Survival disparities among racial groups with hepatic malignant tumors.

Abstract

Investigating the impact of race on the clinicopathologic characteristics and prognosis of hepatic malignant tumors represents a complex and significant area of research. Notably, distinct differences exist among various racial groups in terms of the clinical manifestations, pathologic features, and prognosis of hepatic malignant tumors. To explore the effect of race on clinicopathologic features and prognosis of hepatic malignancies. Data from patients with hepatic malignancies diagnosed between 2000 and 2019 were collected from the Surveillance, Epidemiology, and End Results database and statistically analyzed. This study included 123558 patients with hepatic malignant tumors, among whom 21078 (17.06%) were Asian, 14810 (11.99%) were Black, and 87670 (70.95%) were white. The median survival times for patients with hepatic malignant tumors of different races were 12.56, 7.70, and 9.35 months for Asian patients, Black patients, and white patients, respectively. The 3-year survival rates for Asian, Black, and white patients were 29%, 19%, and 21%, respectively, and the 5-year survival rates were 22%, 13%, and 15%, respectively. The Kruskal-Wallis test indicated a significant difference in the survival time of patients with hepatic malignant tumors between different races (P < 0.001). Univariate analysis revealed gender disparities in the prognosis among different ethnic groups (Asian: P > 0.05; Black: P < 0.001; White: P < 0.05). Among Black patients, the prognosis was less affected by the degree of hepatic fibrosis than among Asian patients and white patients (Black patients: P < 0.05; Asian patients: P < 0.001; White patients: P < 0.001). Significant differences were observed in the median survival time among patients with hepatic neuroendocrine tumors and hepatoblastomas during pathologic staging between races. Tumor number was inversely related to the prognosis. Cox regression analyses revealed that T stage, M stage, surgery, chemotherapy, alpha-fetoprotein, and tumor size independently influenced prognosis. Age was a specific independent prognostic factor for white patients. Among the tumor stages, N stage is a self-reliant prognostic element specific to white patients. Conversely, radiotherapy and liver fibrosis were not self-reliant prognostic factors for Black patients. Income alone did not independently influence the prognosis of Asian patients. The prognosis of hepatic malignant tumors is better among Asian patients than among Black patients. The prognosis of hepatic malignant tumors among white patients is affected by multiple factors, including age and N stage.
