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 serous borderline tumor (SBT) to invasive low grade serous carcinoma (LGSC) remains largely unknown. While 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...

According to the new and reproducible grading system of the MD Anderson Cancer Center (MDACC), low grade serous cancer (LGSC) differs greatly from the commonly known high grade serous cancer (HGSC). Pathology speaking, LGSC has less mitotic index; the grade of nuclear atypia is low to intermediate. Genetically speaking, these tumors tend to show mutation in the mitogen-activated protein kinase (MAPK) pathway, mainly in the KRAS and BRAF genes, resulting in uncontrolled proliferation; however, it seems that the presence of this mutation might be related to a better prognosis compared to their absence...

BACKGROUND Paraovarian cysts are common and are generally benign; however, they are frequently misdiagnosed as being of ovarian origin. Conversely, paraovarian tumors of borderline malignancy are extremely rare. Especially, no cases of spontaneous rupture have been reported, and all previous reports had normal serum carbohydrate antigen (CA) 125 level. As for imaging findings, the presence of papillary projections in the lumen of paraovarian tumors does not always indicate malignancy or benignancy, which makes the preoperative distinction difficult...

BACKGROUND: Although ovarian fine-needle aspiration (FNA) cytology is not commonly used as a primary modality of diagnosis for patients with ovarian lesions, many ovarian cysts are aspirated intraoperatively and occasionally for diagnostic purposes. Therefore, the ability to interpret these specimens remains critical. Previous studies have suggested a high specificity but low sensitivity as a limitation. The objective of the current study was to further explore the use and performance of ovarian cyst FNA for diagnosing malignancy at the study institution...

Menstrual pain, a common gynecological condition, has been associated with increased risk of ovarian cancer in some, but not all studies. Furthermore, potential variations in the association between menstrual pain and ovarian cancer by histologic subtype have not been adequately evaluated due to lack of power. We assessed menstrual pain using either direct questions about having experienced menstrual pain, or indirect questions about menstrual pain as indication for use of hormones or medications. We used multivariate logistic regression to calculate the odds ratio (OR) for the association between severe menstrual pain and ovarian cancer, adjusting for potential confounders, and multinomial logistic regression to calculate odds ratios for specific histologic subtypes...

REVIEW
Karen Belkić, Dževad Belkić
Ovarian cancer is a major cause of cancer death among women worldwide, and particularly in Israel. Although the disease at stage IA has 5 year survival rates of over 90%, early detection methods are not sufficiently accurate. Consequently, ovarian cancer is typically diagnosed late, which results in high fatality rates. An excellent candidate for early ovarian cancer detection would be in vivo magnetic resonance spectroscopy (MRS) because it is non-invasive and free of ionizing radiation. In addition, it potentially identifies metabolic features of cancer...

OBJECTIVE: The aim of this study was to find the unfavorable prognostic factors for recurrence after fertility-preserving surgery (FPS) in patients with borderline ovarian tumors (BOTs). METHODS: To perform a meta-analysis to compare the recurrence rates of BOT patients after FPS according to different prognostic factors, we searched PubMed, EMBASE, and Cochrane for observational studies. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated with a fixed-effects model...

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...
