Real-world data on the clinicopathological traits and outcomes of hospitalized liver hemangioma patients: a multicenter study.

backgroundThere is currently a lack of consensus regarding the clinical features, diagnosis, treatment indications and options, and risk assessment of hepatic hemangioma patients.

methodsThis was a multicenter, real-world study that analyzed a large number of hepatic hemangioma cases in China and included patient data on epidemiology, diagnosis, treatment methods, and outcomes.

resultsA total of 5,143 patients hospitalized for hepatic hemangioma were included, of whom 34.42% were male and 65.58% were female. The age distribution was concentrated between 30 and 60 years old, accounting for 87.41% of the patients. Among the hepatic hemangioma patients, 60.8% had only one tumor, with the most common pathological type being cavernous hemangioma (96.07% of cases). The treatment motivations and indications included anxiety, obvious clinical symptoms, rapid tumor growth, unclear diagnoses and acute emergencies. Overall, 41.4% of the patients were treated for psychological reasons, while 30.59% were treated because they presented obvious (primarily nonspecific) clinical symptoms. Hepatic resection was the main therapeutic method and was based on various indications. There were a small number of patients with Kasabach-Merritt syndrome, according to its generally recognized definition.

conclusionsMost patients in this study who were hospitalized for hepatic hemangioma did not meet the indications for requiring treatment. Surveillance is the recommended course of action for definitively diagnosed hepatic hemangioma, and a new classification system is needed to standardize the diagnosis of this condition.
