METAVIR Fibrosis Stage F4
METAVIR fibrosis stage F4 indicates cirrhosis on the METAVIR histologic fibrosis scale. [1]
METAVIR Fibrosis Staging Context
METAVIR fibrosis stages range from F0 through F4, where higher stages reflect more advanced fibrosis. [1] Stage F3 and stage F4 are often grouped as “significant fibrosis” in clinical research. [2]
Clinical Meaning of F4 (Cirrhosis)
Cirrhosis represents advanced liver scarring that is associated with major long-term complications of chronic liver disease. [1]
Confirmation With the Testing Method
Liver biopsy is the histologic reference method used to assign METAVIR stages. [2] Noninvasive staging methods such as transient elastography may be reported as METAVIR-equivalent categories, where F4 corresponds to the cirrhosis range in that reporting scheme. [1]
Implications for Care Planning
F4 (cirrhosis) generally triggers management focused on complications of cirrhosis risk reduction and ongoing surveillance for liver-related outcomes. [1]
Practical Interpretation Notes
Transient elastography–derived METAVIR categories can show measurement-to-measurement discordance in some patients, so clinical staging should be interpreted in context of the entire evaluation. [1]
