Hypophysectomy for stage IV breast cancer.

O H Pearson, J S Brodkey, A Manni

    The Surgical Clinics of North America

    Summary

    Transnasal, transsphenoidal hypophysectomy offers a low-risk treatment for advanced breast cancer. It is recommended after antiestrogen therapy, especially for patients who initially respond or fail to benefit from antiestrogens.

    Area of Science:

    • Oncology
    • Neurosurgery
    • Endocrinology

    Background:

    • Transnasal, transsphenoidal microsurgical hypophysectomy is a viable treatment for Stage IV breast cancer.
    • Complete hypophysectomy is crucial for therapeutic success, though remissions can occur with incomplete procedures.

    Purpose of the Study:

    • To evaluate the efficacy of hypophysectomy in advanced breast cancer patients.
    • To determine the role of hypophysectomy in conjunction with antiestrogen therapy.
    • To explore patient selection criteria for hypophysectomy.

    Main Methods:

    • Transnasal, transsphenoidal microsurgical hypophysectomy.
    • Antiestrogen therapy.
    • Estrogen and prolactin receptor analysis in tumor tissue.

    Main Results:

    • Hypophysectomy can be performed with minimal morbidity and mortality in selected patients.
    • Antiestrogen therapy shows outstanding results, and hypophysectomy can induce further improvement.
    • Estrogen receptor status is useful for patient selection; prolactin receptors are under investigation.

    Conclusions:

    • Hypophysectomy is a definitive treatment for advanced breast cancer, not a last resort.
    • Antiestrogen therapy should be considered the initial treatment for eligible patients.
    • Patient selection using tumor receptor status is key for successful hypophysectomy and antiestrogen therapy.
