Overview
Brief Summary
This is a multicenter, prospective observational cohort study (OCS) designed to follow patients with locally recurrent or metastatic breast cancer in the United States. Two cohorts will be included:
- Patients with human epidermal growth factor receptor 2-negative (HER2-negative) disease receiving their first cytotoxic chemotherapy and/or targeted therapy (approximately 825 patients)
- Patients with hormone receptor-positive (HR-positive) disease receiving their first hormonal therapy for advanced disease (approximately 425 patients)
Patients who have received any chemotherapy for advanced disease more than 8 weeks prior to enrollment to this OCS will not be eligible. A total of approximately 1,250 patients will be enrolled. Approximately 150 study sites will be activated in order to achieve complete enrollment by December 2010.

Outcomes
Primary Outcomes
Progression Free Survival
Time Frame: Approximately 4.5 years
Progression free survival was defined as the time from enrollment to progression or death of any cause, whichever came first. The disease response status was assessed by the investigator according to the method of his or her choice. The choices included computed tomography (CT) scan, magnetic resonance imaging (MRI), bone scan, X-ray, Positron emission tomography (PET) or CT PET, physical exam, laboratory exam, and other method.
Secondary Outcomes
- Number of Participants With Any Adverse Events, Any Serious Adverse Events, Any AEs Leading to Early Treatment Discontinuation, and Adverse Events Leading to Hospitalization or Death(Approximately 4.5 years)
- Overall Survival(Approximately 4.5 years)
- Number of Participants With Tumor Response(Approximately 4.5 years)
- Number of Hormone Receptor-positive Participants Who Initiated Cytotoxic Chemotherapy Following Discontinuation(Approximately 4.5 years)
- Number of Participants With Arterial Thromboembolic Events, Venous Thromboembolic Events, Left Ventricular Systolic Dysfunction, and Peripheral Neuropathy(Approximately 4.5 years)
