Advanced Care & Support with WEGOVITA in Germany
A bone marrow transplant (BMT)—also known as a stem cell transplant—is a life-saving procedure for patients with blood cancers, severe bone marrow disorders, and genetic diseases. The treatment replaces diseased or damaged bone marrow with healthy stem cells, helping the body regenerate its ability to produce essential blood cells.
At Health is Your Journey with WEGOVITA, we help international patients access Germany’s leading bone marrow transplant centers, providing expert hematologists, cutting-edge medical technology, and personalized pre- and post-transplant care.
Bone marrow is a soft, spongy tissue found inside large bones such as the hip, thigh (femur), and sternum. It serves as the body’s blood cell factory, producing three essential types of blood cells that are vital for overall health and survival:
Red blood cells (RBCs): Transport oxygen from the lungs to tissues and remove carbon dioxide. A lack of RBCs leads to anemia, causing fatigue, dizziness, and shortness of breath.
White blood cells (WBCs): Form the immune system’s first line of defense, protecting against bacteria, viruses, and infections. Low WBC counts result in increased infection risks.
Platelets: Help blood clot to prevent excessive bleeding from injuries or internal damage. Without enough platelets, patients may experience frequent bruising, nosebleeds, or uncontrolled bleeding.
Bone marrow also houses hematopoietic stem cells (HSCs)—immature cells that can develop into any of the three blood cell types. When bone marrow is damaged or diseased, these cells can no longer function properly, leading to serious or life-threatening complications.
A bone marrow transplant (BMT) is required when a patient’s bone marrow can no longer produce healthy blood cells due to:
Blood Cancers (Leukemia & Lymphoma): The uncontrolled growth of cancerous blood cells replaces normal bone marrow function, preventing the production of healthy cells.
Bone Marrow Failure Syndromes: Conditions such as aplastic anemia or myelodysplastic syndromes (MDS) cause bone marrow to stop producing blood cells entirely.
High-Dose Chemotherapy or Radiation Therapy: Cancer treatments can damage or destroy bone marrow, requiring a transplant to replenish lost stem cells.
Inherited Blood Disorders:Genetic diseases like sickle cell anemia and thalassemia result in defective red blood cells that require replacement through transplantation.
Severe Immune System Deficiencies: Rare disorders such as Severe Combined Immunodeficiency (SCID) leave patients with non-functional immune systems, making them highly susceptible to infections.
A bone marrow transplant is recommended for patients with:
Leukemia (AML, ALL, CML, CLL): Cancer of the blood and bone marrow.
Lymphoma (Hodgkin’s & Non-Hodgkin’s Lymphoma): Affects the lymphatic system.
Multiple Myeloma (MM): Affects plasma cells in the bone marrow.
Myelodysplastic Syndromes (MDS): Pre-leukemic conditions leading to bone marrow failure.
Aplastic Anemia: The bone marrow stops producing enough blood cells.
Sickle Cell Disease: Causes misshapen red blood cells, leading to oxygen deprivation.
Thalassemia: A genetic disorder requiring lifelong blood transfusions.
Severe Combined Immunodeficiency (SCID) : A life-threatening immune disorder in infants.
Patients receiving high-dose chemotherapy or radiation therapy may need a bone marrow transplant to regenerate healthy blood cells.
Bone marrow transplants (BMT) can be classified into four main types based on the source of the stem cells. The choice of transplant depends on the patient’s condition, disease severity, donor availability, and risk factors.
An autologous bone marrow transplant involves collecting the patient’s own stem cells before high-dose chemotherapy or radiation therapy. These healthy cells are frozen and stored, then reinfused after treatment.
Best for patients undergoing chemotherapy – Used when chemotherapy is expected to damage the bone marrow
Lower risk of rejection or graft-versus-host disease (GVHD) – Since the stem cells come from the patient, the immune system recognizes them as “self”.
Commonly used for: Multiple myeloma, Lymphomas (Hodgkin’s and non-Hodgkin’s lymphoma), Certain solid tumors, such as neuroblastoma
Limitations: Autologous transplants do not replace the immune system, so if cancer is present in the collected cells, it could return after transplantation. To reduce this risk, the cells are often treated before reinfusion.
An allogeneic bone marrow transplant uses stem cells from a donor whose tissue type closely matches the patient’s. The donor can be:
A sibling or family member (related donor) – The best match is often a brother or sister, who has a 25–30% chance of being a full match.
An unrelated donor – If no family match is available, patients can receive cells from a matched unrelated donor (MUD) found through global bone marrow registries.
Higher risk of rejection and GVHD – Since the new stem cells come from another person, the body may recognize them as foreign and attack them.
Advantages of Allogeneic BMT:
Replaces both blood cells and the immune system – This is crucial for patients with genetic disorders and blood cancers.
Graft-versus-Leukemia (GVL) effect – The new immune system attacks any remaining cancer cells, reducing relapse risk.
Commonly used for:
Leukemia (AML, ALL, CML, CLL)
Severe aplastic anemia
Inherited blood disorders (thalassemia, sickle cell disease)
Myelodysplastic syndromes (MDS)
Limitations:
Patients require strong immune suppression to prevent GVHD.
There is a risk of graft failure if the new cells don’t properly engraft.
A haploidentical transplant is a type of allogeneic transplant where the donor is only a 50% genetic match. It is an innovative option for patients who do not have a full match in their family or donor registries.
Expands donor availability – Parents, children, and even half-matched siblings can serve as donors.
Increasingly used for high-risk leukemia and bone marrow failure syndromes.
Often the best option in urgent cases where a fully matched donor cannot be found in time.
Advancements in haploidentical transplants:
Modern immune suppression techniques and graft manipulation have significantly improved success rates.
Patients receive post-transplant cyclophosphamide, a drug that prevents severe GVHD while preserving immune function.
Commonly used for:
High-risk leukemias (AML, ALL)
Aplastic anemia
Patients without a fully matched donor
Limitations:
Still carries a higher risk of rejection than fully matched allogeneic transplants.
An umbilical cord blood transplant (UCBT) involves using stem cells collected from a newborn’s umbilical cord and placenta after birth. These cells are frozen and stored in public or private cord blood banks until they are needed for a transplant.
Highly adaptable cells – Cord blood stem cells are immature, meaning they can adapt to the patient’s immune system more easily than adult stem cells.
Lower risk of GVHD – Since the immune system is less developed at birth, cord blood stem cells are less likely to attack the patient’s body.
No need for a perfect donor match – Unlike allogeneic transplants, cord blood transplants require only a partial match.
Commonly used for:
Children with leukemia, lymphoma, or genetic disorders
Patients without a matched sibling or unrelated donor
Limitations:
The cell dose is limited, meaning cord blood transplants may not be suitable for adults who need a higher number of stem cells.
The engraftment period is longer, increasing the risk of infections.
The choice of transplant type depends on several factors, including:
Disease Type & Severity: Patients with aggressive leukemia may need an allogeneic transplant, while those with multiple myeloma often undergo an autologous transplant.
Donor Availability: If a fully matched donor is unavailable, a haploidentical or cord blood transplant may be used.
Age & Overall Health: Older or weaker patients may not tolerate an allogeneic transplant due to its intensity.
Risk of Graft-versus-Host Disease (GVHD): Patients at higher risk of GVHD may benefit from autologous or cord blood transplants.
Each type of bone marrow transplant has unique advantages and risks. At Health is Your Journey with WEGOVITA, we work with top BMT specialists in Germany to ensure the best possible match and treatment strategy for every patient.

A bone marrow transplant (BMT) is a life-saving procedure that provides long-term benefits for patients with blood cancers, bone marrow failure syndromes, and genetic disorders. It is often the only curative option for many diseases and has the potential to restore normal blood cell production and immune function.
BMT is the only potential cure for several life-threatening conditions, including:
Leukemia & Lymphoma – By replacing cancerous bone marrow with healthy donor stem cells, BMT can eliminate malignant cells and restore normal hematopoiesis (blood formation).
Aplastic Anemia and Bone Marrow Failure Syndromes – For patients whose bone marrow no longer produces blood cells, a transplant introduces healthy stem cells that restart blood production.
Inherited Blood Disorders (Sickle Cell Disease, Thalassemia, SCID) – In genetic conditions where blood cells are malformed or defective, BMT provides a fresh supply of properly functioning cells.
BMT has been proven to significantly increase survival rates, especially for patients with high-risk blood cancers or refractory diseases (those that do not respond to standard treatments).
Studies show that patients who receive an allogeneic transplant (from a donor) for acute leukemia have up to a 70% survival rate if performed during remission.
For patients with aplastic anemia, BMT can restore normal blood cell production and prevent life-threatening complications from severe anemia or infections.
Children with severe combined immunodeficiency (SCID) who receive an early bone marrow transplant have a greater than 90% chance of survival.
One of the most critical functions of BMT is immune system reconstitution, particularly in patients who:
Have undergone intensive chemotherapy or radiation, which destroys immune cells.
Suffer from genetic immune deficiencies such as SCID.
Require an allogeneic transplant, which provides a completely new immune system from the donor.
BMT plays a crucial role in high-dose chemotherapy regimens used to treat aggressive cancers. Since chemotherapy and radiation damage bone marrow, doctors often recommend a transplant to:
Allow the use of stronger chemotherapy drugs – BMT enables higher-dose chemotherapy, which is more effective at destroying cancer cells.
Prevent prolonged bone marrow suppression – After chemotherapy, new donor stem cells help the body recover blood cell production more quickly.
Reduce the risk of relapse – For certain cancers like acute leukemia, BMT helps eliminate any remaining malignant cells that could cause a recurrence.
Expands Treatment Options for High-Risk Patients: Patients who have relapsed after multiple rounds of chemotherapy often have no other options besides BMT.
Eliminates the Need for Lifelong Blood Transfusions: Patients with severe thalassemia or aplastic anemia no longer require frequent transfusions post-transplant.
Graft-versus-Leukemia (GVL) Effect: In allogeneic transplants, the donor’s immune cells help destroy any remaining cancer cells, reducing relapse risk.
Faster Bone Marrow Recovery: Patients who receive transplants often recover full blood cell production within 3–6 months, improving overall health.

Bone marrow transplantation (BMT) has dramatically improved survival rates for patients with blood cancers, bone marrow failure syndromes, and genetic disorders. While outcomes depend on factors like disease type, patient age, donor match, and overall health, recent advances in transplantation techniques have led to higher success rates and long-term remission.
The 5-year survival rates for bone marrow transplant patients vary based on the disease being treated and the type of transplant performed. Below are survival statistics from major clinical studies and global transplant registries:
Autologous BMT: ~50–70% 5-year survival rate (used in specific cases for consolidation therapy).
Allogeneic BMT: ~50–75% 5-year survival rate (higher success when performed in remission).
Key Finding: Younger patients undergoing early transplantation during remission have a higher survival rate (above 70%).
Autologous BMT: ~60–80% 5-year survival rate.
Allogeneic BMT: ~45–65% 5-year survival rate (used in refractory or relapsed cases).
Key Finding: Patients with relapsed lymphoma responding to chemotherapy benefit the most from BMT.
Autologous BMT: ~50–75% 5-year survival rate.
Allogeneic BMT: ~35–50% 5-year survival rate (rarely performed due to risks).
Key Finding: Double autologous transplants (“tandem BMT”) improve survival in high-risk multiple myeloma.
Allogeneic BMT (Matched Sibling Donor): ~80–90% survival rate.
Allogeneic BMT (Unrelated Donor): ~65–80% survival rate.
Key Finding: Early transplants in younger patients have an excellent prognosis.
Allogeneic BMT (Matched Sibling Donor): ~85–95% survival rate.
Allogeneic BMT (Unrelated Donor): ~70–85% survival rate.
Key Finding: BMT is the only known cure for sickle cell disease, with excellent outcomes in children.
Children: ~60–85% survival rate.
Adults: ~50–70% survival rate.
Key Finding: Cord blood transplants have lower GVHD rates but slower engraftment.
Patient in remission at the time of transplant have higher survival rates.
Early-stage leukemia has better outcomes than high-risk or relapsed disease.
Matched sibling donors have the highest survival rates (70–90%).
Haploidentical & unrelated donor transplants carry higher risks of GVHD, but newer protocols are improving outcomes.
High-volume BMT centers in Germany report above-average survival rates due to advanced protocols, strict infection control, and cutting-edge therapies.
Patients monitored closely for infections, GVHD, and immune system recovery have improved long-term survival.
Lifestyle modifications, diet, and rehabilitation play a critical role in recovery.
Germany has some of the highest success rates in BMT, thanks to:
Bone marrow transplant (BMT) is primarily used for advanced or high-risk cases, but in some situations, it can be performed in earlier stages as a preventive or curative measure.
BMT is most commonly performed in patients with advanced, relapsed, or refractory blood cancers when:
Standard treatments (chemotherapy, radiation, or immunotherapy) fail.
The cancer is high-risk or aggressive, with a high chance of relapse.
The disease has returned after initial remission (relapsed disease).
Acute Leukemia (AML, ALL) – Advanced or relapsed cases.
Lymphoma – After multiple relapses or chemotherapy failure.
Multiple Myeloma – In high-risk or late-stage patients.
Severe Aplastic Anemia – When bone marrow stops producing blood cells.
In some cases, BMT is recommended at an early stage, particularly when:
The disease is genetic or inherited, and early intervention prevents complications.
The patient is at high risk of relapse, even if the disease is not yet advanced.
BMT is used as a curative treatment instead of lifelong therapy.
Sickle Cell Disease – BMT can be curative before severe organ damage occurs.
Thalassemia – Used in children before they become dependent on blood transfusions.
Myelodysplastic Syndromes (MDS) – In patients with high-risk mutations before it transforms into leukemia.
Clinical trials are exploring BMT as an earlier treatment for high-risk leukemia to prevent relapse rather than treat relapse.
Researchers are investigating whether early-stage multiple myeloma patients could benefit from BMT before the disease progresses.
Gene therapy + BMT combinations are being tested to make transplantation safer for younger patients with inherited blood disorders.
For blood cancers: BMT is mostly used in advanced, high-risk, or relapsed cases.
For genetic disorders: BMT can be curative when performed early.
For bone marrow failure syndromes: BMT is often needed as soon as possible.
