Introduction : Primary hepatic sarcoma is rare disease with higher recurrence after surgical treatment. This study analyzed outcomes after surgical resection of patients with primary hepatic sarcoma.

Methods : From 2001 august to 2016 september, 11 patients were pathologically diagnosed after surgical resection as hepatic sarcoma. Patient characteristics and tumor characteristics, treatment, tumor recurrence and patient survival were analyzed.

Results : All patient except 1 was surgically treated with R0 resection. Mean follow up duration was 711 days after surgical resection. Among 11 patients, 5 patients were diagnosed as angiosarcoma, 3 were undifferentiated sarcoma, 1 was biliary cystadenocarcinoma, 1 was embryonal sarcoma and 1 was carcinosarcoma. Mean tumor size was 12.4cm and median tumor number was 1. All patients had recurrence and mean time to recurrence was 282 days. 9 patients get tumor recurrence within 1 years after surgery. These 9 patients are all expired due to cancer recurrence. Only 2 patients (18.2%) are still alive. 1 patient with angiosarcoma received central haptatectomy and got recurrence on liver segment 4 at 5 years later. RFA was done on S4 and he got no recurrence for 6 years. 1 patient with embryonal sarcoma received Rt. hemihepatectomy and got recurrence at abdominal wall at 1 year and 4 months later. After surgical resection and survive for 1 year without recurrence.

Conclusions : Primary hepatic sarcoma has very poor outcome even after proper surgical resection. As known before, only embryonal sarcoma has better outcome, relatively.
