[ Summary ] Imatinib is acceptable as a first-line therapy for hepatic metastases arising from GISTs. Because of high recurrence rates, indications for hepatic resection should be limited to cases with only one or a minimal number of lesions in the liver which have metastasized along with long recurrencefree intervals. The primary effect of imatinib is not considered to be complete response. To enhance the resistance provided by imatinib, surgical resection of metastatic GISTs is required. The timing of resection for liver metastasis is currently a topic of discussion. The clinical importance of a multimodal approach has increased, including dose-up of imatinib, intaking of sunitinib, clinical research, transarterial embolization (TAE) and radio frequency ablation (RFA).
