Successful treatment with pazopanib plus PD-1 inhibitor and RAK cells for advanced primary hepatic angiosarcoma: a case report.

Background: Primary hepatic angiosarcoma (PHA) is a rare and aggressive solid tumor, with high rates of local recurrence and distant metastasis, and poor prognosis. There are no established treatment guidelines for PHA.

Case Presentation: A 78-year-old asymptomatic man with PHA that was successfully treated with pazopanib plus PD-1 inhibitor and RetroNectin-activated killer cells (RAK cells). After one month of treatment, there was a clear reduction in the size and number of the liver metastases; and after nearly 15 months, most of the lesions were stable, no new lesions had developed, and the side effect of treatment was minor.

Conclusion: Pazopanib, PD-1 inhibitor and RAK cells could serve as a potential option for the treatment of advanced PHA.
