Following is a brief description of the outpatient bone marrow/stem cell transplant procedure. It’s designed to offer the most advanced treatment with a focus on patient comfort, convenience and compassion.
– Upon receipt of a referral from a primary-care physician, hematologist/oncologist or insurance plan, the patient’s records are requested and the patient is scheduled for an extensive consultation.
– It is important that patients, their families, and other caregivers are well informed and fully prepared for the outpatient stem cell transplant procedure. Included are consultations with the transplant physician and staff, videos and reading materials.
– To induce remission and determine the sensitivity of the cancer tissue. Conventional or intermediate doses of chemotherapy are given to reduce the number of tumor cells. Several cycles of chemotherapy may be required before the patient meets transplant eligibility criteria. CT scans, MRIs and other tests are usually required to determine when the patient meets the criteria.
– To further reduce the cancer tissue and to accelerate stem cell production. Mobilization therapy consists of three to five days of chemotherapy followed by growth factor administration and one to two weeks of blood monitoring and patient supportive care.
– A painless procedure in which the patient’s blood is circulated through a cell-separating machine. This device removes a fraction of the white cells, which includes the stem cells, and stores them. The cells are then frozen at minus 196 degrees centigrade until transplant time.
– To eradicate the cancerous tissue prior to the stem cell transplantation. The patient receives two to six days of intense chemotherapy. After each full-day session, if the patients are clinically stable, they return home until the following day.
– Approximately 48 hours after the completion of the high-dose chemotherapy, the patient’s previously donated stem cells are reinfused into the bloodstream. The stem cells naturally migrate to the bone marrow, where they begin to multiply and mature into red and white cells and platelets.
– During the weeks that follow the transplant, the patient’s own immune system and blood functions gradually recover to a normal level. Most patients return to normal daily activity within four to eight weeks.
– For the first three months post-transplant, visits are scheduled frequently, and thereafter at six months and annually.
In addition, we provide extended home health care (including weekends and holidays) as well as hospital care, if needed.

Q: What is bone
marrow and what are stem cells?

Bone marrow is
the soft, sponge-like material found in the bones. Its
main function is to produce primitive or immature cells called
stem cells (also called "progenitor cells").
These cells have the ability to divide into more stem cells or
into white blood cells (WBCs), red blood cells (RBCs), and
platelets, depending upon the body's needs at that moment.
White blood cells
(also called "leukocytes") help the body defend itself
against infection and other disease, by destroying
"foreign" substances such as bacteria or viruses.
When infection is present, the body increases the production of
the WBC. When the number of WBC in the blood is low, the
body has a more difficult time warding off infection.
Red blood cells
(also called "erythrocytes") carry oxygen, with the
aid of a protein called hemoglobin, from the lungs to cells in
all parts of the body. Oxygen helps process the nutrients
from the food that we eat. RBCs also carry back carbon dioxide
(considered "waste material") from the cells to the
lungs. When the number of RBC in the blood is low, a
condition called anemia results.
Platelets help
the blood to clot and thus, preventing bleeding. Low
number of platelets in the blood (a condition called
thrombocytopenia) may cause easy bruising and bleeding.
In adults, stem
cells can be found mostly in marrows of the bones of the skull,
back, chest, hips and upper arms and legs. In children,
they can be found throughout most of the marrows. Stem
cells, however, can also be found circulating in the blood
throughout the body and are called peripheral blood stem cells.
Q: How are
bone marrow and stem cells obtained for the transplant?
Bone marrow and
stem cells can be obtained or "harvested" from the
patient (autologous) or from another individual (allogeneic),
but are always collected before very high doses of anti-cancer
drugs (chemotherapy) and/or high energy rays (radiotherapy) are
administered.
Bone marrow is
usually taken from the hip bones (pelvis) using a large needle
or a special syringe inserted several times into the pelvic bone
through small incisions to draw out the marrow. The
"harvested" marrow is then processed to remove blood
and bone fragments. This process of obtaining stem cells is also
called aspiration, which may require local or general
anesthesia, and is usually done in the operating room. It
may require the patient to stay in the hospital for 1-2 nights,
but some hospitals can perform a bone marrow harvest as an
outpatient. The site of the needle puncture will be tender
for about a week with slight scars forming. The patient
or donor may feel some mild stiffness and soreness but can be
lessened through exercise and pain medication.
A newer method of
collecting or harvesting stem cells is called apheresis or
leukapheresis. Blood is obtained through a line (central
venous catheter) inserted into a large vein and passed through a
machine that removes stem cells. The rest of the blood is
returned to the patient. The process may take 2 to 4
hours, and usually does not require staying in the hospital
overnight. There are fewer stem cells circulating in the
blood when compared to those found in the marrow.
Transplant physicians are therefore looking into ways to
increase the number of stem cells that can be harvested. By
giving the patient "growth factors" (substances that
are naturally produced by the body but can also be made in
laboratories), the transplant physicians help stimulate the body
to make more stem cells. Since only a small amount of
marrow or stem cells are removed, the procedure seldom poses
significant problems or results in bad side effects.
Q:
How
are stem cells used for the transplant?
Once the stem
cells are obtained, the marrow or stem cells are either
preserved and frozen until needed (in an autologous transplant)
or are given to the recipient almost immediately (in an
allogeneic transplant).
The patient is
then given very high doses of anti-cancer drugs and/or radiation
(called "conditioning") to get rid of the cancer cells
throughout the body; to make space for the new marrow and; in an
allogeneic transplant, to reduce the risk of the patient
rejecting the cells or marrow taken from another person.
The bone marrow or stem cells that were previously collected are
given to the patient through a central venous catheter to help
re-grow normal blood cells and reduce the chance of severe
infection, bleeding, or anemia.
Q: Is there
any evidence of success for stem cell/bone marrow transplant?
As improvements
are being made in the way the procedure is done, stem cell/bone
marrow transplantation is becoming more commonly accepted and
effectively used in treating many cancers and leukemias.
Researchers are finding better results in the use of stem
cell/bone marrow transplant in patients with breast cancer,
Hodgkin's disease, non-Hodgkin's lymphoma, leukemia, multiple
myeloma, neuroblastoma and testicular cancer. |
