We aimed to investigate if expressions of survivin and p27 proteins are involved in the development of endometrioid carcinoma, along with whether there are any correlations between these proteins and loss of wild-type PTEN that is found in up to 80% of endometrial carcinomas. We also studied their correlations with classical prognostic factors and survival in endometrial carcinoma. To our knowledge, this is the first time survivin expression is investigated in endometrial hyperplasia along with endometrioid adenocarcinoma. For immunohistochemical analysis, 29 endometrioid adenocarcinoma, 38 endometrial hyperplasia, and 10 proliferative endometrium tissue samples were selected in the pathology archives. Staining of cells was scored as +2 if >50%, +1 if <50%, and negative if none were stained positive. Survivin expression increased from proliferative to hyperplasia to carcinoma cases. PTEN and p27 expressions decreased in hyperplasia and carcinoma cases with respect to proliferative endometrium. All these differences were statistically significant (P < 0.05). PTEN positively correlated to p27 (P < 0.05); however, neither was correlated with survivin. None of these genes were correlated with classical prognostic factors such as grade and myometrial invasion in endometrioid adenocarcinoma. However, mean survival was statistically significantly higher in PTEN-positive cases (46.6 vs 16.4 months) (P < 0.05). Survivin overexpression might be one of the important mechanisms in the development of endometrioid adenocarcinoma along with lost or decreased activity of PTEN and p27. However, survivin seems to exert its role in ways different from those of PTEN or p27 in the development of endometrioid adenocarcinoma. These findings on the role of survivin in endometrioid adenocarcinoma should be confirmed and the pathways through which survivin acts in endometrioid adenocarcinoma studied further with a larger sample size.

Background: Abnormal uterine bleeding (AUB) is one of the most commonly encountered gynecological problem and almost 33 % of women in gynecological outpatient department presented with abnormal uterine bleeding. Dilatation and curettage (D and C) have been the main diagnostic procedure in the evaluation of abnormal uterine bleeding patients for decades. The objective of the present study was to analyze the different types of endometrial histopathology of patients presented with the abnormal uterine bleeding and its correlation with the different types of abnormal uterine bleedingMethods: This is a retrospective study, conducted in a medical college in the Department of Obstetrics and Gynecology over a period of one year from June ’17 to June ’18. All cases of AUB more than 35 years of the age group who underwent D and C procedure were included in this study. Total 100 patients were analyzed.Results: Total 100 patients were analyzed. Age group ranges from 35-58 years and most common age group presenting with AUB was 35-39 years. The most common presenting complaint was menorrhagia 54% (54/100). Histopathology of endometrium showed non-organic causes in 80% (80/100) of AUB patients and the remaining 20% (20/100) had organic causes. Most common endometrial histopathology among non-organic causes was proliferative endometrium 43.75% (35/80) and the most common organic cause was endometrial polyp 40% (8/20). Endometrial hyperplasia was found in 30% (6/20) and endometrial carcinoma was found in 20% (4/20) of cases among organic causes.Conclusions: D and C is the useful and the cost-effective diagnostic procedure in the evaluation of AUB. Histopathological evaluation of endometrial samples is especially indicated in AUB patients to rule out carcinoma and preneoplastic conditions as histopathology is 100% diagnostic in cases of endometrial hyperplasia and carcinoma.

Background: Abnormal Uterine Bleeding is defined as any deviation from a normal menstrual pattern. It is one of the common presentation in extremes of ages. However endometrial hyperplasia and carcinoma are commoner in perimenopausal and postmenopausal women warranting investigations like ultrasonography and endometrial biopsy.Aims and Objective: The aim of the study was to note the endometrial thickness by transabdominal ultrasonography and observe the histopathological pattern in women presenting with abnormal Uterine Bleeding.Material and Methods: Premenopausal women more than 45 years of age and the postmenopausal patients, without any pelvic pathology were included in the study. Endometrial thickness was measured by transabdominal sonography and endometrial biopsy was done. Tissue obtained was sent for histopathological examination.Results: A total of 105 patients were studied. Majority (92%) of patients were premenopausal. Proliferative Endometrium (32%) was the most common finding in premenopausal and atrophic endometrium (37.5%) in postmenopausal group. Malignancy was higher in a postmenopausal group (12.5%) as compared to the premenopausal group (2%). Malignancy was not seen when endometrial thickness was less than 11mm in the premenopausal age group. Endometrial hyperplasia was also more common when the thickness was more than 11mm.In postmenopausal group12.5% of patients, had complex hyperplasia.25% had simple hyperplasia and malignancy was seen in 12.5% of patients. When endometrial thickness was less than 5 mm, hyperplasia and malignancy was not seen.Conclusion: Measurement of Endometrial thickness and histopathological workup in patients above 45 years presenting with abnormal uterine bleeding will be helpful in detecting endometrial hyperplasia and carcinoma.Asian Journal of Medical Sciences Vol.9(2) 2018 31-35
