OBJECTIVE: Gynecologists occasionally encounter synchronous endometrial and ovarian endometrioid carcinoma (SEO-EC) patients who show favorable prognosis than locally advanced or metastatic disease patients. This study aimed to elucidate prognostic factors of SEO-EC and identify patients who have a sufficiently low risk of recurrence without receiving adjuvant chemotherapy. METHODS: We retrospectively reviewed 46 patients with pathologically confirmed SEO-EC who underwent surgery at the National Cancer Center Hospital between 1997 and 2016...

We here describe a case report of a positive precaval sentinel lymph node with negative pelvic sentinel lymph node in a patient with endometrial cancer. A 45-years-old woman was diagnosed with a grade 2 endometrioid carcinoma of the endometrium. She was treated with a hysterectomy and bilateral salpingo-oophorectomy, associated with dissection of sentinel lymph nodes (SLNs). We detected bilateral external and common bilateral iliac nodes and one precaval node. At pathological examination the pelvic nodes were non-metastatic, but the precaval node was positive...

Cancers of the reproductive organs have a strong association with mitochondrial defects, and a deeper understanding of the role of this organelle in preneoplastic-neoplastic changes is important to determine the appropriate therapeutic intervention. Mitochondria are involved in events during cancer development, including metabolic and oxidative status, acquisition of metastatic potential, resistance to chemotherapy, apoptosis, and others. Because of their origin from melatonin-producing bacteria, mitochondria are speculated to produce melatonin and its derivatives at high levels; in addition, exogenously administered melatonin accumulates in the mitochondria against a concentration gradient...

OBJECTIVE: Mutational signatures provide insights into the biological processes shaping tumor genomes and may inform patient therapy. We sought to define the mutational signatures of i) endometrioid and serous endometrial carcinomas (ECs), stratified into the four molecular subtypes, ii) uterine carcinosarcomas, and iii) matched primary and metastatic ECs. METHODS: Whole-exome sequencing MC3 data from primary endometrioid and serous carcinomas (n = 232) and uterine carcinosarcomas (n = 57) from The Cancer Genome Atlas (TCGA), and matched primary and metastatic ECs (n = 61, 26 patients) were reanalyzed, subjected to mutational signature analysis using deconstructSigs, and correlated with clinicopathologic and genomic data...

Synchronous endometrial and ovarian cancer (SEOC) is a rare entity among gynecological cancers, which exhibits endometrioid histology in its early stages and generally has a good prognosis. However, diagnosis is difficult and recent reports have demonstrated that most clinically diagnosed cases of SEOC have clonally related cancers, indicating metastatic cancer. The association of SEOC with Lynch syndrome is also not clearly understood. We herein present the case of a 41-year-old SEOC patient with MSH2 mutation...

We have identified nine highly connected and differentially expressed gene subnetworks between aggressive primary tumors and metastatic lesions in endometrial carcinomas. We implemented a novel pipeline combining gene set and network approaches, which here allows integration of protein-protein interactions and gene expression data. The resulting subnetworks are significantly associated with disease progression across tumor stages from complex atypical hyperplasia, primary tumors to metastatic lesions. The nine subnetworks include genes related to metastasizing features such as epithelial-mesenchymal transition (EMT), hypoxia and cell proliferation...

Endometrial cancer (EC) is one of the most frequently diagnosed cancers in women, and despite recent therapeutic advances, in many cases, treatment failure results in cancer recurrence, metastasis, and death. Current research demonstrates that the interactive crosstalk between two discrete cell types (tumor and stroma) promotes tumor growth and investigations have uncovered the dual role of the stromal cells in the normal and cancerous state. In contrast to tumor cells, stromal cells within the tumor microenvironment (TME) are genetically stable...

PURPOSE: Vaginal brachytherapy reduces the risk of local recurrence and was shown to be equieffective in preventing vaginal vault recurrence, but less toxic compared to external-beam radiotherapy in a subset of high intermediate-risk endometrial cancer patients and is administered as single adjuvant treatment in those patients. Different radiotherapeutic approaches with various dosing schemes exist toward brachytherapy. The aim of this study was to compare the outcome and long-term quality of life after brachytherapy with two different high-dose-rate dosing schemes...

Carcinoma-associated mesenchymal stem cells (CA-MSCs) are critical stromal progenitor cells within the tumor microenvironment (TME). We previously demonstrated that CA-MSCs differentially express bone morphogenetic protein family members, promote tumor cell growth, increase cancer "stemness," and chemotherapy resistance. Here, we use RNA sequencing of normal omental MSCs and ovarian CA-MSCs to demonstrate global changes in CA-MSC gene expression. Using these expression profiles, we create a unique predictive algorithm to classify CA-MSCs...

OBJECTIVE: A subset of endometrial cancer is characterized by deficiencies in the mismatch repair (MMR) pathway. MMR testing is a well-established tool to screen for Lynch syndrome, but has also become a companion diagnostic test for immunotherapy. We compared the MMR status of primary and paired metastatic endometrial cancer to determine whether MMR deficiency can occur specifically in advanced endometrial cancer compared to primary tumor. METHODS: Matched primary uterine and metastatic endometrioid adenocarcinoma from 2009 to 2018 at our institution were identified...

Endometrial cancer is the most common gynecologic cancer in women today. It is surgically staged, and while surgery is the primary treatment modality, the identification of disease extent-in particular extrauterine spread-prior to surgery is important to optimize treatment decision making. Ultrasound and MRI are useful for evaluating the extent of local disease, while CT and PET are used for detecting lymph node or distant metastases. Diffusion-weighted MRI has also been used for detecting small metastatic deposits in lymph nodes and omentum...

INTRODUCTION: Onapristone is a type I progesterone receptor (PR) antagonist, which prevents PR- mediated DNA transcription. Onapristone is active in multiple preclinical models and two prior studies demonstrated promising activity in patients with breast cancer. We conducted a study of extended release (ER) Onapristone to determine a recommended dose and explore the role of transcriptionally-activated PR (APR), detected as an aggregated subnuclear distribution pattern, as a predictive biomarker...

INTRODUCTION AND HYPOTHESIS: The treatment of pelvic organ prolapse (POP) in elderly women can be challenging. The vaginal operation known as colpocleisis, the total occlusion of the urogenital hiatus, with concomitant hysterectomy was described by Rouhier and represents a safe, time-saving, and reproducible procedure in the case of POP associated with uterine pathological conditions. It is suitable for elderly women who do not require preservation of coital function. The objective of this video is to provide anatomical illustrations and a precise description of the surgical steps...

According to the sentinel node biopsy (SNB), systematic pelvic lymph node dissection (PLND) may not be needed for patients with early-stage endometrial cancer. On the other hand, imaging technology including fluorodeoxyglucose-positron emission tomography/computed tomography (FDG PET/CT) has been developing worldwide. The aim of this study was to evaluate the combined diagnostic accuracy of FDG PET/CT and SNB in the prediction of pelvic lymph node metastasis in endometrial cancer patients.One hundred twenty-one patients with endometrial cancer underwent FDG PET/CT before hysterectomy and received SNB followed by systematic PLND...

Uterine serous carcinoma (USC) represents an aggressive histologic subtype of endometrial cancer. It is associated with a poor prognosis, and improved therapies for women battling USCs are greatly needed. ONC201 is an orally bioavailable, first-in-class small molecule that induces tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) independent of p53. ONC201 has demonstrated anti-tumorigenic activity in pre-clinical models of solid tumors through induction of apoptosis and inactivation of the AKT/MAPK pathways...

The level of copy number alteration (CNA), termed CNA burden, in the tumor genome is associated with recurrence of primary prostate cancer. Whether CNA burden is associated with prostate cancer survival or outcomes in other cancers is unknown. We analyzed the CNA landscape of conservatively treated prostate cancer in a biopsy and transurethral resection cohort, reflecting an increasingly common treatment approach. We find that CNA burden is prognostic for cancer-specific death, independent of standard clinical prognosticators...

BACKGROUND: Accurate identification of sentinel lymph nodes in patients with cancer improves detection of metastatic disease and decreases surgical morbidity. We sought to establish whether indocyanine green fluorescent dye is non-inferior to isosulfan blue dye in detecting sentinel lymph nodes in women with cervical and uterine cancers. METHODS: In this non-inferiority, within-patient comparison study, patients aged 18 years or older with clinical stage I endometrial or cervical cancer undergoing curative surgery were randomly assigned 1:1 to lymphatic mapping with isosulfan blue dye (visualised by white light) followed by indocyanine green (visualised by near-infrared imaging), or indocyanine green followed by isosulfan blue dye...
