Background: Epithelial ovarian cancer (EOC) is often challenging to diagnose, even though histological examination. microRNA (miRNA or miRNA) is bound to the target messenger RNA (mRNA) and causing the mRNA molecules are silenced. The identification of miRNA expression-based EOC subtypes is considered a critical means of prognostication. So far, the studies on EOC subtypes have not been well characterized. Objective: This study aimed to confirm the existence of miRNAs in EOC and to assess their potential as clinical biomarkers for EOC. Methods: We sampled 25 ovarian tumor tissues from patients with human ovarian tumors (17 malignant; 12 serous EOC, five non-serous EOC, and eight benign ovarian tumors). miRNA microarray detection was performed to identify EOC miRNAs. Real-time PCR was adapted for the validation of differentially expressed miRNAs detected by microarray analysis was related to hybridization intensity. Results: The results confirmed that miRNAs exist in EOC, relative expression of EOC miRNAs demonstrated that upregulation of miR-483-5p, and downregulation of miR-127-3p, and miR-532-5p were significantly expressed in the malignant group than in the benign group at p ' 0.05. Besides, miR-483-5p could also distinguish EOC subtypes between serous EOC and non-serous EOC, with a p ' 0.05. Conclusion: A comprehensive miRNA expression profiling can help to refine subtype classification in EOC, opening new opportunities for identifying clinically applicable markers for improved stratification and diagnostics of ovarian tumors.

We aimed to develop a diagnostic model identifying ovarian cancer (OC) from benign ovarian tumors using metagenomic data from serum microbe-derived extracellular vesicles (EVs). We obtained serum samples from 166 patients with pathologically confirmed OC and 76 patients with benign ovarian tumors. For model construction and validation, samples were randomly divided into training and test sets in the ratio 2:1. Isolation of microbial EVs from serum samples of the patients and 16S rDNA amplicon sequencing were carried out. Metagenomic and clinicopathologic data-based OC diagnostic models were constructed in the training set and then validated in the test set. There were significant differences in the metagenomic profiles between the OC and benign ovarian tumor groups; specifically, genus Acinetobacter was significantly more abundant in the OC group. More importantly, Acinetobacter was the only common genus identified by seven different statistical analysis methods. Among the various metagenomic and clinicopathologic data-based OC diagnostic models, the model consisting of age, serum CA-125 levels, and relative abundance of Acinetobacter showed the best diagnostic performance with the area under the receiver operating characteristic curve of 0.898 and 0.846 in the training and test sets, respectively. Thus, our findings establish a metagenomic analysis of serum microbe-derived EVs as a potential tool for the diagnosis of OC.

Gonadotropins can stimulate ovarian cancer growth in cell cultures. Corresponding LH/hCG receptors have been demonstrated in ovarian cancer. However, reduction of elevated serum gonadotropins by GnRH analogs in ovarian cancer patients did not lead to growth restriction, which means that serum levels of gonadotropins may not play the most important role in ovarian cancer. We therefore analyzed the LH and FSH concentrations in cyst fluids of ovarian cancer. Patients with preoperatively diagnosed cystic ovarian tumors were eligible for the study. Serum samples of the patients were obtained during surgery, while the fluids within the cysts were aspirated after surgical removal of the tumor. FSH and LH levels in serum and cyst fluids were measured using single antibody EIA (Boehringer Mannheim GmbH, Germany). Cyst fluids and sera of 108 patients were evaluated. While there were no significant differences in the FSH and LH serum concentrations, highly significant differences in the FSH and LH levels in cyst fluids were found. Only cancer cysts contained FSH and LH, while the corresponding concentrations in benign cysts were always below the measuring range of the assays. This clear division between high gonadotropin levels in cysts of serous ovarian cancer and low or absent concentrations in benign ovarian tumors further supports the hypothesis that FSH and LH may play a role in ovarian cancer; however, explanations for this surprising finding are still lacking.

Background A need for follow-up recommendations for survivors of fallopian tube, primary peritoneal, or epithelial ovarian cancer after completion of primary treatment was identified by Cancer Care Ontario’s Program in Evidence-Based Care.Methods We searched for existing guidelines, conducted a systematic review (medline, embase, and cdsr, January 2010 to March 2015), created draft recommendations, and completed a comprehensive review process. Outcomes included overall survival, quality of life, and patient preferences.Results The Cancer Australia guidance document Follow Up of Women with Epithelial Ovarian Cancer was adapted for the Ontario context. A key randomized controlled trial found that the overall survival rate did not differ between asymptomatic women who received early treatment based on elevated serum cancer antigen 125 (ca125) alone and women who waited for the appearance of clinical symptoms before initiating treatment (hazard ratio: 0.98; 95% confidence interval: 0.80 to 1.20; p = 0.85); in addition, patients in the delayed treatment group reported good global health scores for longer. No randomized studies were found for other types of follow-up. We recommend that survivors be made aware of the potential harms and benefits of surveillance, including a discussion of the limitations of ca125 testing. Women could be offered the option of no formal follow-up or a follow-up schedule that is agreed upon by the woman and her health care provider. Education about the most common symptoms of recurrence should be provided. Alternative models of care such as nurse-led or telephone-based follow-up (or both) could be emerging options.Conclusions The recommendations provided in this guidance document have a limited evidence base. Recommendations should be updated as further information becomes available.

Abstract Context: Total inhibin is the sum of precursors, subunits, and mature molecules of inhibin, which the normal ovary nearly stops to produce after menopause, whereas ovarian tumors still release. Objective: The aim of the present study was to evaluate whether the serum concentration of total inhibin has the sensitivity/specificity characteristics to become a diagnostic test for epithelial ovarian cancer in postmenopausal women. Design: This was a controlled, cross-sectional study. Setting: The study was conducted at the University of Siena. Patients: Blood specimens were collected from postmenopausal women with: 1) epithelial ovarian cancer, stage II-III (n = 89); 2) benign ovarian tumors (n = 25); 3) breast (n = 10), colon (n = 10), and stomach (n = 10) cancers; and 4) controls (n = 95). In the group of women with epithelial ovarian cancer, blood specimens were also collected after surgical removal of the tumor. In four cases of women with stage IIC mucinous tumor, blood specimens were collected during the follow-up time. Intervention: Total inhibin was measured by a new double-antibody ELISA. Results: Women with epithelial ovarian cancers showed serum total inhibin levels significantly higher than those with benign tumor or with nonovarian tumors or controls (P < 0.001). Patients with serous (n = 40) or mucinous tumors (n = 17) showed the highest total inhibin levels (P < 0.001). At 95% specificity, the total inhibin assay detected 37 of 40 (93%) serous tumors and 16 of 17 (94%) mucinous tumors. When total inhibin was combined with CA-125, all cases of serous and mucinous tumors were detected, and the overall sensitivity for epithelial ovarian cancers was 99% at 95% specificity. A significant decrease of total inhibin levels was shown in women with serous and mucinous carcinoma as result of surgery (P < 0.001). In the four women who were followed up, recurrence was associated to an increase of total inhibin levels. Conclusions: The present data show that total inhibin is a sensitive and specific marker of epithelial ovarian cancers in postmenopausal women. Total inhibin may therefore be combined with CA-125 for noninvasive diagnosis of epithelial ovarian cancer and may also be a useful serum marker to monitor disease-free intervals.

The aim of this work was to compare mean concentrations of gonadotropins in serum and fluid from malignant and benign ovarian tumors. We enrolled 126 patients diagnosed with malignant epithelial tumors (n=40), borderline epithelial tumors (n=14), benign cystadenomas (n=28) and simple cysts (n=44) of the ovary. Premenopausal and postmenopausal subgroups were formed in each group. The concentration of FSH and LH was measured in serum and tumor fluid and the serum/tumor fluid ratio was calculated. The results in each group were compared and the sensitivity, specificity, positive and negative predictive values were determined. Mean concentrations of both gonadotropins in ovarian cancer fluid were significantly higher than in the remaining groups (P ranged from <0.005 to <0.0001). Mean serum/fluid ratios were lowest in ovarian cancer (FSH=2.91, LH=4.19). Our findings support the hypothesis that gonadotropins are involved in ovarian carcinogenesis and suggest that gonadotropin serum/tumor fluid ratios could be of value in the differential diagnosis of functional and organic cysts of the ovary.
