Polyamines as biological markers in malignant lymphomas.

A Thyss, G Milano, C Caldani

    European Journal of Cancer & Clinical Oncology
    |July 1, 1982
    PubMed
    Summary

    Urinary polyamines like putrescine (PU) and spermidine (SPD) show promise in monitoring non-Hodgkin lymphoma (NHL) progression and treatment response. Levels correlate with NHL stage and chemotherapy effectiveness, unlike in Hodgkin

    Area of Science:

    • Biochemistry
    • Oncology
    • Urology

    Background:

    • Polyamines, including putrescine (PU) and spermidine (SPD), are crucial for cell growth and proliferation.
    • Altered polyamine metabolism is implicated in various cancers, including lymphomas.
    • Urinary polyamine levels may serve as non-invasive biomarkers for cancer detection and monitoring.

    Purpose of the Study:

    • To investigate the potential of urinary polyamines (putrescine and spermidine) as biomarkers for non-Hodgkin lymphoma (NHL) and Hodgkin's disease (HD).
    • To assess the correlation between polyamine levels and disease severity, type, and treatment response in lymphoma patients.
    • To evaluate the utility of serial polyamine measurements in tracking disease activity and chemotherapy efficacy.

    Main Methods:

    • Quantitative analysis of urinary putrescine (PU) and spermidine (SPD) levels.

  • Serial monthly measurements over an average follow-up of 12.5 months in 67 lymphoma patients (48 NHL, 18 HD).
  • Comparison of polyamine levels with disease stage, histological subtype, and chemotherapy response.

    • Main Results:

    • Significant association between urinary polyamine levels and NHL stage severity.
    • Distinct polyamine value distributions observed between nodular and diffuse forms of NHL.
    • Urinary PU levels reflected disease activity in NHL patients over time.
    • No significant correlations found between polyamine levels and disease parameters in HD patients.
    • Urinary polyamine levels differentiated complete responders from partial/non-responders to chemotherapy in NHL.

    Conclusions:

    • Urinary polyamines (PU and SPD) are potential biomarkers for monitoring NHL progression and treatment response.
    • Serial monitoring of urinary PU may indicate disease activity in NHL.
    • Urinary polyamines do not appear to be reliable biomarkers for HD.
    • Further research is warranted to validate these findings and explore clinical applications.
