise in cancer treatment.
    • The role of the endogenous IFN system in malignancy is understudied.

    Purpose of the Study:

    • To investigate the components of the endogenous IFN system in cancer patients.
    • To assess IFN production and cellular response in malignancy.

    Main Methods:

    • Analysis of blood IFN levels in cancer patients.
    • Evaluation of peripheral blood mononuclear cell response to IFN.
    • Measurement of in vitro IFN production by cancer cells.

    Main Results:

    • Elevated blood IFN levels were observed in a high incidence of cancer patients.
    • Peripheral blood mononuclear cells from cancer patients showed a deficient response to both endogenous and exogenous IFN.
    • Increased spontaneous, uninduced IFN production was noted in vitro from cancer cells.

    Conclusions:

    • Cancer patients possess the capacity to produce IFN.
    • A deficient cellular response to IFN, rather than impaired production, may contribute to cancer development and progression.
    • Increased spontaneous IFN production suggests potential intracellular inducers in cancer cells.
