more years prior to study entry and is deemed by her physician to be at low risk for
recurrence. Patients with the following cancers are eligible if diagnosed and

surgery) during the course of study therapy and for at least 3 months following the
last dose of pazopanib.
- Pregnancy or lactation at the time of study entry.
- Other nonmalignant systemic disease that would preclude the patient from receiving
study treatment or would prevent required follow-up.
