Liver tumors (also known as hepatic tumors) are abnormal growth of liver cells on or in the liver. Several distinct types of tumors can develop in the liver because the liver is made up of various cell types. [1] Liver tumors can be classified as benign (non-cancerous) or malignant (cancerous) growths.
Benign liver tumors generally develop on normal or fatty liver, are single or multiple (generally paucilocular), have distinct delineation, with increased echogenity (hemangiomas, benign focal nodular hyperplasia) or absent, with posterior acoustic enhancement effect (cysts), have distinct delineation (hydatid cyst), lack of vascularization or show a characteristic circulatory pattern ...
In 2003, Yao et al. reported experience at the University of California San Francisco five-year post-transplantation survival of 75% in patients with tumors as large as 6.5 cm, or up to three lesions each less than 4.5 cm with cumulative tumor burden ≤8 cm. [4] Additional studies using these so-called "UCSF criteria" have shown favorable post ...
As with any cancer, the treatment and prognosis of HCC varies depending on tumor histology, size, how far the cancer has spread, and overall health of the person. The vast majority of HCC cases and the lowest survival rates after treatment occur in Asia and sub-Saharan Africa , in countries where hepatitis B infection is endemic and many are ...
Estimates based on most recent data suggest that each year there are 841,000 new liver cancer diagnoses and 782,000 deaths across the globe. [55] Liver cancer is the most common cancer in Egypt, the Gambia, Guinea, Mongolia, Cambodia, and Vietnam. [55] In terms of gender breakdown, globally liver cancer is more common in men than in women. [43 ...
Focal nodular hyperplasia is a benign tumor of the liver (hepatic tumor), which is the second most prevalent tumor of the liver after hepatic hemangioma. [1] It is usually asymptomatic, rarely grows or bleeds, and has no malignant potential. [2]
Adenomas are benign tumors of gland-forming cells, and are usually specified further by their cell or organ of origin, as in hepatic adenoma (a benign tumor of hepatocytes, or liver cells). Teratomas contain many cell types such as skin, nerve, brain and thyroid, among others, because they are derived from germ cells. [ 36 ]
Radiation therapy is used to kill cancer cells; however, normal cells are also damaged in the process. Currently, therapeutic doses of radiation can be targeted to tumors with great accuracy using linear accelerators in radiation oncology; however, when irradiating using external beam radiotherapy, the beam will always need to travel through healthy tissue, and the normal liver tissue is very ...
