How many TACE sessions will I need for liver cancer? | CION Cancer Clinics
There is no fixed number of TACE sessions. Some people need only one, many need two or three, and the decision is made one session at a time after each follow-up scan. This page explains what shapes the number, how the team decides whether to repeat, and when more sessions stop making sense. At CION Cancer Clinics, a multidisciplinary tumour board weighs your liver function and your scans before recommending any treatment.

The short answer
How many TACE sessions does a person with liver cancer usually need?
There is no fixed number. Some people need one TACE session, many need two or three, and a few have more spread over a longer period. The number is decided one session at a time, by looking at the scan after each treatment and at how well the liver coped.
Why nobody can promise a number on day one
TACE (transarterial chemoembolisation) delivers chemotherapy straight into the blood vessels feeding a liver tumour and then blocks those vessels. How much of the tumour dies after one session depends on its size, how many tumours there are and how its blood supply is arranged. None of that is fully known until the first follow-up scan comes back.
Which page this is
This page is about primary liver cancer, hepatocellular carcinoma (HCC), the cancer that starts in the liver itself. If your scan shows cancer that spread to the liver from the bowel or elsewhere, read about TACE for liver metastases instead. The way sessions are counted there is different. For the procedure itself, start with TACE explained.
The real question is not how many sessions. It is whether each session is still helping, and whether the liver can take another one.What the team weighs
What decides whether I need one session or several?
Four things shape the count. Your doctors look at all of them together, not one in isolation.
The size and number of tumours
A single tumour with a clear blood supply may be fully treated in one go. Large tumours, or several tumours in both halves of the liver, are often treated in stages, one part of the liver at a time.
Often needs more sessions
- A large tumour
- Tumours in both lobes of the liver
- Several separate feeding vessels
How the tumour responded
If the scan after the first session shows the tumour has no living, blood-filled part left, there may be nothing more to treat for now. If part of it is still lighting up, another session may target what is left.
How well your liver coped
Every session puts some strain on the healthy liver around the tumour. If your bilirubin rises, fluid builds up in the abdomen or your Child-Pugh score worsens, the team may stop TACE even if tumour remains. Read more on liver failure after TACE.
The goal of treatment
When TACE is used to keep a tumour in check before surgery or a transplant, the plan is shaped by that next step. When it is the main treatment, sessions continue only while they are still controlling the cancer.
Your goal is worth asking about directly at the first meeting.Not sure whether this applies to you?
Ask an oncologistOne session at a time
How does the team decide whether to do another TACE?
The first session
An interventional radiologist threads a thin tube from the groin or wrist into the liver's arteries and treats the tumour. CION coordinates this through NABH-accredited partner hospitals, and your team will tell you where it takes place.
Recovery and blood tests
Most people feel unwell for a few days with pain, fever or nausea. Liver blood tests are checked to see how the healthy liver handled the treatment.
The follow-up scan
CION arranges a contrast CT or MRI some time later. It shows which parts of the tumour still have a blood supply, meaning living cancer, and which parts are dead.
The tumour board review
The tumour board reviews the scan alongside your blood tests and how you are feeling. They decide on another session, a pause with regular scans, or a change to a different treatment.
Repeat only if it still helps
This is called on-demand TACE. A further session is booked because the scan shows something to treat, not because a fixed course was set at the start.
On your scan report
What do the words on my post-TACE scan mean?
- Complete response
- No living, blood-filled tumour is seen. It does not mean the cancer is gone for good. Scans continue because new tumours can appear.
- Partial response
- The living part of the tumour has shrunk clearly, but some remains. Another session is often considered.
- Stable disease
- The tumour has neither shrunk much nor grown. What happens next depends on how many sessions you have had and how your liver is doing.
- Progressive disease
- The tumour has grown or new tumours have appeared. This can be a sign that TACE is no longer the right tool.
- Lipiodol uptake
- An oily contrast used in conventional TACE that collects in the tumour. Dense uptake on CT usually means the drug reached its target.
- mRECIST
- The measuring system most teams use after TACE. It counts only the living, enhancing part of the tumour, not its total size. See how response is measured.
Leave a number, we will call you
One field. No form to fill in, and no charge for the call.
Did you know
A dead tumour often does not shrink much on the scan. It can stay roughly the same size while having no blood supply at all. That is why doctors look at which parts still light up with contrast, not just at the measured size.
Knowing when to stop
When do doctors stop doing more TACE sessions?
More sessions are not always better. Doctors stop TACE when it is no longer doing its job, or when the liver can no longer take it. Stopping is not giving up. It usually means switching to a treatment that suits the situation better.
Signs TACE has stopped working
If two sessions in a row fail to control the same tumour, or new tumours keep appearing between sessions, the cancer may have become resistant to TACE. Doctors call this TACE refractoriness. The usual next step is systemic treatment, such as immunotherapy or targeted tablets, planned at CION. Read when TACE stops working for how this is judged.
Who repeat TACE does not suit
Repeat sessions are usually not offered if your liver function has slipped to Child-Pugh C, if the main portal vein is blocked by tumour, if the cancer has spread outside the liver, or if you are too unwell to recover between sessions. In these situations each extra session carries more risk than benefit.
If you feel your family is being told to stop too soon, a second opinion from a tumour board is a reasonable thing to ask for.Being straight with you
What this page cannot tell you
It cannot tell you how many sessions you will need. That depends on your scans, your liver blood tests and the judgement of the team who has seen them. Two people with the same stage on paper can need very different numbers of sessions.
It cannot predict how long TACE will hold the cancer
Some tumours stay controlled for a long time after one or two sessions. Others come back quickly. Nobody can tell in advance which one yours will be, and any page that gives you a number for that is guessing.
It cannot read your scan
If you are holding a post-TACE report, the words on it only make sense next to the images and your earlier scans. Bring both to your oncologist, or ask CION to arrange a review by the tumour board.
Budgeting for more than one session is sensible. The TACE cost page explains what each session usually includes.Questions we are asked
Common questions about the number of TACE sessions
Is one TACE session ever enough?
Sometimes, yes. A single tumour with a clear blood supply can show no living cancer on the scan after one session. You will still have regular scans afterwards, because new tumours can appear elsewhere in a liver with cirrhosis. Further sessions are booked only if something new or remaining needs treating.
Why did my doctor not give me a fixed course of sessions?
Because most teams now repeat TACE on demand, based on the scan after each session. A fixed schedule would mean treating tumours that are already dead and putting needless strain on the liver. Deciding one session at a time protects the healthy liver you need for later treatment.
Does needing more sessions mean the cancer is worse?
Not necessarily. Large tumours or tumours in both halves of the liver are often planned in stages from the start. What matters more is whether each session controls the tumour it targets. Ask your doctor whether the extra session is part of the plan or a response to growth.
Is there a maximum number of TACE sessions?
There is no single agreed limit. The real limits are your liver function and whether the cancer is still responding. Doctors become cautious when two sessions in a row fail, or when liver blood tests are worsening after each one. At that point another treatment is usually safer.
Can TACE be combined with other treatments to reduce sessions?
Sometimes TACE is combined with ablation for a medium-sized tumour, or with immunotherapy or targeted tablets. Whether this reduces the number of sessions is still being studied. Read TACE combined with systemic treatment and ask whether a combination fits your case.
Does each session cost the same?
Usually each session is billed separately, and the price varies with the hospital, the type of TACE and the length of stay. Bead TACE often costs more than conventional TACE. Ask for a written, itemised estimate for each session, and check what your insurance or scheme covers before the first one.
Will I feel worse after each session?
Most people get some pain, fever and nausea for a few days after each session, which doctors call post-embolisation syndrome. It does not usually get worse with each session. If you feel much worse than last time, or turn yellow, tell your team quickly.
Who should I talk to about my number of sessions?
Your medical oncologist and the interventional radiologist who does the procedure, ideally together at a tumour board. If you are unsure whether more sessions make sense, call the CION helpline. Someone will arrange for your scans and reports to be reviewed and explain the options honestly.
