[CEA determination in the follow-up of colorectal cancers].

CEA follow-up checks of 135 patients with colorectal carcinoma are described in a retrospective analysis. Unambiguous correlations were found to exist between clinical tumour staging and CEA findings in the context of both primary findings and recurrences and metastasation. Typical courses are described of 107 patients who received curative treatment. An assessment is made of the value of CEA determination in postoperative follow-up.
