A liver metastasis is a malignant tumor in the liver that has spread from another organ that is affected by cancer. The liver is a common site for metastatic disease because of its rich, dual blood supply (the liver receives blood via the hepatic artery and portal vein). Metastatic tumors in the liver are 20 times more common than primary liver ...
Hepatic artery embolization, also known as trans-arterial embolization (TAE), is one of the several therapeutic methods to treat primary liver tumors or metastases to the liver. The embolization therapy can reduce the size of the tumor, and decrease the tumor's impact such its hormone production, effectively decreasing symptoms.
Previously, liver metastasectomy was limited to patients with less than four sites of metastasis in the liver, with a tumour-free margin of at least 1 centimetre, and no cancer elsewhere. [ 10 ] [ 11 ] These criteria have been challenged, however, and today the main criteria are a tumour-free margin and enough functional liver tissue (70% ...
The International Classification of Diseases for Oncology (ICD-O) is a domain-specific extension of the International Statistical Classification of Diseases and Related Health Problems for tumor diseases. This classification is widely used by cancer registries. It is currently in its third revision (ICD-O-3). ICD-10 includes a list of ...
Liver cancer can be primary in which the cancer starts in the liver, or it can be liver metastasis, or secondary, in which the cancer spreads from elsewhere in the body to the liver. Liver metastasis is the more common of the two liver cancers. [3] Instances of liver cancer are increasing globally. [8] [9]
Metastases to the liver can be treated by several types of hepatic artery treatments based on the observation that tumor cells get nearly all their nutrients from the hepatic artery, while the normal cells of the liver get about 70–80 percent of their nutrients and 50% their oxygen supply from the portal vein, and thus can survive with the ...

Although surgeons are able to remove parts of a single lymph node from the body to screen, it is impossible to remove every lymph node and other organs (lungs, liver, bones, etc.) to look for spread. [2] Doctors must assume that the tumor cells have likely spread to other regions of the body if micrometastases are present in one of the lymph nodes.
