[Classification and documentation of liver metastases of colorectal carcinomas]

Today, there is a variety of therapy modalities for patients with liver metastases. This therapeutic spectrum has made a more accurate classification of liver metastasis necessary. Data concerning therapy have to be documented as well as pretherapeutic data and data concerning results of pathologic examination. Without a careful documentation a reliable comparison between different therapy modalities will be impossible and thus a generally accepted concept of liver metastasis therapy cannot be expected. A classification of liver metastasis thus required should aid in the planning of treatment, yield an indication of prognosis, and assist in the evaluation of the results of treatment.
