Hepatocellular Carcinoma: Sensitivity and Specificity

Introduction: Hepatocellular carcinoma often occurs in cirrhotics, though patients with Hepatitis C may develop HCC without Cirrhosis.

Prevalence

The sensitivity and specificity of findings for Hepatocellular Carcinoma are listed below. See the left navigation bar to change the display.

Pre-Test Probability (Prevalence): %.	Post-Test Probability (Predictive Value): %.	Switch to display mode.
Note that calculating probabilities from more than one** finding is inherently inaccurate because findings are not independent. (For example, using two positive findings that share a common pathogenesis is likely to overestimate the true probability.)
