Overview of Bone Marrow Transplant Procedure
A bone marrow transplant, also known as a hematopoietic stem cell transplant (HSCT), is a medical BMT procedure used to treat diseases affecting the bone marrow's ability to produce healthy blood cells. The bone marrow, found in the centre of bones, produces red blood cells, white blood cells, and platelets, essential for oxygen transport, fighting infections, and preventing bleeding. The goal of a bone marrow transplant is to replace damaged marrow with healthy stem cells, which can come from the patient's own body or a suitable donor.
Signs of Bone Marrow Transplant:
The decision to undergo a bone marrow transplant is typically based on the specific medical condition, its stage, and the patient's overall health. Some of the indications and purposes of bone marrow transplant surgery include the following:
Cancer Treatment:
- Leukemias: BMT treats acute and chronic leukaemias by providing new, healthy bone marrow and immune cells.
- Lymphomas: Used for Hodgkin's and non-Hodgkin's lymphomas to replace bone marrow after high-dose chemotherapy and radiation.
Non-Cancerous Blood Disorders:
- Aplastic Anemia: BMT replaces dysfunctional marrow with healthy stem cells.
- Sickle Cell Disease and Thalassemia: BMT offers a potential cure by replacing defective marrow with healthy cells that produce normal haemoglobin.
Genetic Disorders:
- Severe Combined Immunodeficiency (SCID): BMT replaces defective immune cells, offering a functional immune system.
- Wiskott-Aldrich Syndrome: BMT corrects the genetic defect causing immune and blood disorders.
- Fanconi Anemia: BMT treats bone marrow failure and corrects genetic abnormalities.
Autoimmune Diseases:
- Multiple Sclerosis (MS): BMT is explored to "reboot" the immune system and reduce autoimmune responses.
- Systemic Lupus Erythematosus (SLE): BMT may be considered for severe cases unresponsive to other treatments.
Solid Tumor Treatment:
- Rescue Therapy: BMT rescues bone marrow and the immune system following high-dose chemotherapy or radiation for solid tumours like neuroblastoma.
Metabolic Disorders:
- Hurler Syndrome: BMT provides healthy enzymes to replace defective ones in metabolic disorders.
- Adrenoleukodystrophy (ALD): BMT can potentially halt the progression of this neurodegenerative disorder
Failed Previous Treatment:
- Salvage Therapy: BMT is considered when initial treatments fail, or disease relapses occur.

Get A Second OpinionSteps Involved in Bone Marrow Transplant(BMT) Surgery:
During a Bone Marrow Transplant (BMT) surgery, several critical steps are undertaken to replace damaged or diseased bone marrow with healthy stem cells. The procedure involves the following key stages:
Bone Marrow Transplant Process:
- Preparative Regimen: Patients undergo high-dose chemotherapy, radiation therapy, or both to destroy existing bone marrow cells, suppress the immune system, and create space for new stem cells.
- Stem Cell Infusion: Healthy stem cells are infused into the bloodstream and travel to the bone marrow to start producing new blood cells.
- Engraftment: Transplanted stem cells settle in the bone marrow and begin generating new blood cells, monitored closely by the medical team.
- Recovery and Supportive Care: Close monitoring and supportive care are provided, including blood transfusions, antibiotics, and treatments for complications.
- Immune System Recovery: The immune system gradually recovers as new stem cells produce blood cells; patients must avoid infections during this phase.
- Monitoring and Follow-up: Regular check-ups and monitoring ensure successful recovery and management of any complications.
Key Points:
- A multidisciplinary team, including haematologists, nurses, and transplant coordinators, supports and monitors your health throughout the process.
- Risks include graft-versus-host disease (GVHD), infections, and organ damage.
- Success depends on transplant type (autologous or allogeneic), the condition treated, patient health, and donor-recipient compatibility.

A bone marrow transplant, also known as a hematopoietic stem cell transplant, is a procedure that involves restoring damaged or diseased bone marrow with healthy stem cells to treat various conditions, such as cancers, genetic disorders, and certain immune system disorders.
Bone marrow is a spongy tissue found in the centre of bones that produces blood cells, including red blood cells, white blood cells, and platelets. These cells are vital for carrying oxygen, fighting infections, and promoting clotting.
A BMT is necessary when a person's bone marrow is unable to function properly due to diseases like leukaemia, lymphoma, aplastic anaemia, or genetic disorders. It's also sometimes used to replace a faulty immune system.
Candidates for BMT include individuals with certain types of cancer, severe blood disorders, or immune system deficiencies. Eligibility depends on factors such as the patient's overall health, age, disease type, and stage.
Mortality rates remained significantly higher for at least 30 years after transplantation, resulting in a 30% lower life expectancy compared to the general population, regardless of age.
The survival rate for bone marrow transplants in India has dramatically improved, currently ranging from 80% to 90%. This is influenced by factors such as the type of transplant, underlying condition, patient age, and donor availability.
Recovery varies but usually takes several months. Patients may need to stay in the hospital for weeks and have regular follow-up visits to monitor for complications and ensure proper blood cell production.
Long-term outcomes can be very positive, with many patients achieving remission or cure. However, ongoing monitoring is essential to manage any late effects and ensure sustained health.
The recovery time for bone marrow donors varies based on the individual and type of donation. For PBSC donations, full recovery typically takes one week.
If you are between 17 and 55 and in good health, you can register as a blood stem cell donor. 17-year-olds can complete the registration process but will only be added to the registry after their 18th birthday.
