Clinical diagnosis and treatment of metastatic liver leiomyosarcoma in 5 cases / 中华普通外科杂志

ABSTRACT

Objective:To investigate the clinical features, treatment methods of metastatic liver leiomyosarcoma (MLL).Methods:The characteristics of 5 cases of MLL were reviewed and summarized. Among them, 4 cases were derived from retroperitoneal leiomyosarcoma and 1 case was derived from uterine leiomyosarcoma. In terms of metastasis time, 1 case was simultaneous liver metastasis and 4 cases were heterochronous liver metastases, all of which were more than 2 years away from the primary tumor resection.Results:One patient died within 2 years after the diagnosis of MLL, and this patient had not undergone surgical treatment for liver metastases. Of the 4 patients who had had the metastasis resection, 2 patients died within 3 years. Currently, 2 patients are alive, 1 patient after 36 months, and 1 patient after 29 months.Conclusion:MLL occurs mostly years after the primary tumor is removed. Currently, surgical treatment is considered to be the main treatment method for MLL, which can significantly prolong the patients survival.
