Endometrial carcinoma is one of the most frequently diagnosed cancers in females. Long non-coding RNAs (lncRNAs) have been associated with cancer; its role in endometrial carcinoma is an emerging area of research. In this article, lncRNA TDRG1 expression in human endometrial carcinoma tissues and normal endometrial tissues was quantified by qRT-PCR. LncRNA TDRG1 was overexpressed or knocked-down in neither HEC-1B nor Ishikawa endometrial carcinoma cells, respectively, to assess cellular phenotype and expression of related molecules...

Endometrial carcinoma is the fourth most common cancer affecting women in the UK. Its most frequent sites of spread are to the pelvic and para-aortic lymph nodes, vagina and peritoneum. We report a case of a 63-year-old woman with known endometrial cancer who presented with left facial swelling and eye displacement. Investigations revealed an expansile soft-tissue density mass arising within the bone, centred on the left zygoma, with exophytic extension into the left maxillary antrum, infratemporal fossa and inferiorly into the orbit...

RATIONALE: Multiple primary malignancies can occur in the same organ or in multiple organs or systems. Likewise, they can occur simultaneously or successively. Based on the timing of the diagnosis, they are classified as multiple synchronous (i.e., concurrent) or metachronous (i.e., successive) primary malignancies. The vast majority of patients have multiple metachronous malignant tumors; multiple synchronous tumors are rare. PATIENT CONCERNS: A 63-year-old woman presented with the chief complaint of vaginal fluid discharge for 3 months and abdominal pain for 1 month...

The aim of the study was to investigate whether the tumor free distance (TFD), which is the distance in millimeters between the deepest point of invasion and the serosal surface, and absolute depth of invasion (DMI), the distance in millimeters between the endomyometrial junction and the deepest point of myometrial invasion, are useful in surgical staging and in predicting prognosis. The present study retrospectively analyzed 62 cases of endometrial carcinoma with complete surgical staging, carried out over a 4 and half-year period (January 2003 to June 2007)...

Developmental exposure to estrogenic chemicals is an established risk factor for cancer of the female reproductive tract. This increase in risk has been associated with disruption of normal patterns of cellular differentiation during critical stages of morphogenesis. The goal of this study was to document uterine epithelial phenotypes over time following neonatal treatment with the synthetic estrogen diethylstilbestrol (DES) or the soy phytoestrogen genistein (GEN) in female CD-1 mice. Both DES and GEN induced three distinct populations of abnormal endometrial epithelial cells: luminal (SIX1+/P63-/CK14-/CK18+), basal (SIX1+/P63+/CK14+/CK18-), and mixed/bipotential (SIX1+/P63-/CK14+/CK18+), which were all established by early adulthood...

We are reporting a case of endometrial lymphoepithelioma-like carcinoma (LELC) in a 63-year-old female. Microscopically, the tumor consisted of groups of tumor cells surrounded by dense lymphoplasmacytic infiltrate. Immunohistochemically, the tumour cells were positive for cytokeratins AE1/AE3, EMA, PAX8, p16, and estrogen receptors. Protein p53 showed an aberrant type of expression. Molecular genetic analysis revealed mutations in the TP53 and PIKP53CA genes. Based on our results, we believe that the tumor represents an unusual morphological variant of endometrial serous carcinoma...

OBJECTIVE: To evaluate the cost-utility of three lymphadenectomy strategies in the management of low-risk endometrial carcinoma. METHODS: A decision analysis model compared three lymphadenectomy strategies in women undergoing minimally invasive surgery for low-risk endometrial carcinoma: 1) routine lymphadenectomy in all patients, 2) selective lymphadenectomy based on intraoperative frozen section criteria, and 3) sentinel lymph node mapping. Costs and outcomes were obtained from published literature and Medicare reimbursement rates...

RATIONALE: Small cell carcinoma of the ovary (SCCO) is a rare and aggressive extra-pulmonary variant of small cell tumors of uncertain histogenesis. The pathogenesis and optimal treatment of SCCO is unclear. We present a very rare case of a synchronous primary ovarian small cell carcinoma and endometrioid adenocarcinoma of the uterus in a patient after 2 years of tamoxifen treatment for breast cancer. This is the first such report in the English literature. PATIENT CONCERNS: A 46-year-old woman had a history of left breast cancer that was treated with a simple mastectomy and sentinel lymph node biopsy in 2013...

The current lack of an accurate, cost-effective and non-invasive test that would allow for screening and diagnosis of gynaecological carcinomas, such as endometrial and ovarian cancer, signals the necessity for alternative approaches. The potential of spectroscopic techniques in disease investigation and diagnosis has been previously demonstrated. Here, we used attenuated total reflection Fourier-transform infrared (ATR-FTIR) spectroscopy to analyse urine samples from women with endometrial (n = 10) and ovarian cancer (n = 10), as well as from healthy individuals (n = 10)...

P-REX2a is a PTEN inhibitor that also activates Rac 1. No associations with P-REX2a and human endometrial cancers have been reported to date. In this study, we immunohistochemically analyzed 155 uterine endometrial malignancies for P-REX2a expression. The P-REX2a-positive tumors displayed worse prognosis independent of PTEN expression. Then, we transduced either P-REX2a expression vector or short hairpin RNAs targeting P-REX2a into 2 uterine endometrioid carcinoma cell lines, OMC-2 and JHUEM-14. Ectopic expression of P-REX2a led to increased cell proliferation only in the PTEN-expressing OMC-2 cells but did not show any change in the PTEN-negative JHUEM-14 cells or the P-REX2a-knockdown cells...

Primary endometrial squamous cell carcinoma is an extremely rare tumor that tends to occur in postmenopausal women. We report on a 33-year-old woman who presented with a history of irregular vaginal bleeding for more than 2 years, and a vaginal mass for more than 1 month. Biopsy of the vaginal mass revealed an invasive poorly differentiated squamous cell carcinoma. The patient underwent radical hysterectomy, bilateral salpingo-oophorectomy, omentectomy, pelvic lymph node dissection, peritoneal sampling and vaginal tumor resection...
