In BMC Cancer this week, a team of researchers in China compare the usefulness of serum golgi protein 73 and alpha-fetoprotein as biomarkers for hepatocellular carcinoma. The team conducted a review of the available literature, and found that GP73 and AFP were of comparable accuracy, sensitivity, and specificity in diagnosing hepatocellular carcinoma. However, the researchers add, more study is needed to determine the diagnostic utility of GP73 in combination with AFP.
