    Interferon therapy shows promise for cancer treatment by inhibiting tumor growth and enhancing immune response. Further research is needed to understand patient response variability and optimize treatment strategies for better outcomes.

    Area of Science:

    • Immunology
    • Oncology
    • Biotechnology

    Background:

    • Interferons (IFNs) are known for their anti-tumor effects in various cancers.
    • Despite recombinant DNA technology advancements providing ample human interferons (leukocyte alpha-interferon, fibroblast beta-interferon, immune gamma-interferon), their clinical application in cancer therapy remains unclear.
    • Understanding interferon mechanisms and inactivity is crucial for effective cancer treatment.

    Purpose of the Study:

    • To elucidate the mechanisms by which interferons exert anti-tumor effects.
    • To identify reasons for interferon therapy's limited efficacy in certain cancer cases.
    • To evaluate the implications of interferon's diverse actions on cancer treatment strategies.

    Main Methods:

    • Assessing interferon's potential roles: antiviral action, growth inhibition, cell differentiation, immune modulation, and effects on host immune systems (natural killer cells, cytotoxic proteins).

  • Evaluating alpha- and beta-interferons for growth inhibition and differentiation effects.
  • Assessing gamma-interferon's role in immune recognition and rejection of tumor cells.
  • Investigating synergistic effects of combined alpha- and gamma-interferon therapy in vitro.
  • Measuring oncogene mRNA inhibition, G0/G1 arrest, and HLA antigen increases to determine tumor cell sensitivity to different interferons.
  • Considering treatment aims (antiviral, tumor regression, metastasis prevention, growth decrease, differentiation increase) for therapy selection.

    • Main Results:

    • Alpha- and beta-interferons may inhibit tumor growth and promote differentiation.
    • Gamma-interferon appears more effective in enhancing immune recognition and rejection of tumor cells.
    • Combined alpha- and gamma-interferon may offer synergistic benefits in vivo.
    • Tumor cell sensitivity to interferons can be assessed via oncogene mRNA, cell cycle arrest, and HLA antigen expression.
    • A significant challenge remains in understanding the low objective response rate in patients undergoing interferon therapy.

    Conclusions:

    • Interferon therapy holds potential for cancer treatment through multiple mechanisms.
    • Combination therapy, particularly with alpha- and gamma-interferons, may yield optimal results.
    • Personalized assessment of tumor cell sensitivity and clear treatment goals are essential for effective interferon application in oncology.
