Multimodal treatments of right gastroepiploic arterial leiomyosarcoma with hepatic metastasis:A case report and review of the literature

摘要

Leiomyosarcoma of an artery is very rare,and cases with hepatic metastasis are even rarer.We describe a case of a 70-year-old man who after follow up due to rectal cancer,presented with an intra-abdominal hypervascular mass and a hepatic mass.After surgical resection,it was diagnosed as a leiomyosarcoma of the right gastroepiploic artery with hepatic metastasis.Multiple metastases had recurred at the liver.He has survived more than 53 mo through multimodal treatments(three surgical resections,radiofrequency ablation,transarterial chemoembolization,chemotherapies,and targeted therapy).Multimodal treatments,including active surgical resection,may be helpful in the treatment of aggressive diseases such as arterial leiomyosarcoma with metastasis.
