What is non-myeloablative conditioning?
Non-myeloablative (NMA) conditioning regimens for allogeneic hematopoietic cell transplantation (HCT) are mainly immunosuppressive and less toxic to the recipients’ stem cells. NMA regimens allowed options of HCTs for patients who were traditionally not eligible due to advanced age or comorbidities.
What does Myeloablative mean?
Listen to pronunciation. (MY-eh-loh-a-BLAY-shun) A severe form of myelosuppression. Myelosuppression is a condition in which bone marrow activity is decreased, resulting in fewer red blood cells, white blood cells, and platelets.
What is the difference between an autologous and allogeneic bone marrow transplant?
Autologous: Auto means self. The stem cells in autologous transplants come from the same person who will get the transplant, so the patient is their own donor. Allogeneic: Allo means other. The stem cells in allogeneic transplants are from a person other than the patient, either a matched related or unrelated donor.
What is Haploidentical?
A haploidentical transplant is a type of allogeneic transplant. It’s also called a half-matched or partially-matched transplant. The donor is a half match for the patient.
How long does engraftment take after BMT?
Engraftment is when transplanted stem cells enter the blood, make their way to the bone marrow and start making new blood cells. It usually takes about 2 to 6 weeks to start seeing a steady return to normal blood cell counts.
What is Myeloablative busulfan conditioning?
Reduced intensity conditioning refers to a conditioning regimen that uses less chemotherapy and radiation than the standard regimen, which destroys the patient’s bone marrow cells, (a result known as myeloablation).
What does myeloablative chemotherapy mean?
Listen to pronunciation. (MY-eh-loh-a-BLAY-tiv KEE-moh-THAYR-uh-pee) High-dose chemotherapy that kills cells in the bone marrow, including cancer cells. It lowers the number of normal blood-forming cells in the bone marrow, and can cause severe side effects.
What is myeloablative HSCT?
Myeloablative HSCT is the more stringent type of treatment. This type of HSCT destroys the body’s (autoreactive) lymphocytes as well as the bone marrow. Myeloablative HSCT most commonly incorporates a BEAM (Carmustine, Cytarabine, Etoposide, Melphalan) chemotherapy protocol. The chemotherapy takes place over six days.
What is haplo HSCT?
Introduction. Haploidentical hematopoietic stem cell transplantation (haplo-HSCT) is now considered a clinical therapeutic option in patients candidate to allo-HSCT. Primary prevention and treatment of GvHD have been a major challenge in this peculiar major HLA-mismatched setting.
Does chemotherapy help or harm the patient?
Chemotherapy may help relieve signs and symptoms of cancer by killing some of the cancer cells. Doctors call this palliative chemotherapy. Some chemotherapy drugs have proved useful in treating other conditions, such as: Bone marrow diseases.
How does chemotherapy kill cancer cells?
Chemotherapy is the use of drugs to destroy cancer cells. It works by keeping the cancer cells from growing and dividing to make more cells. Because cancer cells usually grow and divide faster than normal cells, chemotherapy has a greater effect on cancer cells.
Does chemotherapy kill cancer cells?
The good news is that most normal cells will recover from the effects of chemo over time. But cancer cells are mutated (not normal) cells, and they usually do not recover from the effects of chemo. This is why chemo is good at killing many types of cancer cells.
