Abstract
We report here a surgical case of metastatic liver tumor in a 64-year-old man who was admitted to our hospital due to shock from a hemorrhagic gastric submucosal tumor, in whom an emergency partial gastrectomy was performed. Pre- and post-operative examinations revealed a metastatic liver tumor deriving from a gastrointestinal tumor (GIST) with a tumor thrombus extending into the right atrium. Extended left hepatic resection and tumor thrombectomy under assisted circulation was performed in order to prevent imminent death. c-Kit and CD34 immunostaining of the tumor were positive, and a final diagnosis of metastatic GIST of the high risk group was made. We propose that the best treatment for metastatic liver tumor from GIST is a combination of imatinib and surgery. In such cases, it is necessary to provide surgical treatment first for the metastatic liver tumor, taking great care with the thrombus/infarction of the pulmonary veins.
