Abstract

Objective:

The incidence of endometrial hyperplasia & carcinoma is increasing in developing nations. Newer techniques are being tried to recognise endometrial hyperplasia. One of these is tumor suppressor gene phosphatase & tensin homologue (PTEN). It is frequently inactivated i.e turned off in endometrial hyperplasia lesions. This is an early event in endometrial tumorigenesis that may occur in response to known endocrine risk factors & offers an informative immunohistochemical marker for premalignant disease. The present study was planned to study PTEN immunohistochemical expression in endometrial hyperplasia.

Methods:

Women of >40 years of age presenting with abnormal uterine bleeding in the OPD of OBGYN Department of KG Medical University underwent endometrial biopsy. The histopathology of the biopsy tissue was done in department of Pathology of KG Medical University. The cases of endometrial hyperplasia were studied for PTEN immunohistochemical expression.

Results:

168 women of >40 years of age with abnormal uterine bleeding underwent endometrial biopsy. 50 women were diagnosed as endometrial hyperplasia. Of these, PTEN evaluation was done in 27 cases. Loss of PTEN expression was found in 11 cases (40.74%) of endometrial hyperplasia. Loss of PTEN expression was more in complex hyperplasia with atypia (66.66%) as compared to simple hyperplasia without atypia (29.4%).

Conclusion:

There is positive correlation between loss of PTEN expression and grade of morphological differentiation of hyperplasia.
