hyperplastic polyps were combined with tubular adenomas as polyps with none or the lowest potential for malignancy. Polyps with dominantly villous growth pattern or polyps with high grade dysplasia (as those with the highest potential for malignancy) were, in turn, combined with three cases of adeno...
Interestingly, cells of the tumor microenvironment in adenomas showed higher expression of CD133, which may indicate their special role in the development of the tumor process. It was also found that in samples of colorectal cancer metastases, the levels of the cytoplasmic and nuclear expression of...
