Definition

A type of transplant in which a patient receives two courses of high-dose chemotherapy, each course followed by an infusion of their own healthy blood-forming stem cells. The stem cells are collected and stored before the first high-dose chemotherapy treatment. The treatments are given weeks or months apart but are usually completed within a 6-month period. A tandem transplant is used to treat certain types of cancer, such as neuroblastoma and multiple myeloma. Also called double autologous transplant.
