Colorectal tumors were studied 5 months after carcinogen injection to outbred albino rats with secondary immunodeficiency by common histological and immunobiochemical methods with the use of monoclonal and polyclonal antibodies to Ki-67, Bcl-2, p53, and VEGF. Injection of carcinogen to intact animals led to the formation of adenocarcinomas with high and moderate cell differentiation in the colon, while injection of carcinogen to animals with immunodeficiency was associated with a 1.5-fold higher incidence of GRADE 2 and GRADE 3 adenocarcinomas with more aggressive morphological phenotype and appearance of distant metastases.
