PRIMARY OBJECTIVES:
I. To evaluate the safety and tolerability of low-dose oral minoxidil in patients with breast cancer and EIA.
II. To obtain preliminary data to support whether low-dose oral minoxidil is a reasonable alternative to topical minoxidil in patients with EIA.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM I: Patients apply minoxidil foam topically to affected areas of the scalp once daily (QD) for up to 12 months in the absence of disease progression or unacceptable toxicity.
ARM II: Patients receive minoxidil orally (PO) QD for up to 12 months in the absence of disease progression or unacceptable toxicity.
