A stem cell transplant| (sometimes called a bone marrow transplant) allows your child to have much higher doses of chemotherapy than usual. This can improve the chance of curing their cancer but has more side effects.
Bone marrow is a spongy material that’s found inside some of our hollow bones. The bone marrow contains stem cells|. These are cells at a very early stage of development that develop into the three different types of blood cell. When the cells are fully mature, they are released into the bloodstream.
Before a stem cell transplant, stem cells are collected from either the bone marrow or the blood.
Your child will then be given very high doses of chemotherapy|, usually over a few days. Sometimes, radiotherapy| to the whole body, known as total body irradiation (TBI), is also given.
As well as destroying any remaining cancer cells, the high doses of chemotherapy also destroy the stem cells in the bone marrow.
After the chemotherapy, your child is given the stem cells that were collected before the treatment through a drip. They make their way into the bone marrow and start producing mature blood cells again.
There are two main types of transplant:
This uses your child’s own stem cells. The stem cells are collected some time before the high-dose treatment and are stored until needed.
This uses stem cells from a donor - it’s also known as an allograft. An allogeneic transplant is a more complicated procedure than an autologous one and is only carried out in specialist hospitals. Recovery may take several months or longer.
The CCLG| also has booklets about transplants, including Ben’s bone marrow transplant|. This booklet tells Ben’s story from his initial visit to hospital through to life after his transplant.
