Blood and Marrow
Transplantation is a form of intensive treatment used to treat certain cancer
like leukaemia’s, Lymphomas and some Non-cancerous Diseases like thalassaemia.
Bone marrow is found inside our bones, and is the ‘factory’ that make blood. It
is responsible for producing white blood cells (to protect against infection),
Red blood cells (to carry oxygen around the body) and platelets (to prevent
bleeding).Stem cells are blood cells at their earliest stage of development in
the bone marrow, before they have become committed to developing into white
cells, red cells or platelets. It is these stem cells which are the key Factors
in transplantation. They replace the diseased marrow as well as provide
immunity against cancer and infections.
There are two main type of Transplant –
Autologous and Allogenic.
Autologous
Transplant:
This means that the bone
marrow or stem cells used for the transplant are one’s own. A little bit of the
Patient’s bone marrow or peripheral blood stem cells is taken and stored before
high dose treatment. When the treatment is over, the bone marrow or stem cells
are given back through a vein.
