What we are studying
This is an observational study, not a treatment study. The major goal of this study is to see if physicians can predict how women will tolerate and complete chemotherapy as prescribed, using simple assessments of their ability to do activities of daily living. Another goal of the study is to look at how chemotherapy works in older women with cancer, and for this reason you will be asked to allow some research blood to be drawn in order to measure the amount of chemotherapy drug(s) in your blood.
