RAD51D is a key player in DNA repair by homologous recombination (HR) and RAD51D truncating mutation carriers have an increased risk for ovarian cancer (OC). However, the contribution of non-truncating RAD51D variants to cancer predisposition remains uncertain. Using deep sequencing and case-control genotyping studies, we show that in French Canadians, the missense RAD51D variant c.620C>T;p.S207L is highly prevalent and is associated with a high risk for ovarian high-grade serous carcinoma (HGSC) (3.8% cases vs 0...

Deepti Sharma, Garima Singh
Thrombocytosis has been suggested to be a poor prognostic indicator in malignancies. Studies have shown that thrombocytosis is associated with a poor prognosis in various gynecological malignancies such as carcinoma ovary, cervical cancer, and endometrial cancer. The aim of this study is to analyze the impact of thrombocytosis on the prognosis of gynecological cancer. All the relevant data were retrieved by PubMed, MEDLINE, and Web of Science, and then studies were chosen in this analysis of association between thrombocytosis and gynecological malignancy...

The gold standard for the detection of urothelial carcinoma is represented by urethro-cystoscopy and biopsy. Both procedures are invasive and expensive and therefore cytology is often used as first approach to investigate on a possible neoplasia, being a safe and cost-effective diagnostic modality of evaluation. Because cytology alone is not highly sensitive for detection of low grade urothelial carcinoma and recurrence of the disease, several adjunct markers and urine based tests for urothelial carcinoma have been developed, which can help in the final diagnosis...

Previous researchers obtained various apparent diffusion coefficient (ADC) cutoff values to differentiate endometrial carcinoma from benign mimickers with 1.5T magnetic resonance imaging (MRI). Few studies have used 3T MRI or validated the effectiveness of these cutoff ADC values prospectively. This study was designed in two stages to obtain a cutoff ADC value at 3T MRI and to validate prospectively the role of the ADC value. First, we conducted a retrospective study of 60 patients to evaluate the diagnostic value of ADC by obtain a theoretical cutoff ADC value for differentiating between benign and malignant endometrial lesions...

Long non-coding RNAs have previously been demonstrated to play important roles in regulating human diseases, especially cancer. However, the biological functions and molecular mechanisms of long non-coding RNAs in hepatocellular carcinoma have not been extensively studied. The long non-coding RNA CASC2 (cancer susceptibility candidate 2) has been characterised as a tumour suppressor in endometrial cancer and gliomas. However, the role and function of CASC2 in hepatocellular carcinoma remain unknown. In this study, using quantitative real-time polymerase chain reaction, we confirmed that CASC2 expression was downregulated in 50 hepatocellular carcinoma cases (62%) and in hepatocellular carcinoma cell lines compared with the paired adjacent tissues and normal liver cells...

The epithelial-mesenchymal transition is the key process driving cancer metastasis. MicroRNA-194 inhibits epithelial-mesenchymal transition in several cancers and its downregulation indicates a poor prognosis in human endometrial carcinoma. Self-renewal factor Sox3 induces epithelial-mesenchymal transition at gastrulation and is also involved epithelial-mesenchymal transition in several cancers. We intended to determine the roles of Sox3 in inducing epithelial-mesenchymal transition in endometrial cancer stem cells and the possible role of microRNA-194 in controlling Sox3 expression...

Endometrial carcinoma (EC) shows intertumor heterogeneity, with several different histologic types differing in their morphologic and molecular features. There is also intratumoral morphologic heterogeneity, with different neoplastic cell components within the same tumor, with different morphologic and molecular features. In this article, we discuss the consequences of tumor heterogeneity in EC at the morphologic and molecular levels, by describing some illustrative examples produced by the research team. They are (1) morphologic heterogeneity in conventional EC and mixed tumors, (2) EC with microsatellite instability, (3) branched evolution as shown by exome sequencing analysis, (4) morphologic, molecular, and metabolomic differences between the tumor surface and myometrial invasion front, (5) tumor heterogeneity at the microenviromental level, (6) the sensitivity of endometrial aspirates to detect tumor heterogeneity in EC, and (7) sampling strategies to detect tumor heterogeneity in hysterectomy specimens...

Previous studies have suggested that overexpression of the oncogenic protein epithelial membrane protein-2 (EMP2) correlates with endometrial carcinoma progression and ultimately poor survival from disease. To understand the role of EMP2 in the etiology of disease, gene analysis was performed to show transcripts that are reciprocally regulated by EMP2 levels. In particular, EMP2 expression correlates with and helps regulate the expression of several cancer stem cell associated markers including aldehyde dehydrogenase 1 (ALDH1)...

In endometrioid endometrial carcinomas (EEC), MELF (microcystic, elongated and fragmented) myoinvasion is associated with easily overlooked lymph node metastases; however, the role of immunohistochemistry in their detection and their clinical significance have not been addressed. We identified MELF in 43 of 101 (43%) myoinvasive EECs. Nodes were removed in 49 (49%), 25 with MELF and 24 without MELF. Metastases were initially reported in 3 of the former (12%) and 2 of the latter (8%). All negative nodes were reviewed and cytokeratin immunohistochemistry was performed...
