Study Notes
Bone Marrow Transplant (BMT)
-
Bone marrow transplant (BMT) is a procedure used to replace damaged or diseased bone marrow with healthy bone marrow.
-
There are two main types of BMT:
-
Allogeneic BMT: Uses bone marrow from a matched donor, such as a sibling or an unrelated donor.
- High doses of chemotherapy and sometimes total body irradiation are used to destroy cancer cells in the bone marrow before the transplant.
- Bone marrow is aspirated from the donor and infused into the recipient through a central venous line.
-
Autologous BMT: Uses the patient's own bone marrow.
- Bone marrow is collected from the patient during a period of remission (when the cancer is in control).
- Approximately 1 liter of bone marrow is aspirated, usually from the iliac crest.
- The bone marrow is then frozen and stored for later use if the cancer returns.
- If the cancer returns, the patient will receive lethal doses of chemotherapy or radiation to destroy the remaining cancer cells.
- The frozen bone marrow is then thawed and infused intravenously through a central line.
-
Allogeneic BMT: Uses bone marrow from a matched donor, such as a sibling or an unrelated donor.
-
Key facts and figures:
- Autologous BMT: Bone marrow is collected during remission, frozen, and stored for later use if the cancer returns.
- Allogeneic BMT: Bone marrow is collected from a matched donor, usually a sibling or an unrelated donor.
- Preparation for both BMT types: High doses of chemotherapy and sometimes total body irradiation are used to destroy cancer cells in the bone marrow before the transplant.
-
Post-transplant:
- Autologous BMT: The patient will be critically ill and hospitalized for several weeks with a potential for complications such as malnutrition, infection, and bleeding.
- Allogeneic BMT: The patient will be critically ill and hospitalized for several weeks with a potential for complications such as malnutrition, infection, and bleeding.
-
Complications of BMT:
- The most common complications of BMT include infections, bleeding, and malnutrition.
- These complications can be serious and even life-threatening.
-
BMT results: After a BMT, the patient will need ongoing monitoring to ensure that the new bone marrow is working properly and to manage any complications.
Stem Cell Transplant (SCT)
- Allogeneic SCT involves replacing the recipient's blood cell lines with donor cells.
- The recipient undergoes chemotherapy and radiation treatment prior to SCT.
- The donor receives GM-CSF/G-CSF for 4-5 days to increase stem cell concentration in the blood.
- Peripheral blood is collected, white blood cells are separated from plasma and administered through a central venous catheter.
- Umbilical cord blood can also be used as a source of stem cells.
Graft-versus-Host Disease (GVHD)
- A complication of allogeneic SCT where donor T lymphocytes attack the recipient's body.
- Targets the liver, skin, and gastrointestinal tract.
- Acute GVHD develops within days to six months after SCT.
- Symptoms include a pruritic, maculopapular rash starting on palms and soles, extending to the entire body.
- Jaundice, diarrhea, nausea, vomiting, and dry eyes are also common.
- Chronic GVHD develops more than three months after transplant and may persist for life.
- Symptoms include chronic pain, fatigue, weakness, and shortness of breath due to lung injury.
- Treatment for GVHD includes antibiotics and corticosteroids.
Childhood Leukemia Prevalence
- Leukemia is a common childhood cancer, accounting for approximately one-third of all cases.
Childhood Leukemia Types
-
Acute Lymphoblastic Leukemia (ALL) is the most prevalent type of childhood leukemia, with peak incidence occurring between the ages of two and five.
- ALL is more common in Hispanic and White children and exhibits higher rates in boys.
- Acute Myeloid Leukemia (AML) is distributed more evenly across races and sexes.
- Juvenile Myelomonocytic Leukemia (JMML) is a rare form of leukemia primarily affecting children.
Leukemia in Children: Prevalence and Types
- Leukemia accounts for roughly one-third of all childhood cancers.
- Acute Lymphoblastic Leukemia (ALL) is the most common type of childhood leukemia, with peak incidence between the ages of 2 and 5 years.
- ALL is more frequently diagnosed in Hispanic and White children, and rates are higher in boys.
- Acute Myeloid Leukemia (AML) is more evenly distributed across racial and gender demographics.
- Juvenile Myelomonocytic Leukemia (JMML) is a rare form of leukemia primarily affecting children.
