    Summary

    Thyroid cancer inhibits thyroid function, while adenomas increase it, altering thyrotropin levels. These hormonal changes differ between sexes and worsen with age, particularly in advanced thyroid cancer.

    Area of Science:

    • Endocrinology
    • Oncology
    • Thyroid Gland Physiology

    Background:

    • Thyroid gland disorders, including adenoma and cancer, significantly impact hormone regulation.
    • Understanding the specific hormonal profiles in these conditions is crucial for diagnosis and management.

    Purpose of the Study:

    • To investigate and compare the levels of thyroid hormones and thyrotropin in patients with thyroid adenoma versus thyroid cancer.
    • To analyze potential differences in hormonal disturbances based on sex, age, and disease dissemination.

    Main Methods:

    • Radioimmunological assays were used to measure thyroid hormone and thyrotropin levels.
    • Data were collected from 58 patients with thyroid adenoma and 86 patients with thyroid cancer.

    Main Results:

    • Thyroid cancer was associated with inhibited thyroid secretory function and elevated thyrotropin levels.
    • Thyroid adenoma showed increased secretory function and lowered thyrotropin levels.
    • Hormonal disturbances were more pronounced in males and in disseminated cancer patients aged 46-55, suggesting age-related decline in thyroid function.

    Conclusions:

    • Distinct hormonal profiles characterize thyroid adenoma and cancer, impacting thyroid hormone and thyrotropin regulation.
    • Age and sex influence the severity of hormonal imbalances in thyroid cancer patients.
    • Findings suggest a natural decline in thyroid function with aging, exacerbated by advanced thyroid cancer.
