What is a bone marrow transplant (stem cell transplant)? (2023)

FAQs

What is stem cell or bone marrow transplants? ›

A bone marrow transplant is also called a stem cell transplant or, more specifically, a hematopoietic stem cell transplant. Transplantation can be used to treat certain types of cancer, such as leukemia, myeloma, and lymphoma, and other blood and immune system diseases that affect the bone marrow.

To prepare for a stem cell transplant, you receive chemotherapy to kill the diseased cells and malfunctioning bone marrow. Then, transplanted blood stem cells are put into your bloodstream. The transplanted stem cells find their way to your marrow, where — ideally — they begin producing new, healthy blood cells.

A procedure in which a patient receives healthy stem cells (blood-forming cells) to replace their own stem cells that have been destroyed by treatment with radiation or high doses of chemotherapy. The healthy stem cells may come from the bone marrow of the patient or from a related or unrelated donor.

A stem cell or bone marrow transplant replaces damaged blood cells with healthy ones. It can be used to treat conditions affecting the blood cells, such as leukaemia and lymphoma.

People have more probability of surviving for another 15 years after a bone marrow transplant, who's been able to survive for at least 5 years after hematopoietic cell transplant without any signs and symptoms of relapse of the original disease. However, a normal life expectancy is not completely achieved.

Bone marrow transplants treat cancers and other diseases of the blood and bone marrow by replacing unhealthy stem cells with healthy ones. BMT most commonly treats people with leukemia or lymphoma. BMT can be lifesaving for people whose bone marrow has been destroyed by chemotherapy or radiation treatment.

You might experience extreme fatigue, nausea or vomiting. Be patient — this should pass in a week or so. Remember that your body is busy trying to recover, and give it time to rest and heal. Pain: The high doses of chemotherapy used during conditioning may leave you with painful mouth sores and stomach irritation.

The stem cells will be passed slowly into your body through the central line. This process often takes around a couple of hours. The transplant will not be painful and you'll be awake throughout.

Study Population

Overall, the estimated survival of the study cohort was 80.4% (95% CI, 78.1% to 82.6%) at 20 years after transplantation. Survival beyond 5 years correlated inversely with age at transplantation (Fig 1).

Most diseases which may be defined as autoimmune disorders, such as multiple sclerosis, systemic lupus, chronic fatigue syndrome and fibromyalgia, will prevent you from donating marrow or blood-forming cells.

How serious is a bone marrow transplant? ›

A bone marrow transplant has serious risks. Some patients suffer from life-threatening problems as a result of their transplant. These problems can include serious infections and graft-versus-host disease (GVHD) , in which the transplanted cells attack the patient's body.

If you're between the ages of 18 and 40, committed to donating to any patient in need, and meet the medical guidelines, you can register to be a bone marrow donor. Patients especially need you if you're between the ages of 18 and 35. Research shows that cells from younger donors lead to more successful transplants.

Bacterial infections are the most common. Viral, fungal and other infections can also occur. Some infections can develop later on, weeks to months after the transplant. Infections can cause extended hospital stay, prevent or delay engraftment, cause organ damage, and may be life threatening.

A bone marrow transplant does not involve major surgery; rather, it's performed similarly to a blood transfusion. In a bone marrow transplant, bone marrow cells are collected from a donor's bloodstream through a needle inserted into a bone, typically a pelvic bone.

Infections, toxicity, and (after allogeneic HSCT only), graft-vs. -host disease (GVHD) are the main causes of death.

One of the reasons bone marrow transplants are often a last resort for patients with blood cancers is graft-versus-host disease (GVHD), a common occurrence where transplanted donor immune cells attack both malignant and healthy cells in the recipient.

The survival rates after transplant for patients with acute leukemia in remission are 55% to 68% with related donors and 26% to 50% if the donor is unrelated.

If you need to be in a hospital, you probably won't have to stay longer than 3 weeks. If the stem cells came from another person (allogeneic transplant), you may spend 4 weeks or longer in the hospital. About 1 out of 4 people need to be readmitted within the first 3 months because of problems that may occur.

The total costs of a stem cell transplant are typically $350,000-$800,000, depending on whether the procedure is autologous, meaning some of the patient's own marrow or stem cells are used, or allogeneic, meaning cells are harvested from a donor.

A brother or sister is most likely to be a match. There is a 1 in 4 chance of your cells matching. This is called a matched related donor (MRD) transplant. Anyone else in the family is unlikely to match.

How many hours does a bone marrow transplant take? ›

What happens during a bone marrow transplant? The entire transplant process takes around one to two hours. To receive your new bone marrow cells, healthy cells from your donor will be collected through an IV (intravenous) catheter (again, similar to donating blood) and transfused into you through a central line.

It can take a few weeks before donors completely recover from donating bone marrow. During your recovery, you may have the following side effects: Your lower back and the back of your hips may ache or feel sore for a few days after the procedure. You may have bruises.

You may be able to exercise as normal or stick with gentle activity such as light walking or cycling, and there are times when it's safest to avoid exercise. Your team will also be on the look-out for signs of infection, such as a fever.

The cost of a stem cell transplant can vary depending on the type of treatment needed, ranging from $15,000 to $75,000. According to a 2022 poll, treatments cost between $10,000 and $40,000, while a Twitter poll reported that patients could expect to spend from under $5,000 to over $50,000.

The recipient of a bone marrow transplant in 1963, Nancy King McLain is one of the world's longest living bone marrow transplant survivors. The physician who performed Nancy's transplant as his very first, Robert Kyle, MD, of Mayo Clinic, remains her doctor today.

Bone marrow transplantation has a long track record of success for treating certain cancers. While older age is no longer considered a barrier to receiving this treatment, making sure that it is right for you and that you're prepared for the transplant experience are vital parts of the decision-making process.

Leukemia or myelodysplastic syndrome (MDS) occasionally occurs in patients who were transplanted with their own stem cells (autologous transplant). The risk is highest among patients who: received certain types of chemotherapy before or during transplant, such as cytoxan or etoposide.

This is also called “failure to engraft” or “non-engraftment.” This is serious but uncommon. The most common treatment for graft failure is another transplant. A second transplant may use cells from the same donor or from a different donor.

You lose all your hair with ALL treatment. This includes your eyelashes, eyebrows, underarm, leg and sometimes pubic hair. Your hair will usually grow back once treatment has finished but it is likely to be softer. It may grow back a different colour or be curlier than before.

Who pays for bone marrow transplant? ›

All medical costs for the donation procedure are covered by the National Marrow Donor Program® (NMDP), which operates the Be The Match Registry®, or by the patient's medical insurance, as are travel expenses and other non-medical costs. The only costs to the donor might be time taken off from work.

For bone marrow transplantation, the blood group of the donor is not important. In fact, after bone marrow transplantation, the patient will have the donor's blood type.

For many patients, the donor search takes as little as 1-2 weeks from the time a donor testing request is made until the lab has the blood sample and HLA typing results. Sometimes it can take longer including some searches that may require multiple rounds of donor selections.

Medical guidelines for cellular therapy product donation (such as peripheral blood stem cells and bone marrow) include an assessment of body mass index (BMI), which is calculated from weight and height. There is not a minimum weight requirement.

A 2016 study of over 6,000 adults with AML found that people who received an autologous bone marrow transplant had a 5-year survival rate of 65%. For those who received an allogenic bone marrow transplant, it was 62%.

Research led by UAB's Institute for Cancer Outcomes and Survivorship and director Smita Bhatia, M.D., MPH (above) finds that patients who received autologous blood or marrow transplantation (using their own cells) over the past three decades lived on average seven years fewer than peers.

Stem cell or bone marrow transplants are treatments for some types of cancer including leukaemia, lymphoma and myeloma. You have them with high dose chemotherapy and sometimes radiotherapy. They are sometimes called stem cell rescue, or bone marrow rescue, or intensive treatment.

At Mayo Clinic, doctors will consider selected patients over 65 years of age, depending on their overall physical health. People who need a bone marrow transplant may have any of several serious conditions, including: Acute lymphocytic leukemia.

What is the cut off age for being an adult marrow donor? Everyone on Be The Match Registry is critical to saving lives. Once you become a registry member, you are listed on the registry until the age of 61, unless you request to be removed from the registry before then.

Why can't people over 40 donate bone marrow? ›

The upper age limit is based on both donor and patient considerations. There is a small increase in the risk of complications from donations in older donors. There is also a slightly increased risk of blood disorders in older people.

A stem cell transplant uses stem cells from your bloodstream, or a donor's bloodstream. This is also called a peripheral blood stem cell transplant. A bone marrow transplant uses stem cells from your bone marrow, or a donor's bone marrow.

Avoid any forceful rotation or manual manipulation. Remember that good healing during the first two months after the procedure will give you the best chance for success. The cells are fragile, and you need to be cautious that you don't overload them or cause too much stress or shearing on them.

UChicago Medicine had an 80% one-year survival rate among adult stem cell patients, according to the latest statistics released in mid-December by the Center for International Blood & Marrow Transplant Research (CIBMTR) on behalf of the U.S. Health Resources & Services Administration (HRSA).

People who might benefit from stem cell therapies include those with spinal cord injuries, type 1 diabetes, Parkinson's disease, amyotrophic lateral sclerosis, Alzheimer's disease, heart disease, stroke, burns, cancer and osteoarthritis.

The stem cells will be passed slowly into your body through the central line. This process often takes around a couple of hours. The transplant will not be painful and you'll be awake throughout.

One of the reasons bone marrow transplants are often a last resort for patients with blood cancers is graft-versus-host disease (GVHD), a common occurrence where transplanted donor immune cells attack both malignant and healthy cells in the recipient.

One factor is the age of the donor. Medical research has shown that cells from younger donors lead to better long-term survival for patients after transplant. Doctors request donors in the 18-35 age group 75% of the time. We are committed to providing the best possible outcome for patients.

What are the negatives of using stem cells? ›

Common short-term side effects of stem cell therapy include fatigue, headache, chills, nausea, and low-grade fever. However, side effects vary; not every patient will experience side effects. These side effects are generally mild and temporary.

Our current knowledge of human stem cells makes it feasible to delay aging and improve health and lifespan. Stem cell treatments can play a crucial role in delaying the aging process. Together with anti-aging genes, a stem cell infusion can create a sophisticated shield that can prevent or slow the effects of aging.
