[Cancer and immunosuppression : experimental aspects].

J Maral, I Florentin, C Soubrane

    Bulletin Du Cancer
    |January 1, 1983
    PubMed
    Summary

    Immunosuppression can promote cancer development, influencing both tumor initiation and growth. The complex interplay between the immune system and cancer cells, involving T-cells, macrophages, and NK cells, impacts tumor progression and treatment outcomes.

    Area of Science:

    • Immunology
    • Oncology
    • Carcinogenesis

    Context:

    • The relationship between immune suppression and cancer development is complex and debated.
    • Demonstrating tumor antigens and understanding immune destruction of tumor cells are challenging.
    • Existing research highlights the roles of T-cells, macrophages, and NK cells in immunosurveillance.

    Purpose:

    • To review the current understanding of how immune depression influences cancer development.
    • To explore the mechanisms by which the immune system controls or fails to control tumor growth.
    • To explain the variability in cancer immunotherapy outcomes due to immune complexity.

    Summary:

    • T-cell mediated immunity controls virus-induced tumors, with T-cell depression increasing tumor incidence.
    • Macrophages and NK cells are crucial for controlling chemically induced or spontaneous tumors; their deficiency enhances tumor growth.
    • Established tumors can induce further immune suppression, fostering their own growth through various factors and promoting tumor heterogeneity.

    Impact:

    • Understanding these complex immune-cancer interactions is vital for developing effective cancer prevention and immunotherapy strategies.
    • This review clarifies the multifaceted role of the immune system in cancer, from initiation to progression.
    • The findings underscore the challenges and potential avenues for improving cancer treatment by modulating immune responses.
