title: [Current status of treatment for small hepatocellular carcinoma].
abstract: In recent years ethanol injection therapy (PEI) and transcatheter hepatic arterial embolization (TAE) have come to be widely used in the treatment of small hepatocellular carcinoma, and the introduction of microwave coagulation therapy (MCT) more recently has made it possible to perform a variety of non-surgical treatments even in cases in which surgical resection has been indicated until now. There have also been reports based on survival rates that results comparable to those obtained by surgical resection can be achieved with non-surgical methods. The main issue is whether PEI or resection should be selected to treat small hepatocellular carcinomas. However, the recurrence rate after PEI is higher than after surgical resection, and according to our results, in patients with solitary lesions, especially when the tumor diameter is 2 cm or less, the level of malignancy in many cases is also low biologically, and postoperative survival rates (recurrence-free survival rates) are favorable [5 years : 85.0% (64.3%); 10 years: 67.9% (42.2%)]. After thoroughly evaluating liver function in these cases, while surgical resection should be considered first, it is also important to use a combination of various treatment methods rather than always resort to a single method.
