Ovarian cancer is a major gynaecological cancer with different subtypes and studies have suggested that estrogen receptor (ER) or progesterone receptor (PR) positivity are associated with better clinical outcomes. Furthermore, the clinical outcomes of ovarian cancer are better in Asian compared to Caucasian. To date, studies investigating the ER or PR positivity in all subtypes of ovarian cancer, including borderline epithelial, are limited. In this retrospective study we investigated ER and PR positivity in Chinese women with malignant epithelial ovarian cancer (n=577), sex cord-stromal tumor (n=26) and borderline epithelial ovarian cancer (n=98) taking into account menopausal status...

The incidence of ovarian cancer depends on the ethnicity and geographical area. Menopausal status is a well-known risk factor for ovarian cancer and most cases occur after menopause in Caucasians. However, it is less clear how the status of menopause or age at diagnosis is associated with ovarian cancer including its subtypes in Chinese women. Data on 1,283 women with primary malignant or borderline ovarian cancer including age at diagnosis, age at menopause and histology from the largest women's hospital in China was analysed...

Ovarian cancer is the fifth most common cancer in women worldwide and has the highest mortality amongst gynecological cancers. miRNAs are a class of non-coding RNAs, approximately 22 nt long, that negatively regulate gene expression and to have roles in cell growth, differentiation, metabolism, apoptosis and tumorigenesis. Dysregulated miRNA-223 expression has been implicated in a wide range of cancer subtypes. SMARCD1 is an integral protein component of the SWI/SNF complex which remodels chromatin, and which has important roles in transcriptional control, DNA replication, recombination and repair...

Hedgehog signaling pathway has been implicated in the pathology of ovarian cancer, and Survivin (BIRC5) has been suggested as a novel target of this pathway. Herein we investigated the role of Hedgehog signaling pathway and Survivin in ovarian carcinoma and borderline tumor samples. We aimed to determine possible ways of pathway modulation on primary ovarian cancer cells and an established cell line. RNA was extracted from fresh tumors and control tissues and gene expression was examined using qRT-PCR. Pathway activity in cell lines was examined after treatment with cyclopamine, SHH protein, GANT-61 or lithium chloride using qRT-PCR, western blot and confocal microscopy...

BACKGROUND: In the intraoperative consultation of ovarian tumors, the histological diagnosis of frozen sections (FS) of large tumors is frequently difficult because of the limited number of tumor samples. The application of imprint cytology (IC), in which samples are obtained from wide areas of the tumors, is useful for intraoperative consultation. However, the useful aspects of IC have not been clearly defined. The present study is a detailed comparison of IC and FS that clearly defines the useful aspects of IC...

In contrast to non-invasive extraovarian implants, invasive implants of ovarian serous borderline tumor/atypical proliferative serous tumor are associated with adverse outcome and have been reclassified as low-grade serous carcinoma. Mutations of KRAS and/or BRAF have been reported in up to 50% of serous borderline tumor/atypical proliferative serous tumor. We investigated KRAS and BRAF mutation frequencies in the two types of implants of serous borderline tumor/atypical proliferative serous tumor in correlation with clinical outcome...

Highly upregulated in liver cancer (HULC) is a long noncoding RNA (lncRNA), which has recently been identified as a key regulator in the progression of hepatocellular carcinoma, gliomas and gastric cancer. However, its role in epithelial ovarian carcinoma (EOC) remains unknown. In this study, HULC expression was examined in EOC, borderline and benign ovarian tumors, and normal ovarian tissues by RT-PCR. Ovarian cancer cell phenotypes, as well as autophagy-associated proteins were examined after HULC overexpression or downregulation by plasmid or small interfering RNA (siRNA) transfection, respectively...

Epithelial ovarian neoplasms are a heterogeneous group of tumors, including various malignancies with distinct clinicopathologic and molecular features. Mutations in BRAF and KRAS genes are the most frequent genetic aberrations found in low-grade serous ovarian carcinomas and serous and mucinous borderline tumors. Implementation of targeted therapeutic strategies requires access to highly specific and highly sensitive diagnostic tests for rapid determination of mutation status. One candidate for such test is fully integrated, real-time polymerase chain reaction-based Idylla™ system for quick and simple detection of KRAS mutations in formaldehyde fixed-paraffin embedded tumor samples...

OBJECTIVE: The cell of origin of ovarian low-grade serous carcinoma (LGSC) remains unclarified. Our recent morphologic and immunophenotypic study suggests that most LGSCs may be derived from the fallopian tube. The purpose of the current study was to gain further insight into the origin of LGSC at the molecular level. METHODS: RNA-seq analysis was performed on a total of 31 tissue samples including LGSC (n=6), serous borderline tumors (SBT, n=6), fallopian tube epithelia (FTE, n=5), ovarian surface epithelia (OSE, n=4), and human peritoneal mesothelia (HPM, n=4)...

Borderline ovarian tumors (BOTs) represent an independent group among ovarian malignancies, being diagnosed at clinical stage earlier than invasive ovarian carcinomas (OCs) and characterized by a rather favorable outcome after careful surgical management. Data published worldwide showed a substantial discordance of p53 expression in BOTs. The purpose of this work was to present the current status of knowledge on the significance of TP53 gene and p53 protein product alterations in BOTs. In general, higher p53 expression patterns were reported for ovarian malignancies compared to BOTs...

Activating mutations involving the members of the RAS signaling pathway, including KRAS, NRAS, and BRAF, have been reported in ovarian low-grade serous carcinoma and its precursor lesion, serous borderline tumor (SBT). Whether additional genetic alterations in the RAS oncogene family accumulate during the progression of SBT to invasive low-grade serous carcinoma (LGSC) remains largely unknown. Although mutations of KRAS and BRAF occur at a very early stage of progression, even preceding the development of SBT, additional driving events, such as NRAS mutations, have been postulated to facilitate progression...

Mesonephric carcinomas are rare adenocarcinomas of the female genital tract that occur most commonly in the uterine cervix. They are classically thought to arise from benign mesonephric remnants, and are rarely reported at other sites in the gynecologic tract. Here we present an interesting biphenotypic ovarian adenocarcinoma with intimately associated but distinct components of both low-grade serous carcinoma and mesonephric-like carcinoma. A serous borderline tumor was present adjacent to the invasive carcinoma, and no benign mesonephric precursors were identified...

OBJECTIVE: Primary ovarian mucinous tumors progress from benign adenoma to borderline tumors to invasive mucinous carcinoma. A proper differential diagnosis is crucial to discriminate malignancies at the early stages of disease. However, few biomarkers are clinically available. We designed this study to analyze the clinical application of the oncogene IMP3 in monitoring early malignancies in ovarian primary mucinous tumors. METHODS: We collected 250 samples of ovarian primary mucinous tumors along with the corresponding clinicopathological information between 2009 and 2015 at the Gynecology and Obstetrics Hospital of Fudan University and performed immunochemical assays...

Focal micropapillary features in invasive urothelial carcinoma is sometimes difficult to distinguish from retraction artifact morphologically. Cell polarity reversal has been demonstrated in micropapillary tumors by epithelial membrane antigen (EMA) immunostaining. We have previously described the use of E-cadherin as a cell polarity marker in ovarian micropapillary serous borderline tumors. The aim of this study was to evaluate the utility of immunohistochemistry for EMA and E-cadherin in differentiating micropapillary urothelial carcinoma from retraction artifact...

Brenner tumor is a rare ovarian neoplasm that is seen in women of the fifth to sixth decade. Classified as benign, borderline, and malignant, these tumors may be associated with estrogen production, thus altering the estrogen-progesterone ratio. High estrogen stimulates the endometrium and this is responsible for producing various pathologies, namely, hyperplasia, atypia, and carcinoma. Very few case reports have been published highlighting the same. A case report is being presented here of a coexisting Brenner tumor and well-differentiated endometrial carcinoma in a 55-year-old nulliparous postmenopausal woman...
