    Area of Science:

    • Immunology
    • Oncology
    • Biochemistry

    Background:

    • Peripheral blood lymphocytes play a role in immune responses.
    • Cancer diagnosis relies on various biomarkers and tests.
    • The Poly-l-lysine 3400 (PAL) test is a novel assay for lymphocyte agglutination.

    Purpose of the Study:

    • To investigate the diagnostic potential of the Poly-l-lysine 3400 (PAL) test.
    • To determine the association between PAL-test reactivity and malignant disorders.
    • To evaluate the PAL-test's efficacy in distinguishing cancer patients from healthy individuals and those with non-malignant conditions.

    Main Methods:

    • Investigated peripheral blood lymphocytes from 300 subjects (cancer patients, non-malignant disorder patients, healthy controls).
    • Assessed lymphocyte agglutination using Poly-l-lysine 3400 (PAL-test).

    Related Experiment Videos

  • Correlated PAL-test results with clinical diagnoses.

    • Main Results:

    • A high level of association was confirmed between clinically evident cancer and a positive PAL-test reaction.
    • Positive reactions were observed in 72 of 90 (80%) patients with malignant diseases.
    • Lymphocytes from 33 of 140 patients with non-malignant processes also showed positive reactions, while all healthy controls were negative.
    • The overall positive evidence of the PAL-test amounted to over 80%.

    Conclusions:

    • The PAL-test demonstrates significant potential as a biomarker for detecting malignant diseases.
    • The test shows high sensitivity in identifying cancer patients.
    • Further research into the mechanisms underlying the PAL-test's reactivity is warranted.
