Bone Marrow Transplant (BMT)

Specialized Evaluation, Treatment Planning & Long-Term Transplant Care

For some children with serious blood disorders, bone marrow failure syndromes, immune deficiencies or certain cancers, a Bone Marrow Transplant (BMT) oƯers the possibility of long- term disease control or even a cure. While the idea of a transplant can seem overwhelming, advances in transplant medicine, supportive care and donor matching have made Bone Marrow Transplantation safer and more successful than ever before. Dr. Krishna Kant Singh is a Pediatric Haematologist, Oncologist and Bone Marrow Transplant specialist with advanced fellowship training in Hemato-Oncology and BMT.

What is a Bone Marrow Transplant?

A life-saving procedure designed to restore healthy blood cell production when bone marrow becomes diseased or damaged.

Understanding Bone Marrow

Bone marrow is the soft tissue inside bones where blood cells are produced. When the bone marrow becomes diseased or damaged, it may stop producing healthy blood cells. In certain conditions, replacing unhealthy bone marrow with healthy stem cells can restore normal blood cell production.

Stem Cell Collection Sources

Despite its name, a Bone Marrow Transplant usually involves transplanting blood-forming stem cells, which may be collected from:

Bone Marrow Directly
Peripheral Blood (Bloodstream)
Umbilical Cord Blood
The goal is to replace unhealthy or damaged marrow with healthy stem cells capable of producing normal blood cells.

Vital Blood Cells Produced

Healthy bone marrow continuously produces essential components vital for body survival:

Red Blood Cells

Essential cells that continuously carry oxygen throughout the body.

White Blood Cells

Primary defense cells responsible for actively fighting infection.

Platelets

Specialized blood components that help initiate clotting to stop bleeding.

Treatment Indications

When is Bone Marrow Transplant Needed?

Not every blood disorder or cancer requires transplantation. A Bone Marrow Transplant is recommended only when it offers the best chance of long-term disease control or cure.

Clinical Guideline: Treatment decisions are rigorously based on disease characteristics, patient treatment response, and international pediatric oncology guidelines.

Blood Disorders

Certain inherited blood disorders can significantly affect a child's quality of life and long-term health.

Thalassemia Major
Sickle Cell Disease
Severe Hemoglobin Disorders
Rare Inherited Blood Disorders
Can eliminate the need for lifelong transfusions.

Marrow Failure Syndromes

Occurs when underlying diseases prevent the bone marrow from producing healthy, functional blood cells.

Severe Aplastic Anemia
Fanconi Anemia
Diamond-Blackfan Anemia
Congenital Failure Syndromes
Restores normal function when therapy is insufficient.

Childhood Leukemia

Recommended for specific high-risk or resistant pediatric leukemia cases to achieve long-term remission.

High-Risk Leukemia
Relapsed Leukemia
Chemo-Resistant Cases
High-Risk Genetic Subtypes
Provides best chance for cure in complex cases.
Clinical Scope

Immune & Rare Genetic Conditions

Immune Deficiency Disorders

Some inherited immune disorders affect the body's ability to fight infections effectively. Bone Marrow Transplant helps restore normal immune system function.

Other Rare Disorders

Bone Marrow Transplant may also be considered after careful evaluation for specific conditions:

Metabolic Disorders
Storage Disorders
Genetic Diseases
Rare Immune Conditions
Transplant Options

Types of Bone Marrow Transplant

The most appropriate type of transplant depends on the child's diagnosis, age, and overall health.

Allogeneic Transplant

Primary Approach

Stem cells are obtained from a healthy donor. This is the most common transplant performed for many childhood blood disorders and cancers.

Available Donor Sources:

Matched Sibling
Matched Unrelated
Haploidentical Donor
Umbilical Cord Blood

Autologous Transplant

In some cancers, a child's own healthy stem cells are collected before intensive chemotherapy and later returned to the body.

Primary Indication

Commonly used in selected pediatric solid tumors and lymphomas.

Donor Compatibility

Who Can Be a Bone Marrow Donor?

Finding the right donor is one of the most critical steps for transplant success.

01
Matched Sibling Highest Match

A brother or sister offers the highest probability of being a suitable genetic match for transplantation.

02
Matched Unrelated Donor Registry Search

If a sibling donor is not available, international donor registries are searched to identify compatible candidates.

03
Haploidentical Donor Half-Matched

A parent or close relative can serve as a half-matched donor, backed by advanced transplant medical procedures.

04
Umbilical Cord Blood Stem Cell Bank

Stem cells harvested from donated umbilical cord blood offer an effective alternative for selected pediatric cases.

Pre-Transplant Protocol

Bone Marrow Transplant Evaluation

Every child undergoes a multi-disciplinary assessment before proceeding with therapy.

Phase 01

Medical Assessment

Treatment history
Disease status
Organ function
Growth & nutrition
Infection history
Phase 02

Laboratory Testing

Complete Blood Count Bone Marrow Exam Blood Chemistry Liver Function Tests Kidney Function Tests Viral Screening HLA Typing Genetic Testing
Phase 03

Vital Organ Function

Essential screening of major systems prior to intensive treatment:

Heart Evaluation
Lung Function
Kidney Assessment
Liver Assessment
Initial Screening

Donor Evaluation

Potential donors undergo a thorough medical evaluation and precise tissue matching to identify the safest and most appropriate donor for the child.

The Bone Marrow Transplant Journey

Understanding each step of the treatment process helps families feel fully informed, confident, and prepared.

1

Evaluation

Step 01

The child's diagnosis, disease stage, and overall health are carefully assessed to determine whether transplantation is the most appropriate treatment option.

2

Donor Matching

Step 02

Suitable donors are identified through precise Human Leukocyte Antigen (HLA) tissue matching to ensure maximum compatibility.

3

Pre-Transplant Preparation

Step 03

Children receive conditioning therapy—which may include chemotherapy, immunotherapy, or other treatments—to prepare their body and immune system for the new stem cells.

Phase Name: Conditioning Therapy
4

Stem Cell Infusion

Step 04

Healthy donor stem cells are infused directly into a vein, similar to a regular blood transfusion. No surgery is required for the transplant procedure itself.

5

Recovery & Engraftment

Step 05

The transplanted stem cells gradually settle into the bone marrow and begin producing healthy blood cells. During this critical engraftment period, children require close clinical monitoring to prevent infections and manage any complications.

6

Long-Term Follow-Up

Step 06

Recovery continues for several months post-transplant. Regular follow-up consultations help continuously monitor essential health parameters:

Blood Counts
Immune Recovery
Organ Function
Growth & Development
Vaccination Schedule
Nutritional Status

Frequently Asked Questions

Get quick, reliable answers regarding Pediatric Bone Marrow Transplantation.

No. The transplant itself is not a surgical procedure. Healthy stem cells are infused into the bloodstream through an intravenous line, similar to a standard blood transfusion.
No. Many children with leukemia are successfully treated with chemotherapy alone. A transplant is recommended only in selected situations, such as high-risk disease, relapse, or poor response to initial treatment.
In some cases, a parent may be a suitable half-matched (haploidentical) donor. Whether a parent can donate depends on tissue matching, the child's condition, and specific transplant requirements.
Recovery varies from child to child. While initial recovery occurs over several weeks, rebuilding the immune system and returning to normal daily activities may take several months. Regular follow-up is essential throughout this period.
Not necessarily. Treatment decisions depend on the severity of the disease, availability of a suitable donor, overall health, and family preferences. A detailed evaluation helps determine whether transplantation is the most appropriate option.
