Apart from that, in both HCC and CCC, no significant correlation was seen between SSTR or CXCR4 expression intensities or positivity of the tumor cells and TNM classification, staging or grading of the tumors, presence or absence of cirrhosis or of vascular infiltration, presence of a solitary tumor or of multiple lesions, height of ASAT, ALAT or GGT serum values or of the tumor markers alpha fetoprotein (AFP) and CA19–9. This evidence concerns the gene CXCR4 and hepatocellular carcinoma.
