Bone marrow transplant (BMT), also known as a stem cell transplant, is a life-saving treatment for blood cancers, immune disorders, and genetic blood diseases such as leukaemia, lymphoma, aplastic anaemia, and thalassemia.
This guide explains the types of bone marrow transplants, donor matching, recovery, survival outcomes, risks, and why India has become a leading destination for affordable and advanced BMT treatment.

What is Bone Marrow, and Why is it Essential?
Bone marrow is the soft, spongy tissue inside large bones that produces blood cells including red blood cells, white blood cells, and platelets.
- Red blood cells carry oxygen throughout the body
- White blood cells fight infections
- Platelets help blood clot properly
Healthy bone marrow is essential for maintaining immunity, healing, and overall body function.
Why is a Bone Marrow Transplant Needed?
When bone marrow becomes damaged or diseased, it may fail to produce healthy blood cells. In such cases, a bone marrow transplant may become necessary.
A BMT replaces diseased marrow with healthy stem cells either from the patient or a donor to restore normal blood cell production.
Who Needs a Bone Marrow Transplant?
Conditions Commonly Treated with BMT
- Acute Lymphoblastic Leukaemia (ALL)
- Acute Myeloid Leukaemia (AML)
- Chronic Myeloid Leukaemia (CML)
- Myelodysplastic Syndromes (MDS)
- Lymphoma
- Multiple Myeloma
- Aplastic Anaemia
- Thalassemia Major
- Sickle Cell Disease
- Severe Combined Immunodeficiency (SCID)
Age-Based Eligibility Considerations
BMT eligibility depends more on organ function and overall health than age alone.
- Children often tolerate intensive conditioning regimens well
- Adults aged 18–55 are common candidates
- Patients aged 55–75 may qualify for reduced-intensity transplants
Benefits of a Bone Marrow Transplant
- Improved survival rates
- Restoration of healthy blood cells
- Reduced infection risk
- Potential cure for several blood disorders
- Improved quality of life
Types of Bone Marrow Transplants
| Transplant Type | Description |
|---|---|
| Autologous Transplant | Uses the patient’s own stem cells |
| Allogeneic Transplant | Stem cells from a related or unrelated donor |
| Syngeneic Transplant | Stem cells from an identical twin |
| Haploidentical Transplant | Stem cells from a half-matched family donor |
Autologous vs. Allogeneic Transplant
| Parameter | Autologous | Allogeneic |
|---|---|---|
| Stem Cell Source | Patient’s own cells | Matched donor |
| GVHD Risk | None | Moderate to high |
| Hospital Stay | 2–3 weeks | 4–6 weeks |
| Relapse Risk | Higher | Lower |
The Donor Matching Process
What is HLA Matching?
Human Leukocyte Antigen (HLA) matching helps reduce the risk of graft rejection and graft-versus-host disease (GVHD).
Types of Donors
- Matched sibling donor
- Matched unrelated donor
- Haploidentical donor
- Cord blood donor
The Matching Process
- HLA typing blood test
- Testing family members first
- Registry search if needed
- High-resolution compatibility testing
- Donor medical fitness evaluation
The Bone Marrow Transplant Procedure
- Evaluation & Preparation
Comprehensive medical assessment and transplant planning. - Stem Cell Collection
Collection from patient or donor. - Conditioning Regimen
High-dose chemotherapy and/or radiation. - Stem Cell Infusion
Healthy stem cells infused into bloodstream. - Recovery & Monitoring
Close monitoring for infections and complications.
BMT Recovery Timeline
| Timeline | What Happens |
|---|---|
| Days 0–7 | Stem cell infusion and monitoring |
| Days 7–14 | Lowest blood counts and infection risk |
| Days 14–30 | Engraftment begins |
| Months 1–3 | Hospital discharge and outpatient follow-up |
| Months 3–6 | Immune system rebuilding |
| Months 6–12 | Return to normal activities |
Potential Side Effects of Bone Marrow Transplant
- Nausea and vomiting
- Fatigue and weakness
- Infections
- Graft-versus-host disease (GVHD)
- Organ damage
- Infertility
- Secondary cancers
- Psychological stress
Understanding BMT Risks & Complications
- Graft failure
- Veno-occlusive disease (VOD)
- Mucositis
- Haemorrhagic cystitis
- Pulmonary complications
How to Manage and Minimise Side Effects
- Medication management
- Supportive care and nutrition
- Infection prevention strategies
- GVHD management
- Fertility preservation when needed
BMT Survival Rates & Long-Term Outcomes
Factors Influencing Survival
- Disease type and stage
- Patient age and health
- Donor compatibility
- Conditioning intensity
- GVHD management
General Survival Statistics
| Condition | Estimated Survival / Cure Rate |
|---|---|
| Multiple Myeloma | 40–60% 5-year survival |
| Acute Leukaemia | 40–70% disease-free survival |
| Thalassemia Major | 85–90% cure rates |
| Aplastic Anaemia | 80%+ long-term survival |
