[Liver cancer: diagnostic possibilities and value of pathology].

The high differentiation of treatment options for patients with liver carcinoma resulted in more extensive questions to the pathologist. Resection rate for HCC is about 30%, thus the multitude of diagnoses has to be made on biopsies. An histological (rarely cytological) diagnosis has to be the section specimens with regard to typing, grading, R classification and results of studies on molecular pathology of this tumor. Essential statements on resection specimens include pTNM classification, R classification, typing, and grading. Based on these data, more parameters expected to be of prognostic value can be evaluated.
