Abstract：Objective: To investigate the expression and clinical significance of L1 cell adhesion molecule (L1CAM), melanoma nucleoprotein-18 (Mel-18) and proto oncogene (c-myc) in endometrial carcinoma. Methods: Endometrial carcinoma and paracancer tissue of 80 patients with endometrial cancer in Liaoning Provincial People's hospital from February 2015 to December 2019 were collected for clinical study. The expressions of L1CAM, Mel-18 and c-myc were detected by immunohistochemistry. The relationship between the expression of L1CAM, Mel-18, c-myc and clinicopathological parameters was analyzed. Pearson method was used to analyze the expression correlation of L1CAM, Mel-18 and c-myc. Results: The positive rates of L1CAM, Mel-18 and c-myc in endometrial carcinoma tissues were significantly higher than those in adjacent normal tissues (P<0.005).The expression of L1CAM, Mel-18 and c-myc protein in endometrial carcinoma tissues was correlated with lymph node metastasis and FIGO stage (P<0.05).L1CAM, Mel-18 and c-myc were positively correlated with each other (P<0.05). Conclusion: The positive rates of L1CAM, Mel-18 and c-myc in endometrial carcinoma are increased, and the expression of the three is positively correlated with each other. The expressions of L1CAM, Mel-18 and c-myc were correlated with lymph node metastasis and FIGO stage of endometrial carcinoma.
