As presented in Table 1, no significant disparities were observed in gender, alcohol consumption history, hemoglobin levels, leukocyte count, creatinine levels, alanine aminotransferase (ALT), aspartate aminotransferase (AST), carcinoembryonic antigen (CEA), cytokeratin 19 fragments (CYFRA211), and neuron-specific enolase (NSE) between the ADC patients with diabetes and the control group. This evidence concerns the gene CEACAM5 and diabetes mellitus.
