研究外生型肝癌的临床分型。

复习1993~2008年国内有关外生型肝癌89例的文献资料和我院14例外生型肝癌的影像学资料，其中11例进行介入治疗。把外生型肝癌分为膈面型和脏面型，再根据肝叶分为左叶膈面型、左叶脏面型、右叶膈面型和右叶脏面型及尾状叶型，根据外生型肝癌肝内有无肿瘤分为单纯型M(-)和混合型M(+)，根据有无蒂分为带蒂型D(+)和无蒂型D(-)。

外生型肝癌可以生长在肝脏表面的任何部位：生长在肝脏脏面部位的比较多，为81例，占78.64%；而生长在肝脏膈面部位的仅为7例，占6.80%；尾状叶15例，占14.56%。外生型肝癌合并肝内病变占7.77%，外生型肝癌带蒂的占34.95%。

本研究对外生型肝癌的临床分型明确、容易掌握，对外生型肝癌的诊断、鉴别诊断、治疗有很大意义。

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.
