4FMFES-PET Imaging of Endometrial and Ovarian Cancers
Endometrial CancerOvarian CancerThis project is about exploring a novel method to detect ovarian and uterine cancers earlier and better. More precisely, a high-performance radioactive estrogen analog will be used to visualize hormone-sensitive uterine and ovarian tumors using PET imaging. Not only this imaging methodology could improve the whole-body assessment of those diseases, but will also hint clinicians about the optimal course of therapy to undertake. The lead investigator's team designed in the past years an innovative radioactive estrogen derivative tracer (4FMFES) for the medical imaging modality termed Positron Emission Tomography (PET). The compound was first shown to be safe for human use. Recently, a clinical trial demonstrated that 4FMFES-PET is superior to any existing comparable tracer for detection of hormone-sensitive breast cancer patients. 4FMFES is particularly useful to pinpoint unsuspected metastases early, which allowed better breast cancer patient management and staging. 4FMFES and standard FDG PET imaging were shown to be complementary in breast cancer, the use of both techniques together providing a detection rate nearing 100%. Since ovarian and uterine cancers are about as likely to be targeted by 4FMFES as breast cancer, the use of this novel precision imaging method will be adapted to those other indications. In general, the sooner a cancer is diagnosed and treated, the better the outcome of a patient will be. Gynecological cancers lack precise screening and detection tools. In particular, while a majority of uterine cancers are relatively well managed, patients burdened with metastatic burden have a much worse prognosis, and precise and early detection of those lesions will greatly help clinicians to better treat those complicated cases. As for ovarian cancers, they are usually devoid of clinical symptoms until late onset, which partly explain the high mortality rate of this disease. Hence, for both diseases, a precision, whole-body imaging technique will allow earlier assessment, followed by earlier intervention, resulting in improved survival rate and better quality of life for patients.
Investigation of Tumour Spectrum of Germline Mutations in Breast and Ovarian Cancer Genes.
Hereditary Breast and Ovarian CancerMutationTUMOSPEC is a national family study designed to measure the relative and absolute risk of cancer for carriers of deleterious mutations to these "new" breast cancer (BC) susceptibility genes. Index cases will be enrolled consecutively from patients attending an appointment at one of the Unicancer centres, with no other inclusion criteria, and offered a BRCA1/2 analysis as part of their care plan. A panel of 24 TUMOSPEC genes, chosen in advance by a steering committee, will be tested as the same time as the BRCA1/2 genes, at one of the usual BRCA1/2 analysis laboratories belonging to the same network and participating in the study. If a mutation is found, the index cases will be asked to invite their first and second degree family members and their cousins to take part in the study, regardless of whether they have cancer. Saliva samples will be then taken and used for a targeted analysis of the familial abnormality. Each participant will also complete an epidemiological questionnaire in order to gather information about his/her medical history and any exposure to various risk factors. All medical and genotype data will be centralised at the Genetic Epidemiology Research Platform (PIGE, INSERM). The cumulative mutation frequency for all genes is estimated at 10%. Penetrance will be analysed using methods designed to minimise selection bias. The expression spectrum of the mutations will also be described. For genes where the number of mutated families is too low, the data may be contributed to international consortia. The main project will be preceded by a two-year feasibility study, using the same inclusion criteria and logistic circuits. It is this pilot study to which the current funding application relates.
Use of the CA 125 Algorithm for the Early Detection of Ovarian Cancer in Low Risk Women
Ovarian CancerThe goal of this clinical research study is to evaluate a method involving a blood test, called CA-125, that may be helpful in the early detection of ovarian cancer in women who are at low risk.

PET Imaging of Solid Tumors by a Novel Tracer, 68Ga-FAPI
Pancreatic NeoplasmsStomach Neoplasms2 moreCancers of the pancreas, bile ducts, stomach and ovaries are dismal diseases with most patients being diagnosed in advanced stages leading to a bad prognosis. These cancers can be difficult to diagnose and sometimes impossible to differentiate from underlying benign conditions. Establishing the correct diagnosis of primary cancer lesions and possible spread to other organs in time is pivotal for choosing the right therapy. Routinely applied staging procedures are however not always reliable. The main aim in this study is to evaluate the diagnostic accuracy of PET/CT with a novel radiotracer, FAPI, in the primary diagnosis of cancers in the pancreas, stomach and bile ducts as well as in patients with primary and recurrent epithelial ovarian cancer (EOC).
Mapping Sentinel Lymph Node in Initial Stages of Ovarian Cancer
Ovarian CancerSentinel Lymph NodeEpithelial ovarian cancer (EOC) diagnosed in the initial stage (stage I-II) require complete staging surgery to histologically assess the possible existence of peritoneal or lymph node disease. Systematic pelvic and paraaortic lymphadenectomy in stage I-II EOC is essential since confirming the presence of lymph node metastases means re-staging the disease as stage III. This change of stage has important prognostic and therapeutic implications. However, the lymph node involvement rate is around 10-30% (average of 15%). Systematic pelvic and para-aortic lymphadenectomy carries a risk of intraoperative complications, as well as longer operative time, postoperative complications and longer hospital stay. Moreover, by now there is no evidence suggesting a possible therapeutic value. The sentinel lymph node (SLN) detects the first level of lymph node drainage. The absence of metastases in the SLN predicts the absence of tumor infiltration of the rest of lymph nodes of the same anatomical region and allows to safely avoid lymphadenectomy and its associated morbidity. In addition, the exhaustive evaluation of the SLN by ultrastaging and immunohistochemical study allows to increase the detection of microscopic disease. Sentinel lymph node (SLN) biopsy, implemented in clinical practice in other gynecological tumors (breast, vulva, cervix or endometrium), has been studied very little in the initial ovarian epithelial cancer. Unlike other gynecological tumors, there are multiple anatomical and technical aspects that largely explain this lack of information. The double ovarian vascularization that accompanies lymphatic drainage explains this higher complexity. Therefore, at the present time, the detection of SLN in the initial EOC remains an experimental area without applicability in clinical practice. There are multiple doubts and issues to be resolved regarding the different tracers, the site and time injection and the actual accuracy of the SLN versus the lymphadenectomy.

Adult Patients With Platinum-sensitiveRelapsed1 moreOvarian cancer is the seventh most common cancer in women worldwide and is the leading cause of gynecologic cancer deaths in high-income countries. Standard treatment for newly diagnosed advanced ovarian cancer consist of cytoreductive surgery and platinum-based chemotherapy with or without concurrent and maintenance bevacizumab, a vascular endothelial growth factor (VEGF) inhibitor. A majority of women with epithelial ovarian cancer respond well to first-line platinum-based chemotherapy. There is however a high rate of relapse/recurrence (disease progression ranging from 10 to 26 months). Poly ADP ribose polymerase inhibitors (PARPi), a new class of therapeutic molecules have recently revolutionized this paradigm, demonstrating progression-free survival (PFS) advantages in several trials. The PARPi molecule Niraparib has obtained its market authorization after the NOVA trial as second maintenance treatment line, irrespectively of patients' BRCA-mutated gene or HR status. Since, results of the Phase III trial PRIMA, have demonstrated that Niraparib can also provided a significant PFS increase as first line maintenance treatment, for adult patients with platinum-sensitive, relapsed, high grade serous epithelial ovarian cancer who are in response (complete response or partial response) to platinum-based chemotherapy, irrespectively of their BRCA-mutated gene or HR status. However, despite its high therapeutic potential, Niraparib at standard dose (200 or 300mg/day) is known to lead to hematologic toxicity and/or nephrotoxicity. This was demonstrated during the NOVA trial (the dose of Niraparib having to be reduced in 80% of the patients to reduce toxicity). A retrospective study of the NOVA trial indicates that 2 predictive factors leading to hematologic toxicity were a weight <77kg and an initial platelet count <175 G/L. However, it seems more complex as 50% of patients with an initial weight between 58 and 77kg have not reported thrombocytopenia. Same for platelet count. Creatinine clearance below 60ml/min and an hypoalbuminemia <35 g/l have also been identified in another study as predictive factors to thrombocytopenia. The inter-individual heterogeneity in terms of toxicity regarding Niraparib is high and still not well understood. The aim of our study is therefore to better identify which clinical, biological and pharmacokinetic metrics can be considered as toxicity induction causes when Niraparib is used as maintenance treatment (200 or 300mg/day) for ovarian cancer patients.
Transvaginal Ultrasonography as a Screening Method for Ovarian Cancer
Ovarian CancerThis is a large, prospective, single-arm cohort study of transvaginal ultrasonographic screening for ovarian cancer in intermediate to high-risk women from Kentucky. Detection of ovarian malignancy often occurs subsequent to the initial transvaginal sonography (TVS) screen; therefore, it is important to offer continued screening to study participants based on our published algorithm. Screening will be available to participants for as long as they elect to receive it. The primary study endpoints are to determine if prospective serial transvaginal ultrasonography can decrease the false-positive (FP) percentage and improve the positive predictive value (PPV) as suggested by retrospective analysis without compromising the detection of true positives or promote the occurrence of false negatives.
