- Have no evidence of new or enlarging brain metastases, and
- Are not using steroids =< 14 days prior to registration
- Known leptomeningeal disease
- Co-morbid systemic illnesses or other severe concurrent disease which, in the judgment
of the investigator, would make the patient inappropriate for entry into this study or
interfere significantly with the proper assessment of safety and toxicity of the
prescribed regimens
- Known active human immunodeficiency virus (HIV) infection (defined as patients who are
not on anti-retroviral treatment and have detectable viral load and CD4+ < 500/ml).
NOTE: HIV-positive patients who are well controlled on anti-retroviral therapy are
