Multiple myeloma (MM) lowers the number of healthy blood cells in the bone marrow. A peripheral stem cell transplant (PSCT) is a way to help the bone marrow return to normal.
Stem cells (immature, unformed cells) are taken from your own blood or bone marrow, then frozen. (Donor blood is given to you by someone else.) High dose chemotherapy is given to kill any leftover cancer in the body before the PSCT. Then, the stem cells are returned to the body. They travel to bone marrow sites and slowly repopulate all types of blood cells the body needs. After PSCT, the new cells should be cancer free and can make new, healthy cells.
Most people use their own stem cells to treat MM.
These medicines affect certain proteins that cancer cells need to grow and spread. The drugs used are:
These drugs are used with chemotherapy, and for MM that returns or is hard to treat.
