Active clinical trials for "Carcinoma, Ovarian Epithelial"

RATIONALE: Studying samples of blood and tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how well patients will respond to treatment. PURPOSE: This research study is looking at biomarkers in predicting response in patients with advanced ovarian epithelial cancer, fallopian tube cancer, or primary peritoneal cancer.

The purpose of the study is to understand why there are differences between individuals in the way they respond to paclitaxel chemotherapy.

In this prospective, observational study the investigators assess the perioperative course of right ventricular function in combination with the venous return in patients undergoing major non-cardiac surgery. The study aims to investigate if patients undergoing major non-cardiac surgery develop an impairment of right ventricular function and/or venous return. Furthermore, the study evaluates if an impairment of right ventricular function and/or venous return is associated to left ventricular function, arterial side of the circulation and to postoperative clinical outcome.

The purpose of this study is to determine whether a relationship exists between a previously established diagnosis of endometriosis and the consecutive risk of developing a clear cell or endometrioid ovarian carcinoma. All histopathological records since 1980 with these diagnoses (endometriosis, clear cell and endometrioid ovarian carcinoma) will be reviewed. Cancer registry data will be assessed to investigate differences in survival of women with endometriosis-associated ovarian carcinomas and those ovarian carcinoma patients without previous diagnosis of endometriosis.

This research trial studies tissue samples from patients with ovarian cancer in the laboratory. Analyzing tissue samples from patients in the laboratory may help doctors learn more about cancer.

Patients with a diagnosis listed under "conditions" below are eligible to be considered for the EAP. These conditions must be serious or life-threatening at the time of enrollment and appropriate, comparable, or satisfactory alternative treatments must have been tried without clinical success. Patients with conditions not listed under "conditions" below are not eligible for the tazemetostat EAP.

Epithelial ovarian carcinomatous and borderline components sometimes appeared in one patient. This study aims to analyze the genomic patterns of the carcinomatous and borderline components in the ovarian epithelial tissues. These tissues will be collected from paraffin section by microdissection to distinguish normal, carcinomatous and borderline tissues.

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.

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.
