title: Guidelines for treatment of liver cancer.
abstract: In the treatment of hepatocellular carcinoma, the range of indications for percutaneous ablation techniques is becoming wider than surgery and intra-arterial therapies. Indeed, whereas for some years only patients with up to three small lesions were treated, with the introduction of the single-session technique under general anesthesia, even patients with more advanced disease are now being treated. Although it is understood that partial resection assures the highest local control, the survival rates after surgery are roughly comparable with percutaneous ethanol injection (PEI). The explanation is due to a balance among advantages and disadvantages of the two therapies. PEI survival curves are better than curves of resected patients who present adverse prognostic factors, and this means that surgery needs a better selection of the patients. Indications for both therapies are reported. Single-session radiofrequency (RF) ablation seems to offer better results in terms of local control and safety than transarterial chemoembolisation (TACE) in multifocal tumours. An open question remains the choice between PEI and other new ablation procedures. In our department, we use RF, PEI and segmental TACE, according to the features of the disease. In the treatment of colorectal liver metastases, the initial survival curves of thermal ablation techniques are promising. However, they are size and site dependent, so partial resection remains the gold standard. An interesting indication seems to be the treatment of breast liver metastases in selected patients.
