Of the trials that contain malignant ovarian serous tumor as an inclusion criterion, 1 is phase 1 (1 open), 2 are phase 2 (2 open), 1 is phase 2/phase 3 (1 open), and 1 is phase 3 (1 open). BRCA1 and BRCA2 are the most frequent gene inclusion criteria for malignant ovarian serous tumor clinical trials [3]. ...
The TP53 gene mutation frequency in ovarian serous carcinomas has been reported to range between 50% and 80%. A research team working at the The Sidney Kimmel Comprehensive Cancer Center of The Johns Hopkins Medical Institutions (Johns Hopkins) made several important findings regarding TP53 gene mutations with respect to high grade ovarian serous carcinoma, as reported in the International Journal of Gynecological Cancer. Ovarian serous carcinoma is the most common tumor subtype within the epithelial ovarian cancer histological classification.. According to the Johns Hopkins research team, a stringent analysis of the TP53 gene using purified epithelial tumor samples has not been performed to accurately assess the TP53 gene mutation frequency and its correlation to tumor histologic grade. The research team assessed the TP53 gene mutational profile in a relatively large series of high-grade (53 primary tumors and 18 recurrent tumors) and 13 low-grade ovarian serous tumors. All samples were ...
TY - JOUR. T1 - Gene expression analysis identifies two groups of ovarian high-grade serous carcinomas with different prognosis. AU - Espinosa, Inigo. AU - Catasus, Lluis. AU - Canet, Belén. AU - DAngelo, Emanuela. AU - Mũoz, Josefina. AU - Prat, Jaime. PY - 2011/6/1. Y1 - 2011/6/1. N2 - Gene expression profiling is an important tool to evaluate genetic heterogeneity in carcinomas and is useful to develop expression-based classifications for many types of cancer, as well as markers of disease outcome. In this study, we have investigated the expression profile of 22 genes involved in the PI3K-AKT pathway in 26 high-grade ovarian carcinomas (19 serous and 7 clear cell carcinomas). Unsupervised hierarchical clustering divided high-grade ovarian carcinomas into three groups. Although all clear cell carcinomas clustered in one group, high-grade serous carcinomas were segregated into two separate groups with different prognosis (P=0.05). High expression of CASP3, XIAP (X-linked inhibitor of ...
The TP53 mutation frequency in ovarian serous carcinomas has been reported to range between 50% and 80%, but a stringent analysis of TP53 using purified epithelial samples has not yet been performed to accurately assess the mutation frequency and to correlate it with the histologic grade. The purpose of this study was to assess the TP53 mutational profile in a relatively large series of high-grade (53 primary and 18 recurrent) and 13 low-grade ovarian serous tumors using DNA isolated from affinity-purified tumor cells and to correlate it with in vitro drug resistance. All samples were affinity purified, and the tumor DNA was analyzed for TP53 mutations in exons 4-9. In vitro drug resistance assays to carboplatin, cisplatin, paclitaxel, and taxotere were performed on the same tumor samples and correlated with the TP53 mutation status. TP53 mutations were detected in 57 (80.3%) of 71 high-grade carcinomas and in one (7.8%) of 13 low-grade serous tumors (an invasive low-grade serous carcinoma). The ...
Dishevelled family proteins (DVL1, DVL2 and DVL3) are cytoplasmic mediators involved in canonical and non-canonical Wnt signaling that are important for embryonic development. Since Wnt signaling promotes cell proliferation and invasion, its increased activation is associated with cancer development as well. To get deeper insight into the behavior of Dishevelled proteins in cancer, we studied their expression in serous ovarian carcinomas [both low- (LGSC) and high-grade (HGSC)], and HGSC cell lines OVCAR5, OVCAR8 and OVSAHO. DVL protein expression in serous ovarian carcinomas tissues was analyzed using immunohistochemistry while DVL protein and mRNA expressions in HGSC cell lines were analyzed using western blot and quantitative real-time PCR. DVL1 protein expression was significantly higher in LGSC compared with normal ovarian tissue, while DVL3 was overexpressed in both LGSC and HGSC. DVL2 and DVL3 protein expression was higher in HGSC cell lines when compared with normal control cell line ...

NAD(P)H:quinone oxidoreductase (NQO1) is a flavoprotein that catalyzes two-electron reduction and detoxification of quinones and its derivatives. NQO1 catalyzes reactions that have a protective effect against redox cycling, oxidative stress and neoplasia. High expression of NQO1 is associated with many solid tumors including those affecting the colon, breast and pancreas; however, its role in the progression of ovarian carcinoma is largely undefined. This study aimed to investigate the clinicopathological significance of high NQO1 expression in serous ovarian carcinoma. NQO1 protein expression was assessed using immunohistochemical (IHC) staining in 160 patients with serous ovarian carcinoma, 62 patients with ovarian borderline tumors and 53 patients with benign ovarian tumors. Quantitative real-time polymerase chain reaction (qRT-PCR) was performed to detect NQO1 mRNA expression levels. The correlation between high NQO1 expression and clinicopathological features of ovarian carcinoma was evaluated by
High-grade serous ovarian cancer (HGSOC) is the most aggressive histological type of epithelial ovarian cancer, which is characterized by a high frequency of somatic TP53 mutations. We performed exome analyses of tumors and matched normal tissues of 34 Japanese patients with HGSOC and observed a substantial number of patients without TP53 mutation (24%, 8/34). Combined with the results of copy number variation analyses, we subdivided the 34 patients with HGSOC into subtypes designated ST1 and ST2. ST1 showed intact p53 pathway and was characterized by fewer somatic mutations and copy number alterations. In contrast, the p53 pathway was impaired in ST2, which is characterized by abundant somatic mutations and copy number alterations. Gene expression profiles combined with analyses using the Gene Ontology resource indicate the involvement of specific biological processes (mitosis and DNA helicase) that are relevant to genomic stability and cancer etiology. In particular we demonstrate the presence of a
High-grade serous ovarian cancer (HGSOC) likely originates from the fallopian tube (FT) epithelium, but advanced stages are mostly found outside the FT. We used ex-vivo cultures of HGSOC and knock-out of tumor suppressors in FT organoids to study changes in epithelial cells and niche requirements for normal and transformed FT cells. We found that transformed cells require BMP signaling and are growth arrested in Wnt rich medium. A SureSelectXT Automation Custom Capture Library (Agilent) target enrichment panel was designed. The enrichment panel comprised all coding exons of 121 genes associated with ovarian cancer. Capture was performed according to the manufacturers instructions using an NGS Workstation Option B (Agilent) for automat... (Read more) ...
The effective treatment of ovarian serous carcinoma remains a major challenge because of the recurrence of platinum-resistant tumors. The mechanism of platinum-resistance may involve decreased cellular uptake caused by abnormalities of transporters, intracellular cisplatin inactivation (e.g., caused by glutathione), and increased DNA repair (18). However, no available therapy prevents platinum-resistance.. TBX2 is overexpressed by numerous human cancers (7-14). TBX2 may serve as a prognostic factor of breast cancer (7,9), melanoma (8), gastric cancer (10), prostate cancer (11), laryngeal squamous cell carcinoma (12), and non-small cell lung cancer (14). TBX2 is associated with resistance to therapeutic drugs such as cisplatin and doxorubicin (15,16), and TBX2 therefore may serve as a therapeutic target.. One report shows that chromosome 17q12-q24 harbors strong candidates for ovarian tumorigenesis, such as LASP1 (17q12), TGF11 (17q21.32), MUL (17q23.2), TBX2 (17q23.2), AXIN2 (17q24.3), and GRB2 ...

High-grade serous ovarian carcinoma (HGSOC) is a lethal disease for which improved screening and treatment strategies are urgently required. Progress in these areas has been impeded by our poor understanding of HGSOC pathogenesis. The vast majority of ovarian cancer research is been based on the hypothesis that HGSOC develops from ovarian surface epithelial cells. However, recent studies suggest that , 50% of high-grade serous carcinomas involving the ovary likely arose from secretory cells of the fallopian tube epithelium. Consequently, current ovarian-based experimental models of HGSOC are inadequate in representing the full spectrum of the disease. The aim of our study was to develop the first experimental model of fallopian tube secretory epithelial cell (FTSEC) transformation and to use this model to answer three basic questions: 1) Can FTSECs be transformed in vitro?, 2) What genetic alterations are capable of transforming FTSECs?, and 3) Do transformed FTSECs give rise to high-grade ...
Ovarian cancer accounts for 5% of all female cancer-related deaths, more than any other reproductive cancer. Of the various histological subtypes, high-grade serous carcinoma is the most common. Mutations in BRCA1/BRCA2, which are associated with familial predisposition, are present in 10% of cases, while TCGA data demonstrates that P53 is mutated in 96% of high-grade serous ovarian carcinomas. In addition to aberrant P53 expression, severe aneuploidy with a near polyploid number of chromosomes is the only other genetic abnormality associated with these tumors. Ploidy changes occur early in tumor development, suggesting that they play a crucial role in oncogenic transformation. Furthermore, severe aneuploidy is associated with poor clinical outcome in patients, presumably due to its role in treatment resistance.. We used an in vitro cell culture model derived from ovarian cystadenomas, the benign counterparts of ovarian carcinomas, to investigate the molecular events leading to such ploidy ...
Objective: The purpose of this study was to investigate the prognostic value of lymph node ratio (LNR) in patients with stage III ovarian high-grade serous carcinoma (HGSC). Methods: A multicenter, retrospective department database review was performed to identify patients with ovarian HGSC at 6 gynecologic oncology centers in Turkey. A total of 229 node-positive women with stage III ovarian HGSC who had undergone maximal or optimal cytoreductive surgery plus systematic lymphadenectomy followed by paclitaxel plus carboplatin combination chemotherapy were included. LNR, defined as the percentage of positive lymph nodes (LNs) to total nodes recovered, was stratified into 3 groups: LNR1 (,10%), LNR2 (10%,= LNR,50%), and LNR3 (,= 50%). Kaplan-Meier method was used to generate survival data. Factors predictive of outcome were analyzed using Cox proportional hazards models. Results: Thirty-one women (13.6%) were classified as stage IIIA1, 15 (6.6%) as stage IIIB, and 183 (79.9%) as stage IIIC. The ...
This review focuses on recent advances in the area of low-grade ovarian serous neoplasia with emphasis on key diagnostic criteria, differential diagnosis, and disease classification based on current understanding of low-grade serous carcinogenesis. Despite considerable controversy surrounding serous tumors of low malignant potential (S-LMP) or borderline tumors, there have been great strides in our understanding of the serous group of borderline and malignant pelvic epithelial neoplasms in the past decade. Most S-LMP have a favorable prognosis, but recurrences and progression to carcinoma occur, sometimes following a protracted clinical course. Pathologic risk factors vary, but the extraovarian implant status is the most important predictor for progressive disease. Progression of S-LMP usually takes the form of low-grade serous carcinoma, although transformation to high-grade carcinoma is occasionally seen. A pelvic S-LMP - low-grade serous carcinoma pathway has been proposed based on global gene

Complex focal chromosomal rearrangements in cancer genomes, also called "firestorms", can be scored from DNA copy number data. The complex arm-wise aberration index (CAAI) is a score that captures DNA copy number alterations that appear as focal complex events in tumors, and has potential prognostic value in breast cancer. This study aimed to validate this DNA-based prognostic index in breast cancer and test for the first time its potential prognostic value in ovarian cancer. Copy number alteration (CNA) data from 1950 breast carcinomas (METABRIC cohort) and 508 high-grade serous ovarian carcinomas (TCGA dataset) were analyzed. Cases were classified as CAAI positive if at least one complex focal event was scored. Complex alterations were frequently localized on chromosome 8p (n = 159), 17q (n = 176) and 11q (n = 251). CAAI events on 11q were most frequent in estrogen receptor positive (ER+) cases and on 17q in estrogen receptor negative (ER-) cases. We found only a modest correlation between ...

Purpose: In high-grade serous ovarian cancer (HGSOC), higher densities of both B cells and the CD8+ T cell infiltrate were associated with a better prognosis. However, the precise role of B cells in the anti-tumor response remains unknown. As peritoneal metastases are often responsible for relapse, our aim was to characterize the role of B cells in the anti-tumor immune response in HGSOC metastases. Experimental Design: Unmatched pre and post-chemotherapy HGSOC metastases were studied. B-cell localization was assessed by immunostaining. Their cytokines and chemokines were measured by multiplex assay and their phenotype was assessed by flow cytometry. Further in vitro and in vivo assays highlighted the role of B cells and plasma cell IgGs in the development of cytotoxic responses and dendritic cell activation. Results: B cells mainly infiltrated lymphoid structures in the stroma of HGSOC metastases. There was a strong B-cell memory response directed at a restricted repertoire of antigens and ...

Uterine papillary serous carcinoma (UPSC) is an uncommon, but aggressive variant of endometrial carcinoma that has a high recurrence rate and poor response to therapy. It has a propensity to metastasize throughout the abdomen, similar to serous carcinoma of the ovary. In fact, many patients with disease apparently confined to the uterus have microscopic intra-abdominal spread at the time of diagnosis. Recurrences are common both in the pelvis as well as in the upper abdomen.. After staging and debulking of gross disease, adjuvant radiation therapy is recommended to treat patients with endometrial carcinoma at high risk for recurrent disease. High-risk features include histologic cell type, grade, depth of myometrial invasion, cervical extension, lymph-vascular invasion, adnexal involvement, intraperitoneal spread, positive peritoneal cytology, and positive lymph nodes. Pelvic radiation can limit local recurrences to less than 6.5%. However, approximately 25-30% of patients with high-risk ...

We assessed the impact of tubal ligation (TL) on the metastatic profile and survival of USC patients. Methods: Patient risk factors, process-of-care variables, and disease-specific parameters were annotated. Categorical variables were compared using the χ2 test. Overall survival (OS) was estimated via the Kaplan-Meier method. Results: Among 211 USC patients, fallopian tube status was documented in 142 patients; 35 had a history of TL ...
Objectives: To determine recurrence patterns and survival outcomes of stage II uterine papillary serous carcinoma (UPSC) patients treated by various modalities with an emphasis on carboplatin/paclitaxel-based chemotherapy (CT) +/- radiotherapy (RT). Methods: A retrospective, multi-institution study of women with stage II UPSC diagnosed from 1992 to 2006 was performed. All patients underwent comprehensive surgical staging. Treatment included observation (OBS), RT (vaginal brachytherapy, whole pelvic and/or whole abdominal therapy), or ≥ 3 cycles carboplatin/paclitaxel alone or with RT. Recurrence and survival outcomes were determined. Results: We identified 55 subjects: 10 treated with OBS, 26 with RT alone and 19 with CT +/- RT. After a median follow-up of 33 mos (range, 10-119), 20 recurrences (36%) were observed. There was an overall difference in recurrence based upon treatment (p = .013). Specifically, all CT +/- RT treated patients had a lower risk of recurrence (11%) compared to patients ...
Xu, J., et al. Mass spectrometry-based peptidome profiling of human serous ovarian cancer tissues. The International Journal of Biochemistry & Cell Biology. S1357-2725(18)30258-9. 10/12/2018.. We identified 634 differentially expressed peptides, 508 of these peptides were highly abundant in serous ovarian cancer tissues, a result consistent with higher protease activity in ovarian cancer patients. The difference in preferred cleavage sites between the serous ovarian cancer tissues and normal ovarian epithelium indicates the characteristic peptidome of ovarian cancer and the nature of cancer-associated protease activity. Interestingly, KEGG pathway analysis of the peptide precursors indicated that the differentially regulated pathways in ovarian cancer are highly consistent with the pathways discovered in other cancers. Besides, we found that a proportion of the differentially expressed peptides are similar to the known immune-regulatory peptides and anti-bacterial peptides. Then we further ...

Researchers used Caris Molecular Intelligence® to evaluate 240 uterine papillary serous carcinoma (UPSC) and 1,587 epithelial ovarian serous carcinoma (EOC-S) samples, and to compare the molecular profiles of the two cancer subtypes.. The tumor suppressor gene TP53 was the most commonly mutated gene in both UPSC and EOC-S (76% vs. 69%) samples. UPSCs were more likely than EOC-S samples to harbor mutations in the oncogenes PIK3CA (29% vs. 2%), FBXW7 (12% vs. 1%), KRAS (9% vs. 5%), the tumor suppressor protein PTEN (7% vs. 1%), and CTNNB1 (2% vs. 0%).. "Whereas uterine papillary serous carcinoma appears to have a distinct mutation profile, indicating higher activity of the PI3K/PTEN/mTOR pathway, we saw no differences between uterine papillary and ovarian serous carcinomas in alteration of the homologous recombination pathway," remarked principal investigator Robert DeBernardo, MD, Gynecologic Oncologist and Director of Minimally Invasive Surgery at the Cleveland Clinic Ob/Gyn & Womens Health ...
In this study a new low-grade serous ovarian carcinoma cell line, named as CAISMOV24, was characterized in terms of its in vitro cell growth, production of soluble biomarkers and expression of cell surface molecules. Additionally, CAISMOV24 was molecularly characterized and compared to its primary malignant cells for genomic alterations. In vitro models of well-characterized low-grade serous ovarian cell lines are currently limited in the literature. CAISMOV24 resulted from the in vitro spontaneous immortalization of primary malignant cells from ascites that was associated with a low-grade serous ovarian carcinoma. Although malignant cells of ovarian neoplasia from either tumor tissue or ascites can be cultivated in vitro for a limited period, only a minority of the primary cell cultures may become cell lines [14]. Spontaneous immortalization of primary cultures of malignant cells is an event occurring at a very low frequency. As an example, ODonnell et al. [11] reported the occurrence of only ...

N2 - "Invasive micropapillary serous carcinoma" has been proposed as a synonym for low-grade serous carcinoma by some expert pathologists. In contrast, Singer and colleagues reported that some serous carcinomas with conspicuous invasive micropapillary pattern (SC-IMPs) can show high-grade nuclear atypia. However, the molecular features of such tumors have not been well documented. The aim of this study was to demonstrate and emphasize the fact that high-grade serous carcinoma confirmed by immunohistochemistry and molecular analysis can show conspicuous invasive micropapillary pattern. We selected 24 "SC-IMPs" and investigated: (1) their morphologic features; (2) the immunostaining pattern of p53 protein; and (3) KRAS/BRAF/TP53 gene ...

Epithelial ovarian cancer is a leading cause of death in gynecological cancers. While several systematic studies have revealed the mutation landscape of serous epithelial ovarian cancer, other non-serous subtypes of the disease have not been explored as extensively. Here we conduct exome sequencing of nine non-serous epithelial ovarian tumors (six endometrioid and three mucinous) and their corresponding normal DNA as well as a tumor-only granulosa cell sample. We integrated the exome data with targeted gene sequencing for 1,321 genes selected for their involvement in cancer from additional 28 non-serous ovarian tumors and compared our results to TCGA ovarian serous cystadenocarcinoma and uterine corpus endometrial carcinomas ...
I guess my hamster days steroid high is over, because I slept 10 hours last night and woke up with something similar to what Marge described, a sort of fogginess. Its not bad, but I feel like if I crawled back under the covers, I just might go back to sleep again. (Not doing that!) I agree that we are all doing so much better than any of us probably dared to hope. There are surely some rough days ahead, but one day at a time is the way to go, and making the most of each good day. I wonder if we will continue to come here after our treatments are over??? I see 20-year survivors posting here on other boards, wanting to be here as a resource to those that come after them with their same cancers.

Eleven patients gained one or more classes of this drug blend for recurrent ailment, 5 of whom experienced prior publicity while in the First setting ...
Mutations in BRCA1 or BRCA2 (BRCA) are common in patients with high-grade serous ovarian carcinomas, and, when the wild-type allele is lost, BRCA mutations can impair DNA-damage repair by homologous recombination, leading to deletion or duplication of chromosomal regions, which is termed genomic loss of heterozygosity (LOH). Homologous recombination-deficient tumors are sensitive to PARP inhibitors such as rucaparib, but although homologous recombination deficiencies can also occur in ovarian tumors without BRCA mutations, molecular predictors of rucaparib sensitivity in BRCA wild-type tumors have not been identified. Swisher, Lin, and colleagues hypothesized that genomic LOH might predict homologous recombination deficiency and rucaparib sensitivity and enrolled 206 patients in an open-label phase II trial of rucaparib in patients with relapsed, platinum-sensitive, high-grade ovarian carcinoma. In total, 192 patients could be classified into subgroups: 40 had BRCA mutations, 82 were BRCA ...

Cancer cell lines have been, and will continue to be, important tools in oncology research, but there are major limitations in the fidelity of existing cell lines as a model of human cancers. Therefore, the aim of our study was to generate and characterize patient-specific cell lines from solid tumors that more faithfully recapitulate the primary tumor genetic and morphologic characteristics.. We performed cell line derivation on a primary human breast adenocarcinoma (ER+/PR+/HER2-), a lung adenocarcinoma, a high-grade serous ovarian carcinoma, and an endometrioid ovarian carcinoma procured from a commercial tissue bank. Portions were snap-frozen for molecular analysis, and the remainder was minced and processed for cell culture. Cells were cultured and the resulting monolayer was stained by immunocytochemistry with a pan-keratin antibody for the presence of epithelial cells. Any contaminating fibroblasts were removed. We extracted DNA from the resulting breast and lung cancer cell lines at low, ...

The intention of the information provided in this web site is at present for educational and research purposes only. The biological and clinical significance of STIC and STIL is a work in progress and their impact to clinical management has still to be defined. The investigators involved in this study and all the web pages in ovariancancerprevention.org do not recommend the use of this pathological and immunostaining classification for clinical practice at the present time. Ovarian high-grade serous carcinoma (HGSC) is the most lethal gynecologic malignancy and is characterized by frequent TP53 mutations and a high level of chromosomal instability, which is reflected by widespread DNA copy number changes compared to other types of epithelial ovarian carcinomas. Unlike cancers arising in the colon, breast, cervix, endometrium, prostate, and pancreas, for ...

Patients with ovarian high-grade serous carcinoma (HGSC) initially respond to treatment with the chemotherapeutic agents carboplatin and paclitaxel, but frequently experience tumor relapse. However, the mechanisms underlying the development of resistance to these drugs remain poorly understood. Yu and colleagues found that the levels of spleen tyrosine kinase (SYK) and phosphorylated SYK were increased in recurrent ovarian tumors isolated from patients previously treated with carboplatin and paclitaxel compared with matched primary untreated tumors. In addition, SYK expression and activation were upregulated in paclitaxel-resistant ovarian cancer cell lines and positively correlated with paclitaxel response in vitro, suggesting that SYK overexpression may confer chemoresistance. SYK inactivation via knockdown or pharmacologic inhibition with the active metabolite of fostamatinib, R406, impaired the growth of ovarian cancer cells and synergistically enhanced the sensitivity of ...
