Background: Primary malignant vascular tumors of the liver are rare, aggressive and poorly understood subtypes of liver cancers. In this analysis, we aim to determine the impact of tumor histology and other socio economic factors on survival of these tumors and hepatocellular carcinomas. Methods: Patients with malignant histopathological diagnoses of hepatocellular carcinoma not otherwise specified (HCC NOS), hepatocellular carcinoma with spindle cell (HCC SP), fibrolamellar (HCC F), clear cell (HCC CL), scirrhous (HCC SC) and pleomorphic variants ( HCC PL), combined hepatocellular carcinoma and cholangiocarcinoma (Mixed), hepatic angiosarcoma (AS), hemangioendothelioma (HE), its epithelioid variant (EHE) and hemangiopericytoma (HP) were identified using the SEER (version 2018) database. Overall survival was studied with Kaplan–Meier with the log rank method. Multivariable analysis was performed to assess the impact of race, ethnicity, marital and insurance status on survival of these patients. Results: We analyzed de-identified data of 104502 patients from the year 1973 to 2016 with hepatocellular carcinomas and malignant vascular tumors of liver (including 101851 patients with HCCNOS, 70 with HCC SP, 378 with HCC F, 104 with HCC SC, 593 with HCC CL, 23 with HCC PL, 950 with Mixed, 367 with AS, 36 with HE, 120 with EHE and 10 with HP ) respectively. Median overall survival (OS) of HCC NOS was calculated to be 7 months. Among hepatocellular carcinoma patients HCC F had the longest median OS of 29 months and HCC SP had the shortest median OS of 3months (P < 0.001). Additionally, among patients with malignant vascular tumors, AS had the shortest median OS (1 month) while patients with EHE had the longest median OS of 81 months (P < 0.001). Overall, married and insured patients had a better overall survival than unmarried and uninsured patients (P < 0.04). Conclusions: Malignant vascular tumors of liver are rare in comparison to hepatocellular carcinomas. Spindle cell variant of HCC and liver angiosarcomas carry the worst prognosis and fibrolamellar variant of HCC, hemangioendothelioma (HE) and its epithelioid variant (EHE) have the best prognosis. Insurance and marital status has a positive impact on overall survival of liver cancer patients.
