    Area of Science:

    • Oncology
    • Pharmacology
    • Biotechnology

    Background:

    • Existing animal models for cancer drug testing show significant differences from human malignancies.
    • There is a need for improved in vitro and in vivo systems to accurately predict antitumor drug efficacy in humans.
    • Individualized tumor treatment requires a deeper understanding of drug action at the cellular level.

    Purpose of the Study:

    • To highlight the necessity of advanced test systems for selecting effective antitumor drugs.
    • To emphasize the potential of studying drug action determinants in normal and malignant cells.
    • To advocate for the development of cell separation techniques for analyzing human tumor samples.

    Main Methods:

    • Utilizing T cell-deprived or nude mice to host human tumor xenografts.

  • Developing and refining cell separation techniques for isolating malignant cells.
  • Employing morphological, biochemical, and genetical markers for identifying human malignant cells.

    • Main Results:

    • Human malignant cells can be successfully analyzed for drug sensitivity in leukemias and metastatic fluids.
    • The use of human tumor xenografts in specialized mice allows for in vivo drug testing.
    • Progress in cell separation and characterization is crucial for advancing drug sensitivity studies.

    Conclusions:

    • Advanced test systems, including human tumor xenografts, are essential for effective antitumor drug development.
    • Studying drug sensitivity in malignant cells, particularly with improved cell analysis techniques, can lead to more rational and individualized cancer therapies.
    • The approach holds promise for improving treatment strategies for solid tumors, mirroring successes in leukemia and metastatic cancers.
