Phase II Study of Tailored-Dose Docetaxel in Metastatic Breast Cancer

You will then receive your first dose of docetaxel chemotherapy. It is put through your IV over 1-2 hours. you will receive docetaxel every 3 weeks in the Cancer Center Infusion area.

you will have an erythromycin breath test, which is an experimental test which is used to estimate the amount of enzyme produced by your liver which can metabolize the chemotherapy, docetaxel. For this test, you go to the GCRC where you will receive an injection of erythromycin (an antibiotic) which is labeled with a very small amount of radioactive substance. 20 minutes later you will blow air from your mouth into a blue solution until it clears. Your doctors will calculate the dose of docetaxel to be given to you based on this blood test, on your body's albumin level (a protein determined on the blood test), and on your height and weight.
