To study clinical classification of extrahepatic growing hepatocellular carcinoma.

Image data of 14 cases about EGHC, 11 of which about interventional treatment, literature data of 89 cases about EGHC in China from 1993 to 2008 were reviewed. Classification: Extrahepatic growing hepatocellular carcinoma is firstly divided into diaphragmatic surface and visceral surface, and then according to lobes of liver, further divided into left lobe diaphragmatic surface and left lobe visceral surface, right lobe diaphragmatic surface, right lobe visceral surface and caudate lobe. Besides, according to whether there was tumor or not, they also were divided into simple form M(-) and mixed phase M(+). Furthermore, according to whether there is pedicel, it has got the type without pedicel D(-) and the type with pedicel D(+).

EGHC can occur anywhere on the surface of lever: 78.64% of the cases or 81 cases on the visceral surface, only 6.80% (7 cases)on the diaphragmatic surface, 14.56% 15(cases) on caudate lobe, 7.77% about the incorporation of EGHC and pathological changes within lever, and 34.95% about the EGHC with pedicel.

This study has a definite clinical classification on EGHC, which is easy to grasp. So it is profoundly significant for the diagnosis, differential diagnosis and treatment of EGHC.
