Aim: To quantify the apoptotic phenomenon on endometrial biopsies in postmenopausal patients under hormonal replacement therapy (HRT).
Material And Methods: The study lot consisted of 30 endometrial biopsies on which we studied the apoptotic phenomenon through morphological and molecular biology techniques (TUNEL reaction). Examination of endometrial biopsies before and post-therapeutically has been made.
Results And Discussions: From morphological point of view, pre-therapeutically, endometrial biopsies presented apoptotic changes in about 1-3% of cells and under TSH there have been observed apoptotic changes in about 1-2% of cells. In female reproductive system, we found out a raised rate of cellular proliferation and concurrently a raised rate of apoptosis. Apoptotic phenomenon can be observed in endometrium at every menstrual cycle. In proliferative endometrium apoptosis rate is low, but in endometrial carcinoma apoptosis rate grow up. Bcl2 and Bax are expressing in normal and hyperplastic endometrium, but in endometrial carcinoma Bcl2/Bax ratio decline.
Conclusions: Quantification of apoptosis, using morphological and TUNEL reaction methods, on endometrial biopsies in postmenopausal patients before and after therapy indicate a low rate of apoptotic phenomenon.

Int J Gynecol Cancer
January 2025
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.

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.

Objective: The aim of this study was to examine the role of pre-sacral sentinel lymph nodes (SLNs) in patients with uterine cancer.
Methods: This retrospective cohort study includes patients with endometrial or cervical cancer who underwent minimally invasive indocyanine green SLN mapping at the Bern University Hospital from December 2012 to December 2022. A complete ultra-staging of the SLNs was performed in all cases.

Objective: No biomarkers are available to predict treatment response in patients with endometrial cancers who undergo fertility-sparing treatment. Therefore, we aimed to evaluate the prognostic role of molecular classification.
Methods: Patients with endometrial cancer who underwent fertility-sparing treatment with progestins between 2005 and 2021 were retrospectively identified.

Objective: Evaluation of prognostic factors is crucial in patients with endometrial cancer for optimal treatment planning and prognosis assessment. This study proposes a deep learning pipeline for tumor and uterus segmentation from magnetic resonance imaging (MRI) images to predict deep myometrial invasion and cervical stroma invasion and thus assist clinicians in pre-operative workups.
Methods: Two experts consensually reviewed the MRIs and assessed myometrial invasion and cervical stromal invasion as per the International Federation of Gynecology and Obstetrics staging classification, to compare the diagnostic performance of the model with the radiologic consensus.
