Abstract
Introduction: Study was planned to investigate PTEN gene expression in endometrial hyperplasia and carcinoma as analyzed by immunohistochemistry. Material and Method: This study was conducted on 80 endometrial samples in the Department of Pathology, Gandhi Medical College, Bhopal (January 2012 to August 2016) Results: 5 out of 5 cases of proliferative endometrium, 3 out of 5 cases of secretory endometrium, 37 [84%] out of 44 cases of simple and complex endometrial hyperplasia without atypia, 8 out of 15 cases of simple and complex endometrial hyperplasia with atypia and 3 out of 11 cases of endometrial carcinoma showed positive PTEN expression. Conclusion: PTEN is a major gene involved in the pathogenesis of endometrial carcinoma. Our data suggest that decreased PTEN expression was a marker of earliest endometrial pre-cancer lesion and we propose that use of PTEN immunostaining in a clinical setting may be informative in identifying premalignant lesions that are likely to progress to carcinoma.
