Before a transplant, stem cells can be collected from a person’s bone marrow
Bone marrow
Bone marrow is a semi-solid tissue which may be found within the spongy or cancellous portions of bones. In birds and mammals, bone marrow is the primary site of new blood cell production or hematopoiesis. It is composed of hematopoietic cells, marrow adipose tissue, and supportive stromal cells. In adult humans, bone marrow is primarily located in the ribs, vertebrae, sternum, and bone…

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.
How do I prepare for stem cell donation?
Donors need to keep their schedules light about a week before the stem cell donation process. As mentioned, the donor will receive shots for several days before the donation. These shots promote the production of stem cells. The donor may also set aside at least a day or two to recover.
Do you have to have chemo before stem cell transplant?

TBI may be given in a single treatment session or in divided doses over a few days. This phase of the transplant can be very uncomfortable because very high treatment doses are used. Chemo and radiation side effects can make you sick, and it may take you months to fully recover.
How many bags of stem cells are there?
There may be more than 1 bag of stem cells. For allogeneic or syngeneic transplants, the donor cells may be harvested (removed) in an operating room, and then processed in the lab right away. Once they are ready, the cells are brought in and given to you – they’re not frozen.
What happens if you freeze stem cells?
These drugs are used to help reduce your risk of reacting to the preservatives that are used when freezing the cells. If the stem cells were frozen, they are thawed in warm water then given right away.
What is the purpose of bone marrow conditioning?
To make room in the bone marrow for the transplanted stem cells. To suppress the patient’s immune system to lessen the chance of graft rejection. To destroy any remaining cancer cells in the patient’s body. The conditioning treatment is different for every transplant.
Diet
There is no special diet preparation before a stem cell transplant. You do not have to take a lot of vitamins. If you are under- or overweight, try to get to your normal weight before you come into the hospital. Your doctor can guide you with this effort.
Preserving Fertility
Many cancer treatments can affect fertility, the ability to have children. You may be infertile from the treatment you have already received. If not, you will most likely be infertile after your transplant treatment. This will have no effect on your ability to have sex. However, some patients report that they have a decrease in their sex drive.
Radiation Simulation
If you are going to have radiation as part of your treatment, you will meet with the radiation therapy team before you are admitted. You may also have a CT scan or PET scan or both to plan your treatment. You will also have a planning session called simulation. During this session, several x-rays are taken along with measurements of your chest.
Dental Exam
You will have a dental exam. Decayed teeth and gums can cause serious infections in patients being treated with high doses of chemo or radiation. We must be sure that anything that could cause an infection in your mouth is fixed before your transplant. For example, you may need cavities filled, loose fillings replaced, or gum disease treated.
Tests
Before your treatment starts, you will have some tests done. These will tell us how your body is functioning and what the status of your cancer or bone marrow disease is. We will use the test results to watch for any changes during treatment. You will have some, or possibly all of the following tests::

Why do patients stay in the hospital?
Most patients stay in the hospital during this period to be protected from infection and monitored for side effects , though select patients may be candidates for outpatient stem cell transplant.
Does a donor feel pain after a transplant?
The donor may feel some pain after this procedure. Conditioning treatment — administration of chemotherapy and/or radiation to the patient in order to destroy all of the diseased cells in the body and to create space in the bone marrow for the transplanted stem cells to populate.
How long does it take for a stem cell transplant to grow?
There they will grow and develop into new mature blood cells, including red and white blood cells and platelets. It usually takes several weeks before the level of mature blood cells returns to a healthy number.
How are stem cells added to the bloodstream?
Next, the stem cells are added your bloodstream through a central venous catheter (a flexible tube). This tube goes into your chest and makes it easier for your care team to give you medications and blood products. The transplant is done in your room. It is like having a blood transfusion. No surgery is required.
What are stem cells?
Blood-forming stem cells are also called bone marrow cells or hematopoietic stem cells. They are immature cells that can become any type of blood cell, including: 1 white blood cells, which help the body fight infections 2 red blood cells, which carry oxygen throughout the body 3 platelets, which are important in blood clotting and help control bleeding

Can you get chemo without radiation?
For this type of transplant, you get higher doses of chemo (with or without radiation) than you would get if you weren’t getting a transplant. The higher doses may cause more severe side effects, but they also destroy more diseased cells.
What is stem cell transplant?
Stem cell transplants help restore blood-forming stem cells in people who have had theirs destroyed by certain cancer treatments. Results from a large phase III clinical trial suggest that a highly intensive preparatory, or conditioning, regimen should be used for younger patients with acute myeloid leukemia (AML) or myelodysplastic syndromes (MDS) ...
Do stem cell transplants relapse?
Patients in the trial who received this standard "myeloablative" conditioning regimen, which entails high doses of chemotherapy and/or radiation, were far less likely to experience a disease relapse after the stem cell transplant than patients who received less aggressive, or reduced-intensity, conditioning regimens.
How is bone marrow recovered from chemotherapy?
The cells are then returned to the patient via an infusion into the bloodstream (like a blood transfusion) to rescue the bone marrow from the effects of the high doses of chemotherapy. This procedure is associated with good response rates and remains the standard of care, after completion of primary therapy, for eligible patients.
What is the difference between autologous and allogeneic transplant?
The main difference between autologous and allogeneic transplant is that in allogeneic transplant, the cells are obtained from a donor whose cells are compatible with those of the patient, usually a brother or sister. Side effects and mortality are more likely to occur with an allogeneic transplant than with an autologous transplant.
What tests are used to monitor myeloma?
Response to the transplant is measured by the standard tests used to monitor myeloma treatment, such as blood and urine protein levels, marrow tests and imaging studies. Myeloma patients who have had an autologous transplant may require maintenance therapy (see below). Tandem Autologous Stem Cell Transplantation.
Is Revlimid a maintenance therapy?
Lenalidomi de (Revlimid®) is the preferred agent for post-transplant maintenance, based on the results of several clinical trials. Lenalidomide is FDA approved for patients with myeloma as maintenance therapy following an autologous stem cell transplant. It does not produce the neurotoxicity of other immunomodulatory drugs. However, there appears to be an increased risk for the development of a secondary cancer, especially after transplantation or after therapy with a regimen that contains melphalan. More information is needed about the effects of maintenance therapy on overall survival, as well as second cancer risk. Maintenance therapy with bortezomib (Velcade®) or ixazomib (Ninlaro®) is recommended for patients with certain cytogenetic abnormalities.

This procedure is associated with good response rates and remains the standard of care, after completion of primary therapy, for eligible patients. However, it is not appropriate for all patients, and it is not a cure for myeloma. Patients should discuss the benefits and risks of any procedure with their doctors.
Is an allogeneic transplant more likely to cause side effects?
Side effects and mortality are more likely to occur with an allogeneic transplant than with an autologous transplant. Therefore, allogeneic transplantation has a limited role in myeloma treatment and it should only be done in the context of a clinical trial.
