Luteinizing hormone-releasing hormone agonists and meningioma: A treatment dilemma

The relative contraindication of hormonal therapy for patients with prostate cancer and a history of meningioma has not been widely emphasized. Using immunohistochemistry to determine the presence of hormone receptors in meningioma specimens proved potentially valuable in 2 patients with biochemical recurrence after prostatectomy who were being considered for androgen deprivation therapy. These cases also highlight the need for caution against assuming that skull-based intracranial growths in patients receiving hormonal therapy for prostate cancer are metastatic lesions rather than hormonally induced primary tumors.
