Summary
RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of tumor
cells, either by killing the cells or by stopping them from dividing. Measuring blood levels
of tumor cells may help in learning how well chemotherapy works to kill metastatic breast
cancer cells and allow doctors to plan better treatment. When blood levels of tumor cells are
high while receiving chemotherapy, it is not yet known whether it is more effective to change
chemotherapy regimens at that time or wait until disease progression.
PURPOSE: This randomized phase III trial is studying treatment decision making based on blood
levels of tumor cells in women with metastatic breast cancer receiving chemotherapy.
Phase:
