In this manuscript, we have extensively examined expression and prognosis of CXCL1 gene in colorectal adenocarcinoma (COAD) using different cases of colorectal adenocarcinoma and tissues. To verify this, protein and mRNA expressions of cxcll were identified through RT-PCR and immunohistochemistry in 30 cases of colorectal adenocarcinoma and adjacent tissues, which were surgically resected from January to July 2021 in our hospital, and relationship between CXCL1 mRNA and clinico-pathological features and protein expression was analyzed. CXCL 1 mRNA in COAD carcinoma’s expression was considerably higher than in the adjacent normal intestine. At the same time, CXCL 1 diagnostic receiver operating characteristic (ROC) curve had preferably higher value of the diagnostic for area under curve (AUC) = 0.912, 95%, COAD (P < 0.001, CI = 0.825-0.969). We have observed that CXCL1 gene was closely linked with preoperative CEA level (P = 0.007) and gross tumor typing (P = 0.039). Finally, we have concluded that that CXCL1 can be a possible biomarker for stress prognosis and diagnosis.
