A Retrospective Analysis of Clinical Characteristics, Treatment Modalities and Outcome of the Patients With Infantile Hepatic Hemangiomas: Single-center Experience From Turkey.

ABSTRACT

OBJECTIVE: Hepatic hemangiomas (HH) are the most common vascular tumors of the liver. It is important to distinguish hemangiomas from malignant liver tumors. MATERIALS AND METHODS: The patients 0 to 1 years old, were diagnosed with HH and followed up in the oncology outpatient clinic between 2009 and 2020 were included in the study. RESULTS: A total of 127 patients with the diagnosis of HH were included in the study. Of the patients, 99 (78%) had focal, 20 (15.7%) had multifocal, and 8 (6.3%) had diffuse HHs. Surgery was performed and the diagnosis was confirmed histopathologically in 6 patients (4.7%). During the follow-up, 16 (12.5%) patients received medical treatment. Thirteen (10.2%) were treated with propranolol, 2 (1.5%) with corticosteroids, and 1 (0.8%) with propranolol and corticosteroids. Complete response was obtained in 9 (9/16) patients and partial response was obtained in 6 (6/16) patients with medical treatment. CONCLUSION: Although HH is a benign tumor, it is important to make its differential diagnosis with malignant tumors of the liver. Over the years, the need for histopathologic examination for diagnosis has decreased. The success rate of propranolol is high, and the need for other treatment options with a high side-effect profile has decreased significantly since 2008.
