Active clinical trials for "Ovarian Neoplasms"

The aim of the study is the assessment of tumour sites critical for the achievement of optimal cytoreduction in patients with advanced ovarian cancer using Ultrasound, CT and WB-DWI/MRI. The study uses an equivalence design with a hypothesis that cases with non-resectable disease identified by Index test (Ultrasound, CT and WB-DWI MRI) are equivalent to a portion of cases identified during surgery.

The homologous recombination deficiency (HRD) status in Chinese population with epithelial ovarian cancer (EOC) is little known. This study would recruit 1300 Chinese EOC patients. A multi-panel testing of 36 genes would be given for these patients in their peripheral blood and tumor tissues. These 36 genes include: BRCA1, BRCA2, ABRAXAS1(FAM175A）, ATM, ATR, BAP1, BARD1, BRIP1, C11ORF30（EMSY）, CDK12, CHEK1, CHEK2, FANCA, FANCC, FANCD2, FANCI, FANCL, MRE11A, NBN, PALB2, PPP2R2A, PTEN, RAD50, RAD51B, RAD51C, RAD51D, RAD54B, RAD54, MLH1, MSH2, MSH6, PMS2, EPCAM, STK11, TP53, CDH1. The study would select 150 patients with pathogenic or likely pathogenic mutations in BRCA1/2 and 150 patients without these mutations to further explore the HRD status. The HRD model is based on the loss of heterozygosity (LOH), telomere allele imbalance (TAI) and large-scale state transitions (LST). The mutated genes, HRD score model and their relationship with the prognosis, would provide a full description of for the Chinese EOC patients.

All participants will be subjected to Serum measurements of CA-125 by the immunoradiometric assay, Ultrasound evaluation of the Adnexal masses which is described according to origin (ovarian/extraovarian); position (right/left/bilateral); number of lesions; type of lesions (unilocular/multilocular); size in three dimensions (longitudinal, anteroposterior and transverse diameters); intracystic fluid echogenicity; number of loculations; presence and size of septations (only thickest one of septations is considered); presence, number and size of solid papillary projections (largest thickness is considered); presence and size of the largest solid component (three diameters); presence and measurement of fluid volume in the posterior cul-de-sac and presence and location of lesions suggestive of metastases. Then surgical intervention will be done with pathological examination of the specimen

The investigators want to compare the use of MRI with PET/CT preformed after 1 hour and 3 hours in preoperative assessment of resectability. The investigators' hypothesis is that dual time PET/CT performed at 60 and 180 minutes will increase the diagnostic accuracy of conventional PET (performed at 60 minutes) in preoperative assessment of resectability. Further more the investigators suggest that the GLUT/G6Pase index correlates to the SUVmax. And retention index (RI, see Methods - PET protocol) is a prognostic marker in ovarian cancer.

To develop a robust prediction model to predict the occurrence of grade 3-4 neutropenia induced by adjuvant paclitaxel/carboplatin chemotherapy in patients with epithelial ovarian cancer and to validate this model.

The purpose of this study is to create new tests to identify biomarkers for ovarian cancer so that a screening test can be developed. For patients who have a diagnosis of ovarian Cancer, researchers will use blood samples before and after treatment to see if disease status can be determined by measuring the amount of biomarker.

Purpose: To investigate the prevalence of the germline mutations in the BRCA 1/2 and mismatch repair genes in patients with epithelial ovarian cancer (EOC) and their relatives, and related somatic mutations in tumor tissues in the northern part of china. Patients and methods: A multicenter prospective study will be hold in the northern part of china form 2017. About 1000 female patients with epithelial ovarian cancer and their ralatives will be tested for germline mutations in the BRCA 1/2 and mismatch repair genes and related somatic mutations in tumor tissues, regardless of the family history. Study type: Observational Official title: Prevalence study of germline mutations in susceptibility ovarian cancer genes in patients with epithelial ovarian cancer and somatic mutations in their tumor tissures in the northern part of china. Enrollment: 1000

Collect blood samples and associated clinical data prior to, during, and post radiation treatment.

The purpose of this study is to determine if there are markers in plasma that can be used to develop a diagnostic panel for early detection and diagnosis of high grade serous epithelial ovarian cancer.

It is now felt that the majority of ovarian cancers originate in the fallopian tubes. Opportunistic salpingectomy has been found to decrease ovarian cancer risk by approximately 65%, with additional removal of the ovaries decreasing risk up to 98%. Using data collected under IRB #21841 and a population based statistics model we found that performing opportunistic salpingectomy during non-gynecologic abdominal surgery could decrease the incidence of ovarian cancer by 28-38%.
