Abstract

PURPOSE
Intra-abdominal leiomyosarcoma is an uncommon malignant tumor, and its standard treatment is surgical resection. However, there is no generally preferred treatment for its metastatic mass, especially in the liver.
METHODS
According to the sarcoma registry, 476 patients were diagnosed as leiomyosarcoma and received treatment in Asan Medical Center, Seoul, Korea. And from 2003 to 2015, surgical resections of liver metastases were performed in 10 patients with leiomyosarcoma. The characteristics and short-term results were documented.
RESULTS
Of the 10 patients, the median age was 48 years and the median survival period was 34.2 months. The mean period from primary resection to liver metastasis was 12.9 months. Six patients had a single metastatic mass, and four had multiple nodules. One patient had an additional distant metastasis outside of the liver. Eight patients had a partial hepatectomy, and the others were treated using segmentectomy or lobectomy. Two patients (20%) died during follow-up. Four patients showed metastasis to other organs after surgical resection of the liver.
CONCLUSION
Intra-abdominal leiomyosarcoma with liver metastasis is a very rare disease. Long-term survival can be achieved after surgical resection and should be considered for all patients.
