The performed comparative analysis for the routine marker (CEA) and CRP (Table 7) additionally confirms the usefulness of CXCL14 and suggests the need to continue research on this parameter and its use in the diagnosis of CRC, as the values of the obtained diagnostic criteria indicate greater usefulness of simultaneous CXCL14 and CRP determinations. The gene discussed is CXCL14; the disease is colorectal carcinoma.
