• Glossary of Terms - Stem Cell Transplant Program

     

    Advance directive: Document outlining your healthcare decisions and is used if you are unable to speak (or communicate) for yourself.


    ANC: Absolute Neutrophil Count; the number of neutrophils in blood. Neutrophils are white blood cells that help the body to fight infections.


    Anemia: Decreased number of red blood cells or the amount of hemoglobin in the blood.


    Apheresis: A procedure in which stem cells are collected from your blood through a central line.

     

    Autologous Stem Cell Transplant (ASTC): A proceedure in which high dose chemotherapy and /or radiation therapy is administered followed by infusion of previously harvested stem cells.

     

    Bone Marrow: The soft, spongy material in the center of bones that produces blood cells.

     

    Colony-stimulating factor: Proteins that stimulate the production of bone marrow cells. Also known as hematopoietic growth factors


    Conditioning Regimen: Treatment with high-dose chemotherapy, sometimes in combination with high-dose radiation therapy, to prepare a patient for bone marrow or peripheral blood stem cell transplantation.


    Consent form: Document (or written description) that defines the patient’s treatment plan, including medications and the possible risks and benefits of treatment. A patient reviews and signs this form before his/her treatment can begin. 


    Cyropreservation: Freezing stem cells.


    Engraftment: When the marrow is repopulated by reinfused stem cells.


    Granulocyte: A type of white blood cell, which helps the body to fight infections; also known as a neutrophil.


    Harvest: Collection of stem cells.


    Health care proxy: A document that identifies the person you have chosen to make health care decisions for you, if you are unable to make them for yourself.


    Hematocrit: Measurement of red blood cells.


    Hematopoietic growth factors: Proteins that stimulate the development of blood cells from stem cells. Also known as colony-stimulating factors.


    Hemoglobin: A protein in red blood cells that carries oxygen from the lungs to all cells of the body. Hemoglobin gives blood its red color.
    .

    Informed consent: The process by which a patient reviews the details of his/her treatment plan in a written document, and agrees (or consents) to begin treatment.


    Infusion: The introduction of a fluid, including drugs, into the bloodstream. Also known as intravenous infusion.


    Intravenous catheter: A thin plastic tube that is inserted into a vein to allow the addition of substances to the blood.


    Leukocytes: Also known as white blood cells; divided into three main subgroups: granulocytes, lymphocytes and monocytes.


    Mucositis: Reddening and soreness of the tongue, lips mouth, throat and gastrointestinal tract from chemotherapy or radiation therapy.


    Neutropenia: When absolute neutrophil count (ANC) drops below 500.


    Neutrophil: See Granulocyte.


    Peripheral blood stem cells: Stem cells that circulate in the blood.


    Peripheral Blood Stem Cell Transplant (PBSCT): A type of ASCT in which blood stem cells are infused after high dose chemotherapy and/or radiation therapy have been given


    Platelet: Blood cell that initiates blood clotting and prevents bleeding.

     


    Stem cells: Primitive cells in the bone marrow and blood that are capable of producing mature blood cells.

     

    Thrombycytopenia: An abnormal low numbe of platelets in the blood.

     

    Stem cell harvest: A process in which cells are taken from the patient's blood and frozen for later use.
