Autologous stem cell transplant
About autologous transplants
In an autologous stem cell transplant your own cells are used to replace cells which have been destroyed by high-dose chemotherapy and/or radiotherapy (depending on your disease). We harvest (collect) some of your stem cells before the high-dose treatment because it destroys both cancer cells and healthy blood cells. It also affects the bone marrow’s ability to produce stem cells and increases your risk of infection because it lowers your level of white blood cells.
Following your treatment we return (infuse) the healthy stem cells collected before your treatment back into your body. By doing this we ‘rescue’ your bone marrow from the damaging effects of the high-dose treatment. The infused cells start to make blood cells again and help your blood levels return to normal. Depending on your disease, the aim of the stem cell transplant will be to prolong your remission (time when there are no signs of cancer) or cure your illness.
What happens when you have an autologous transplant
In the first stage of treatment you will receive high-dose chemotherapy, also called conditioning chemotherapy. This chemotherapy destroys as many cancer cells as possible that are still in your body after you have completed your standard-dose treatment. Unfortunately, it also destroys other blood cells, significantly reducing your blood count (the levels of blood cells in your blood). Your team will see you every day and monitor you closely during the high-dose treatment.
Stem cell infusion (return)
The next step is to reintroduce (infuse) your stem cells, either 24 or 48 hours after the start of your last chemotherapy. Stem cell infusion is painless and is very much like having a blood transfusion. It usually takes between one and two hours to complete.
The infused stem cells will find their way straight back into your bone marrow. From there they begin to grow and form new blood cells, which usually takes between 10 and 14 days.
These may include:
- Routine blood tests
- MUGA (multiple gated acquisition)
- ECG (electrocardiogram)
- GFR (glomerular filtration rate)
- Lung function test (known as a pulmonary function test)
- A bone marrow test or biopsy
- CT scan (computerised tomography)
- PET scan (positron emission tomography)
- MRI scan (magnetic resonance imaging)
From the start of treatment to the time you leave hospital after your transplant is usually between three and four weeks. Your medical team will keep you informed as your treatment progresses and when you are ready to go home they will develop a discharge plan for you.
