Bone Marrow Transplant

Stem cell transplant is one modern technology that is undergoing rapid improvements. It is said these days that instead of investing in various life insurance policies that are making the rounds in the market, to secure the future and precious life of your child go for stem cell technologies. This can later cure him or her from any life threatening terminal disease like cancer. Stem cell transplant has been used in recent times as a cure for cancer, but the technique is different from the stem cell bank that is maintained these days for new born.


Who needs a stem cell transplant?

The bone marrow which is part of the bones is responsible for making blood cells. It is soft and spongy tissue lodged inside the bone having hematopoietic stem cells. These cells either turn into bone marrow cells or can turn into any other kinds of cells or the blood cells. But there are certain forms of cancers that can keep these cells from developing normally.

A patient is recommended to get a blood as well as bone marrow stem cell transplant if they are in a condition which prevents the body from producing new healthy blood cells. Some of the conditions and diseases that prevent the bone marrow from doing so are given below:

  • Cancers like Myeloma, breast cancer, leukemia, Lymphoma may require stem cell transplant
  • Blood diseases which may require are sickle cell anemia, aplastic anemia and thalassemia
  • There are immune deficiency diseases like the congenital neutropenia, severe combined immunodeficiency syndrome, chronic granulomatous disease may demand a stem cell transplant.

The oncologist or hematologist shall decide for a stem cell transplant for a patient depending upon overall age and health, severity of the diseases and other treatment possibilities.


What is a stem cell transplant?

So the stem cell transplant is a kind of treatment to treat blood disorders or any types of cancer. Even blood diseases are also treated with transplants. Previously patients had to undergo a bone marrow transplant due to the fact that stem cells are collected from the bone marrow. But today stem cells get collected from the blood. And for this particular reason they are now called stem cell transplants. Nowadays stem cell therapies are used to combat hair loss and many other aesthetic related issues.

Some of the different types of stem cell treatments available are discussed below

Autologous transplant: These kinds of transplants are known as auto transplant. This kind of transplant has the scope  of very high dose chemotherapy paired with autologous stem cell rescue. In this process usually the doctors treat the cancel and then make use of the stem cells from the patient itself. From the blood, stem cells are collected and the health care team then freezes it. These cells are usually placed back in the blood after thawing them in the frozen state post the chemotherapy. The cells take almost 24 hours to reach the bone marrow and start multiplying to give rise to healthy blood cells.

Allogenic transplantation: This is better known as an allo transplant medically. In this case stem cells are obtained from another individual. But this individual needs to be someone with whom the bone marrow of the patient matches. Due to presence of proteins in white blood cells called the human leukocyte antigens (HLA) it is important that bone marrow matching takes place. The most compatible stem cell donor will have the HLA matching with that of the patient.

But the process of matching can also give rise to a very severe condition named graft versus host disease or GVHD but then it is not very likely. In this kind of a disease the healthy cells obtained from transplantation will start attacking the cells of the patients. In such cases siblings are considered to be the best match. And if they are not available then some other close family member can also work. Once the donor is fixed then the patient starts receiving chemotherapy session with or without radiotherapy. The other person’s stem is then placed in a vein via a tube. These cells unlike the previous ones are not frozen so they can be given immediately after the completion of chemotherapy.

There can be two types of Allo transplantation depending upon the age, condition and the disease that is being addressed:

The first kind is ablative where high dose of chemotherapy is used and in the second kind milder doses of chemotherapy is employed.

When the assigned health care team is unable to find a matched adult donor then are other options that must be considered like the Umbilical cord blood transplant and these days cancer centers all around the globe make use of cord blood.

Parent child transplant and haplotype mismatched transplant: In these kinds of transplants which are commonly employed the match found is 50% instead of 100% and the donor can be a parent, child or brother and sister.
