Serum folate binding capacity in patients with solid tumors

R Corrocher, M L Pachor, L M Bambara

    Tumori
    |March 1, 1981
    PubMed
    Summary

    Total folate binding capacity (TFBC) increased significantly in most solid tumor patients, including lung, gastrointestinal, and breast cancers. Unsaturated folate binding capacity (UFBC) also rose in lung and GI cancer patients, indicating altered folate metabolism in cancer.

    Area of Science:

    • Biochemistry
    • Oncology
    • Clinical Chemistry

    Background:

    • Folate metabolism plays a crucial role in cell proliferation and is often altered in cancer.
    • Total folate binding capacity (TFBC) and unsaturated folate binding capacity (UFBC) are biochemical markers that reflect folate levels and binding proteins in circulation.

    Purpose of the Study:

    • To investigate alterations in TFBC and UFBC in patients with various solid tumors.
    • To explore potential correlations between TFBC, UFBC, and specific cancer types, including breast cancer subtypes.

    Main Methods:

    • Measurement of TFBC and UFBC in 44 healthy volunteers and 77 cancer patients.
    • Patient cohorts included lung cancer, gastrointestinal tract cancer, and breast cancer.
    • Analysis of TFBC and UFBC levels across different cancer groups and in relation to breast cancer characteristics.

    Main Results:

    • TFBC was significantly elevated in most solid tumor groups, except for stomach cancer.
    • UFBC showed a statistically significant increase in patients with lung cancer and gastrointestinal tract cancer.
    • No correlation was found between TFBC and hormone receptors in breast cancer, but TFBC increased with the presence of metastases.

    Conclusions:

    • Elevated TFBC is a common finding in various solid tumors, suggesting widespread metabolic changes.
    • Increased UFBC in lung and GI cancers indicates specific alterations in folate transport or binding.
    • TFBC may serve as a potential biomarker for cancer progression, particularly in breast cancer with metastases.
