Before you have back-up PBPC collected or you receive chemotherapy, you will require placement of a hollow plastic tube (catheter) into a large vein inside your body. This catheter will be used to draw blood and to give medications and fluids. The catheter is inserted through the skin in the upper chest and extends to a point above the right side of your heart. Your doctor will explain this procedure to you in more detail, and you will be required to sign a separate consent form for this procedure.
