Transarterial Chemoembolisation is an x-ray-guided procedure that delivers chemotherapy directly to the liver cancer via the arteries. A thin catheter inserted through the groin is guided to the artery supplying blood to the liver. The catheter is placed as close to the cancer as possible, then chemotherapy and is injected slowly and directly into the tumour. Embolic agents are then injected to starve the tumour of its blood supply and to increase the duration of action of the chemotherapy. X-ray images are taken and reviewed to assess whether the tumour has been treated adequately.
The procedure generally takes approximately 1.5 hours. Depending on the size, location, and the number of tumours, further treatments may be required. In almost two-thirds of cases, TACE can cause tumours to shrink or stop them from growing.
