| Popis: | Colorectal cancer is the third most common cancer worldwide and the second cause of death from malignant tumors. Colorectal cancers are treated with surgery, chemotherapy, gene therapy and immunotherapy. PD-1 and PD-L1 proteins have recently been considered as potential targets of anticancer therapy in colorectal cancer. The aim of this study was to evaluate the association of immunohistochemical expression of PD-1 and PD-L1 proteins in colorectal cancer patients with selected clinical and morphological parameters and their survival. Ninety-eight cases of colorectal cancer were studied. Immunohistochemistry was used to evaluate the expression of PD-1 and PD-L1 proteins. Correlations were found between the expression of PD-L1 protein in lymphocytes and lack of lymph node metastases and a lower clinical stage. There was also a correlation between PD-L1 protein expression in cancer cells and a higher grade of histological malignancy. |
