Introduction: the function of neuroendocrine peptides such as GLP-2 and its receptor has been associated with the development of colorectal carcinoma (CRC). This peptide promotes intestinal epithelial growth through the liberation of substances stimulating tumor cells, such as muscle fibroblasts, proliferation, migration and invasion, favoring CRC development. Objective: to analyze GLP-2 and GLP-2R amplification in tissue samples of patients diagnosed with CRC. Materials and Methods: paraffin embedded samples obtained from patients diagnosed with colon adenocarcinoma, between 2016 and 2020, at Hospital de San José and Infantíl Universitario de San José in Bogotá DC, evaluating GLP-2 and GLP-2R expression using the qPCR assay and immunohistochemistry.   Results: the study included a population of 50 patients diagnosed with CRC, 80% featured a classical moderately differentiated adenocarcinoma; qPCR testing showed GLP-2 and GLP-2R amplification in 4 samples (8%) of moderately differentiated adenocarcinomas. Conclusions: the relationship between GLP-2/GLP-2R expression and CRC remains unclear. Studies in animal models have reported that GLP-2 and GLP-2R expression are related to CRC development, while studies in humans, including the present study, have not demonstrated a direct relationship between GLP-2 and GLP-2R and the development of CRC.
