Our study showed that both CK7 and CK20 were present in different tumor areas and tumor gradings, MMP9 was more constantly expressed compared to the more variable expression of MMPs 2 and 8, vascular densities did not seem to increase in high-grade invasive tumors compared to low-grade tumors.

We examined tumor drainage blood from 197 patients with Dukes' stage B and C CRC.
