Comprehensive treatment for optimun results

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.

EvaluationUpon 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.

Education 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.

InductionTo 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.

MobilizationTo 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.

Harvest and Storage 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.

High-Dose ChemotherapyTo 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.

TransplantationApproximately 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.

Recovery 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.

Follow-upFor 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.

We know what you and your family are going through. We know how precious life is. That’s why you should choose South Florida Bone Marrow/Stem Cell Transplant Institute. We invite you to call 561-752-5522 to schedule an appointment.


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. 



History of Bone Marrow Transplants

Bone marrow/stem cell transplant procedures have been around since the 1970's, but were not widely accepted in the United States until the mid to late '80's.  Today, BM/SCTs are utilized to treat a variety of blood disorders and cancers including acute and chronic myeloid leukemia, multiple myeloma, Hodgkin's disease, non-Hodgkin's lymphoma.

The beneficial effects of BM/SCTs have been well documented through outcomes studies. For each disorder, the disease-free survival rates for transplant patients are significant when compared to patients receiving conventional chemotherapy.
