WebChromogranin and synaptophysin are expressed in 83% and 94% of these tumors, respectively. CD56 and NSE are also typically positive. Wide-spectrum cytokeratin is positive, characteristically in a perinuclear dot-like fashion. It is important to note that carcinoids are typically negative for CK7 and epithelial membrane antigen (EMA). WebElevated serum levels of chromogranin A were found in 32 of 79 patients (43%). Levels over 600 ng/ml were present in 7 of 76 patients (9.2%), all of whom had very high serum levels of alpha-fetoprotein. Hence, elevated serum levels of chromogranin A are present in over one third of patients with hepatocellular carcinoma.
