Abstract
Objective To observe the expression of mismatch repair gene proteins in endometrial complex hyperplasia. Methods A total of 50 pathological tumor specimens from patients with endometrial complex hyperplasia were collected. Immunohistochemical detection was performed on the pathological tissues. Clinical information was obtained from medical records for analysis. Results Among the 50 patients with endometrial complex hyperplasia, 27 cases (54%) showed deletion of at least one mismatch repair gene expression, 18 cases (36%) showed deletion of two or more mismatch repair gene expressions, and 3 cases (6%) showed negative expression of all four mismatch repair genes. Conclusion More comprehensive genetic testing should be performed for patients with endometrial complex hyperplasia, so as to provide an effective means for the prevention of endometrial carcinoma.
