Surgical treatment outcomes of primary hepatic sarcomas: A single-center experience

Figure 1 Flow chart of selecting pure hepatic sarcoma. 5 cases of angiosarcoma and 4 cases of undifferentiated sarcoma were included. HCC: Hepatocellular carcinoma; CCC: Cholangiocellular carcinoma.

Figure 2 Images of a surviving patient (cases 7 and 8). A: Case 7. Left: T1 magnetic resonance imaging (MRI) of pre-operative angiosarcoma on S8 (orange circle). Right: T2 MRI of recurrence on S2 five years after central hepatectomy; B: Case 8. Left: MRI of pre-operative sarcoma. An 11.5 cm circumscribed mass with hemorrhage on the Rt. lobe. Right: Positron emission tomography-computed tomography of the recurrent mass. Focal fluoro-deoxyglucose uptake at the Rt. anterior abdominal wall.

Figure 3 Disease-free survival. Median disease-free survival was 52 d. There was no statistical difference between angiosarcoma and undifferentiated sarcoma groups.

Figure 4 Overall survival. The 5-year survival rate was 29.6%. There was no significant difference between survival of the angiosarcoma and undifferentiated sarcoma groups.

Figure 5 Overall survival depending on adjuvant therapies. Patients who received adjuvant therapy showed higher overall survival rate.
