Determination of nuclear and/or cytoplasmic expression of β-catenin by immunohistochemistry in patients with endometrial cancer (EC) may constitute a potential diagnostic method for identifying patients with a catenin β1 (CTNNB1) gene mutation and those at risk of disease recurrence. The present study aimed to investigate β-catenin expression patterns in hysterectomy specimens of patients with endometrioid type EC using immunohistochemistry, and to examine the prognostic impact of β-catenin. The study was a single-institutional, retrospective cohort trial enrolling consecutive patients with a postoperative histopathological diagnosis of endometrioid EC who underwent hysterectomy between January 2015 and December 2018.

Objective: We aimed to investigate differences between HPV-16 mono- and HPV-16/18 co-infections in terms of cervical dysplasia and invasive cancer.

Methods: This multicentre, retrospective study spanned from December 2017 to December 2020, involving women who visited gynaecological oncology clinics for colposcopy with either HPV-16 or HPV-16/18 positivity. A total of 736 patients, 670 in Group 1 (HPV-16 positivity) and 66 in Group 2 (HPV-16/18 positivity), were compared for the presence of CIN2+ lesions detected by colposcopic biopsy or endocervical curettage (ECC).

Objective: To determine whether patients with atypical squamous cells, cannot exclude high grade squamous intraepithelial neoplasia (ASC-H) cytology have a correlation between high-risk human papillomavirus (HPV) type and CIN 2+ lesion in final pathology.

Material And Methods: The study was conducted retrospectively, using data from three tertiary gynecologic oncology centers located in various regions of Turkey. Data from 5,271 patients who had colposcopy between January 2003 and January 2021 were analyzed.

Despite the theoretical benefits, the favorable effect of preoperative carbohydrate loading on postoperative morbidity remains controversial. Most of the outcomes reported in the literature are derived from non-gynecologic surgery data, with only one study involving a limited number of patients specifically in gynecological oncology. The present study aimed to investigate the impact of carbohydrate loading, as a single element of enhanced recovery after surgery protocols, on postoperative course and morbidity in patients undergoing debulking surgery for epithelial ovarian cancer (EOC).

Objective: The main feature of adult granulosa cell tumors (AGCT) is their capacity to secrete hormones, with nearly all of them capable of synthesizing oestradiol. The primary goal of this study is to identify synchronized endometrial pathologies, particularly endometrial cancer, in AGCT patients who had undergone a hysterectomy.

Materials And Methods: The study cohort comprised retrospectively of 316 AGCT patients from 10 tertiary gynecological oncology centers.

Objective: To define the clinical, histopathological features and the prognostic factors affecting survival in patients with adult granulosa cell tumors of the ovary (AGCT).

Methods: A 322 patients whose final pathologic outcome was AGCT treated at nine tertiary oncology centers between 1988 and 2021 participated in the study.

Results: The mean age of the patients was 51.
