[Testosterone and prostatic cancer (author's transl)]

R Morfin, J F Charles, L Tiengou

    Journal D'Urologie Et De Nephrologie
    |July 1, 1977
    PubMed
    Summary

    Prostate cancer cells lose differentiation as testosterone metabolism changes. The testosterone metabolites ratio can predict this loss and guide antiandrogen therapy decisions.

    Area of Science:

    • Urology
    • Endocrinology
    • Oncology

    Context:

    • Prostate gland epithelial cells are hormone-dependent.
    • Neoplastic transformation leads to loss of differentiation.
    • Testosterone metabolism is altered in prostate cancer.

    Purpose:

    • To investigate the relationship between testosterone metabolism and prostate cancer differentiation.
    • To identify a biomarker for predicting loss of differentiation.
    • To inform antiandrogenic therapy strategies.

    Summary:

    • Loss of histologic and cytologic differentiation in prostate cancer correlates with altered testosterone metabolism.
    • The ratio of testosterone metabolites (17 beta-hydroxy/17-oxometabolites) decreases with reduced differentiation and increased androgen independence.
    • This ratio serves as an indicator of disease progression.

    Impact:

    • Provides a potential biomarker for assessing prostate cancer progression.
    • Suggests a method for patient stratification before antiandrogenic therapy.
    • Aids in understanding the role of testosterone metabolism in prostate cancer development.
