Cost-effectiveness of non-invasive methods for assessment and monitoring of liver fibrosis and cirrhosis in patients with chronic liver disease: systematic review and economic evaluation

The study found that treating all patients with chronic hepatitis C without a prior non-invasive liver test (NILT) is cost-effective; however, recently approved interferon-free regimens were not included. For hepatitis B e antigen (HBeAg)-negative patients, this strategy is cost-effective only if the higher cost-effectiveness threshold is appropriate. For HBeAg-positive patients, two NILTs applied sequentially were cost-effective but highly uncertain. No conclusive results could be obtained for alcoholic and non-alcoholic fatty liver disease. Most studies evaluating non-invasive fibrosis tests had a high risk of bias.

Non-Invasive Diagnostic Assessment Tools for the Detection of Liver Fibrosis in Patients with Suspected Alcohol-Related Liver Disease: A Systematic Review and Economic Evaluation

Excessive alcohol consumption may lead to the development of alcoholrelated liver disease (ALD). Liver biopsy may be used in patients with suspected ALD to confirm the diagnosis, exclude other or additional liver pathologies, and provide accurate staging of the degree of liver injury in order to enable the prediction of prognosis and inform treatment decisions. However, as it is an invasive procedure that carries the risk of morbidity and mortality, current UK guidance recommends that biopsy is not required to confirm the diagnosis in patients with a high clinical suspicion of ALD in whom blood tests have excluded other causes of liver disease, unless it is necessary to confirm a diagnosis of acute alcoholic hepatitis in order to inform specific treatment decisions.

No evidence from randomised clinical trials for optimal management of patients with large bowel cancer spread to lymph glands draining the liver

Nearly a third of patients with large bowel cancers (colorectal cancer) spread to the liver (liver metastases) within five years of diagnosis of bowel cancer. The affected part of the liver can be removed surgically in a quarter of such patients who develop liver spread from bowel cancer. About a seventh of these patients, in whom the affected part of the liver is suitable for removal, develop cancer involvement of lymph glands draining the liver (hepatic lymph node). Such patients are associated with poor survival even after removal of the affected part of the liver and the involved nodes. This Cochrane review attempted to answer the question of whether removing the part of the liver is better than other forms of treatment (such as no treatment, chemotherapy, heat destructive therapy using radiofrequency waves, ie, radiofrequency ablation) in such patients but did not find any randomised clinical trial addressing the issue. Currently, there is no evidence from randomised clinical trials for optimal management of these patients. High quality randomised clinical trials are feasible and are necessary to determine the optimal management of patients with colorectal liver metastases with hepatic node involvement.

What happens during a biopsy?

A biopsy (taking a tissue sample) is one of the most commonly used medical tests. Tissue samples can be analyzed in order to find out, for instance, whether a suspicious lump is harmless or dangerous.

Transient elastography for measurement of liver fibrosis and cirrhosis in people with alcoholic liver disease

Liver fibrosis is a change in the microscopic structure of the liver because of liver inflammation. After many years of excessive alcohol consumption, liver fibrosis progresses to cirrhosis. Abstaining from alcohol may stop the fibrosis from further progression into significant or severe fibrosis and cirrhosis. The latter lead to complications of underlying diseases, including cancer.
