Assessment of Endometrial Carcinoma Markers and Hormone Receptors Profile before and after Bariatric Surgery: A Clinico-Pathological-Immunohistochemical Study

Abstract

Background: Obesity is a major risk factor for endometrial carcinoma, and we aim to assess markers of carcinogenesis including PTEN and Ki-67 and hormone receptors profile including ER, PR and AR before and after bariatric surgery to find out its effects in reducing endometrial carcinoma risk in morbid obese females. Patients and methods: The study included 80 females with morbid obesity (BMI > 40 Kg/m 2) who underwent bariatric surgery. All were sampled by Pipelle biopsy at baseline and 12 months after operation and examined histopathologically and immunohistochemically for Ki-67, PTEN, ER, PR and AR. Results: Sixty two out of 80 (62/80) females showed no pathological abnormalities; 4 had polyps; 7 had simple endometrial hyperplasia; 4 had atypical endometrial hyperplasia and 3 had endometrial carcinoma. In total, 34 females underwent gastric bypass operation (42.5%) and 46 underwent a sleeve gastrectomy operation (57.5%). There was a statistically significant difference between baseline weight and BMI before and after surgery (p < 0.001). Of the 7 women with simple hyperplasia, resolution occurred in 5 within 7 months of surgery. Three of 4 females with atypical hyperplasia (AH) showed resolution after 9 months. Mean Ki-67 score was lower at 12
