LEIOMYOSARCOMA OF THE STOMACH WITH SYNCHROMOUS AND METACHRONOUS LIVER METASTASES

Abstract

Leiomyosarcoma of the stomach is a rare disease, and it's main metastatic forms are blood-borne metastasis and peritoneal dissem ination. Thus, the most common metastatic sites are the liver and peritoneum. However, resection of the liver for metastasis of this disease has rarely been reported. We present a patient with leiomyosarcoma of the stomach with liver metastasis who underwent total gastrectomy and liver resection twice for the metastasis. The patient was a 59-year-old woman who was admitted to a hospital associated with out university with gastric leiomyosarcoma and in whom liver metastasis was found in the lateral segment during total gastrectomy. She was readmitted to our clinic and underwent resection of the left lobe of the liver. Subsequently, she again developed a liver metastasis in S8 at 18 months after the resection of the liver and underwent a resection of that segment. Liver metastasis is considered to be an end-stage of cancer and has not been treated positively. However, the case presented here suggests that resection is the most effective treatment for liver metastasis of leiomyosarcoma of the stomach.
