Summary

Hepatic angiosarcoma (AS) is a rare, aggressive liver cancer. Early diagnosis and surgical resection offer the best treatment outcomes for this often fatal disease.

Area of Science:

  • Hepatology
  • Oncology
  • Pathology

Context:

  • Hepatic angiosarcoma (AS) is a rare primary liver tumor, accounting for 1-2% of all hepatic malignancies.
  • Its incidence is increasing due to associations with carcinogens like thorotrast and vinyl chloride.
  • AS is the most common primary mesenchymal tumor of the liver.

Purpose:

  • To present the epidemiological, clinical, diagnostic, and therapeutic characteristics of primary hepatic angiosarcoma.
  • To evaluate treatment outcomes and highlight the challenges in managing this aggressive cancer.

Summary:

  • Six patients with primary hepatic AS were analyzed, with no apparent predisposing factors in this cohort.
  • Symptoms and liver function tests were nonspecific at presentation.
  • Tumor characteristics included bilobar involvement (4/6), multifocality (2/6), and large median size (10.5 cm). Metastatic disease was present in 4 patients.
  • Treatment outcomes were poor: chemotherapy (VAC) for extrahepatic disease yielded a maximum survival of 8 months.
  • Liver transplantation for intrahepatic disease resulted in early recurrence and a maximum survival of 10 months.

Impact:

  • These findings underscore the aggressive nature of hepatic angiosarcoma.
  • Early diagnosis and radical surgical resection remain the most effective treatment strategies.
  • Further research is needed to improve therapeutic options for advanced disease.
