When TACE stops working: what refractoriness means and what comes next | CION Cancer Clinics

It means repeated TACE sessions are no longer controlling the cancer, and another round is unlikely to help. When that happens, the usual next step is systemic treatment, meaning immunotherapy or tablets that work through the bloodstream, provided your liver is still strong enough.

This page is about primary liver cancer, hepatocellular carcinoma (HCC), the cancer that starts in the liver itself. It is mostly read by families of someone at BCLC stage B, the intermediate stage, where TACE is the standard first treatment. If the cancer in the liver spread there from the bowel, breast or elsewhere, the decisions are different and sit with the team treating that cancer.

The word doctors use

Specialists call this TACE refractoriness, or TACE failure. TACE is chemoembolisation: a thin tube is passed through an artery to the tumour, chemotherapy is released there, and the blood supply is blocked. You can read how it works on the TACE procedure page. Refractoriness is not a sudden event. It is a judgement the team makes after looking at several scans in a row.

Not everyone whose scan shows some live tumour after TACE is refractory. One incomplete result after a first session often means the tumour needs another session, perhaps with the tube placed differently. Large tumours commonly need more than one. Declaring failure too early takes away a treatment that might still work.

When systemic treatment is the wrong step

Immunotherapy and tablets are not suitable for everyone. They are usually avoided when the liver is badly damaged, at Child-Pugh C, when the person is bedbound most of the day, or after a liver transplant, where immunotherapy can trigger rejection. In those situations the most useful care is often careful symptom control, which CION provides at its centres.

When TACE was never the right tool

Sometimes the problem is that the cancer was beyond TACE from the start, for example with a tumour in the portal vein. That is a different conversation, covered on our page about treatment for advanced liver cancer. The choice between tablets and immunotherapy in more detail is on systemic treatment options.

It cannot tell you whether TACE has stopped working for you. That depends on comparing your actual scans over time, the position and size of each tumour, and how your liver has coped. Only the team holding those images can make that call.

It cannot tell you how long treatment will work

Nobody can give an individual timeline from a page. How a cancer behaves on the next treatment varies a great deal between people, even at the same stage, and averages from trials do not describe one person.

Who to ask

Ask your treating oncologist directly: has TACE stopped working, what evidence shows it, and is my liver strong enough for the next step? If the answer feels unclear, a second look from a tumour board is a reasonable request, and our page on getting a second opinion explains what to bring.
