Circular RNAs (circRNAs) are a naturally occurring family of non-coding RNA that may regulate gene expression in mammals. circRNAs are more stable than messenger RNAs due to their resistance to RNA exonuclease. A growing body of evidence has shown that the expression of circRNAs is regulated during development in a tissue-specific manner. CircRNAs have been implicated in a number of cancers; however, their role in endometrial cancer (EC) is completely unknown. Here, we report the circular transcriptome specific for EC as determined by RNA sequencing. We found that the overall abundance of circRNAs is lower in EC than in normal endometrium. Further, there are numerous 'hotspot' genes from which circRNAs are transcribed that may account for alterations in circRNA expression between the normal and malignant endometrium. Most importantly, we have also identified circRNAs that are differentially expressed between malignant and normal endometrial tissue. The functional significance of these circRNAs in cancer remains to be determined, but they may serve as potential biomarkers for the diagnosis of EC or monitoring of EC progression.

Only a few human ovarian endometrioid carcinoma cell lines are currently available, partly due to the difficulty of establishing cell lines from low-grade cancers. Here, using a cell immortalization strategy consisting of i) inactivation of the p16-pRb pathway by constitutive expression of mutant cyclin-dependent kinase 4 (R24C) (CDK4) and cyclin D1, and ii) acquisition of telomerase reverse transcriptase (TERT) activity, we established a human ovarian endometrioid carcinoma cell line from a 46-year-old Japanese woman. That line, designated JFE-21, has proliferated continuously for over 6 months with a doubling time of ~ 55 h.

Objectives: Due to the increasingly faster pace of life and responsibilities, stress has become an integral part of daily life. Every year, numerous social campaigns in the media raise the issue of increasing alcohol consumption. Endometriosis is a chronic, causally incurable, estrogen-dependent and inflammatory gynecological disorder, described as presence of ectopic endometrial tissue outside the uterine cavity.

Brigham and Women's Hospital, Department of Obstetrics, Gynecology, and Reproductive Biology, Boston, MA, USA.
Objective: The goal of this study was to evaluate safety after same-day discharge following minimally invasive hysterectomy for endometrial cancer and endometrial intraepithelial neoplasia in patients with and without morbid obesity (body mass index 40 kg/m). Our secondary objective was to identify barriers to same-day discharge.
Methods: Retrospective cohort study of patients undergoing minimally invasive hysterectomy for endometrial cancer and endometrial intraepithelial neoplasia from January 2016 to May 2022.
Risk factors for the involvement of sentinel lymph nodes in endometrial cancer (TRSGO-SLN-010).

Division of Gynecologic Oncology, Koc University School of Medicine, Istanbul, Turkey.
Objective: This research was undertaken to identify risk factors for the involvement of sentinel lymph nodes (SLNs) in cases of endometrial cancer.
Methods: From February 2016 to April 2021, the cases of 874 women with endometrial cancer treated with the SLN algorithm at 11 institutions were analyzed in this retrospective study. Clinical and pathologic data were reviewed, and logistic regression was applied to identify predictive factors for SLN involvement.
