Gallbladder: The pear-shaped organ that sits below
your liver. Bile is stored in the gallbladder.
Gastrointestinal: Refers to the digestive tract and/or
the intestines.
Gene: Collections of DNA segments in each cell that
contains our hereditary information and determines the traits
we get from past generations. There are approximately 30,000
genes in each human cell containing a nucleus.
General
Anesthesia: This form of anesthesia causes
people to lose consciousness. People undergoing general
anesthesia are unaware of the surgical procedure or any other
sensations.
Genetic: Inherited; having to do with information
that is passed from parents to children through DNA that make
up our genes.
GM-CSF: See Granulocyte-macrophage - colony stimulating factor
Grade: A way to rate the aggressiveness or malignancy
of a tumor. The grade helps determine the best treatment for
the cancer. The higher the grade, the more aggressive a tumor
is.
Graft
Failure: A condition that may happen after a stem
cell transplant where the donated stem cells are present, but
function very poorly or not at all.
Graft
Rejection: A condition that may happen to people
who receive someone else’s blood stem cells or marrow in a
transplant. The patient experiences a loss of donor cells
through an active (often the recipient’s immune system)
process. It is most often seen in patients with aplastic
anemia.
Graft vs. Host Disease (GVHD): A complication of stem
cell transplantation in patients receiving stem cells from
another person. The newly transplanted immune system
identifies the patient’s body as foreign and attacks it,
resulting in varying degrees of damage to three target organs:
the skin, gastrointestinal tract, and liver.
Granulocyte: A type of white blood cell also
called a neutrophil. These cells are important in fighting
bacterial and fungal infections.
Granulocyte-macrophage - colony stimulating factor
(GM-CSF): Sold as Sargramostim or Leukine, this growth
factor is used like G-CSF to speed the recovery of the
granulocyte count following the administration of
chemotherapy.
Growth
Factor: Another term used when referring to
medications that stimulate the production of blood cells.
Filgrastim is an example of a growth factor that stimulates
granulocyte production. (See Filgrastim)
