Abstract

Hepatocellular carcinoma (HCC) is a common type of cancer and has a high mortality rate. Based on the enhancement characteristics on imaging diagnostics combined with AFP concentration allows diagnosis of the disease. However, about 40% of tumors exhibit atypical enhancement, requiring biopsy for diagnosis. Percutaneous biopsy is a technique to take samples for testing in these cases. Purpose: Evaluate the results of percutaneous ultrasound-guided biopsy in diagnosing atypical hepatocellular carcinoma on computed tomography. Methods: Descriptive cross-sectional study on 27 patients with atypical enhancement images, underwent percutaneous ultrasound-guided biopsy and post-operative pathological diagnosis of HCC. Research at Thanh Hoa Oncology Hospital from January 2022 to April 2023. Results: There were 03 cases requiring a second biopsy (11.1%). The accuracy rate after the first biopsy was 88.9%, after the second biopsy it was 96.3%. In 90% of biopsy cases, 3 or more sample cores were taken and there was only 1 case of post-biopsy complications (hematoma under the liver capsule). Conclusion: Percutaneous ultrasound-guided biopsy is a highly accurate method, has very few complications, and is effective in diagnosing atypical HCC.
