Methods: Retrospective study of 7 patients with hepatic angiosarcoma. Results: Symptoms and signs such as abdominal pain were extremely nonspecific. The levels of the tumor markers were within the normal range. Four cases were positive for hepatitis B viruses. Among the 5 patients who received chemotherapy, improvement in survival was seen in 3 cases which also received surgery. Conclusion: Hepatic angiosarcoma is a rare and diffficult-to-diagnose malignant liver tumor. Surgery is the definitive treatment and adjuvant chemotherapy after surgery may improve survival.展开更多
