INTRODUCTION: Borderline ovarian tumors are typically indolent neoplasms. Since many are diagnosed in younger women, fertility conservation is an important consideration and has been advocated based on retrospective data. The objective of this study was to identify features impacting on recurrence and survival in a series of borderline ovarian tumors, and to assess the safety of a fertility-sparing approach. MATERIAL AND METHODS: A historical cohort study of consecutive borderline ovarian tumors cases treated at a single institution over 30 years (1981-2011)...

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...

Ovarian borderline tumors can show histologic features, such as different degrees of cellular proliferation, eosinophilic cells, autoimplants, and adenofibromatous architecture, the importance of which is not known. The aim of the study was to describe these features and correlate them with clinical characteristics. Eighty-three ovarian borderline tumors were studied for the aforementioned features. These were correlated with clinicopathologic features. Epithelial proliferation was associated with the T stage in serous tumors (P=0...

Aberrant histone methylation contributes to the progression and development of many tumors. Histone methylation is a dynamic process regulated by both histone demethylase and histone methyltransferase, which ultimately alters the levels of gene transcription. However, the relationship between histone demethylase and histone methyltransferase, as well as their regulatory mechanisms in ovarian cancer development, is still unclear. Lysine-specific demethylase 2B (KDM2B) is a key demethylase of H3K36me3 and H3K4me3 that regulates gene expression and plays a role in tumorigenesis via epigenetic mechanisms...

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...

Malignant transformation of the fallopian tube mucosa, followed by exfoliation of malignant cells onto ovarian and/or peritoneal surfaces, has been implicated as the origin of most pelvic high-grade serous carcinoma. Whether a parallel pathway exists for pelvic low-grade serous tumors [ovarian serous borderline tumor (SBT) and low-grade serous carcinoma (LGSC)] remains to be fully elucidated. The literature is challenging to interpret due to variation in the diagnostic criteria and terminology for cytologically low-grade proliferations of the fallopian tube mucosa, as well as variation in fallopian tube specimen sampling...

A 59-year-old woman with a remote history of invasive ductal carcinoma of the breast was found on a follow-up computed tomography scan of her brain to have a 1-cm lesion in the right frontal lobe in 2008. In the ensuing years, before her current admission, multiple imaging studies of the brain revealed that the lesion was stable and it was, therefore, interpreted as a small area of encephalomalacia related to a thrombosed cortical vein, a cavernoma, or treated metastatic breast cancer. In 2013, the patient underwent a bilateral salpingo-oophorectomy for ovarian tumors that were diagnosed as bilateral serous cystadenofibromas...

Krebs von den Lungen-6 (KL-6), a mucinous sialylated sugar chain on human mucin-1 glycoprotein (MUC1), is a diagnostic marker for interstitial lung diseases. Furthermore, elevated serum KL-6 levels have been observed in certain malignant tumor types of epithelial origin. The expression of MUC1 has been observed in patients with epithelial ovarian cancer (EOC) and is considered a potential therapeutic target. In the present study, KL-6 serum levels were investigated in patients clinically suspected of having malignant ovarian tumors...

OBJECTIVE: Recent studies suggest that mucinous borderline ovarian tumors (MBOTs) belong to a high-risk group that is more likely to develop an invasive recurrence. The objective is to determine these risk factors. METHODS: A monocentric retrospective review of all consecutive patients with intestinal-type MBOT diagnosed between 1993 and 2013. All tumors were evaluated by one pathologist without knowledge of clinical outcome. Extensive surgical staging and pathological tumor sampling (1 block/cm diameter in tumors <10 cm and 2 blocks/cm diameter in tumors >10 cm) were performed in all cases...

Brenner tumors (BT) are rare ovarian tumors encompassing benign, borderline, and malignant variants. While the histopathology of BTs and their clinical course is well described, little is known about the underlying genetic defects. We employed targeted next generation sequencing to analyze the mutational landscape in a cohort of 23 BT cases (17 benign, 2 borderline, and 4 malignant) and 3 ovarian carcinomas with transitional cell histology (TCC). Copy number variations (CNV) were validated by fluorescence in-situ hybridization (FISH) and quantitative PCR-based copy number assays...

Pseudomyxoma peritonei (PMP) is a rare disease that usually originates from mucinous neoplasms of the appendix and, less commonly, from extra-appendiceal tumors, but it may also be caused by synchronous primary mucinous tumors of the ovary and appendix. The current study discusses the case of a 73-year-old female who presented with progressively worsening indigestion and abdominal distension. Magnetic resonance imaging of the pelvis revealed a large cystic mass with a thin enhancing septa arising from the right ovary and ascites with scalloping of the liver surface...
