When things go wrong with the bone marrow, it leads to a life-threatening situation. A mass of tissue with a dense network of nerves and highly vascularized bone marrow as the name suggests is found enclosed in bone cavities all over the body. It is part of the vital lymphatic system comprising red marrow and yellow marrow.
This lymphatic system performs a number of vital functions besides the
removal of old and dead cells from the body. Most of the platelets, white and blood cells are formed in the red marrow while the white marrow produces
fats, cartilage, and bone. This makes the microarchitecture a vital system for
life support. The red blood cells perform the function of oxygen carriers while
the white ones act like the sentinels and are indispensable for body immunity
which keeps harmful pathogens at bay.
During a lab test excess production of red blood cells or white blood
cells is an indication of an abnormality and calls for medical attention. For
example, excess white cell production in your bloodstream is usually a sign
of disease. In a contingency especially when there is a deficiency of the RBC,
WBC, or platelets body hormones trigger excess production to make up for the
loss.
Bone Marrow Transplant
When contingency strikes and the marrow becomes diseased to the point of
no return then a transplant is the only recourse. In the case of cancers of various
types and blood-related disorders, transplantation is lifesaving.
In this kind of procedure, stem cells play a major role. Stem cells
are a special type of developing cells that turn into the RBC, WBC, and platelets
depending upon their genetic coding. Thus, the diseased cells are removed and
healthy stem cells are transplanted into the bone marrow. The success rate of
this procedure is almost 85% and immensely helps those suffering from bone
marrow disease especially those afflicted by cancer.
BMT or bone marrow transplant is required not only when the marrow is
affected by cancer but the damage is also by severe infections, aplastic
anemia, sickle cell anemia, and thalassemia.
In case of a malignancy, BMT is most successful in the following
instances
- ·
Hodgkin’s
lymphoma
- ·
Non-Hodgkins
Lymphoma
- ·
Multiple
Myeloma
- ·
Acute
Myeloid Leukemia
- ·
Chronic
Myeloid Leukemia
- ·
Acute
Lymphoblastic Leukemia (
- ·
Neuroblastoma
- ·
Myelofibrosis
Usually, the marrow is harvested from some specific bones in the body in
order to find an anomaly or damage to it. The harvesting is done under general
anesthesia and complications are limited. In the case of harvesting from a donor, most countries have stipulated a limit to extraction.
Allo & Auto Transplant
In the case of ALLO, the transfer takes place between two persons provided
the marrows match. In order to prevent rejection a protein named HLA in WBC is
matched, this protein is responsible for preventing a rejection whence the
introduced cells begin attacking those already present in the body. ALLO transplant can be impacted with a high
or low dosage of chemotherapy and thus the process is differentiated
accordingly by the experts.
In the case of AUTO Transplant, the healthy stem cells are removed and
stored as frozen before chemotherapy or radiation. These cells are then
retransferred after the cancer treatment.
The pre-transplant procedures include increasing the production of
healthy stem cells, the chemotherapy is then carried out followed by
reinjection of the bone marrow.
Some other types of BMT are:
- ·
Syngeneic
Transplant
- ·
Haploidentical
Transplant
Before the BMT takes place a number of tests have to be conducted in
order to detect problems and infection if any. Hence a variety of blood tests, CT scans, X-rays,
biopsies, and heart function tests are all that the operating surgeon may deem
necessary.
Though the success rate is high almost up to 85% some complications may
arise post the procedure. But the complications rarely result in death and as a
result, they are becoming more and more popular.
Nearly 100000 BMT are being carried out around the world. The rate of
increase in the procedures being carried out is 7 percent which is suggestive of a growing number of ailments that afflict the marrow.
In India, a number of bone marrow transplants are being carried out in
top-rated hospitals. The cost of this procedure ranges anywhere from 20 lakhs
to 45 lakhs. The cost difference arises from the type of hospital chosen and
the BMT procedure itself. As compared to India the cost of BMT in The USA is as
much as 200,000 USD.
Some of the best hospitals for BMT are:
- ·
Max
Hospitals
- ·
Medanta
- ·
Kokilaben
Dhirubhai Ambani Hospital
- ·
Global
Hospital Chennai
The cost difference and the quality of service available in Indian
Hospitals make them an attractive health travel destination. These factors are
proving beneficial to international health travelers and they are actively
seeking treatments in India.
