    Notes: Abstract The ability of human peripheral blood lymphocytes to convert the androgenic steroid metabolite androstenedione diminishes in women over 45 years old or during menopause. In patients with breast cancer in menopause the ability of lymphocytes to convert androstenedione is enhanced compared with the control. The intensity of conversion in circulating lymphocytes correlates with the blood concentration of sex steroids.

    Notes: Abstract Lymphocytes infiltrating tumor tissue are capable of androstenedione conversion, which was assessed from3H2O release from tritium-labeled androgen precursor of estrogens 1β-androstenedione. This capacity is higher in menopausal patients than in patients of reproductive age. A tendency to a positive correlation between the intensity of androstenedione conversion in lymphocytes and aromatase activity in tumor tissue is revealed. No relationship between androstenedione conversion in lymphocytes and contamination of the isolated cell suspension with tumor cells is detected.
