Intergroup-statement: statement of the german ovarian cancer commission, the North-Eastern German Society of gynecological Oncology (NOGGO), AGO Austria and AGO Swiss regarding the use of homologous repair deficiency (HRD) assays in advanced ovarian cancer.

Introduction: Homologous recombination deficiency (HRD) is a key biomarker in the management of high-grade serous ovarian cancer (HGSOC), guiding treatment decisions, particularly regarding the use of poly(ADP-ribose) polymerase inhibitors (PARPi). As multiple HRD assays are available, each with distinct methodologies and cutoff values, the interpretation and clinical application of HRD testing remain complex. This intergroup statement, endorsed by the German Ovarian Cancer Commission, NOGGO, AGO Austria, and AGO Swiss, aims to provide guidance on the indications, appropriate use, and limitations of HRD testing in ovarian cancer.

We evaluate lymphadenectomy (LNE) rates in dependence on histologic subtype and outcome for early ovarian cancer FIGO I.

Methods: Therapy quality was defined according to national guidelines.

Genetic Variants of Interleukin-8 and Interleukin-16 and Their Association with Cervical Cancer Risk.

Background: Cervical cancer (CC) is the fourth most common cancer diagnosis in women worldwide. Infection with high-risk human papillomavirus (HPV) is a critical but not determinative condition for CC development, as several co-factors modulate the progression of HPV-associated cervical lesions. Interleukin-8 (IL-8) and Interleukin-16 (IL-16) are chemokine-like interleukins involved in the pathogenesis of various cancers.

Risk factors for anastomotic leakage and its impact on survival outcomes in radical multivisceral surgery for advanced ovarian cancer: an AGO-OVAR.OP3/LION exploratory analysis.

Background: Anastomotic leakage is a significant complication following bowel resection in cytoreductive surgery for ovarian cancer. Previous studies have highlighted the detrimental effects of anastomotic leakage on patients' postoperative course. However, there is still a lack of precise identification of the high-risk population and established strategies for preventing its occurrence.

Influence of breast cancer on life satisfaction in the elderly patient.

Purpose: Due to increasing life expectancy and demographic trends in recent years, the specific needs of elderly patients have gained more and more attendance. The aim of this study is to determine the impact of adjuvant chemotherapy on health-related life satisfaction of elderly breast cancer patients while considering the conditions of comorbidities and global health status.

Methods: All breast cancer patients over 60 years who had been treated at the Breast Center of the University Hospital of Munich, Germany between 2010 and 2013 were eligible for participation.

Minimally invasive compared to open surgery in patients with low-risk cervical cancer following simple hysterectomy: An exploratory analysis from the Gynegologic Cancer Intergroup/Canadian Cancer Trials Group CX.5/SHAPE trial.

Objective: The Laparoscopic Approach to Cervical Cancer trial demonstrated that minimally invasive radical hysterectomy was associated with worse disease-free survival and overall survival among women with early-stage cervical cancer. It is unknown whether this applies to patients with low-risk disease following simple hysterectomy.

Methods: Among patients who underwent simple hysterectomy in the Simple Hysterectomy And PElvic node assessment trial, univariate and multivariate Cox models were used to assess the association of minimally invasive versus open surgery with clinical outcomes, including pelvic and extra-pelvic recurrence-free survival, overall recurrence-free survival, and overall survival.

Necroptosis-Related Gene Signature Predicts Prognosis in Patients with Advanced Ovarian Cancer.

This study aimed to construct a risk score (RS) based on necroptosis-associated genes to predict the prognosis of patients with advanced epithelial ovarian cancer (EOC). EOC data from The Cancer Genome Atlas (TCGA) and the Gene Expression Omnibus (GEO) series 140082 (GSE140082) were used. Based on known necroptosis-associated genes, clustering was performed to identify molecular subtypes of EOC.

Evaluation of therapy support through a standardized nursing consultation for patients undergoing oral tumor therapy in gynecological oncology within the prospective CAMPA initiative.

Purpose: The increase of oral tumor therapies (OTT) poses new challenges in patient care. Within CAMPA (Care improvement for advanced or metastatic breast and ovarian cancer patients treated with PARP-inhibitors), additional nursing support for patients treated with PARP-inhibitors was developed.

Methods: Additional nursing support (1 year) was evaluated in breast and gynecooncological cancer patients at an academic and a non-academic outreach center.

Establishment of Stable Knockdown of MACC1 Oncogene in Patient-Derived Ovarian Cancer Organoids.

High-grade serous ovarian cancer (HGSOC) remains the most lethal gynecological malignancy, and there is still an unmet medical need to deepen basic research on its origins and mechanisms of progression. Patient-derived organoids of high-grade serous ovarian cancer (HGSOC-PDO) are a powerful model to study the complexity of ovarian cancer as they maintain, in vitro, the mutational profile and cellular architecture of the cancer tissue. Genetic modifications by lentiviral transduction allow novel insights into signaling pathways and the potential identification of biomarkers regarding the evolution of drug resistance.

Efficacy of the "7mind"-app as intervention to prevent postpartum depression in a low-risk sample group.

Introduction: Postpartum depression (PPD) is a severe complication in the postpartum period and equals a major depression occurring in the first weeks after delivery. During the COVID-19 pandemic, an increased incidence of PPD was observed. For this reason, we conducted an intervention study to test the effectiveness of the "7mind"-app, an app-based mindfulness training program, in the prevention of PPD.

Association of the Single Nucleotide Polymorphisms rs11556218, rs4778889, rs4072111, and rs1131445 of the Interleukin-16 Gene with Ovarian Cancer.

Single nucleotide polymorphisms (SNPs) of the IL-16 gene have been reported to influence the risk of several cancers, but their role in ovarian cancer (OC) has not been studied. Using the restriction fragment length polymorphism (PCR-RFLP) method, we examined four IL-16 SNPs: rs11556218 (T > G), rs4778889 (T > C), rs4072111 (C > T), and rs1131445 (T > C) in blood samples from 413 women of Central European descent, including 200 OC patients and 213 healthy controls. Among the patients, 62% were postmenopausal, 84.

The expression of galectins is increased in several tumor types and that they are involved in important cell processes.

Loss of copy numbers of retrotransposons (HERVK) on chromosome 7p11.2 impacts EGFR (Epidermal Growth Factor Receptor)-induced phenotypes for platinum sensitivity and long-term survival in ovarian cancer-A study from the OVCAD consortium.

We analyzed variations in the epidermal growth factor receptor (EGFR) gene and 5'-upstream region to identify potential molecular predictors of treatment response in primary epithelial ovarian cancer. Tumor tissues collected during debulking surgery from the prospective multicenter OVCAD study were investigated. Copy number variations in the human endogenous retrovirus sequence human endogenous retrovirus K9 (HERVK9) and EGFR Exons 7 and 9, as well as repeat length and loss of heterozygosity of polymorphic CA-SSR I and relative EGFR mRNA expression were determined quantitatively.

Placental expression of inflammatory Galectin-12 is associated with gestational diabetes.

Objectives: Gestational diabetes mellitus (GDM) is a growing health concern. Since members of the galectin-family are identified to play a role in the pathogenesis of GDM, we determined galectin-12 as an essential protein due to its influence in lipolysis and inflammation processes. This study investigates the expression of galectin-12 in the placentas of women with GDM.

Strategy for Biobanking of Ovarian Cancer Organoids: Addressing the Interpatient Heterogeneity across Histological Subtypes and Disease Stages.

While the establishment of an ovarian cancer biobank from patient-derived organoids along with their clinical background information promises advances in research and patient care, standardization remains a challenge due to the heterogeneity of this lethal malignancy, combined with the inherent complexity of organoid technology. This adaptable protocol provides a systematic framework to realize the full potential of ovarian cancer organoids considering a patient-specific variability of progenitors. By implementing a structured experimental workflow to select optimal culture conditions and seeding methods, with parallel testing of direct 3D seeding versus a 2D/3D route, we obtain, in most cases, robust long-term expanding lines suitable for a broad range of downstream applications.
