We have previously reported that both endometrial cancer and endometrial hyperplasia stain positively for the anti-LeY monoclonal antibody, whereas normal endometrium does not. Endometrial hyperplasia is a premalignant change associated with the eventual development of endometrial carcinoma. However, it can be difficult to differentiate hyperplasia from normal endometrium in cytology. This study illustrates the use of immunocytochemical cytology using anti-LeY monoclonal antibody to differentiate between endometrial hyperplasia and normal endometrium. Immunostaining using anti-LeY monoclonal antibody was performed on cytologic specimens obtained from 17 normal endometria, 25 endometria with endometrial hyperplasia, and 13 endometria with endometrial carcinoma. All normal endometria displayed negative staining for anti-LeY monoclonal antibody, whereas all endometria with endometrial carcinoma displayed positive staining. Of the endometrial hyperplasia cases, 21 displayed positive staining. However, four displayed negative staining due to the small number of cells available for diagnosis. We believe that immunostaining cytology using anti-LeY monoclonal antibody is a useful method for differentiating between normal endometrium and endometrial hyperplasia.

Endometrial carcinoma (EC) is the most common gynecological cancer. However, there is currently no routinely used biomarker for differential diagnosis of malignant and premalignant endometrial lesions. Ten-eleven translocation (TET) proteins, especially TET1, were found to play a significant role in DNA demethylation, via conversion of 5-methylcytosine (5-mC) to 5-hydroxymethylcytosine (5-hmC). TET1, 5-mC, and 5-hmC expression profiles in endometrial carcinogenesis are currently unclear. We conducted a hospital-based retrospective review of the immunohistochemical expression of TET1, 5-mC, and 5-hmC in 181 endometrial samples. A “high” TET1 and 5-hmC expression score was observed in all cases of normal endometrium (100.0% and 100.0%, respectively) and in most samples of endometrial hyperplasia without atypia (90.9% and 78.8%, respectively) and atypical hyperplasia (90.6% and 93.8%, respectively), but a “high” score was found in only less than half of the EC samples (48.8% and 46.5%, respectively). The TET1 and 5-hmC expression scores were significantly higher in normal endometrium and premalignant endometrial lesions than in ECs (p < 0.001). A “high” 5-mC expression score was observed more frequently for ECs (81.4%) than for normal endometrium (40.0%), endometrial hyperplasia without atypia (51.5%), and atypical hyperplasia (53.1%) (p < 0.001). We also found that TET1 mRNA expression was lower in ECs compared to normal tissues (p = 0.0037). TET1 immunohistochemistry (IHC) scores were highly proportional to the TET1 mRNA levels and we summarize that the TET1 IHC scoring can be used for biomarker determinations. Most importantly, a higher TET1 score in EC cases was associated with a good overall survival (OS) rate, with a hazard ratio (HR) of 0.31 for death (95% confidence interval: 0.11–0.84). Our findings suggest that TET1, 5-mC, and 5-hmC expression is a potential histopathology biomarker for the differential diagnosis of malignant and premalignant endometrial lesions. TET1 is also a potential prognostic marker for EC.

Abstract Background Endometrial carcinoma is the most common gynecological malignancy in the developed countries and the third common gynecological malignancy in Egypt after breast and ovarian cancers. Aim of the Work to evaluate this risk scoring model on Egyptian patients and to study the effect of adding other patient characteristics (DM, BMI and relevant family history) on the sensitivity and specificity of RHEA scoring model. Patients and Methods The current study was conducted in Ain Shams University Maternity Hospital in the period between September 2017 and December 2018. A total of 100 women with postmenopausal bleeding and endometrial thickness &gt; 4mm were included in the study. Results Histological examination revealed that benign pathology (n = 65) (73%) was found to be: most common cause was endometrial hyperplasia without atypia (20.3%) followed by chronic endometritis (13.5%), then endometrial polyp (11.3%), cystic atrophy of endometrium (8.9%), proliferative endometrium (8.9%), endometrial hyperplasia with atypia (6.7%) and lastly mucous polyp (3.4%) while malignant histopathology(n = 24)(27%) which is significantly higher than the international rates showed: Endometriod adenocarcinoma (n = 19)(21.3%), papillary serous carcinoma (n = 4)(4.5%) and undifferentiated carcinoma (n = 1)(1.1%). The current study showed that RHEA score performs in our study population with a comparable validity to that reported by its inventors with sensitivity 79.2% (57.8% - 92.9%) vs. 87.5% and specificity 84.6% (73.5% - 92.4%) vs. 80.1% respectively. In results of the current study it was found that the time since onset of menopause rather than age was associated with endometrial cancer with the optimum cut-off for postmenopausal duration was estimated to be 9 years achieving a sensitivity of 87.5% and a specificity of 60.0%, but it needs multivariate analysis on larger and more representative sample size to confirm this association, A statistically significant regression model was including only postmenopausal duration, recurrent bleeding and endometrial thickness. None of age, BMI, family history or hypertension proved a statistically significant predictive effect after adjustment for other predictive variables. Conclusion Taking in consideration the higher prevalence of endometrial carcinoma in the sample of the current study, the wide 95% confidence intervals for the different validity indices for the RHEA scores derived from this study, it seems that RHEA score performs in this study population with a comparable validity to that reported by its inventors.

OBJECTIVE: This study was conducted to evaluate the relationship of p53 and Ki67 expression with prognostic factors in patients who underwent surgery due to a diagnosis of endometrial cancer, and to evaluate their use as molecular markers that can help with survival prediction. STUDY DESIGN: This retrospective cohort study included patients who underwent surgery for endometrial cancer indication at the Gynecologic Oncology Clinic of the University of Health Sciences Tepecik Training and Research Hospital between 2011 and 2019, and whose p53 and Ki67 from the dissected material were pathologically studied and who underwent pelvic/paraaortic lymph dissection between the relevant dates. RESULTS: The study included 140 patients who met the inclusion criteria, 60% (n=84) of whom had endometrioid type endometrial carcinoma and 40% (n=56) had non-endometrioid type endometrial carcinoma. Estrogen and progesterone receptor positivity was significantly higher in the endometrioid type endometrial carcinoma group (p<0.001 and p<0.001, respectively). The non-endometrioid type endometrial carcinoma group had a high degree of positive staining (+3 and +4 staining) with p53 was 51.8%, while this rate was 11.9% in the endometrioid type endometrial carcinoma group. The non- endometrioid group also had a high degree of positive staining of Ki67 at 51.8%, whereas the endometrioid group had 25%. The total staining rate with p53 and Ki67 was significantly higher in the non-endometrioid type group (p<0.001 and p=0.001, respectively). The mean survival duration was less than six months in cases with high degree positive p53 [57.4±2.7, (52.1-62.8) vs 51.9±5.9, (41.8-61.9)] and the mean survival duration was less than eight months in cases with high degree positive Ki67 [59.6±2.9, (53.8-65.4) vs 51.6±4.3, (43.2-60.1)]. CONCLUSION: p53 and Ki67 can be new markers for the prediction of prognosis and duration in endometrial cancer. The results of this study pave the way for new studies: however, randomized controlled prospective and multi-center studies are needed for immunohistochemical measures to be used as a parameter.
