A bone marrow transplant delivers healthy bone marrow stem cells into the patient. It replaces bone marrow that is either not working properly or has been destroyed (ablated) by chemotherapy or radiation.

DescriptionBone marrow is the soft, fatty tissue inside your bones. Stem cells are immature cells in the bone marrow that give rise to all of your blood cells. Your blood is made of:
In a bone marrow transplant, you will receive healthy stem cells after your own bone marrow has been destroyed.
There are three kinds of bone marrow transplants:
Many patients get high doses of chemotherapy, radiation, or both, before the bone marrow transplant. This is called ablative (or myeloablative) treatment. It kills any cancer cells that might remain, and it makes room in the bone marrow for the new stem cells to grow.
Today, some patients are getting less chemotherapy and radiation before their transplant. This is called a reduced intensity (nonmyeloablative) or "mini" transplant.
After the patient gets chemotherapy and radiation, a doctor will do the stem cell transplant. The patient gets the stem cells through a tube called a central venous catheter. The process is similar to receiving a blood transfusion. The cells go right into the bloodstream and find their own way to the bone marrow. Usually, no surgery is required.
Donors may have minor surgery to collect their bone marrow and stem cells. For a bone marrow harvest, they will be unconscious and pain-free (under general anesthesia) while their bone marrow is removed from their hip bone. In many cases however, stem cells can be collected right from the blood. The donor will first receive injections for a few days.
When receiving stem cells, a patient may have these symptoms:
Bone marrow or stem cell transplant may be recommended for:
All bone marrow transplants have risks. The risk is higher or lower depending on many factors. Some of these factors are:
Complications you may have are:
Your health care provider will ask you about your health record and do a physical exam. You will also have many tests before your treatment begins.
Your doctor or nurse should discuss the emotional stress of having a bone marrow transplant. You may want to meet with a mental health counselor talk. Talking with your family and children to help them understand and prepare is important.
You will need to make plans for when you have the transplant. Items to consider are:
You may need to find housing for yourself or your family near the hospital.
Before the transplant, one or two catheters are inserted into larger blood vessels, usually in the neck, for you to receive treatments, fluids, and sometimes nutrition.
After the ProcedureBone marrow transplant patients usually go to medical centers, or hospitals, that specialize in this treatment. Most times the patient will stay in a bone marrow transplant unit in the center to limit their chance of getting an infection.
Some patients who get autologous or non-myeloablative allogeneic transplants do not have to stay in the hospital or medical center. They can get the transplant as an outpatient.
Some patients may have part of their autologous or allogeneic transplant done as an outpatient.
Most patients will be in the hospital for 4 to 6 weeks. During this time, you will be isolated and watched closely because of the increased risk of infection.
While you are in the hospital, these things may happen:
How well you do after transplant greatly depends on these things:
Possible results of a bone marrow transplant are complete cure of the illness being treated, a partial cure, or death. Death may be caused by complications of the bone marrow transplant or because the transplant did not work to treat the illness.
If the transplant works, you can go back to most of your normal activities as soon as you feel well enough. Most times it takes up to 12 months to recover fully.

A bone marrow transplant is a procedure to replace damaged or destroyed bone marrow with healthy bone marrow stem cells.

DescriptionThere are three kinds of bone marrow transplants:
Before the transplant, chemotherapy, radiation, or both may be given. This may be done in two ways:
A stem cell transplant is done after chemotherapy and radiation is complete. The stem cells are delivered into your bloodstream through a tube called a central venous catheter. The process is similar to getting a blood transfusion. The stem cells travel through the blood into the bone marrow. Usually, no surgery is required.
In many cases donor stem cells can be collected directly from the person's blood. Surgery is not needed. The donor will first receive injections for a few days.
Minor surgery may be needed to collect bone marrow and stem cells from a donor. This is called a bone marrow harvest. The surgery is done under general anesthesia, which means the donor will be asleep and pain-free during the procedure. The bone marrow is removed from the hip bones.
Why the Procedure Is PerformedA bone marrow transplant replaces bone marrow that is either not working properly or has been destroyed (ablated) by chemotherapy or radiation.
Your doctor may recommend a bone marrow transplant if you have:

Possible complications of a bone marrow transplant depend on many things, including:
Complications can include:
Your health care provider will ask you about your medical history and do a physical exam. You will have many tests before your treatment begins.
Before your transplant, you will have one or two tubes, called catheters, inserted into a blood vessel in your neck. This tube allows you to receive treatments, fluids, and sometimes, nutrition.
Your doctor or nurse should discuss the emotional stress of having a bone marrow transplant. You may want to meet with a mental health counselor. It is important to talk to your family and children to help them understand what to expect.
You will need to make plans to help you prepare for the procedure and handle tasks after your transplant. Things to consider include:
You may need to find housing for yourself or your family near the hospital.
After the ProcedureA bone marrow transplant is usually done in a hospital or medical center that specializes in such treatment. Most of the time, you will stay in a special bone marrow transplant unit in the center to limit your chance of getting an infection.
All or part of an autologous or allogeneic transplant can be done on an outpatient basis. This means you do not have to stay in the hospital or medical center.
How long you stay in the hospital depends on how much chemotherapy or radiation you received, the type of transplant, and your medical center's procedures. While you are in the hospital, you will be isolated because of the increased risk of infection. The health care team will closely monitor your blood count and vital signs.
While you are in the hospital you may:
How well you do after transplant greatly depends on:
A bone marrow transplant may completely or partially cure your illness. If the transplant is a success, you can go back to most of your normal activities as soon as you feel well enough. Most times it takes up to 1 year to recover fully.
Complications or failure of the bone marrow transplant can lead to death.

it is called an autologous bone marrow transplant
Autologous bone marrow transplant
Autologous = own marrow Allogeneic = transplant from a related (or tissue matched) donor. Syngeneic = transplant from an identical twin.
The first successful bone marrow transplant was in 1973.
