Summary
Management of hepatic adenomas should be individualized. Smaller tumors (<5 cm) can be observed, while larger ones (>5 cm) may require resection due to malignancy risk. Hepatic arterial embolization is a new approach for hemorrhage.
Area of Science:
- Hepatology
- Surgical Oncology
- Radiology
Background:
- Hepatic adenomas are uncommon liver neoplasms.
- Diagnosis can occur due to hemorrhage or incidental findings.
- Malignant transformation incidence and optimal treatment remain unclear.
Purpose of the Study:
- To review a 10-year experience in managing hepatic adenomas.
- To evaluate treatment strategies based on tumor size and presentation.
- To assess the risk of malignant transformation.
Main Methods:
- Retrospective review of 12 patients with hepatic adenomas.
- Analysis of patient demographics, tumor characteristics, and treatment outcomes.
- Correlation of oral contraceptive use with diagnosis.
Main Results:
- Nine of 10 adult females used hormonal preparations.
- Four small tumors (1.0-4.0 cm) were managed with observation after stopping oral contraceptives.
- Four larger tumors (5.5-13 cm) underwent resection, with three showing malignant transformation.
- Four patients with acute hemorrhage were treated with hepatic arterial embolization.
Conclusions:
- Individualized management of hepatic adenomas is crucial.
- Observation is suitable for lesions <5 cm with normal Alpha-fetoprotein levels.
- Surgical resection is recommended for lesions >5 cm due to malignancy risk.
- Hepatic arterial embolization is a viable option for acute hemorrhage.
