Filter by:An accurate preoperative diagnosis of an ovarian tumor is important for the patients' surgical work-up, proper referral to oncological centers and for the patients' mental wellbeing since uncertainty about the nature (benign vs malignant) of an ovarian tumor may cause anxiety. Currently, the Risk of Malignancy Index (RMI), with a cut-off value of 200, is often used in the Netherlands to select patients with an increased risk of ovarian cancer that should be referred to an oncologic center. However sensitivity and specificity of the RMI-score are far from optimal. Around 40% of the referred patients have benign disease in final pathological examination. Therefore, other models have been developed, such as the IOTA (International Ovarian Tumor Analysis) consortium algorithms, but these models require training, expertise and are subjective. To determine the nature of an ovarian tumor, histological examination is the golden standard. However, a pre-operative biopsy of an ovarian tumor is undesirable because of the risk of spill of tumor cells in the abdominal cavity. Therefore, there is an urgent need for non-invasive diagnostic tools to determine the nature of an ovarian tumor pre-operatively. Liquid biopsies could be such a non-invasive tool. Currently, circulating tumor DNA (ctDNA) circulating tumor cells (CTC), microRNA (miRNA) and tumor-educated platelets (TEPs) are available and can function as a potential blood-based biosource for (early) cancer diagnostics. Previous studies show promising results of liquid biopsies are used in (early) detection of cancer, also for ovarian cancer. Therefore, a diagnostic algorithm will be developed using ct-DNA and TEPs as liquid biomarkers in combination with the existing ultrasound models (RMI and IOTA-models) and tumor markers (CA125 and HE4) to differentiate between early ovarian cancer and benign ovarian tumors pre-operatively. Nature and extent of the burden and risks associated with participation, benefit and group relatedness. There is no extra burden/risk for the patients in this study. Five extra vials of blood will be collected from each participant and two questionnaires will be filled out.
This is a single arm phase 1b/2 evaluation of the combination of oregovomab, and bevacizumab, paclitaxel carboplatin in adult subjects with CA125-associated, advanced recurrent epithelial ovarian, fallopian tube or peritoneal carcinoma (FIGO Stage III/IV) with BRCA-wild type, previously treated with 1 prior lines of therapy, and with platinum free intervals of >6 months since last platinum-based treatment.
This is a Phase 1, open-label, multicenter, dose-escalation and expansion study evaluating the safety, tolerability, PK, pharmacodynamics, and clinical antitumor activity of XB002 administered IV q3w alone and in combination with nivolumab to subjects with advanced solid tumors.
This randomized, double-blind, 2-arm study will evaluate the efficacy and safety of Chiauranib plus weekly paclitaxel versus placebo plus weekly paclitaxel in patients with Platinum-refractory or Platinum-resistant Recurrent ovarian cancer.
This study is being done to answer the following question: What are the effects of a new drug or drugs on ovarian cancer? The pre-study screening may be done to test a sample of tissue for biomarkers to determine participation in the study.
Early stage high-grade cancer, endometrial and ovarian, has few, if any, symptoms or signs. When symptoms appear, the disease may be in advanced stage as the disease has left the gynaecological organs and metastasized to the pelvic/abdominal cavity. The McGill research group had showed in the DOvEE trial (NCT02296307), that fast-track assessment with transvaginal ultrasound scans (TVUS) and serial CA125 of women with vague symptoms associated with ovarian and endometrial cancer did diagnose these cancers earlier in the disease trajectory, with low-volume resectable disease, but only after the cancer had already become Stage III. One way to detect these cancers earlier is to screen asymptomatic women. Unfortunately, none of the currently available tests, including TVUS and CA-125 have been shown to be useful for screening for ovarian or endometrial cancer. The McGill team has developed a genomic assay to screen and detect these cancers earlier in the trajectory than is currently the case. The test identifies pathogenic somatic mutations (necessary early steps in the development of these cancers), in an uterine cytological sample. It is able to do so by incorporating a deep machine-learning derived classifier that can discriminate the mutational signature of these cancers from benign disease with a sensitivity of 70% and a specificity of 100% in a population with high background mutational burden. In addition to the intra-uterine cytological sample, the test includes an assay of a saliva sample to identify germline mutations that predispose to hereditary endometrial/ovarian cancers as well as breast and colon cancers. The test was developed in a retrospective population in whom the assay was done pre-operatively and the diagnosis of malignancy versus benign gynecological disease was confirmed by detailed pathological analysis of the uterus, tubes, and ovaries after surgical resection (NCT02288676). The test is now ready to be tested as a phase III diagnostic test in the general population to see if these results are just as promising in the community at large.
RECHALLENGE WITH PEGYLATED LIPOSOMAL DOXORUBICIN ADDED TO TRABECTEDIN IN RECURRENT OVARIAN CANCER: A MULTICENTER, PROSPECTIVE TRIAL
To test the effect of intravenous paclitaxel plus intraperitoneal cisplatin for neo-adjuvant chemotherapy in patients with advanced ovarian cancer, the investigators conducted a phase III single arm clinical trial. Included patients will receive interval debulking surgery after 2-6 cycles neoadjuvant chemotherapy based on the clinical judgment of the gynecologic oncologist. Six cycles of chemotherapy will conducted after surgery. And the neoadjuvant chemotherapy is as follows: paclitaxel 135 mg/m2 i.v. and cisplatin 75 mg/m2 i.p. on day 1. The primary end point is optimal debulking rates. the investigators also will evaluate effect on parameters of volume of ascites, tumor size, duration of surgery, hemorrhage, hospitalizations and postoperative complication etc. After comparing with data published online, the investigators will try to find out if paclitaxel i.v. plus cisplatin i.p. is a superior neoadjuvant chemotherapy for advanced ovarian carcinoma.
This is a Phase III, randomised, double-blind, placebo-controlled, multicentre, international study assessing the efficacy and safety of maintenance olaparib compared with placebo in BRCAwt participants with Stage III to IV high grade serous or endometroid ovarian cancer (including fallopian tube cancer or primary peritoneal cancer) who are in complete or partial response following treatment with standard first-line platinum-based chemotherapy.
The purpose of this study is to find out whether using the PINPOINT imaging system intra-operatively can reduce the risk of anastomotic leaks and other complications after surgery for ovarian cancer, compared with standard intra-operative assessments alone. The PINPOINT endoscopic fluorescence imaging system uses a special camera and a fluorescent (glowing) dye that can evaluate the blood flow of the bowel in real-time. If there is an area that appears concerning, the surgeon can correct the problem during the procedure.
