The first physician to perform a successful human bone-marrow transplant on a disease other than cancer was Robert A. Good at the University of Minnesota in 1968. [74] In 1975, John Kersey, also of the University of Minnesota, performed the first successful bone-marrow transplant to cure lymphoma.
Myelodysplastic syndrome (MDS) is a form of blood cancer in which the bone marrow no longer produces enough healthy, normal blood cells. [9] MDS are a frequently unrecognized and rare group of bone marrow failure disorders, yet the incidence rate has rose from 143 reported cases in 1973 to approximately 15,000 cases in the United States each year.
Randomized clinical trials reported treatment-mortality rates from 0% to 7% for women who received the HDC/BMT treatment, versus no such deaths within the control groups that received the typical chemotherapy regimen. [4] In HDC, the bone marrow transplantation was used to maximise chemotherapeutic dosage.
Overall, the five-year survival rate is higher than 75% among recipients of bone marrow transplantation. [39] Older people (who are generally too frail to undergo bone marrow transplants) and people who are unable to find a good bone marrow match have five-year survival rates of up to 35% when undergoing immune suppression. [40] Relapses are ...
Furthermore, a 5–10% treatment-associated mortality rate is associated with allogeneic stem-cell transplant. People over age 65 and people with significant concurrent illnesses often cannot tolerate stem-cell transplantation.
In comparison, the median life expectancy for all forms of MPS type I was 11.6 years. Patients who received successful bone marrow transplants had a 2-year survival rate of 68% and a 10-year survival rate of 64%. Patients who did not receive bone marrow transplants had a significantly reduced lifespan, with a median age of 6.8 years. [4]
Hematopoietic stem cell transplantation (HSCT) is the transplantation of multipotent hematopoietic stem cells, usually derived from bone marrow, peripheral blood, or umbilical cord blood. [16] [17] [13] It may be autologous (the patient's own stem cells are used), allogeneic (the stem cells come from a donor) or syngeneic (from an identical twin).
The only treatment that has resulted in cures for JMML is stem cell transplantation, also known as a bone marrow transplant, with about a 50% survival rate. [3] [11] The risk of relapsing after transplant is high and has been recorded as high as 50%. Generally, JMML clinical researchers recommend that a patient have a bone marrow transplant ...
