 The chemotherapy, some of the other drugs in this study, and the NK cells will be given by vein through your central venous catheter CVC. A CVC is a sterile flexible tube and needle that will be placed into a large vein while you are under local anesthesia. Blood samples will also be drawn through your CVC. The CVC will remain in your body during treatment. Your doctor will explain this procedure to you in more detail, and you will be required to sign a separate consent form.
