Key result
Primary hepatic angiosarcoma is associated with a very poor prognosis, with an overall 1-year survival rate of 12.8%, though women and patients under 60 undergoing surgery showed better survival.

What are the demographic features and prognostic factors for overall survival and disease-specific survival in patients with primary hepatic angiosarcoma?
Primary hepatic angiosarcoma has a very poor prognosis, but women and patients under 60 who undergo surgery have better survival outcomes.
Nomograms may refine PHA prognosis estimates; leaves open prospective validation before clinical adoption.
BACKGROUND: Primary hepatic angiosarcoma (PHA) is a rare malignant tumor. We explored the demographic features and prognostic factors of PHA. METHODS: We used the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) database to extract patients diagnosed with PHA from 1975 to 2016. We used the Kaplan-Meier method and Cox proportional hazards regression to evaluate the risk factors for overall survival (OS) and disease-specific survival (DSS). The nomograms were constructed and validated using the concordance index (C-index) and calibration plots. RESULTS: In total, 366 patients were included in this study. The disease onset was hidden, and most patients already had advanced disease when diagnosed. The prognosis of PHA was very poor, and the overall 6-month, 1-year and 2-year survival rates were 20.3%, 12.8% and 9.3%, respectively. Sex, age and surgery were all predictors of both OS and DSS in multivariate analysis. Women had better survival rates than men, and patients aged <60 years benefited from surgery in the multivariate models. The nomograms presented good accuracy, with C-index values of 0.679 and 0.665 for the OS and DSS prognostic models, respectively. The calibration plots showed good agreement between the nomogram predictions and actual observations. CONCLUSIONS: PHA has a poor prognosis. Regular physical examinations are essential for the elderly. Patients aged <60 years could benefit from surgery. We constructed accurate nomograms to predict survival that can greatly benefit clinicians.

Zeng et al. (2021) conducted a cohort in Primary hepatic angiosarcoma (PHA) (n=366). Surgery and demographic factors (age, sex) vs. No surgery / other demographic groups was evaluated on Overall survival (OS) and disease-specific survival (DSS). Primary hepatic angiosarcoma is associated with a very poor prognosis, with an overall 1-year survival rate of 12.8%, though women and patients under 60 undergoing surgery showed better survival.
