Introduction to Bone Marrow Transplant and Cancer Care in Bangalore
A bone marrow transplant in Bangalore is a life-saving procedure in which damaged or diseased bone marrow is replaced by healthy stem cells. Bone marrow, located inside bones, produces red blood cells, white blood cells, and platelets, which are essential for carrying oxygen, supporting immunity, and facilitating blood clotting. When the stem cells are damaged by a disease or intensive cancer treatment, a stem cell transplant in Bangalore can help restore healthy blood cell production and immune function.
Bone marrow transplant is performed to treat several malignant and non-malignant conditions. It is an important part of treating blood cancers, particularly leukaemia, lymphoma and multiple myeloma. At Cancer Therapy India, the BMT specialist in Bangalore perform a detailed analysis of each patient and chooses the most appropriate treatment plan.
Types of Bone Marrow Transplant
These are the types of Hematopoietic stem cell transplants, depending on the source of healthy stem cells and the donor match.
- Autologous Transplant
An autologous transplant involves the transplant of the patient’s own stem cells. Cells are gathered and frozen before high doses of chemotherapy or radiation. The cells are then returned to the body to restore healthy blood cell production. This approach avoids graft rejection because the patient’s own stem cells are used and is used for several types of relapsed lymphomas and multiple myeloma.
- Allogeneic Transplant
An allogeneic transplant involves utilising stem cells from a healthy donor who has a very similar Human Leukocyte Antigen (HLA) profile. Donors are often siblings, but can be unrelated matched donors. A key benefit is the graft-versus-tumour effect, in which donor immune cells help destroy residual cancer cells.
- Haploidentical Transplant
A haploidentical transplant involves stem cells from a partially matched donor, typically a parent, child or sibling. With better cell-processing techniques and modern immunosuppressive medications, this is now safer and more widely available.
- Umbilical Cord Blood Transplant
This transplant involves using stem cells from the placenta and umbilical cord after a baby’s birth. These cells are less immunologically mature and do not require as close an HLA match as other donor sources; they are useful in patients with rare tissue types.
How Bone Marrow Transplant is Performed
Bone Marrow Transplantation is a carefully planned, sequential process designed to support successful stem cell engraftment and recovery.
- Collection of Stem Cells: This is where healthy stem cells are removed from the donor’s bone marrow, or collected from the donor’s peripheral blood by using a special filtering machine.
- The Conditioning Phase: Here, the patient will undergo high-dose chemotherapy, radiation, or sometimes, a combination of both. This phase of stem cell transplantation is needed to remove remaining cancerous cells and suppress the existing immune system to prevent rejection of the new cells.
- Infusion of Stem Cells: On the day of the transplant, the healthy stem cells are infused into the patient’s bloodstream via a central venous IV line in a systematic way after the conditioning phase. It is the same procedure as a blood transfusion and does not require surgery.
- The Engraftment Process: Circulating throughout the body, the transplanted cells naturally migrate to the bone marrow spaces. This is when engraftment takes place, and the new stem cells settle and begin actively generating fully functional, normal blood cells.
Bone Marrow Transplant Categories / Sources
Transplants are classified not only by the person providing the cells but also by the part of the body from which stem cells are collected. The recovery rate and logistical planning are significantly influenced by the choice of source.
- Peripheral Blood Stem Cell Transplant (PBSC): This represents the most common method of collection. The donor or patient receives daily injections of growth factors given to move stem cells from the bone marrow into the bloodstream. Through a non-surgical, outpatient process, these cells are filtered from the blood by a specialised machine called an apheresis machine.
- Bone Marrow Harvest: This is the more traditional method, which involves a surgical procedure under general anaesthesia. A specialist collects marrow from the pelvic bone using specialised needles. It is very useful for some paediatric conditions and for cases of aplastic anaemia, and is a short surgical procedure for the donor.
- Cord Blood Transplant: This is a very specialised form that involves using cells from cord blood units. While they have fewer stem cells overall, their adaptability makes them valuable for patients who do not have a matching adult donor.
Diseases Treated with Bone Marrow Transplant
Bone marrow transplant treatment in Bangalore is a therapeutic approach that can be used when the natural marrow becomes severely damaged or fails to function properly. Stem cell therapy is used for cancers and very severe genetic and haematological diseases.
Malignant Conditions
- Leukaemia: A serious form of blood cancer in which abnormal white blood cells grow rapidly. A blood transplant is often the first choice for long-term remission or a complete cure.
- Lymphoma: Cancers that develop in the lymphatic system, including those that are resistant to traditional front-line chemotherapy.
- Multiple Myeloma: It is a form of plasma cell malignancy, in which high doses of chemotherapy followed by an autologous transplant are a standard treatment approach.
Non-Malignant Conditions
- Aplastic Anaemia: A severe form of anaemia in which the bone marrow will no longer generate all three blood types, resulting in life-threatening deficiencies.
- Thalassemia and Other Blood Disorders: Inherited genetic blood disorders which lead to abnormal production of haemoglobin and require a total replacement of the haemopoietic system.
- Immune Deficiency Disorders: Congenital disorders in which children are born without a functioning immune system and therefore are completely vulnerable to common infections.
- Bone Marrow Failure Syndromes: A wide range of rare diseases in which the marrow is no longer able to produce healthy cells over time.
Bone Marrow Transplant Process
There are a number of stages involved in bone marrow transplantation; these can be divided into phases that require strict monitoring and control.
Phase 1: Pre-Transplant Evaluation and Tests
The process starts with a detailed assessment, which may include blood tests, imaging scans and cardiac and lung function tests, to determine that it is safe to administer the high-dose treatment. Psychological assessment and dietary counselling may also be undertaken.
Phase 2: Donor Matching and Stem Cell Collection
In allogeneic transplantation, the doctors will perform HLA typing to find a suitable matched donor, and the stem cells will be collected via apheresis or from bone marrow. For autologous transplant patients, their stem cells are collected and then stored before treatment.
Phase 3: Conditioning Therapy
The patient undergoes chemotherapy or total body irradiation within dedicated transplant units. The purpose of this is to destroy any residual cancer cells and prepare the bone marrow to receive the subsequent stem cell transplant.
Phase 4: Transplant Day (Stem Cell Infusion)
The stem cells are then transferred into the patient via a central venous catheter. The medical team closely monitors the patient for any immediate reactions during the procedure.
Phase 5: Engraftment and Recovery Phase
Once infused into the patient, the stem cells travel to the bone marrow & begin producing new healthy blood cells. Blood counts are extremely low, and they are more prone to infection at this time. When blood cell counts steadily rise, engraftment is confirmed.
Phase 6: Monitoring and Supportive Care
Patients are monitored constantly and given antibiotics, antifungals, blood transfusions, and nutritional and infection-control treatments until they have recovered.
Outcomes and Effectiveness of Bone Marrow Transplant
The success of a bone marrow transplant often depends on several clinical factors, but it offers many benefits over conventional treatments.
- Restoration of Healthy Blood Cell Production: The first structural step in restoration is to restore healthy blood cell production.
- Potential Cure for Certain Blood Cancers: In clinical practice, a transplant may offer the best chance of long-term remission or cure for certain blood cancers (such as some forms of aggressive leukaemia), including acute leukaemias.
- Improved Immune System Function: After the treatment is finished, the immune system is functioning properly, and the patient is protected against common, naturally occurring infections and illnesses.
- Long-Term Disease Control: For chronic or hard-to-treat conditions, it effectively halts disease progression, improving patients’ long-term quality of life.
The long-term outcome of the procedure depends largely on the accuracy of the donor match, the type and severity of the underlying disease, and the patient’s physical health before conditioning.
Risks and Side Effects of Bone Marrow Transplant
Bone marrow transplant is an intensive medical treatment with significant risks and potential side effects.
- Infection Risk Due to Low Immunity: This conditioning phase leaves the patient very susceptible to bacterial, viral and fungal infections during the weeks before engraftment.
- Graft-Versus-Host Disease (GVHD): Exclusive to allogeneic transplants, GVHD arises when the newly infused donor immune cells recognise the patient’s organs as foreign entities. This immune response can cause inflammation and damage to the skin, liver, and gastrointestinal tract, requiring management with immunosuppressive drugs.
- Systemic Side Effects: Patients undergoing intensive treatment may experience side effects such as extreme fatigue, severe nausea and vomiting, mouth sores (mucositis), and overall physical weakness.
- Organ-Related Complications: Sometimes, high doses of therapeutic drugs can cause temporary or permanent problems with important organs, such as the liver, kidneys or lungs.
- Long Recovery Period and Monitoring: Recovery after transplant requires close monitoring and long-term follow-up, with patients needing to be monitored closely in the hospital, and treatment plans adjusted accordingly.
Bone Marrow Transplant Recovery and Duration
Recovery following a transplant is slow, gradual, and requires a great deal of patience from the patient and their surroundings.
The first recovery period lasts around 2 to 4 weeks, which correlates directly with the time required for the new stem cells to engraft and be detected in peripheral blood counts. The first hospitalisation can range in length from one patient to another, depending on how the patient responds to treatment, such as if they become very ill with an infection or acute GVHD.
After discharge from the hospital, the immune recovery stage begins. With autologous recipients, it takes several months to achieve full, robust immune protection, and 1 to 2 years with allogeneic recipients. During all of this, frequent follow-up visits and strict clinical management are essential to evaluate graft function, monitor organ function and manage possible late-onset side effects.
