in 98 patients affected by colorectal cancer ( 43 patients with colon cancer , 55 patients with rectosigmoid cancer ) the specificity of some tumor markers ( cea , gica , tpa , alpha-fp , fpa , gamma-gt ) has been tested in evidencing the coexistence of liver metastases and the site of the primary tumor , i.e . the rectosigmoid region ( rectum + 15 cm of the adjacent sigmoid colon ) vs the rest of the colon .
