The Donor Experience
All stem-cell donors are evaluated in the IBMT clinic before the patient
receives the chemotherapy (and/or radiation) treatment that begins the
transplant process. All donors will meet with an IBMT physician. To protect
the donor's interests and confidentiality, the donor's physician will be a
physician other than the primary one caring for the stem-cell recipient
before transplant. A complete history and physical examination will be
performed, and the donation process will be explained. Furthermore,
laboratory tests, chest X-ray and EKG will be done. Then the donor will be
asked to sign the consent for the procedure. Either a bone-marrow harvest
or peripheral blood stem-cell collection will be scheduled.
Bone Marrow Harvest
Bone marrow harvests are usually done under general anesthesia, but can
also be done under epidural or spinal anesthesia. The collection takes
place in a sterile operating room. The procedure is often done as a
"same day procedure" with the donor being admitted early in the morning,
and discharged in the late afternoon or early evening. Donors are asked not
to eat or drink anything after midnight
the night before the procedure, and to report to the hospital around 6:00 am.
Some final blood tests will be
drawn and an Operating Room consent will be signed. After surgery, donors
will be taken to the recovery unit. Once they are fully awake and stable,
they will go to a nursing unit of the hospital. Then they either stay
overnight, or are released later the same day.
Many donors will be asked to donate a unit of their own blood about 2-4
weeks prior to surgery. This blood will be stored and returned to the donor
during, or immediately after, the bone-marrow collection. Blood can be
donated for this purpose at many places around the state. The IBMT
physician who does the donor physical examination will determine whether
the donation of blood is necessary. Donors are also asked not to take
aspirin-or ibuprofen-containing drugs for1-2 weeks prior to the bone marrow
harvest.
After a bone marrow harvest, donors will feel soreness in the hip areas
like they have fallen on ice or have had a bout of the flu. Tylenol®
or other pain medication will relieve most soreness. Aspirin or
ibuprofen-containing painkillers are not recommended, because they can
increase bruising. Most donors are able to return to work 1-2 days following
the procedure. Donors who do a lot of lifting or bending, may require more
time to recover. Appropriate statements for work will be supplied upon
request. Bandages that were applied at the end of surgery, should remain in
place for 48 hours.
Blood Stem Cell Donation
Peripheral blood stem cell (PBSC) donations take place in the IBMT
Clinic Apheresis Center. These collections are
done much like donations of platelets or plasma (see Apheresis
pamphlet). The procedure involves separation and collection of white cells
from the peripheral blood using a cell separator machine. Large I.V. tubes
will be placed in both arms; blood will flow from one arm into the machine,
the white cells will be collected, and the rest of the blood will be
returned to the donor through the other arm. If a donor's veins are not
adequate to allow the machine to collect at a sufficient rate, the donor
may need to have a catheter placed in a vein under the collar bone or in
the groin. In either case, a single collection will take two to four hours.
Depending upon the number of cells required and collected, this process may
be repeated two or three days in a row.
If a donor is being asked to donate "mobilized" stem cells,
daily shots of "growth factor" (Neupogen®) are
given under the skin (like insulin shots) for 4 days prior to the start of
the collections. This growth factor increases the number of stem cells in
the blood, but may also cause bone pains or headaches. Tylenol®
will relieve most of the symptoms, but occasionally stronger painkillers
are needed. These side effects will disappear rapidly after the shots have
been stopped. Donors who have a history of blood clots, stroke, or coronary
artery disease may be at increased risks for problems associated with
"growth factor" mobilized collections.
Additional Requests of Donors
Instances may occur where the donor will be asked to come back after the
original collection to donate additional blood products. Occasionally,
platelets may be needed if the patient does not respond to platelets from
blood bank donors. More frequently, additional stem cells (either bone
marrow or peripheral blood stem cells) or white blood cells ("donor
lymphocytes") will be required, because either the patient still has
low counts, or there is an increased risk for recurrence of the cancer.
Unless an emergency arises, the IBMT physicians will discuss that issue
with the donor prior to transplant.
Please discuss any concerns with your IBMT physician or the transplant
coordinator.
