Diagnostic Strategies and Treatment of Liver Tumors
Yoshiharu Tokimitsu and Yukihiro Shimizu
Abstract
Because liver tumors are usually asymptomatic, they are frequently observed incidentally on imaging tests performed for other purposes. The most common types of liver tumors are cysts and hemangiomas, which do not require any treatment unless they are accompanied by infection, hemorrhage, or rupture. In contrast, primary liver cancer and metastatic liver tumors are usually found in patients at high risk during regular checkups or close examination. Other benign masses found in the liver often need CT, MRI, or even liver biopsy for a final diagnosis. Radiofrequency ablation has been shown effective in the treatment of hepatocellular carcinomas and liver metastases from colorectal cancer, with liver resection also effective for those tumors.
