Note: Patients who received adjuvant or neo-adjuvant chemotherapy more than 12 months
prior will be eligible?

4. Has measurable disease, defined as at least one lesion that can be accurately
measured in at least one dimension (longest diameter to be recorded) as > 20 mm with
conventional techniques or as > 10 mm with spiral computed tomography (CT) scan?

EXCLUSION CRITERIA:

Response should be NO

1. Has any of the following within 6 months prior to study enrollment: myocardial

that may cause undue risk for the subject's safety, inhibit protocol participation,
or interference with interpretation of study results, and in the judgment of the
investigator would make the subject inappropriate for entry into this study?
