Objective: The incidence of carcinoma of endometrium in younger patients has increased tendency. Experimental data support that mutation of tumor suppressor gene TP53 plays an important role in endometrial carcinogenesis
Material And Methods: Exons 2-11 of the gene TP53 into tissues of endometrial carcinoma and precancerous lesions were analyzed by DNA sequencing and restriction analysis.
Results: A polymorphism CCC/CGC at codon 72 was identified in exon 4 of TP53 gene of all precancerous lesions and carcinomas of endometrium.
Conclusion: Our results also suggest presence of endometrial glandular dysplasia or serous histological type of endometrial carcinoma into examined samples. Given the course and prognosis of serous endometrial carcinoma, it is necessary and useful to identify this type of cancer in the mixed types of endometrial carcinomas. DNA analysis has potential to make diagnostic process more specific and affect to adjuvant therapy and survival of patients.

The combination therapy of lenvatinib plus pembrolizumab (LP) is increasingly recognized as an important second-line regimen for advanced or recurrent endometrial cancer (EC). However, the safety and efficacy of conversion surgery with low anterior rectal resection for unresectable EC following LP therapy is unknown. A 37-year-old woman was referred with unresectable EC with pleural fluid, peritoneal dissemination, and ascites.

Aim: To compare the prognosis of low-grade endometrial carcinoma (LG-EC) with that of high-grade endometrial carcinoma (HG-EC) after first recurrence/relapse before the molecular targeted therapy era.
Methods: Recurrent/relapsed endometrial cancer was diagnosed in 155 women at our hospital between January 26, 1999 and February 26, 2019. Fifty of these women received paclitaxel-carboplatin, two received doxorubicin-cisplatin, and one received docetaxel-carboplatin as postoperative chemotherapy.

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.

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.
