Currently, if the hepatic adenoma is >5 cm, increasing in size, symptomatic lesions, has molecular markers associated with HCC transformation, rising level of liver tumor markers such as alpha fetoprotein, the patient is a male, or has a glycogen storage disorder, the adenoma is recommended to be surgically removed.

A similar procedure is transarterial embolization but without chemotherapeutic agents injection, used in the treatment of hypervascular liver metastases. These therapies are based on the predominantly arterial vasculature of HCC and hypervascular metastases, while the remaining liver parenchyma has a dual vascular intake, predominantly portal.
Hepatocellular carcinoma (HCC [1]) is the most common type of primary liver cancer in adults and is currently the most common cause of death in people with cirrhosis. [2] HCC is the third leading cause of cancer-related deaths worldwide.
Cholangiocarcinoma can be detected with these commonly used tumor markers: carbohydrate antigen 19-9 (CA 19–9), carcinoembryonic antigen (CEA) and cancer antigen 125 . These tumor markers are found in primary liver cancers, as well as in other cancers and certain other disorders. [53] [54]
The radiation sensitivity of the liver parenchyma limits the radiation dose that can be delivered via external beam radiotherapy. SIRT, on the other hand, involves the direct insertion of radioactive microspheres to a region, resulting in a local and targeted deposition of radioactive dose. It is therefore well-suited for treatment of liver tumors.
Hepatocellular carcinoma is the most common primary liver cancer, and the most common cause of death in people with cirrhosis. [153] Screening using an ultrasound with or without cancer markers such as alpha-fetoprotein can detect this cancer and is often carried out for early signs which has been shown to improve outcomes. [2] [154]
The liver is responsible for the production of the vast majority of coagulation factors. In patients with liver disease, international normalized ratio (INR) can be used as a marker of liver synthetic function as it includes factor VII, which has the shortest half life (2–6 hours) of all coagulation factors measured in INR. An elevated INR in ...
Transarterial bland embolization (TAE, also known as HAE) is a catheter-based tumor treatment of the liver.In this procedure, embolizing agents (e.g., polyvinyl alcohol, gelfoam, acrylic copolymer gelatin particles, embospheres) can be delivered through the tumor's feeding artery in order to completely occlude the tumor's blood supply.
