Prostaglandin E (PGE) has contradictory effects in many organs. It may have proinflammatory, anti-inflammatory, or anti-fibrotic roles, depending on the type of receptors to which it binds. By signaling through its receptors EP2 and EP4, PGE mediates anti-inflammatory and anti-fibrotic actions. Read More

Background: In patients with endometrial cancer sentinel lymphadenectomy is used to accurately prognosticate extent of disease and has been proposed as a method to decrease the incidence of medical and surgical complications associated with more extensive lymphadenectomy. It is unknown if patients who undergo traditional lymphadenectomy experience major postoperative complications at the same rates as those who undergo sentinel lymphadenectomy or those who do not undergo lymphadenectomy.
Objective: To compare the incidence of major postoperative complications among endometrial cancer patients undergoing total laparoscopic hysterectomy with traditional lymphadenectomy versus sentinel or no lymphadenectomy. Read More

Background: Endometrial carcinoma is the most common gynaecologic malignancy in the world and develops through preliminary stages of endometrial hyperplasia. Atypical endometrial hyperplasia suggests a significant pre-malignant state with frank progression to endometrial carcinoma, and tends to occur at a young age. Oral progestins have been used as conservative treatment in young women with atypical endometrial hyperplasia, but they are associated with poor tolerability and side effects that may limit their overall efficacy.

The focus of my life in science, has been to improve reproductive health for women, with an emphasis on the endometrium, the most dynamic tissue in the human body: its remarkable cyclical remodelling is essential for establishment of pregnancy. The most notable events in a woman's endometrial cycle are menstruation and endometrial repair, regeneration of the endometrium during the proliferative phase, attainment of receptivity by the mid-secretory phase of the cycle and the embryo-maternal interactions that initiate peri-implantation events within the microenvironment of the uterine cavity. I have contributed to understanding the molecular and cellular changes underpinning these events, and how disturbance of them leads to menstrual disorders, infertility and endometrial diseases including abnormal uterine bleeding, endometriosis and endometrial cancer.

Introduction: Endometriosis consists in the proliferation of endometrial tissue outside of the uterine cavity, predominantly in the ovaries but also in the urinary bladder or bowel. About 10% of fertile women are affected and the main symptoms are pain, menstrual disorders and infertility. Surgery is the treatment option for those symptomatic patients in which medical treatment had no success. Read More

Purpose Of Review: The present article reviews genomic subtyping of endometrial carcinoma and new molecular markers with therapeutic and prognostic implications.
Recent Findings: Endometrial cancer has historically been classified through histology into endometrioid (type 1) and nonendometrioid (type II, mainly serous) subtypes. Molecular classification through genomic analysis now allows for a major advance in characterization; four distinct subgroups have been identified: polymerase ε (POLE) ultramutated, microsatellite unstable, copy number low/microsatellite stable, and copy number high/'serous-like'.

Uterine endometrial carcinoma is one of the common cancers in females. Cancer stem-like cells (CSCs)/cancer-initiating cells (CICs) are a small subpopulation of cancer cells that are tumorigenic and are resistant to treatments, thus they are focused as treatment targets. However, the heterogeneity of CSCs/CICs is still elusive, and we therefore analyzed CSCs/CICs at the clonal level. Read More

Study Question: In IVF cycles in which the entire embryo cohort is slow growing, is it optimal to perform fresh transfer in Day 5 or to extend the culture and transfer in subsequent vitrified-warmed cycles?
Summary Answer: The outcomes depend on the degree of embryo development on Day 5.
What Is Known Already: Slow-growing blastocysts have lower implantation potential when transferred in fresh cycles. It has been suggested that embryo-endometrial asynchrony could explain this finding. Read More

Abnormal uterine bleeding in women aged 35 years or over is an important clinical sign of many gynecological conditions. The diagnoses of these conditions require the pathological report of the endometrial tissue. Outpatient-based endometrial biopsy is an excellent option compared to standard fractional uterine curettage or hysteroscopy with endometrial biopsy in providing a definite diagnosis for abnormal uterine bleeding as it is less painful and does not require high potency anesthesia.
