What are bone marrow and haematopoietic stem cells?
Bone marrow is a soft, spongy tissue found inside the bones. It contains the cells from which blood cells originate — the so-called "haematopoietic" cells.
As they divide, haematopoietic stem cells can produce more blood stem cells or turn into "red blood cells – erythrocytes", "white blood cells – leucocytes" or "platelets" that enter the bloodstream. The vast majority of haematopoietic stem cells are found in the bone marrow, but some are also found in umbilical cord blood and in the bloodstream.
Wherever they are located, the cells collected can be used for a transplant.
What is a bone marrow transplant?
A bone marrow or stem cell transplant is carried out to replace the healthy cells destroyed by cancer treatment. The bone marrow or stem cells taken from the donor are frozen and carefully stored; meanwhile, the patient receives high-dose chemotherapy and, sometimes, total body irradiation.
There are three types of transplant:
Autologous transplant: this involves collecting the patient's own stem cells from their bone marrow or bloodstream.
Syngeneic transplant: the graft consists of stem cells from an identical twin.
Allogeneic or haploidentical transplant: the graft consists of stem cells taken from siblings or close relatives. Where there is a match, an unrelated donor can also be used.
How does a bone marrow transplant work?
First, before the cells are transplanted, the person's disease must be treated. The patient is first treated using the method defined by the doctors. Then, with the help of certain medicines, stem cells are collected and frozen. Generally, a week after the healthy cells are collected, the patient is given high-dose medicines. After these high-dose medicines are given, the stored healthy stem cells are reinfused into the patient. This approach allows the stem cells damaged during treatment to regenerate.
Does an autologous transplant carry risks?
When the patient's stem cells are collected, there is a risk that diseased cells will be collected too. In other words, reinfusing the frozen stem cells into the patient may lead to a relapse of the disease because of the presence of diseased cells.
Is an allogeneic transplant dangerous?
An allogeneic transplant exposes the patient to the donor's immune system. This is an advantage, but allogeneic transplantation carries a risk of immune incompatibility. This can cause a reaction between the donor's immune system and the organs of the patient receiving the stem cells. The liver, skin, bone marrow and intestines can then be damaged. This situation, which requires treatment, is called "graft-versus-host disease (GVHD)". It damages organs and can lead to organ failure. An autologous transplant does not carry this risk.
In an allogeneic or haploidentical transplant, are the donor's stem cells compatible with the patient's?
Doctors mainly use the stem cells that most closely resemble the patient's. In this way, possible side effects can be kept to a minimum. On the surface of human cells there are various proteins called human leucocyte antigens (HLA). These proteins are determined by a blood test called HLA typing.
In most cases, the success of an allogeneic transplant depends on the degree of compatibility between the HLA antigens of the donor's stem cells and the HLA antigens of the recipient. The higher the number of matching HLA antigens, the greater the likelihood that the recipient's body will accept the donor's stem cells. In general, a good level of compatibility between donor and recipient stem cells minimises the risk of developing the complication known as graft-versus-host disease (GVHD).
The likelihood of a match at the HLA typing level is higher in a close relative, particularly a sibling, than in an unrelated person. Only about 25 to 35% of patients have an HLA-matched sibling. The likelihood of finding HLA-matched stem cells from an unrelated donor is slightly higher – around 50%. When the donor and recipient belong to the same ethnic group and origin, HLA compatibility with unrelated donors improves considerably. The number of donors is generally increasing; conversely, people from certain ethnic groups have less chance of finding a compatible donor. A database bringing together all volunteer donors can help in finding an unrelated donor.
Identical twins have the same genes, and therefore the same HLA antigens. This is why the patient's body will accept a transplant from their identical twin. However, as identical twins are not numerous, this type of transplant is performed fairly rarely.
How is bone marrow collected for a transplant?
The stem cells used in bone marrow transplants are collected from the liquid centre known as the "marrow". The marrow collection procedure, usually called "harvesting", is similar for all three types of bone marrow transplant (autologous, allogeneic, haploidentical). This procedure takes place under general anaesthesia or under a local anaesthetic that numbs the donor from the lower back downwards. To collect the marrow, needles are inserted into the bone marrow at the iliac bone. The harvest lasts about an hour.
The bone marrow collected is processed to remove any bone and blood residue. A preservative may be added to the marrow collected, and the stem cells are then frozen to be stored until they are used. This method is called cryopreservation. Thanks to this cryopreservation method, stem cells can be stored for many years.
How are peripheral blood stem cells collected?
Peripheral blood stem cells are collected from the bloodstream. The cells used for the transplant are collected using a procedure called "apheresis or leukapheresis". To increase the number of stem cells in the bloodstream, a treatment may be given to the donor 4 to 5 days before apheresis. For apheresis, blood is drawn from a large vein in the arm or through a central venous catheter (a flexible tube inserted into a large vein in the neck, chest or pelvic region). The blood passes through a machine that collects the stem cells. The blood is then returned to the donor, while the cells collected are stored. Apheresis generally lasts 4 to 6 hours. The stem cells are frozen until they are used in the recipient.
Does donating bone marrow carry risks?
In general, since only a very small amount of marrow is collected, this donation does not pose a serious problem. Most of the associated risks come from complications related to the anaesthesia used during the procedure.
The area where the bone marrow was collected may remain swollen and hard for a few days. The donor may feel tired during this period. The donor's body replaces the lost bone marrow within a few weeks, but the recovery time needed may vary from donor to donor. Some people can resume their daily activities in 2 to 3 days, while others need 3 to 4 weeks to regain their strength.
Does donating peripheral blood stem cells carry risks?
Apheresis generally causes only minimal discomfort. The person may feel weak, have chills, numbness of the lips and cramps in the hands. Unlike a bone marrow transplant, no anaesthesia is needed for peripheral blood stem cells. The medicine used to stimulate the passage of stem cells from the marrow into the bloodstream can cause bone and muscle pain, headaches, tiredness, nausea, vomiting and/or sleep disturbances. The side effects generally disappear 2 to 3 days after the last dose of the medicine.
What happens when the stem cells are transplanted into the patient?
The stem cells enter the bloodstream, then settle in the bone marrow and begin to produce red blood cells, white blood cells and platelets. These cells generally begin to produce blood 2 to 4 weeks after the transplant. Doctors monitor this process through frequent blood tests. However, the complete reconstitution of the immune system takes longer. This period is generally a few months for recipients of an autologous transplant and one to two years for recipients of an allogeneic or haploidentical transplant.
What are the possible side effects of a bone marrow transplant?
The main risk associated with these two treatment methods is increased susceptibility to infections and bleeding, due to the high-dose anticancer treatment. Doctors may give patients antibiotics to prevent or treat infections. A platelet transfusion may be needed to prevent bleeding, and a red blood cell transfusion to treat anaemia. Patients who have had a bone marrow or peripheral blood stem cell transplant may experience short-term side effects such as nausea, vomiting, tiredness, loss of appetite, mouth ulcers, hair loss and skin reactions.
Possible long-term side effects are generally related to the chemotherapy and radiotherapy given before the transplant. They include infertility (the person being unable to have a child biologically), cataracts (clouding of the lens), secondary cancers, and damage to the liver, kidneys, lungs and/or heart. The risks of complications and their severity depend on the patient's treatment and must be managed with the doctor who prescribes the treatment.
What is a "mini-transplant"?
A mini-transplant is a type of allogeneic transplant (known as a non-myeloablative or reduced-intensity transplant). Clinical studies are currently under way for the treatment of various types of cancer, including leukaemia, lymphoma, multiple myeloma and other blood cancers.
In a mini-transplant, lower doses of chemotherapy or radiotherapy are used to prepare the patient for the allogeneic transplant. The low doses of drugs and radiation destroy part of the patient's bone marrow, without damaging it completely. It also reduces the number of cancer cells and weakens the immune system to prevent rejection of the graft.
Unlike a conventional bone marrow transplant or a peripheral blood stem cell transplant, after a mini-transplant the donor's cells and the patient's cells continue to coexist for a short period. When the bone marrow starts to function, the donor's blood cells trigger the graft-versus-tumour (GVT) reaction and destroy the cancer cells still present after the drug treatment and/or radiotherapy. To strengthen the GVT effect, white blood cells from the donor may be given to the patient. This procedure is called "donor lymphocyte infusion".
