OBJECTIVE: To critically evaluate the evidence linking endometriosis to ovarian cancer, with particular focus on endometrioid and clear cell histologic subtypes, and to inform risk stratification and patient counseling. METHODS: A systemat…

Cancer diagnoses in patients of reproductive age require balancing urgent oncological treatment with the need to preserve fertility. This FIGO Best Practice Advice outlines key considerations for fertility management in this population give…

Patients with high-grade endometrial carcinoma (EC) have an increased risk of tumor spread and lymph node metastasis (LNM). Preoperative imaging and CA125 can be used in work-up. As data on cancer antigen 125 (CA125) in high-grade EC are li…

The distinguishing of uterine leiomyosarcomas (ULMS) and uterine leiomyomas (ULM) before the operation and histopathological evaluation of tissue is one of the current challenges for clinicians and researchers. Recently, a few new and innov…

Transient receptor potential (TRP) channels excel in cellular sensing as they allow rapid ion influx across the plasma membrane in response to a variety of extracellular cues. Recently, a distinct TRP mRNA expression signature was observed …

STUDY QUESTION: What is the recommended management for women and transgender men with regards to fertility preservation (FP), based on the best available evidence in the literature? SUMMARY ANSWER: The ESHRE Guideline on Female Fertility P…

Several studies support, both in vitro and in vivo, the anti-cancer effects of cannabidiol (CBD), a transient receptor potential vanilloid 2 (TRPV2) ligand. TRPV2, often dysregulated in tumors, is associated with altered cell proliferation …

Epidemiological, biological, and molecular data suggest links between endometriosis and endometrial cancer, with recent epidemiological studies providing evidence for an association between a previous diagnosis of endometriosis and risk of …

Endometrial cancer is the most common type of cancer of the female reproductive tract. Although prognosis is generally good for patients with low-grade and early-stage diseases, the outcomes for high-grade and metastatic/recurrent cases rem…

The endometrium, which is of crucial importance for reproduction, undergoes dynamic cyclic tissue remodeling. Knowledge of its molecular and cellular regulation is poor, primarily owing to a lack of study models. Here, we have established a…

OBJECTIVE: Epithelial ovarian cancers (EOCs) are, although still treated as a single disease entity, often classified into type I tumors (low-grade serous, mucinous, endometrioid, clear cell) and type II tumors (high-grade serous, undiffere…

14-3-3 proteins are ubiquitously expressed regulators of various cellular functions, including proliferation, metabolism, and differentiation, and altered 14-3-3 expression is associated with development and progression of cancer. We report…

BACKGROUND: Recent insights provide support for the treatment of cancer during pregnancy, a coincidence that poses both mother and fetus at risk. Our aim was to critically review studies on the physiologic variations during pregnancy, the m…

BACKGROUND: The development of cancer from adenomyotic foci is a rare occurrence. The diagnosis is frequently delayed because of the absence of tumor in the eutopic endometrium. CASE REPORT: We present a case of a 64-year-old postmenopausa…

We report a case of polypoid bladder endometriosis in pregnancy. Diagnostic workup showed a vesicouterine well-vascularized polypoid mass, suspicious for malignancy. During pregnancy, the mass was surgically resected with safe oncological m…

Pelvic surgery for gynecological cancer can affect sexuality through a number of anatomical, physiological and psychological mechanisms. We aimed to examine the prevalence of sexual dysfunction and psychological functioning in women who und…

Innervation of deep endometriosis has recently been linked to its severe pain symptoms. We demonstrated for the first time that the Wilms' tumor gene 1 is overexpressed in part of these nerves.
