Evaluation of GTPase Inhibition by Post-operative Intravenous Ketorolac in Ovarian Cancer Patients...
Ovarian CancerFallopian Tube Cancer1 moreThere is a move towards personalized medicine in cancer care, and significant effort is underway to evaluate new targeted therapeutics for the treatment of ovarian cancer. One way to identify potential new drug targets is by screening a drug library to determine whether drugs in the library target key kinase or enzymatic sites in cellular signaling pathways. Previous preclinical work and pilot studies demonstrated that ketorolac (a type of non-steroidal anti-inflammatory drug) inhibits GTPase activity in ovarian cancer cells retrieved from the post-operative peritoneal cavity. The purpose of this study is to confirm that this inhibitory effect is ketorolac driven and not a specific effect of the post-operative peritoneal compartment.

Magtrial: Magtrace® as Tracer for Sentinel Lymph Node Detection in Early Stage Epithelial Ovarian...
Ovarian CancerLymph Node MetastasisEpithelial ovarian cancer (EOC) remains the tumour with the most unfavourable prognosis within the field of gynaecological oncology. The incidence of ovarian cancer in the Netherlands in 2008 was 14.5 per 100.000, with 12.3 deaths per 100.000. In the US in 2007 the incidence was 13.0 per 100.000 and there were 8.2 deaths per 100.000. The high mortality rate is partially due to the fact that approximately 75% of patients is diagnosed with advanced stage EOC. The remaining 25% of patients are diagnosed in an early stage, which require a complete surgical staging procedure including pelvic and para-aortic lymphadenectomy. Although this lymphadenectomy is standard-of-care, it leads to significant morbidity in these patients. Mainly direct postoperative complications such as infection, repeat surgery and early death have been reported. Also, long-term complications such as lymph cysts or lymphedema have been described. A potential method to reduce this morbidity and mortality, as already been described in other cancers such as breast cancer and vulvar cancer, is utilizing a sentinel lymph node (SLN) technique. By identifying and resecting the SLN, the patient is potentially spared form lymphadenectomy.
Metformin and Chemotherapy in Treating Patients With Stage III-IV Ovarian, Fallopian Tube, or Primary...
Brenner TumorMalignant Ascites26 moreThis randomized phase II trial studies how well metformin hydrochloride and combination chemotherapy works in treating patients with stage III-IV ovarian, fallopian tube, or primary peritoneal cancer. Drugs used in chemotherapy, such as carboplatin, paclitaxel and docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Metformin hydrochloride may help carboplatin, paclitaxel and docetaxel work better by making tumor cells more sensitive to the drugs. Studying samples of blood and tissue in the laboratory from patients receiving metformin hydrochloride may help doctors learn more about the effects of metformin hydrochloride on cells. It may also help doctors understand how well patients respond to treatment. Giving metformin hydrochloride together with combination chemotherapy may kill more tumor cells.
[68Ga]Ga-FAPI-46 PET/CT in Ovarian Cancer
Ovarian CancerFifty (n=50) patients with newly diagnosed ovarian cancer will undergo FAPI PET/CTs in addition to routine diagnostic workup (including FDG PET/CT) at primary staging and restaging. The FAPI PET/CT results will be compared to conventional imaging (including FDG PET/CT) using histopathology as reference standard, and the diagnostic accuracy will be determined. FAP-immunohistochemistry will be conducted in surgical specimens. FAPI PET/CT's impact on patient management and the prognostic value of FAPI PET/CT will be evaluated.
SEQUENTIAL PROFILING OF TUMOR-DERIVED CIRCULATING CELL-FREE DNA (ctDNA) IN ADVANCED OVARIAN CANCER...
Ovarian CancerOvarian cancer (OC) is the third most common gynaecologic cancer worldwide and has the highest mortality rate among gynaecologic cancers. Despite the advances in cytoreductive surgery and frontline chemotherapy, recurrence is a common event in the advanced disease setting, with more than 70% of women experiencing relapse within two years from diagnosis. New strategies to anticipate the diagnosis of recurrence have been investigated in the last years. In this context, standard serum biomarkers, such as CA-125, and radiological evaluation are commonly used for disease surveillance, However, the early identification of relapsed disease as well as the identification of patients at higher risk for recurrence are still unmetclinical needs. Novel and reliable molecular biomarkers, which might also better represent the intrinsic molecular complexity of OC, could help clinicians to address this important challenge. Circulating tumor DNA (ctDNA) analysis has recently emerged as a non-invasive tool to profile and monitor tumor evolution over time. CtDNA has been extensively studied in several neoplasms in order to evaluate its ability in anticipating detection of relapse compared to common markers used in clinical practice. Wehave designed a study to assess the ability of ctDNA to detect recurrence and progression of disease and to provide a genomic characterization, during follow-up of patients with advanced OC. If proven effective and reliable, ctDNA could be introduced into routine surveillance programme for OC.
Health-Economic Evaluation of Early Diagnosis of Epithalial Ovarian Cancer Recurrence Using the...
Epithelial Ovarian CancerIn this study, we hypothesize that calculating the ROMA score (CA125 + HE4 blood marker assay) will enable faster, more targeted diagnosis and management of epithelial ovarian cancer recurrence than the CA125 marker assay alone. This early identification of recurrence would then improve patients' quality of life, since it would increase the chances of benefiting from less invasive and less morbid surgery. It would also reduce the cost of patient management following disease progression. If our hypothesis is confirmed, the results of this study will enable us to update the recommendations for post-treatment follow-up of patients in remission from epithelial ovarian cancer, as well as reimbursing the HE4 marker assay (and thus the calculation of the ROMA score).
