Transplant-related mortality: the number you should ask for | CION Cancer Clinics
Transplant-related mortality is the chance of dying from the transplant treatment itself, through infection, graft-versus-host disease or organ damage, rather than from the cancer returning. There is no single figure. It depends on the transplant type, donor, your fitness, your disease and the centre. Ask for the estimate for patients like you, and read it next to your relapse risk without a transplant. This page shows how. At CION Cancer Clinics, our haematology team assesses whether a transplant or CAR-T fits your situation and coordinates care with qualified centres.

The short answer
What is transplant-related mortality?
Transplant-related mortality is the chance of dying from the transplant treatment itself, rather than from the blood cancer coming back. It is not one fixed figure. It varies widely with the type of transplant, the donor, your fitness, your disease and the centre, so the number worth asking for is the one for patients like you, at the centre you are considering.
Why doctors track it separately
After a transplant, people can die for two broad reasons. The cancer can return, which is called relapse. Or the treatment can cause fatal harm through infection, organ damage or the donor cells attacking the body. Doctors often call the second group non-relapse mortality. Keeping the two apart shows whether a transplant is lowering the cancer risk at too high a price.
Why this page gives no percentages
Published figures come from different countries, eras and patient groups. A number from one study can badly mislead someone whose situation is different. What you need is an honest estimate from the team treating you, explained against your own risk of relapse without a transplant.
Asking about this risk is not pessimism. It is part of giving informed consent to a major treatment.Where the risk comes from
What causes deaths related to a transplant?
Most of these are watched for closely and treated early. Knowing them helps you spot warning signs at home.
Infection
With the immune system wiped out, bacteria, viruses and fungi that a healthy body shrugs off can become life-threatening. Infections remain a risk for months, until immunity rebuilds.
Graft-versus-host disease
In a donor transplant, the donor's immune cells can attack the skin, gut, liver or lungs. It ranges from a mild rash to a severe illness. It does not happen with own-cell transplants.
Organ damage
The high-dose treatment can injure organs.
Examples your team watches for
- Liver blockage called veno-occlusive disease
- Lung inflammation
- Kidney or heart strain
Graft failure and bleeding
Rarely, the new cells do not take, leaving blood counts too low. Low platelets can also cause serious bleeding before the marrow recovers.

What tends to raise or lower the risk?
Tends to lower the risk
Tends to raise the risk
An own-cell transplant
A donor transplant, especially from a less well matched donor
Good fitness and few other illnesses
A high comorbidity score or frailty
Disease in remission at the time of transplant
Active disease, or many earlier lines of treatment
Infections cleared before admission
Active or recent serious infection
A caregiver close by and quick return when unwell
Delay in reporting fever or new symptoms after discharge
The number you should ask for
How do you ask for the risk, and how should you read the answer?
Ask the transplant team directly: "For someone with my disease, my fitness and this type of donor, what is the risk of dying from the transplant itself?" Then ask how that compares with the risk of the cancer returning if you do not have a transplant.
Ask what the number is based on
Is it from the centre's own patients or from published studies abroad? Over what period after the transplant was it measured? Does it include patients like you in age, disease and donor type? A figure from the centre's own recent results is usually more relevant than a textbook one.
Read it alongside the other number
A transplant risk only makes sense next to the relapse risk without it. A modest treatment risk can be worth taking if the cancer is very likely to return otherwise. The same risk may not be worth taking for a cancer that is well controlled already. If the team gives you only one of the two numbers, ask for the other.
If a centre cannot or will not discuss its own outcomes, that itself is useful information.Leave a number, we will call you

Over time
When is the risk highest after a transplant?
-
The first weeks in hospital
Before the new cells start working, blood counts are at their lowest. Infections, bleeding and mouth and gut soreness are the main concerns.
-
When the new cells take
Counts begin to rise. In donor transplants, early graft-versus-host disease can appear around this time, often as a rash, loose motions or liver changes.
-
The first months at home
Immunity is still weak, and medicines to control graft-versus-host disease lower it further. Viral infections and returning fevers need quick attention.
-
The first year and beyond
The risk falls steadily but does not disappear. Long-term graft-versus-host disease, late infections and effects on the heart, lungs and hormones are checked at follow-up visits.
Commonly believed
What do families often believe about transplant risk?
"If we ask about death, the doctors will think we have lost hope."
Transplant teams expect this question and should welcome it. You cannot weigh a major treatment without knowing its risks.
"Once discharged, the danger is over."
A large share of serious problems appear after going home. Fever, breathlessness, rash or loose motions after a transplant need the team's advice the same day.
"A lower number from one hospital means it is the safer place."
Not necessarily. Centres treat different mixes of patients. A centre that takes on sicker patients may report a higher figure. Ask who was included before comparing.
"An own-cell transplant has no serious risk."
It is lower, but real. Infections during the low-count period can still be serious, especially in older or less fit people.
Being straight with you
What can this number not tell you?
A risk figure describes what happened across a group of patients. It cannot tell you what will happen to you or your parent. Some people with a higher estimated risk do well, and some with a low one face serious complications.
Who should think hardest about this risk
People who are frail, who have serious heart, lung or liver disease, or whose cancer is not responding to treatment carry more risk with less chance of benefit. For them, a transplant may not be the right choice, and that deserves an open conversation.
It also cannot capture quality of life
A mortality figure says nothing about how people feel in the months after a transplant. Long-term graft-versus-host disease, tiredness, time away from work and repeated hospital visits all affect daily life. Ask the team what recovery usually looks like for someone in your position, and what support the family will need at home.

Questions we are asked
Common questions about transplant-related mortality
Is transplant-related mortality the same as the survival rate?
No. Survival includes everyone who is alive after a period of time, whatever happened to their cancer. Transplant-related mortality counts only deaths caused by the treatment, not by relapse. You need both pictures, and your haematologist can explain how each applies to you.
Why is the risk higher for donor transplants?
Donor transplants add graft-versus-host disease and need medicines that lower immunity for longer. That means more infections over a longer time. The same donor immune cells also fight the cancer, which is why the higher risk can still be worth taking.
Does a half-matched donor mean much higher risk?
Half-matched transplants from a parent, child or sibling have become much safer with newer methods of preventing graft-versus-host disease. The risk compared with a full match depends on the centre's experience and the patient. Ask the centre about its own results with half-matched transplants.
Can the risk be reduced before the transplant?
Some of it. Treating infections, dental problems and poorly controlled diabetes, building strength, and choosing lighter conditioning where suitable can all help. Getting the disease into remission first also matters. Your team will advise what is realistic for you.
What warning signs at home need a same-day call?
Any fever, shivering, new breathlessness or cough, a spreading rash, loose motions, yellow eyes, bleeding or confusion. Call the transplant team straight away. If you cannot reach them and the person is very unwell, go to the nearest emergency department or call 108.
Should we compare centres by their mortality figures?
Use them carefully. Ask how many transplants of your type the centre does, which patients were counted, and over what period. A single number without that context can mislead. Experience with your specific disease and donor type often matters more.
Will the doctor give us the figure in writing?
Many centres include the main risks in the consent form and discussion notes. You can ask for a written summary of the risks discussed. It helps family members who could not attend, and gives you something to check your understanding against later.
If the risk seems too high, what then?
Say so and ask about alternatives, such as lighter conditioning, a different donor, other medicines or continuing current treatment. You can also seek a second opinion. Deciding against a transplant after a careful discussion is a valid choice, and care continues.
