What is autologous bone marrow transplantation?
Listen to pronunciation. (aw-TAH-luh-gus bone MAYR-oh TRANZ-plant) A procedure in which a patient’s healthy stem cells (blood-forming cells) are collected from the bone marrow before treatment, stored, and then given back to the patient after treatment.
What is the difference between an autologous and allogeneic bone marrow transplant?
Autologous: Auto means self. The stem cells in autologous transplants come from the same person who will get the transplant, so the patient is their own donor. Allogeneic: Allo means other. The stem cells in allogeneic transplants are from a person other than the patient, either a matched related or unrelated donor.
What is autologous hematopoietic stem cell transplantation?
Autologous hematopoietic stem cell transplantation (aHSCT) is a type of bone marrow transplantation that attempts to reset the immune system, which is responsible for damaging the brain and spinal cord in multiple sclerosis.
What is the survival rate after a bone marrow transplant?
A 2016 study of over 6,000 adults with AML found that people who received an autologous bone marrow transplant had a 5-year survival rate of 65%. For those who received an allogenic bone marrow transplant, it was 62%.
How autologous transplant is done?
In an autologous transplant, your own blood-forming stem cells are collected. You are then treated with high doses of chemotherapy. The high-dose treatment kills the cancer cells, but it also gets rid of the blood-producing cells that are left in your bone marrow.
What is autologous transplant?
An autologous stem cell transplant uses healthy blood stem cells from your own body to replace your diseased or damaged bone marrow. An autologous stem cell transplant is also called an autologous bone marrow transplant.
What are the three types of bone marrow transplants?
The different types of BMT include the following:
- Autologous bone marrow transplant. The donor is the patient himself or herself.
- Allogeneic bone marrow transplant. The donor shares the same genetic type as the patient.
- Umbilical cord blood transplant.
What is the age limit for bone marrow transplant?
People who meet certain criteria may be considered for bone marrow transplant. At Mayo Clinic, doctors will consider selected patients over 65 years of age, depending on their overall physical health.
How long does autologous bone marrow transplant take?
The transplant typically occurs about two days after these therapies are complete. The frozen stem cells are thawed and then re-infused into the bloodstream, similar to a blood transfusion. The procedure typically takes about an hour.
How many stem cells are needed for a bone marrow transplant?
While the minimum number of hematopoietic stem cells for a successful transplantation has been established, there is no definite information on the optimum number or the maximum number of stem cells. It is generally agreed that a minimum dose of 2.5 x 10(6) CD34+ cells is necessary for successful engraftment.
How does autologous transplant work?
How long does recovery take in an autologous transplant?
Although you might be allowed home a couple of weeks after an autologous stem cell transplant, it takes 3 to 6 months for you to recover completely. This can be a difficult time physically and emotionally.
What is an allogenic?
(A-loh-JEH-nik) Taken from different individuals of the same species.
Can you live a normal life after a bone marrow transplant?
Some 62% of BMT patients survived at least 365 days, and of those surviving 365 days, 89% survived at least another 365 days. Of the patients who survived 6 years post-BMT, 98.5% survived at least another year.
What are the long-term side effects of a bone marrow transplant?

- Acute lymphocytic leukemia.
- Acute myelogenous leukemia (AML)
- Adrenoleukodystrophy.
- Amyloidosis.
- Aplastic anemia.
- Bone marrow failure syndromes.
- Chronic lymphocytic leukemia.

How does autologous cell therapy work?
Undergoing an autologous stem cell transplant involves: Taking medications to increase the number of stem cells in your blood. You’ll receive medications that cause your stem cells to increase in number and to move out of your bone marrow and into your blood, where they can be easily collected.
¿Qué es el Trasplante Autólogo de médula ósea?
El Trasplante Autólogo de Médula Ósea es un procedimiento en el cual el donante es el mismo paciente.
¿Qué es la médula ósea?
La médula ósea es un tejido esponjoso que se encuentra dentro de algunos huesos. Su función es producir células sanguíneas. Si tu médula ósea no está funcionando adecuadamente debido a un cáncer u otra enfermedad, puedes recibir un trasplante de células madre.
¿Cómo se cura el cancer de la médula ósea?
Esto se puede hacer de dos maneras: Tratamiento ablativo (mieloablativo) — Se administran altas dosis de quimioterapia, radioterapia o ambas para destruir cualquier tipo de células cancerosas. Esto también destruye toda la médula ósea sana que queda y permite que crezcan nuevas células madre en la médula ósea.
¿Qué es el procedimiento de reemplazar la médula ósea dañada o destruida por células madre?
Es un procedimiento para reemplazar la médula ósea dañada o destruida por células madre de médula ósea sana. La médula ósea es el tejido graso y blando que se encuentra dentro de los huesos. La médula ósea produce glóbulos rojos. Las células madre son células inmaduras en la médula ósea que dan origen a todas las células sanguíneas diferentes.
