Summary
Brief summary (as posted)
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Some patients may develop a resistance to chemotherapy drugs. PURPOSE: Phase II trial to determine the reliability of a test for measuring drug resistance to paclitaxel in patients with metastatic breast cancer.
