As presented in Table 1, no significant association was observed between the miR-548t-5p expression levels and sex, age, tumor location, N stage, or serum carcinoembryonic antigen (CEA), but the miR-548t-5p expression levels did correlate negatively with the T stage, nerve infiltration, and serum CA199 values (p = 0.024, p = 0.024, and p = 0.001, respectively). The gene discussed is CEACAM5; the disease is neoplasm.
