入选标准
- •Patients must have a histologically documented primary, recurrent or residual meningioma which is unresectable.
- •Patients must have active meningioma, which is defined to be one of the following:
- •Progressive disease within the past 2 years.
- •Recurrent Disease, as defined by the reappearance of a previously completely resected meningioma, within the past two years.
- •New disease, defined as a diagnosis of meningioma within the previous two years
- •Patients must have measurable or evaluable disease which is documented on CT or MRI scan.
- •Patients should have already received radiotherapy unless radiotherapy is inappropriate due to tumor location(s) or unless radiotherapy, after discussion with the patient's physician, has been refused. If patients have received prior radiotherapy, this treatment must have been completed more than one year prior to study entry with documented progressive disease since completion of radiotherapy.
- •Patients must be 18 years or older, and must have a performance status 0-2 by Southwest Oncology Group criteria.
- •Patients must not have received prior cytotoxic chemotherapy for meningioma.
- •Patients must have serum creatinine, SGOT, and bilirubin ≤ 2 x IULN.
- •Patients requiring simultaneous administration of corticosteroids for cerebral edema must have been receiving a stable dose of corticosteroids for at least 4 weeks prior to study entry.
- •Patients receiving anti-epileptic medications are eligible. However barbiturates should be avoided if possible.
- •Patients with meningiomatosis (diffuse meningeal infiltration resulting in only nonevaluable meningeal thickening) are not eligible. However, patients with multiple measurable or evaluable meningioma tumor masses are eligible.
- •Patients with malignant meningioma are not eligible. Malignant meningioma is defined as meningioma that demonstrates hypercellularity, loss of architecture, nuclear pleomorphism, numerous mitoses, focal necrosis, and brain invasion.
- •Patients who have had additive or ablative modulation of sex hormone or glucocorticoid pathways within the preceding 3 months (not including stable corticosteroid therapy for cerebral edema) are not eligible. Such modulations include but are not limited to birth control pills, bilateral oophorectomy or orchiectomy, progestational inserts, oral or vaginal exogenous estrogens, androgens or antiandrogens, progestational agonists, tamoxifen, aminoglutethimide, o,p-DDD, ACTH, glucocorticoids not for cerebral edema, and leuprolides (or other LH-RH inhibitors). Patients must not have received prior mifepristone therapy for meningioma.
- •Patients must not have serious intercurrent medical illness; that is, any illness that in the opinion of the investigator would prevent following the study regimen.
- •Patients with clinical adrenal insufficiency requiring exogenous corticosteroid replacement are not eligible.
- •Patients with a known allergy to mifepristone are not eligible.
- •Patients with base of brain, cavernous sinus or optic nerve meningiomas or with visual symptoms must have a formal visual field examination.
- •Pregnant or lactating women may not participate. Pre-menopausal women and men of reproductive potential may not participate unless they have agreed to use an effective local contraceptive method (such as a condom, diaphragm, or IUD) or abstinence during and for 3 months after study therapy.
- •Patients with other prior or concurrent malignancy within the preceding 5 years, except surgically treated squamous or basal cell skin cancer or cervical cancer in situ, are not eligible.
