Aim. To study pathological and molecular features of liver metastases of colon adenocarcinoma. Material and methods. DNA mismatch repair (MMR), CXCR4 expression, Ki-67 proliferative activity were investigated in 125 cases of colon adenocarcinoma with liver metastases. First group consisted of 94 cases of tumor with liver metastases at diagnosis. The second group consisted of 31 cases with stage II disease at diagnosis, but subsequently these patient metastases. In second group KRAS mutation was investigated. The control group included 22 cases of stage II colon adenocarcinoma without disease progression. MMR was studied in 325 cases of colon adenocarcinoma without known stage. Results. MMR deficiency (dMMR) didn't revealed in group 1 and 2. The frequency of deficiency MMR in the general population of colon adenocarcinoma was 8%. Low level of expression of CXCR4 in group I and II was revealed in 16% of cases, in control group - in 73%. Low level of Ki-67 was revealed in 5% of cases of liver metastases (group 1 and 2), the frequency of KRAS mutations was 45%. Conclusion. Colon adenocarcinoma with liver metastases is characterized by aggressive immunophenotype: high expression rates CXCR4, Ki-67, and preferentially retained MMR function.
