OBJECTIVE: To estimate the frequency of occult endometrial cancer in women undergoing hysterectomy for benign indications. STUDY DESIGN: We performed a retrospective review of all patients undergoing hysterectomies for benign indications at our institution from 2006 to 2014. A departmental database was used to identify all hysterectomies performed, and institutional tumor registry was used to identify cases of endometrial carcinoma. Occult carcinomas were defined as cases with no suspicion preoperatively and histopathologic diagnosis of endometrial cancer postoperatively...

Synchronous endometrial and ovarian malignancies occur in 5% of women presenting with endometrial cancer and 10% of patients presenting with ovarian malignancy. When a high-grade serous carcinoma concurrently involves both ovary and endometrium, pathological determination of whether they are synchronous primaries or metastatic tumors from one primary site can be challenging. MicroRNAs (miRNA) are 22-nucleotide noncoding RNAs that are aberrantly expressed in cancer cells and may inherit their cellular linage characteristics...

Endometrial hyperplasia (EH) is a pathological condition characterised by hyperplastic changes in endometrial glandular and stromal structures lining the uterine cavity. Endometrial hyperplasia, particularly with atypia, is a significant clinical concern because it can be a precursor of endometrial cancer. Accurate diagnosis of precancerous lesions of the endometrium and exclusion of coexisting endometrial carcinomas are absolutely required for the optimal management of patients. The classification of endometrial hyperplasia has had numerous terminology...

Chemo-radiation represents an effective therapy for carcinoma of the uterine cervix. The endometrium may however receive a consistent dose of mutagenic radiations and patients may have an increased risk of secondary malignancies. Endometrial mixed malignant mullerian tumor (MMMT) is a rare, highly aggressive disease, and neuroendocrine features are even rarer. A 68 years old woman underwent radio-chemotherapy for a squamous cell carcinoma of the cervix. Follow up was uneventful until, eight years after radio-chemotherapy, imaging exams detected a diffuse enlargement of the uterine body...

Benign proliferations that mimic malignancies are commonly encountered during the course of assessment of small and fragmented endometrial samples. Although benign, endometrial epithelial metaplasias often coexist with premalignant or malignant lesions causing diagnostic confusion. The difficulty with mucinous metaplasia lies in its distinction from atypical mucinous glandular proliferations and mucinous carcinomas, which are associated with significant interobserver variability. Papillary proliferation of the endometrium is commonly associated with hormonal drugs and endometrial polyps and is characterised by papillae with fibrovascular cores covered by epithelial cells without cytologic atypia...

Endometrial carcinoma is a malignant epithelial tumor that forms in the inner lining, or endometrium, of the uterus. Endometrial carcinoma is the most common gynecologic malignancy. Approximately two-thirds of endometrial carcinoma cases are diagnosed with disease confined to the uterus. The complete NCCN Guidelines for Uterine Neoplasms provide recommendations for the diagnosis, evaluation, and treatment of endometrial cancer and uterine sarcoma. This manuscript discusses guiding principles for the diagnosis, staging, and treatment of early-stage endometrial carcinoma as well as evidence for these recommendations...

OBJECTIVES: Uterine serous carcinoma (USC) involving an endometrial polyp and concurrent extrauterine disease is associated with poor prognosis. We examined the clinicopathological profiles of patients with stage 1A USC with and without polyp involvement and the role of polyp size and lymphovascular invasion (LVI) as prognostic indicators for extrauterine disease in patients with early USC. METHODS/MATERIALS: From 2002 to 2014, 242 patients with pure USC were identified...

OBJECTIVE: In 2014 World Health Organization criteria, seromucinous carcinoma was defined as a new histological subtype in ovarian carcinomas, but "seromucinous carcinoma" was not defined in endometrial carcinomas. The aim of this study was to identify seromucinous carcinoma resembling ovarian seromucinous carcinoma in endometrial carcinomas, and to evaluate the clinical significance for prognoses of the patients. METHODS: Central pathological review was conducted for patients with endometrioid carcinoma of the endometrium treated by primary surgery at our hospital between 1990 and 2013...

Endometrial cancer is the most prevalent gynecological cancer in occident and the third most common cancer among women in Tunisia. It is dominated by carcinoma. The identification of prognostic factors allows a better understanding of its outcome and guides its therapeutic approach. We propose to describe the clinicopathological features and identify the histoprognostic factors of this cancer. It is a retrospective analysis of a series of 62 total hysterectomy specimens with bilateral salpingo-oophorectomy from women with primary carcinoma of the endometrium, colligated in Anatomy Laboratory and Pathology Salah Azaiz Institute of Tunis over a period of 5 years, from January 2003 to December 2007...

Lynch syndrome is an autosomal dominant syndrome that can be subdivided into Lynch syndrome I, or site-specific colonic cancer, and Lynch syndrome II, or extracolonic cancers, particularly carcinomas of the stomach, endometrium, biliary and pancreatic systems, and urinary tract. Lynch syndrome is associated with point mutations and large rearrangements in DNA MisMatch Repair (MMR) genes. This syndrome shows a variable phenotypic expression in people who carry pathogenetic mutations. So far, a correlation in genotype-phenotype has not been definitely established...

Accurate staging of cancers is an important determinant of prognosis and guides optimal patient treatment. Although the International Collaboration on Cancer Reporting recommends that endometrial cancers (including carcinosarcomas) are pathologically staged using the International Federation of Gynecology and Obstetrics (FIGO) 2009 system, in many areas TNM [American Joint Committee on Cancer (AJCC) or Union for International Cancer Control (UICC)] staging is used or even mandated; these latter systems are based on FIGO 2009...

Endometriosis is a risk factor for type I epithelial ovarian cancer but an issue to be clarified is the site of origin of endometriosis associated ovarian cancer. Here we proposed that the uterus may be the organ of origin of ovarian endometrioid cancer associated with endometriosis. Thus, the first neoplastic transformation would characterize the uterine cells migrating in the pelvis via retrograde menstruation and they would implant secondarily on the ovary. Supporting this hypothesis, an higher incidence of synchronous precancerous and cancerous endometrial pathology in patients affected by ovarian endometrioid cancer associated with endometriosis was showed...

Background/aim: The vanishing cancer phenomenon was first reported in radical prostatectomy specimens in the absence of neo-adjuvant treatment. Reported cases are mostly well-differentiated and low-volume tumors. A similar entity was described for hysterectomy specimens of patients with biopsy proven endometrial cancer (EC). In this study, we discuss the probable reasons for vanishing EC and long-term follow-up results of EC patients without residual tumors in hysterectomy specimens. Materials and methods: This study was carried at two institutions in Ankara, Turkey, in a retrospective design...

Lung adenocarcinoma (LADC)is a general form of non-small cell lung cancer that represents a significant threat to public health worldwide. The 5-year-survival rate for LADC is currently below 15%. The transcription factor KLF15, also called kidney-enriched KLF (KKLF), has been proven to play a role in inhibiting proliferation and diversification of carcinoma cells, including those of the endometrium, pancreas and breast, but the involvement of KLF15 in LADC has not previously been studied. In this study, we compared the in vitro expression of KLF15 in human LADC tissues and adjacent normal lung tissues...
