StemCell Therapy

There are several steps in the transplant process. The steps are much the same, no matter what type of transplant youre going to have.

You will first be evaluated to find out if you are eligible for a transplant. A transplant is very hard on your body. For many people, transplants can mean a cure, but for some people, problems can lead to severe complications or even death. Youll want to weigh the pros and cons before you start.

Transplants can also be hard emotionally. They often require being in the hospital, being isolated, and theres a high risk of side effects. Many of the effects are short-term, but some problems can go on for years. This can mean changes in the way you live your life. For some people its just for a while, but for others, the changes may be lifelong.

Before you have a transplant, you need to discuss the transplant process and all its effects with your doctors. It also helps to talk to others who have already had transplants.

Its also very hard going through weeks and months of not knowing how your transplant will turn out. This takes a lot of time and emotional energy from the patient, caregivers, and loved ones. Its very important to have the support of those close to you. For example, youll need a responsible adult who will be with you to give you medicines, help watch for problems, and stay in touch with your transplant team after you go home. Your transplant team will help you and your caregiver learn what you need to know. The team can also help you and your loved ones work through the ups and downs as you prepare for and go through the transplant.

Many different medical tests will be done, and questions will be asked to try to find out how well you can handle the transplant process. These might include:

You will also talk about your health insurance coverage and related costs that you might have to pay.

You may have a central venous catheter (CVC) put into a large vein in your chest. This is most often done as outpatient surgery, and usually only local anesthesia is needed (the place where the catheter goes in is made numb). Nurses will use the catheter to draw blood and give you medicines.

If youre getting an autologous transplant, a special catheter can be placed that can also be used for apheresis to harvest your stem cells.

The CVC will stay in during your treatment and for some time afterward, usually until your transplanted stem cells have engrafted and your blood counts are on a steady climb to normal.

Younger people, those who are in the early stages of disease, or those who have not already had a lot of treatment, often do better with transplants. Some transplant centers set age limits. For instance, they may not allow regular allogeneic transplants for people over 50 or autologous transplants for people over 65. Some people also may not be eligible for transplant if they have other major health problems, such as serious heart, lung, liver, or kidney disease. A mini-transplant, described under Allogeneic stem cell transplant in Types of Stem Cell Transplants for Cancer Treatment may be an option for some of these people.

The hospitals transplant team will decide if you need to be in the hospital to have your transplant, if it will be done in an outpatient center, or if you will be in the hospital just for parts of it. If you have to be in the hospital, you will probably go in the day before the transplant procedure is scheduled to start. Before conditioning treatment begins (see section below), the transplant team makes sure you and your family understand the process and want to go forward with it.

If you will be having all or part of your transplant as an outpatient, youll need to be very near the transplant center during the early stages. Youll need a family member or loved one as a caregiver who can stay with you all the time. You and the caregiver will also need reliable transportation to and from the clinic. The transplant team will be watching you closely for complications, so expect to be at the clinic every day for a few weeks. You may still need to be in the hospital if your situation changes or if you start having complications.

To reduce the chance of infection during treatment, patients who are in the hospital are put in private rooms that have special air filters. The room may also have a protective barrier to separate it from other rooms and hallways. Some have an air pressure system that makes sure no unclean outside air gets into the room. If youre going to be treated as an outpatient, you will get instructions on avoiding infection.

The transplant experience can be overwhelming. Your transplant team will be there to help you physically and emotionally prepare for the process and discuss your needs. Every effort will be made to answer questions so you and your family fully understand what will be happening to you as you go through transplant.

Its important for you and your family to know what to expect, because once conditioning treatment begins (see the next section), theres no going back there can be serious problems if treatment is stopped at any time during transplant.

Conditioning, also known as bone marrow preparation or myeloablation, is treatment with high-dose chemo and/or radiation therapy. Its the first step in the transplant process and typically takes a week or two. Its done for one or more of these reasons:

The conditioning treatment is different for every transplant. Your treatment will be planned based on the type of cancer you have, the type of transplant, and any chemo or radiation therapy youve had in the past.

If chemo is part of your treatment plan, it will be given in your central venous catheter and/or as pills. If radiation therapy is planned, its given to the entire body (called total body irradiation or TBI). 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. A very common problem is mouth sores that will need to be treated with strong pain medicines. You may also have nausea, vomiting, be unable to eat, lose your hair, and have lung or breathing problems.

Conditioning can also cause premature menopause in women and often makes both men and women sterile (unable to have children). (See Stem cell transplant and having children in Stem Cell Transplant Side Effects.)

After the conditioning treatment, youll be given a couple of days to rest before getting the stem cells. They will be given through your central venous catheter, much like a blood transfusion. If the stem cells were frozen, you might get some drugs before the stem cells are given. 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. 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 theyre not frozen. The length of time it takes to get all the stem cells depends on how much fluid the stem cells are in.

You will be awake for this process, and it doesnt hurt. This is a big step and often has great meaning for recipients and their families. Many people consider this their rebirth or chance at a second life. They may celebrate this day as they would their actual birthday.

Side effects from the infusion are rare and usually mild. The preserving agent used when freezing the stem cells (called dimethylsulfoxide or DMSO) causes many of the side effects. For instance, you might have a strong taste of garlic or creamed corn in your mouth. Sucking on candy or sipping flavored drinks during and after the infusion can help with the taste. Your body will also smell like this. The smell may bother those around you, but you might not even notice it. The smell, along with the taste, may last for a few days, but slowly fades away. Often having cut up oranges in the room will offset the odor. Patients who have transplants from cells that were not frozen do not have this problem because the cells are not mixed with the preserving agent.

Other side effects you might have during and right after the stem cell infusion include:

Again, side effects are rare and usually mild. If they do happen, they are treated as needed. The stem cell infusion must always be completed.

The recovery stage begins after the stem cell infusion. During this time, you and your family wait for the cells to engraft, or take, after which they start to multiply and make new blood cells. The time it takes to start seeing a steady return to normal blood counts varies depending on the patient and the transplant type, but its usually about 2 to 6 weeks. Youll be in the hospital or visit the transplant center daily for at least a few weeks.

During the first couple of weeks youll have low numbers of red and white blood cells and platelets. Right after transplant, when your counts are the lowest, you may be given antibiotics to help keep you from getting infections. (This is called prophylactic antibiotics.) You may get a combination of anti-bacterial, anti-fungal, and anti-viral drugs. These are usually given until your white blood cell count reaches a certain level. Still, you can have problems, such as infection from too few white blood cells (neutropenia), or bleeding from too few platelets (thrombocytopenia). Many patients have high fevers and need IV antibiotics to treat serious infections. Transfusions of red blood cells and platelets are often needed until the bone marrow starts working and new blood cells are being made by the infused stem cells.

Except for graft-versus-host disease, which only happens with allogeneic transplants, the side effects from autologous, allogeneic, and syngeneic stem cell transplants are much the same. Problems may include stomach, heart, lung, liver, or kidney problems. (Stem Cell Transplant Side Effects goes into the details.) You might also go through feelings of distress, anxiety, depression, joy, or anger. Adjusting emotionally after the stem cells can be hard because of the length of time you feel ill and isolated from others.

You might feel as if you are on an emotional roller coaster during this time. Support and encouragement from family, friends, and the transplant team are very important to get you through the challenges after transplant.

The discharge process actually begins weeks before your transplant. It starts with the transplant team teaching you and your primary (main) caregiver about:

For the most part, transplant centers dont send patients home until they meet the following criteria (Why Are Stem Cell Transplants Used as Cancer Treatment? has more information about neutrophils, platelets, and hematocrit):

If you do not meet all of these requirements, but still dont need the intensive care of the transplant unit, you might be moved to another oncology unit. When you do go home, you might need to stay near the transplant center for some time, depending on your condition.

The process of stem cell transplant doesnt end when you go home. Youll feel tired, and some people have physical or mental health problems in the rehabilitation period. You might still be taking a lot of medicines. These ongoing needs must now be managed at home, so caregiver and friend/family support is very important.

Transplant patients are still followed closely during rehab. You might need daily or weekly exams along with things like blood tests, and maybe other tests, too. During early rehab, you also might need blood and platelet transfusions, antibiotics, or other treatments. At first youll need to see your transplant team often, maybe even every day, but youll progress to less frequent visits if things are going well. It can take 6 to 12 months, or even longer, for blood counts to get close to normal and your immune system to work well. During this time, your team will still be closely watching you.

Some problems might show up as much as a year or more after the stem cells were infused. They can include:

Other problems can also come up, such as:

Your transplant team is still there to help you. Its important that you talk to them about any problems you are having they can help you get the support you need to manage the changes that you are going through. They can also help you know if problems are serious, or a normal part of recovery. The National Bone Marrow Transplant Link helps patients, caregivers, and families by providing information and support services before, during, and after transplant.
