Active clinical trials for "Carcinoma, Ovarian Epithelial"

The majority of primary cancers of the ovary or peritoneum are represented by high-grade serous adenocarcinomas. These are rare pathologies, the incidence of which is estimated at 7.1 per 100,000, representing approximately 4,500 new cases per year in France (INCA 2017). In the absence of effective screening, nearly 85% of patients have an advanced disease at diagnosis (corresponding to the FIGO III or IVA stage, characterized by diffuse peritoneal involvement). Despite multidisciplinary care, the majority of patients (80%) will recur within a median of 18 to 24 months. It is therefore necessary to develop new tools, in particular molecular, in order to allow : to better select patients accessible to full interval surgery to exclude patients who would not benefit from this surgery in terms of survival In 2010, Chibon et al. identified, from a cohort of patients with soft tissue sarcoma (STM), a molecular signature (called CINSARC), based on the expression profile of 67 genes involved in mitotic control and chromosomal integrity. The team showed that this transcriptomic signature is an independent prognostic factor in different types of STM, but also a prognostic factor more discriminating than the histological grade (FNCLCC), historical and major prognostic factor of STM. Being initially made from frozen material and on a DNA biochip (Affymetrix), this signature was unusable outside the field of fundamental research. This is why CINSARC has been gradually optimized, first by the RNA sequencing technique on frozen tissue fixed in formalin (FFPE), and recently on FFPE tissue by the NanoString® technique. This very sensitive and inexpensive technique requires only small amounts of total RNA, making it compatible with use on "routine" diagnostic samples, microbiopsy or surgical biopsy, opening the door to real clinical application. Several clinical studies using this latest CINSARC optimization (called NanoCind®) to determine the treatment of patients with STM will also begin soon. As a result of this work, necessary in order to more precisely support the potential of CINSARC in this pathology, the investigators hope to be able to assess from the diagnosis the evolutionary potential of the patients, which could make it possible to evaluate therapeutic strategies adapted to the profiles of each subpopulation: the investigators can for example imagine in theory a therapeutic de-escalation for low-risk patients, or else, for very high-risk patients, an intensified strategy.

Observational, clinical study. Intention to include 40 patients (20 patients treated with trabectedin and 20 with cisplatin hypersensitivity) The investigators investigate the role of trabectedin in combination with PLD and cisplatin in treating platinum sensitive ROC being allergic to carboplatin. The investigators focus on adverse events and evaluate if these are tolerable for the patients and further evaluate the measurable treatment effect on the tumor burden.

To compare dose-dense chemotherapy with intraperitoneal chemotherapy in patients with advanced stage ovarian cancer.

The French cooperative group GINECO proposes to implement an observational study to describe a real situation, in daily practice tolerance and methods of administration of bevacizumab (Avastin ®)

The purpose of this study is to find out if complementary and alternative medicines (CAM) should be included with traditional therapy for women with ovarian cancer. Some of the alternative medicines include non-traditional drug and herbal therapies along with dietary and nutritional strategies. Only a few of these alternative medicines have been tested with women with ovarian cancer.

This is an observational and sample collection study involving patients (alive or deceased) from several clinical trials who had received the investigational drug, olaparib in other research studies. There is no intervention given for this study. This research is being done to understand of the mechanisms involved in patients whose cancer responds well and whose cancer does not respond well to investigational drug, olaparib, to help better understand how olaparib works and to better identify patients who may benefit from this therapy.

Tumor response to NAC predicts survival and can be considered a surrogate prognostic marker. Three tiered chemotherapy response score (CRS) of omental tissue sections showed a significant association with survival. In patients with CRS 1 or 2, NAC selects a subpopulation of chemotherapy resistant tumor cells. This study will examine comprehensive molecular analyses on the residual disease of 104 clinically defined high-grade serous carcinoma after NAC, including next-generation sequencing on 14 matched pretreatment biopsies. This information together with immune marker expression and BRCA expression, will provide a unique opportunity to guide biomarker-driven adjuvant studies targeting these chemotherapy-resistant tumor cells.

Green tea is extracted from steam treated leaves, allowing the preservation of catechins, the active elements of the infusion. Catechins are recognized for their anti-cancer activity. Catechins act on the capacity of cancer to disseminate to other organs because of their anti-protease action. Proteases are proteins capable of digesting the cancer environment and facilitating the progression of cancer cells to blood vessels which will bring them to distant organs. We know that ovarian cancer responds well to the initial treatment of chemotherapy but tends to recur rapidly. We intend to provide green tea with higher concentrations of catechins to women with complete remission of their ovarian cancer in an attempt to delay cancer relapse. We also intend to identify, with molecular technologies, the proteases involved in ovarian cancer recurrence and response to catechins. Our objective is to test the hypothesis that green tea intake may delay ovarian cancer recurrence and to develop tools to predict which women will best benefit of the addition of green tea to their initial treatment.

RATIONALE: New diagnostic procedures, such as glycan analysis, may be effective in finding ovarian epithelial cancer. PURPOSE: This clinical trial is studying how well glycan analysis works in diagnosing cancer in women with ovarian epithelial cancer and in healthy female participants.

The goal of this study is to determine the apoptosis-inducing efficacy of TRA-8 in patient ovarian cancer tissues using a tissue slice technology. In addition, we want to evaluate the expression of apoptosis regulatory proteins using multiplex proteomic technology and its correlation with TRA-8-induced cytotoxicity in patient ovarian cancer tissues.
