Hepatocellular carcinoma (HCC) is a common and difficult‐to‐treat malignant tumor. Surgical interventions are feasible in only a small proportion of patients, and non‐surgical therapy has been frequently administered to patients with inoperable HCC. Various modalities of loco‐regional therapy have gained much interest during the past decade. Among them, transarterial chemoembolization (TACE), percutaneous injection of ethanol (PEI) or acetic acid (PAI), radiofrequency ablation (RFA) and microwave coagulation therapy (MCT) are effective treatment options. TACE can target multiple hypervascular tumors but has the potential risk of inducing hepatic or renal failure. PEI is a well‐established method for small (< 3 cm) HCC, and PAI has the advantage over PEI as being more effective with fewer treatment sessions. RFA has excellent tumor ablation ability, and has been extended to treat medium‐ or large‐sized HCC. However, the overall complication rate may be higher than previously assumed. MCT is similar to RFA in its clinical application and adverse effects. Although combination therapy often achieves a higher response rate, the side‐effects may also be additive. Other therapies, such as injection of hot saline or yttrium‐90 microspheres, interstitial laser photocoagulation and cryoablation are seldom used nowadays. Thalidomide may be useful in a minority of HCC patients, whereas radiotherapy, chemotherapy and tamoxifen are generally ineffective. In conclusion, although long‐term survival in patients with inoperable HCC is possible in selected patients, the overall prognosis remains unsatisfactory, especially in those with aggressive tumor behavior. Newer antitumor therapy with better treatment efficacy is urgently needed. Information of the design for a more comprehensive approach using the existing therapeutic options may help refine the treatment strategy.
