In a cohort of 57 patients, with a mean follow-up time of 30.9 months, higher levels of carcinoembryonic antigen and lymphocyte-to-monocyte ratio were linked to worse survival, while higher neutrophil-to-lymphocyte ratio levels and left-sided primary colon cancer were positive prognostic factors. Here, CEACAM5 is linked to malignant colon neoplasm.
