The body's immune system can attack the donor stem cells. This is called rejection. The transplanted cells can attack the body's cells. This is called graft-versus-host disease.
Graft failure happens when the new cells don't make the new white blood cells, red blood cells, and platelets you need. 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.
To start, they are your own alive and healthy cells. Also, they are harvested directly from your body and used the same day. The best part about using a patient's own stem cells is that there is no possibility of the body rejecting these cells. Either they work, or they don't.
Graft failure, a rare complication, happens when your immune system rejects the donor's stem cells. If more donor stem cells are available, it can be treated with a second transplant, or with an infusion of residual lymphocytes -- a type of white blood cell -- from the donor.
Despite your best efforts and the support of your medical team, family and friends, your stem cell transplant might not work. This could be because your donor's cells haven't been accepted by your body, that your original condition has come back or other complications such as Graft vs Host Disease (GvHD).
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).
These can include changes in physical appearance (such as hair loss or changes to the skin) and changes to the body's function (such as fertility or mobility). All of these changes can have a negative impact on the affected person's body image.
You will feel very tired and run down after your transplant. This will be at its worst during the second and third weeks when your blood cell counts are at their lowest.
Day 100 is a milestone that many stem cell transplant recipients circle boldly on their calendars as the turning point in their recovery. That's when the greatest risk for critical side effects is past and when the stem cells have engrafted and begun making new blood cells.
Failure rate for peripheral blood stem cell harvest, 3.6%. Toxic death rate included patients undergoing autologous stem cell transplant. Eighty-seven percent of patients had adequate CD34+ cell collection with a median of one apheresis procedure.
It's common to feel sick and be sick after your transplant because of your treatment, medication, a possible infection or GvHD. Nausea normally only lasts a week or two for most people. If you struggle with nausea for longer, talk to your transplant team because they might need to change your medication.
For some people, fatigue is a short-term effect of treatment that gets better over a few months. Or it might come and go for about six months to a year. Others might recover many years after their transplant, or it may never completely go away.
Relapse of the original malignancy after SCT now remains the most frequent cause of treatment failure and mortality. Approximately 40–45% of recipients of HLA-identical siblings and approximately 35% of recipients of unrelated donor transplants will relapse with their original malignancy (Figure 1) [1].
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.
“Relapse after allogeneic HSCT occurs in up to 30% of patients with Ph+ ALL and long-term OS has been dismal,” he said. “In other hematologic malignancies, therapeutic advances resulted in significant improvement over time in survival of patients who relapsed after transplant.”
Foods to avoid (unsafe):
Cold meat or poultry. Raw eggs. Eggs not well-cooked such as sunny-side-up (runny yolk) Cold soups and gazpacho, all miso products such as paste and soup.
Stem cell or bone marrow transplants are complex treatments that carry a significant risk of serious complications. It's important that you're aware of both the risks and possible benefits before treatment begins. You may wish to discuss them with your treatment team and your family.
55.6% of patients experienced a significant weight loss of ≥5% with a median decrease of 9.2% in BMI.
When the new stem cells multiply, they make more blood cells. Then your blood counts will go back up. This is one way to know if a transplant was a success. Your cancer is controlled.
More than 80% of people who had aplastic anemia are cured after allogeneic stem cell transplantation. More than half of all people who received allogeneic stem cell transplantations for acute leukemia in remission are cured.
Here is information on three-year survival rates: Multiple myeloma: Data show 79% were alive three years after transplant. Hodgkin lymphoma: Studies show most people receive HSCT to treat Hodgkin lymphoma that came back after chemotherapy. Of those, 92% of those people were alive three years after the transplant.
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.
