INTRODUCTION
Many advances in the understanding of the pathologic and molecular features of endometrial cancer have occurred since the FIGO staging was last updated in 2009. Substantially more outcome and biological behavior data are now available regarding the several histological types. Molecular and genetic findings have accelerated since the publication of The Cancer Genome Atlas (TCGA) data and provide improved clarity on the diverse biological nature of this collection of endometrial cancers and their differing prognostic outcomes. The goals of the new staging system are to better define these prognostic groups and create substages that indicate more appropriate surgical, radiation, and systemic therapies.
METHODS
The FIGO Women's Cancer Committee appointed a Subcommittee on Endometrial Cancer Staging in October 2021, represented by the authors. Since then, the committee members have met frequently and reviewed new and established evidence on the treatment, prognosis, and survival of endometrial cancer. Based on these data, opportunities for improvements in the categorization and stratification of these factors were identified in each of the four stages. Data and analyses from the molecular and histological classifications performed and published in the recently developed ESGO/ESTRO/ESP guidelines were used as a template for adding the new subclassifications to the proposed molecular and histological staging system.
RESULTS
Based on the existing evidence, the substages were defined as follows: Stage I (IA1): non-aggressive histological type of endometrial carcinoma limited to a polyp or confined to the endometrium; (IA2) non-aggressive histological types of endometrium involving less than 50% of the myometrium with no or focal lymphovascular space invasion (LVSI) as defined by WHO criteria; (IA3) low-grade endometrioid carcinomas limited to the uterus with simultaneous low-grade endometrioid ovarian involvement; (IB) non-aggressive histological types involving 50% or more of the myometrium with no LVSI or focal LVSI; (IC) aggressive histological types, i.e. serous, high-grade endometrioid, clear cell, carcinosarcomas, undifferentiated, mixed, and other unusual types without any myometrial invasion. Stage II (IIA): non-aggressive histological types that infiltrate the cervical stroma; (IIB) non-aggressive histological types that have substantial LVSI; or (IIC) aggressive histological types with any myometrial invasion. Stage III (IIIA): differentiating between adnexal versus uterine serosa infiltration; (IIIB) infiltration of vagina/parametria and pelvic peritoneal metastasis; and (IIIC) refinements for lymph node metastasis to pelvic and para-aortic lymph nodes, including micrometastasis and macrometastasis. Stage IV (IVA): locally advanced disease infiltrating the bladder or rectal mucosa; (IVB) extrapelvic peritoneal metastasis; and (IVC) distant metastasis. The performance of complete molecular classification (POLEmut, MMRd, NSMP, p53abn) is encouraged in all endometrial cancers. If the molecular subtype is known, this is recorded in the FIGO stage by the addition of "m" for molecular classification, and a subscript indicating the specific molecular subtype. When molecular classification reveals p53abn or POLEmut status in Stages I and II, this results in upstaging or downstaging of the disease (IICm or IAm ).
SUMMARY
The updated 2023 staging of endometrial cancer includes the various histological types, tumor patterns, and molecular classification to better reflect the improved understanding of the complex nature of the several types of endometrial carcinoma and their underlying biologic behavior. The changes incorporated in the 2023 staging system should provide a more evidence-based context for treatment recommendations and for the more refined future collection of outcome and survival data.

Review
Cervical and Vaginal Deciduosis: Insights on Management and a Systematic Review of Observational Studies on Pregnancy Complications and Management Outcomes (Including Vaginal Birth).
INTRODUCTION
Deciduosis is an ectopic transformation of connective tissue into decidual-like cells. This is the first systematic review describing the clinical course, associated pregnancy complications, and management outcomes of cervical and vaginal deciduosis.
METHODS
Our search covered worldwide observational studies published in English in five databases (PubMed, PubMed Central (PMC), Europe PMC, ScienceDirect, and Google Scholar) from inception to February 24, 2023. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines and critically appraised studies using CAse REport (CARE) and Joanna Briggs Institute (JBI) tools. Then, we extracted patient characteristics, clinical features, management-related information, and outcomes.
RESULTS
The selection process identified 15 studies describing 30 pregnancies. Macroscopic cervical and vaginal deciduosis presented as recurrent vaginal bleeding in over 16 of 24 women (57%). Differential diagnoses included miscarriages, cervical pregnancy, placenta previa, and malignancy. Significant antenatal hemorrhages, preterm rupture of membranes, and preterm birth were the most frequent pregnancy complications. Only one of 27 electively performed procedures resulted in biopsy-induced uncontrolled vaginal bleeding (0.04%), suggesting the relative safety of the interventions. Lesion resection led to the cessation of recurrent symptoms in eight of eight patients (100%) compared to eight of 15 women (53%) under observation management. All women with polypoid deciduosis over 1.5 cm entered labor and delivered without complications.
CONCLUSIONS
We described the clinical course, pregnancy complications, diagnostic-related challenges, management, and associated outcomes in women with macroscopic cervical and vaginal deciduosis. We supported the analysis with the current state of the problem and discovered gaps for prospective studies.

Review
Microorganisms are ubiquitous in the human body; they are present in various areas including the gut, mouth, skin, respiratory tract, and reproductive tract. The interaction between the microbiome and reproductive health has become an increasingly compelling area of study. Disruption of the female genital tract microbiome can significantly impact the metabolism of amino acids, carbohydrates, and lipids, increasing susceptibility to reproductive tract diseases such as vaginitis, chronic endometritis, endometrial polyps, endometriosis, and polycystic ovary syndrome. The gut microbiome, considered an endocrine organ, plays a crucial role in the reproductive endocrine system by interacting with hormones like estrogen and androgens. Imbalances in the gut microbiome composition can lead to various diseases and conditions, including polycystic ovary syndrome, endometriosis, and cancer, although research on their mechanisms remains limited. This review highlights the latest advancements in understanding the female genital tract and gut microbiomes in gynecological diseases. It also explores the potential of microbial communities in the treatment of reproductive diseases. Future research should focus on identifying the molecular mechanisms underlying the association between the microbiome and reproductive diseases to develop new and effective strategies for disease prevention, diagnosis, and treatment related to female reproductive organs.

Menopause (New York, N.Y.) Aug 2023Ospemifene is a novel selective estrogen receptor modulator developed for the treatment of moderate to severe postmenopausal vulvovaginal atrophy (VVA). (Meta-Analysis)
Meta-Analysis
Efficacy, tolerability, and endometrial safety of ospemifene compared with current therapies for the treatment of vulvovaginal atrophy: a systematic literature review and network meta-analysis.
IMPORTANCE
Ospemifene is a novel selective estrogen receptor modulator developed for the treatment of moderate to severe postmenopausal vulvovaginal atrophy (VVA).
OBJECTIVE
The aim of the study is to perform a systematic literature review (SLR) and network meta-analysis (NMA) to assess the efficacy and safety of ospemifene compared with other therapies used in the treatment of VVA in North America and Europe.
EVIDENCE REVIEW
Electronic database searches were conducted in November 2021 in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Randomized or nonrandomized controlled trials targeting postmenopausal women with moderate to severe dyspareunia and/or vaginal dryness and involving ospemifene or at least one VVA local treatment were considered. Efficacy data included changes from baseline in superficial and parabasal cells, vaginal pH, and the most bothersome symptom of vaginal dryness or dyspareunia, as required for regulatory approval. Endometrial outcomes were endometrial thickness and histologic classifications, including endometrial polyp, hyperplasia, and cancer. For efficacy and safety outcomes, a Bayesian NMA was performed. Endometrial outcomes were compared in descriptive analyses.
FINDINGS
A total of 44 controlled trials met the eligibility criteria ( N = 12,637 participants). Network meta-analysis results showed that ospemifene was not statistically different from other active therapies in most efficacy and safety results. For all treatments, including ospemifene, the posttreatment endometrial thickness values (up to 52 wk of treatment) were under the recognized clinical threshold value of 4 mm for significant risk of endometrial pathology. Specifically, for women treated with ospemifene, endometrial thickness ranged between 2.1 and 2.3 mm at baseline and 2.5 and 3.2 mm after treatment. No cases of endometrial carcinoma or hyperplasia were observed in ospemifene trials, nor polyps with atypical hyperplasia or cancer after up to 52 weeks of treatment.
CONCLUSIONS AND RELEVANCE
Ospemifene is an efficacious, well-tolerated, and safe therapeutic option for postmenopausal women with moderate to severe symptoms of VVA. Efficacy and safety outcomes with ospemifene are similar to other VVA therapies in North America and Europe.

OBJECTIVES
In this retrospective observational study, cases from our institution were included and the published literature reviewed to investigate the diagnosis and prognosis of cervical rhabdomyosarcoma, a rare group of tumours.
MATERIAL AND METHODS
The clinicopathological data of 12 patients with cervical rhabdomyosarcoma (RMS) treated at the West China Second University Hospital of Sichuan University from January 2006 to May 2023 were collected, and their clinicopathological characteristics, diagnoses, treatments, prognoses and pregnancy outcomes were retrospectively analysed.
RESULTS
(1) Clinical characteristics: The ages of the 12 RMS patients ranged from 15 to 50 years, with a median age of 17 years. Five of the patients were adults, and seven were adolescents. The initial symptoms were vaginal bleeding in 5 patients, vaginal tissue prolapse in 6 patients, and abdominal pain and urinary frequency in 1 patient. Two patients were considered to have "cervical polyps" and underwent polypectomy at the other hospitals, but the cervical mass recurred soon thereafter. (2) Pathological features: The maximum tumour diameter ranged from 3 to 25 cm. The twelve cases of cervical RMS consisted of embryonal rhabdomyosarcoma (ERMS) in 7 adolescents, ERMS in 3 adults, and pleomorphic rhabdomyosarcoma (PRMS) in 2 adults. Immunohistochemical results showed the expression of one or more characteristic markers of RMS. We reclassified tumour stage according to the Intergroup Rhabdomyosarcoma Study (IRS) clinical group and tumour node metastasis (TNM) classification. (3) Treatment: Eight patients underwent radical surgery (66.7%, 8/12), including all 5 of the included adults and 3 of the adolescents, 2 of whom were treated 10 years ago. Conservative surgical resection was performed on four patients (33.3%, 4/12), all of whom were adolescents. Postoperative chemotherapy was given to all patients except one, but one patient who underwent radical surgery discontinued chemotherapy on her own without receiving a full course. Two of the ERMS patients underwent preoperative chemotherapy, and the lesions were significantly reduced. (4) Prognosis: One of the 12 patients with cervical RMS was lost to follow-up. Of the remaining 11 patients, 10 (including seven adolescents and three adults) survived tumour free (90.9%, 10/11), and 1 adult patient with existing pulmonary multiple metastases (IRS stage IV, T2N0M1) at the initial diagnosis survived 9 months with progression-free disease (9.1%, 1/11). The median survival time was 91 months (5 to 213 months). Among 4 patients receiving fertility-sparing management, 1 conceived and delivered successfully (25%).
CONCLUSIONS
The treatment of cervical RMS must take the patient's age and reproductive intent into account. The overall prognosis for cervical RMS in children and adolescents is good, and conservative surgical resection combined with chemotherapy is recommended to preserve fertility. The pregnancy outcome is also worth anticipating. For patients who have completed childbirth, radical surgery is preferred. Approaches to accurately assessing the patient's condition, grasping the indications and scope of surgery, and developing chemoradiotherapy regimens deserve further exploration.

Vaginal fibroepithelial polyps are rare benign tumors of the mucosa of the anterior vaginal wall. In extremely rare cases, they may originate from the posterior vaginal wall or be complicated by torsion. Our case concerns a 63-year-old patient who presented to the gynecology outpatient clinic of the General Hospital of Trikala with minor vaginal bleeding. On vaginal examination, a large pedunculated painless hemorrhagic polypoid mass was noticed, originating from the posterior vaginal wall. A torsion of the pedunculated vaginal tumor was suspected, leading to its surgical excision with clear resection margins. Due to extensive tissue necrosis, accurate histological identification of the vaginal neoplasm was not possible. Histological examination excluded vaginal malignancy. Based predominantly on the clinical and morphological features of the vaginal lesion, a diagnosis of vaginal fibroepithelial polyp with torsion was made, acknowledging its limitations. The patient was discharged from the clinic the same afternoon following the surgery. Three months later, no recurrence of the lesion in the vaginal wall was noted. Following the case presentation, this paper provides a brief literature review of this rare entity, focusing on the diagnostic and therapeutic approaches.

BMC Women's Health Jun 2024Insulin resistance (IR) induces hyperinsulinemia, which activates downstream signaling pathways such as the phosphatidylinositol-3-kinase/protein kinase B (PI3K/AKT)...
BACKGROUND
Insulin resistance (IR) induces hyperinsulinemia, which activates downstream signaling pathways such as the phosphatidylinositol-3-kinase/protein kinase B (PI3K/AKT) pathway, ultimately leading to abnormal proliferation and apoptosis of endometrial cells. This is thought to be a key pathogenic mechanism underlying the development of endometrial polyps (EP). This study aims to investigate the relationship between IR and the development of EP, the expression levels of downstream signaling molecules, including PI3K and AKT, and related laboratory parameters were examined.
METHODS
A total of 100 patients who visited the gynecology outpatient clinic of Zhongda Hospital affiliated with Southeast University from May 2021 to March 2023 and were diagnosed with abnormal endometrial echoes by vaginal ultrasound and underwent hysteroscopic diagnostic curettage were enrolled in this study. General data and relevant hematological indicators were compared, and intraoperative specimens were obtained for pathological examination. Possible factors influencing the development of endometrial polyps were analyzed using Pearson correlation analysis and logistic regression analysis.
RESULTS
In terms of body mass index, waist circumference, fasting insulin, insulin resistance index, serum total testosterone, and free testosterone index, women of childbearing age in the endometrial polyp group had higher values than those in the non-polyp group, while sex hormone-binding globulin in the endometrial polyp group was lower than that in the non-polyp group, and the differences were statistically significant (P < 0.05). The expression scores and mRNA expression levels of PI3K and AKT proteins were higher in the EP group than in the non-EP group (p < 0.05). Pearson correlation analysis showed a positive correlation between HOMA-IR and the expression scores of PI3K and AKT proteins (p < 0.01).
CONCLUSIONS
Insulin resistance and abnormal activation of the phosphatidylinositol 3-kinase/protein kinase B signaling pathway may be potential pathogenic mechanisms for the development of endometrial polyps.

INTRODUCTION
Endometrial polyps (EPs) result from the overgrowth of endometrial glands and stroma. Giant endometrial polyps, defined as those exceeding 4 cm, are rare, and their association with phytoestrogen (PE) intake is infrequently reported.
CASE PRESENTATION
The authors present a case of a giant endometrial polyp in a 59-year-old post-menopausal woman from Nepal. The patient presented with lower abdominal pain and a history of vaginal spotting. She was not under any drugs or medications, including hormones, but had a regular intake of PE-rich foods. Imaging revealed a giant endometrial polyp and a uterine fibroid. Total abdominal hysterectomy and bilateral salpingo-oophorectomy (TAH-BSO) were performed and histopathology examination confirmed the diagnosis of endometrial polyp and fibroid.
DISCUSSION
In our case, the patient's increased age and PE-rich diet were identified as potential risk factors for the giant endometrial polyp. Giant endometrial polyps are rare, with limited cases reported to date, often associated with tamoxifen or raloxifene use. Phytoestrogens can exhibit oestrogenic effects, contributing to endometrial polyps. This case emphasizes the importance of further research to explain the relationship between phytoestrogen intake and giant endometrial polyps.
CONCLUSION
Giant endometrial polyps are uncommon, and their association with phytoestrogen intake remains underexplored. Clinicians should consider dietary factors in history while evaluating endometrial polyps, and further research is necessary to explore the potential role of phytoestrogens in the development of giant endometrial polyps.
