How response to systemic treatment for liver cancer is assessed | CION Cancer Clinics
Response is judged mainly by comparing a new contrast CT or MRI with the scan taken before treatment began. The AFP trend, your liver function and how you feel are read alongside it. This page explains what the team looks at, when scans happen, what words like stable disease and partial response mean, and why a tumour that is not shrinking can still be a good result. At CION Cancer Clinics, a multidisciplinary tumour board weighs your liver function and your scans before recommending any treatment.

The short answer
How will the doctors know if the treatment is working?
Mainly by comparing scans. A contrast CT or MRI taken before you start is set beside a new scan taken a few cycles in, and the team asks whether the living tumour has shrunk, held steady or grown. The AFP blood test, your liver function and how you are actually feeling are read alongside the scan, never instead of it.
Who this page is for
This page is for people with primary liver cancer (hepatocellular carcinoma, or HCC) who are on systemic treatment: immunotherapy such as atezolizumab plus bevacizumab, or tablets such as lenvatinib or sorafenib. If your cancer started in the bowel or elsewhere and spread to the liver, response is judged differently, and your own cancer team is the right place to ask.
Why one scan is never the whole answer
Liver tumours often change in texture before they change in size. A tumour can look much the same width while most of it has stopped receiving blood and died. That is why the radiologist looks at which parts still light up with contrast, not only at the ruler.
Response is a judgement made over time, by a team, across several pieces of evidence.Four things together
What does the team look at when they check response?
No single result decides whether treatment continues. These four are read side by side at each review.
The scan
A triple-phase CT or a contrast MRI, compared with the scan taken before treatment. CION arranges these through diagnostic partners, and the tumour board reviews the images, not only the written report.
The AFP trend
If your AFP was raised at the start, a steady fall is encouraging and a steady rise is a warning. One reading means little. The trend over time matters far more.
If your AFP was normal to begin with, it cannot be used to track response.Liver function
Bilirubin, albumin and INR show how well the liver itself is coping. A tumour can be controlled while the liver around it weakens, and that changes what is safe to give next.
How you are
- Appetite and weight
- Energy and daily activity
- Pain, swelling or new fluid in the abdomen
- Side effects and how well you tolerate them

What happens at a response check, step by step?
Blood tests before every cycle
Liver function, blood counts, kidney and thyroid tests are checked before each treatment. These are about safety first. They also show early whether the liver is under strain.
A planned scan every few cycles
Your oncologist sets the timing at the start. It is often every two to three months, earlier if symptoms change. Use the same type of scan each time, ideally at the same centre, so the pictures can be compared fairly.
The radiologist measures the living tumour
The report compares the main tumours with the baseline scan and looks for any new spots in the liver, the lungs or the bones.
The team decides together
Scan, AFP, liver tests and your own account are put together. The decision is one of three: carry on, adjust the dose or timing, or move to a different treatment.
On your scan report
What do the response words on the report mean?
- mRECIST
- Modified RECIST. A way of measuring liver cancer that counts only the part of the tumour still lighting up with contrast, which is the living part.
- Complete response
- No living tumour can be seen on the scan. It does not mean every cancer cell has gone, so treatment and scans usually continue.
- Partial response
- The living tumour has shrunk by a clear, measured amount. This is a good result, and treatment usually continues.
- Stable disease
- Neither clearly shrinking nor clearly growing. On systemic treatment, holding the cancer steady is a real benefit and often reason to carry on.
- Progressive disease
- The tumour has grown beyond a set amount, or new tumours have appeared. This usually starts a conversation about changing treatment.
- Pseudoprogression
- An uncommon pattern on immunotherapy where a tumour looks bigger for a while because immune cells have moved in, before it later shrinks.

Commonly believed
What do families often get wrong about response?
"If the tumour is not shrinking, the treatment has failed."
With systemic treatment for liver cancer, keeping the tumour steady is a meaningful result. Many people who benefit never see a dramatic shrink on the scan. Stable disease is usually a reason to continue, not to stop.
"The AFP went up a little, so the cancer is spreading."
AFP can wobble between tests, and it can rise for a while when tumour cells are breaking down. A single small rise is watched, not acted on. Your team looks for a steady pattern across several results before reading anything into it.
"Feeling worse means the drug is not working."
Tiredness, poor appetite or loose stools are often side effects rather than signs of growth. Tell your team about every change. Many side effects can be eased with a dose adjustment without giving up the treatment.
"A scan from any centre will do for comparison."
Different machines and different contrast timing can make the same tumour look different. Carry your earlier scans on a CD or link to every visit, so the radiologist compares like with like.
Being straight with you
What this page cannot tell you
It cannot read your scan. Whether a change on your report is meaningful depends on the images themselves, your earlier scans and how your liver is coping. Only the team treating you can put those together.
Who this does not apply to
This page does not describe how response is judged after TACE, ablation or surgery. Those are read differently, and response after TACE has its own page. It also does not apply to bile duct cancer or to cancer that spread to the liver from another organ.
What a result does not predict
A good response does not tell you how long it will last, and a poor one does not mean nothing else can be done. Bring your reports and ask your oncologist what this result changes in your plan. If you want another view, a second opinion at CION includes a tumour board review of your scans.
Questions we are asked
Common questions about checking response
When is the first response scan usually done?
Usually after a few cycles, often around two to three months in, though your oncologist sets the timing for you. It is done sooner if new symptoms appear. Scanning too early can mislead, because some tumours take time to respond, especially on immunotherapy.
Is a PET-CT better for checking response?
Usually not for HCC. Many liver cancers do not show up well on a standard PET-CT, so a triple-phase CT or contrast MRI is the normal choice. PET-CT may be used to look for spread outside the liver in particular cases. Your team will say which scan suits you.
My AFP is falling but the scan looks the same. Is that good?
Often it is encouraging. A falling AFP with a stable scan can mean the tumour is being held in check, or that parts of it have died without changing size. Your team reads the two together, and the next scan usually makes the picture clearer.
What if the scan shows a new spot?
A new spot is taken seriously, but not every new mark is cancer. Small cysts, scars and blood vessels can appear on a sharper scan. The radiologist and tumour board decide whether it is new cancer, and sometimes a short-interval repeat scan is needed before anyone is sure.
Can treatment continue if the cancer grows slightly?
Sometimes. If you are feeling well, the liver is coping and the growth is small, an oncologist may continue and repeat the scan sooner, especially on immunotherapy. If growth is clear or you are getting worse, a change of treatment is usually discussed.
Why are liver tests checked before every cycle?
Because the treatment, the tumour and any cirrhosis all affect the liver. Immunotherapy can occasionally cause immune hepatitis, and a weakening liver changes which drugs are safe. These tests protect you as much as they track the cancer.
Should I get my scans done at the same centre each time?
Where possible, yes. Comparing scans from the same type of machine and the same contrast timing is far more reliable. If you must change centre, carry every earlier scan on a CD or link so the new radiologist can compare properly.
Who explains the scan result to us?
Your medical oncologist, ideally at a planned visit where family can be present or join by phone. Ask what the result means for the plan, not only what the numbers say. Call the CION helpline if you need help arranging a review of your scans.
