A bone marrow transplant is a medical operation to replace damaging bone marrow stem cells with damaged or unhealthy bone marrow. The bone marrow creates red, white, and platelet-producing blood cells. A bone marrow transplant may be required to re-establish the body’s capacity to create healthy blood cells when conditions like leukemia, lymphoma, or specific genetic disorders damage the bone marrow.
High doses of chemotherapy or radiation treatment are administered to the patient during a bone marrow transplant in order to eradicate the diseased bone marrow. It may be a life-saving treatment for people with certain cancers and genetic disorders. However, it is a difficult and dangerous operation that needs to be carefully assessed and managed by a group of medical experts. Here, we will give you a comprehensive guide about the transplant, procedure, and potential risks.
What is a Bone Marrow Transplant?
A hematopoietic stem cell transplant or bone marrow transplant is a medical operation used to replace unhealthy bone marrow stem cells with damaged or diseased bone marrow. Bone marrow transplants can be performed in a variety of ways, including autologous (using the patient’s own stem cells), heterologous (using a donor’s stem cells), and umbilical cord blood (using stem cells extracted from a newborn’s umbilical cord).
The healthcare team will decide which transplant type is best for each patient because each variety has advantages and risks. A team of medical experts must carefully assess and manage the risky and complex bone marrow transplant process. It may be a life-saving treatment for those with specific cancers and genetic disorders.
Types of Bone Marrow Transplant
Autologous, allogeneic, and umbilical cord blood transplants are the three primary types of bone marrow transplantation which include –
- When a patient undergoes an autologous transplant, their own stem cells, which were previously gathered and stored, are given to the patient.
- When a patient gets stem cells through an allogeneic transplant, the donor can be a close relative or an unrelated third party.
- When stem cells are removed from an infant baby’s umbilical cord and placenta, an umbilical cord blood transplant is performed.
Preparing for a Bone Marrow Transplant
A bone marrow transplant requires careful planning and a number of steps to guarantee the best results for the patient. The healthcare team will collaborate closely with the patient to create a custom therapy plan and will offer guidance and support during the planning stage.
Before the transplant, the patient will undergo a thorough evaluation that includes physical exams, blood tests, and imaging tests to decide the best type of transplant for them. A transplant team, including hematologists, oncologists, nurses, social workers, and other specialists, will also visit with the patient to review the procedure’s potential risks and rewards.
The Bone Marrow Transplant Procedure
Stem cell collection, conditioning therapy, and the actual transplant are just a few stages in the bone marrow transplant process.
- Before getting stem cells from a compatible donor or harvesting their own, the patient will first undergo stem cell collection. Depending on the donation type, stem cells can be extracted from the bone marrow, umbilical cord, or blood.
- The patient will undergo conditioning treatment, which involves high-dose chemotherapy and/or radiation therapy to eradicate the diseased bone marrow and suppress the immune system, enabling the new stem cells to engraft and generate healthy blood cells.
- The patient will receive a stem cell transplant after the conditioning treatment, which is similar to a blood transfusion.
- Engraftment is the process by which the new stem cells move to the bone marrow and start to generate new blood cells.
Potential Risks and Complications
The short-term adverse effects of a bone marrow donation may include fatigue, hair loss, mouth sores, fever, chills, nausea, vomiting, and diarrhea. These side effects are usually temporary and can be controlled with medication and supportive treatment.
Infertility, secondary cancers, and organ damage, including damage to the lungs, liver, and kidneys, are possible long-term adverse effects of bone marrow transplants. The sort of transplant, the conditioning therapy, and the patient’s general health all affect the danger and severity of these side effects.
Serious medical conditions that can occur after bone marrow transplant include graft-versus-host disease, a condition in which the new stem cells attack the patient’s body, which can be life-threatening for patients with weakened immune systems, and veno-occlusive disease, a condition in which the blood vessels in the liver become damaged.
Bone Marrow Transplant Cost in India
Bone marrow transplant Cost in India varies depending on the type of transplant, the patient’s health, the hospital and location where the treatment is given, the duration of hospitalization, and the post-transplant care necessary. Many things are involved in the transplant, including stem cell collection and processing, conditioning regimen, transplantation procedure, hospitalization and post-transplant care, medication, follow-up, monitoring, and stem cell collection and processing. In India, it costs between Rs 5 to 10 lakhs, according to the patient’s medical condition.
Research and Advancements in Bone Marrow Transplant Technology
The technology behind bone marrow transplants has advanced considerably over time, improving patient outcomes and increasing the range of available treatments. Research developments have produced several fresh and creative methods for bone marrow transplantation, including the following –
Haploidentical transplant: This procedure includes using stem cells from a donor who only partially matches the patient. This can increase the number of potential donors and shorten the time patients must wait for a donor.
Reduced-intensity conditioning: This method makes bone marrow transplantation more accessible for older patients and those with underlying medical problems by using lower chemotherapy and radiation treatment doses.
Gene therapy: It is a cutting-edge method that involves altering the patient’s stem cells to fix genetic abnormalities before transplant, possibly curing genetic diseases and lowering the risk of complications from the transplant.
These improvements in bone marrow transplant technology have increased the range of treatment choices available to patients with various diseases and improved the procedure’s overall success rate. Even though a bone marrow transplant may be a life-saving therapy for some conditions, it is crucial for patients to carefully consider their options, assess the risks and benefits of the procedure, and weigh the benefits against the risks.
