Stem Cell Transplant

Autologous Transplant of Stem Cells. In Leukemias and / or Lymphoma

Medical Program for Autologous Hematopoietic Stem Cell Transplantation (Bone Marrow) in Leukemias and/or Lymphoma

MEDICAL PROGRAM FOR AUTOLOGOUS STEM CELL TRANSPLANTATION

Also known as autotransplantation, where your own stem cells are removed or harvested before you receive cancer treatment that destroys them. The stem cells are extracted or harvested, either from your bone marrow or blood and then frozen. After you have received high doses of chemotherapy and/or radiotherapy, the stem cells will be thawed and given again to you. It takes approximately 24 hours for the stem cells to reach the bone marrow. After They begin to grow, multiply, and help the marrow produce healthy blood cells again.

This type of transplant is mainly used to treat certain types of leukemia, lymphomas and multiple myeloma. It is sometimes used to treat other cancers such as: testicular cancer, neuroblastoma and certain cancers in children. Specialists and scientists are looking for a way to determine how to use autotransplants to also treat other diseases such as: systemic sclerosis, multiple sclerosis (MS), Crohn's disease, and systemic lupus erythematosus (lupus).

Currently, the autologous transplant of hematopoietic progenitors, that is, the use of stem cells from the The patient's own treatment, after conditioning treatment with chemotherapy, is the most used therapy.

Advantages of autologous stem cell transplantation are that your own cells. You don't have to worry about the new stem cells attacking your body or getting a new one. infection from another person. However, there can still be rejection, meaning the cells do not They do not enter the bone marrow or produce blood cells as they should, as well as blood cells. the transplant will not be able to produce the desired effect against cancer.

A possible disadvantage of autotransplants is that cancer cells can They will be collected along with stem cells that are then returned to your body. Another disadvantage is that your system Your immune system remains the same as it was before your transplant. This means that the cancer cells were able They will escape the attack from their immune system and may be able to do it again.

To help prevent this, some medical centers treat the cells mother before they are returned to the patient to try to eliminate any remaining cancer cells. Other treatment to help kill cancer cells that may be found in returned stem cells This involves giving anti-cancer drugs after the transplant. The stem cells are not treated. After the transplant, the patient receives an anti-cancer drug to kill cancer cells that could remain in the body. Research is currently being carried out on the need to eliminate cancer cells from transplants or transplant patients and the best way to do it.
