Objective: To evaluate the value of three-dimensional transvaginal sonography and hysterosonography in the diagnosis of endometrial lesion in women with postmenopausal bleeding.
Methods: A total of 74 patients with postmenopausal bleeding were prospectively studied by two- and three-dimensional transvaginal sonography. Endometrial thickness and volume were measured by 2D and 3D ultrasound respectively. Endometrial thickness was found by hysterosonography at greater than 5 mm in 32 cases. Changes of endometrium and compliance of muscularis uteri were observed. The results were correlated with histopathological findings.
Results: When 10 ml of endometrial volume was set as the cut-off point of endometrial abnormalities in postmenopausal women with bleeding, the sensitivity and false positive rate were 95.4%, 21.2% whereas 100%, 18.2% were obtained respectively when it was used to predict endometrial malignancy and premalignancy. The accurate rate of 2D-HSG diagnosing endometrial disorders and endometrial malignancy and pre-malignancy was 96. 8% and 100% respectively. Changes of endometrium and compliance of muscularis uteri showed a significant difference between the groups of benign and malignancy after the injection of fluid into uterine cavity (P < 0.05).
Conclusion: 3D-TVS and 2D-HSG are reliable methods in screening endometrial lesions. 2D-HSG should be regarded as an important tool in diagnosing and differentiating endometrial lesions especially in early stages of this malignant disease. Changes of endometrium and compliance of muscularis uteri may help to differentiate benign disorders from endometrial cancer.

Objectives: We focused on how the immunophenotypes based on the distribution of CD8-positive tumor-infiltrating lymphocytes (TILs) relate to the endometrial cancer (EC) molecular subtypes and patients' prognosis.
Patients And Methods: Two cohorts of EC patients (total n = 145) were analyzed and categorized using the Molecular Risk Classifier for Endometrial cancer (ProMisE): POLEmut (POLE mutation), MMRd (mismatch repair deficiency), NSMP (no specific molecular profile), and p53abn (p53 abnormality). CD8-positive TILs, within the central tumor and the invasive margin, were examined by using immunohistochemical staining and advanced image-analysis software.

Objective The purpose of this study was to investigate how miR-200b-3p inhibitors the proliferation and metastasis of endometrial cancer(EC) cells by inducing the expression of FOS-like antigen 2(FOSL2) of activator protein 1(AP1) transcription family. Methods Endometrial cancer cell line HEC-1-A was divided into 12 groups: NC-mimic (transfected with negative control NC mimic), miR-200b-3p mimic (transfected with miR-200b-3p mimic), NC-inhibitor (transfected with negative control NC inhibitor), miR-200b-3p inhibitor group (transfected with miR-200b-3p inhibitor), si-NC (transfected with negative control Si-NC), si-FOSL2 (transfected with si-FOSL2), oe-NC (transfected with negative control oe-NC), oe-FOSL2 group (oe-FOSL2), miR-200b-3p mimic+oe-NC group (co-transfected with miR-200b-3p mimic and oe-NC), miR-200b-3p mimic+oe-FOSL2 group (co-transfected with miR-200b-3p mimic and oe-FOSL2), miR-200b-3p inhibitor+si-NC group (co-transfected with miR-200b-3p inhibitor and si-NC), miR-200b-3p inhibitor+si-FOSL2 group (co-transfected with miR-200b-3p inhibitor and si-FOSL2). Real-time fluorescence quantitative PCR, Western blot, CCK-8 assay, scratch test and Transwell assay were used to detect the expression of miR-200b-3p mRNA, FOSL2 mRNA and protein expression level, cell proliferation, migration and invasion.

The protective effect of parity has been demonstrated for cancer of the breast, ovary, and endometrium but no studies have estimated the effect of each subsequent birth in women with 10 or more children or grand-grand parity women, nor compared the linear relationship of the three cancers sites. Here, we aim to explore these relationships based on the Norwegian 1960 Census. The question of parity in present marriage was answered by 385,816 women born 1870-1915, a period with high fertility.

Objective: This study provides a comprehensive analysis of endometrial cancer incidence trends in Hong Kong over the past three decades. It aims to evaluate the impact of demographic shifts and epidemiological factors, including age, birth cohort, and diagnosis period, on the incidence rates. The study also projects future trends in endometrial cancer cases up to 2030 and assesses the contributions of these factors using a detailed decomposition approach.

P53-abnormal endometrial carcinomas are high-grade and aggressive tumors which should be treated with chemo-/radiotherapy. In low-grade endometrioid carcinoma (LGEC), abnormal expression of p53 is an exceptional finding and is typically accompanied by patchy p16 positivity and diffuse hormone receptor expression. Herein, we report a case of LGEC exhibiting both p53 and p16 overexpression, highlighting the diagnostic pitfalls related to such phenotype.
