About

The purpose of this study is to study patients presenting with stage IV breast cancer. Stage IV means that the breast cancer has spread to another part of the body outside the breast. This study is important because in different parts of the country some patients are being offered surgical treatment for the breast tumor and some are not. The doctors do not know if surgery for the breast tumor is helpful in patients with stage IV breast cancer. The doctors will collect information about the patient and their treatment to learn more about how patients and doctors make treatment decisions. The doctor will also collect blood samples and tissue samples for laboratory studies to learn more about tumors that have spread to other parts of the body.

Trial design

100 participants in 2 patient groups

Known or suspected Stage IV disease & an intact primary

Description:

Pt will be asked to undergo a research core needle biopsy of the primary tumor. If pts are not agreeable to a research biopsy then the original diagnostic biopsy material will be requested. They will also undergo a diagnostic biopsy of a metastatic site, if not already performed, and a blood draw as appropriate for correlative science studies. Additionally, patients will complete a general medical questions form at the time of enrollment.

Unsuspected metastatic disease W/I 3 months of primary b

Description:

A blood sample will be collected and patients will complete a general medical questions form at the time of enrollment. Paraffin tissue from the prior surgical procedure will be obtained as Tissue sample. Paraffin tissue from the diagnostic biopsy of a metastatic site will also be obtained. In the event that fresh frozen tissue is available for either site this will also be requested.
