Active clinical trials for "Carcinoma, Ovarian Epithelial"

Epithelial ovarian cancer (EOC) is a tumor entity featured by frequent involvement of peritoneum, also called peritoneal carcinomatosis. It is a type of metastasis accompanied by significant cancer-associated fibroblasts (CAFs) accumulation. Fibroblast activation protein (FAP) is a protein that is overexpressed on CAFs and can be non-invasively monitored by a novel radiotracer called 68Ga-FAPI-04 positron emission tomography/computed tomography (PET/CT). In this study, we will explore the value of 68Ga-FAPI-04 PET/CT in patients with epithelial ovarian cancer who are scheduled for surgical intervention. The findings of 68Ga-FAPI-04 PET/CT will also be compared with that of 18F-2-fluoro-2-deoxy-D-glucose fluorodeoxyglucose (18F-FDG) PET/CT, which is one of the most commonly used modalities in evaluating EOC, and histological findings.

This is a single-centre study based on the Simon 2-stage optimax design: 12 patients will be enrolled initially (Stage I), which will then be expanded to a further 13 patients (Stage II) if 3 or more patients enrolled in stage I of the study achieve an objective response with the chemotherapeutic agent selected by the drug screen assay. A total of 25 patients will be included in both stages of study. Patients enrolled on study will undergo a fresh biopsy of tumour lesion to obtain cells that will be used to generate patient-derived tumour organoids based on the Invitrocue technology. Organoids will then be subjected to a 10-drug panel screening including: 5-fluorouracil, carboplatin, cyclophosphamide, docetaxel, doxorubicin, gemcitabine, irinotecan, oxaliplatin, paclitaxel and vinorelbine. A further 5 drugs (etoposide, ifosfamide, methotrexate, pemetrexed and topotecan) will be screened if sufficient organoids are grown from the biopsy samples within the screening period. Physicians will be informed of the results, and choice of chemotherapy will be based on an IRS score of 70% or above. If more than 1 candidate drug with IRS of 70% or above is identified, the physician will exercise his/her discretion to select the most suitable drug based on patient's comorbidities and organ function.

To evaluate the survival impact of extensive lymphadenectomy as part of debulking surgery in stage IVB ovarian cancer with supradiaphragmatic lymph node metastasis.

This project seeks to develop a quantitative imaging biomarker for evaluating and monitoring treatment response in ovarian cancer metastases and assess its potential in monitoring treatment response. This will involve standardising DW-MRI for the abdomen and pelvis across multiple centres and platforms, assessing reproducibility of the measurement in patients planned for neoadjuvant chemotherapy and assessing its utility as an early response biomarker in patients with platinum-sensitive relapse due to receive therapy with carboplatin. Scanning measurements will be correlated with histopathological markers in tumour samples in order to link the biomarker with response mechanisms.

The purpose of this study is to better understand why women choose to have their fallopian tubes removed as a method for ovarian cancer prevention. This will be done through a paper questionnaire and phone interviews. The investigators hope to gain information that will allow us to better counsel women about ovarian cancer prevention.

Background: Endometrial and ovarian cancers are, respectively, the fourth and eighth most common cancers among women in the United States. Although some routine Pap tests may detect the presence of cancer cells, there are no convincing early detection approaches for either cancer. Better methods of detection are needed. Two possible methods for cancer detection involve samples taken with a tampon or a special kind of brush, called a Tao brush. Researchers would like to know more about how well these methods work. Objectives: To assess the quality of DNA collected by the tampon and Tao brush sampling methods. To detect genetic markers in collected DNA and determine if these markers are related to an individual s cancer status. Eligibility: Women age 45 years and older with confirmed or suspected endometrial or ovarian cancer, who will be having surgery. A control group of postmenopausal women having surgery for benign gynecological conditions will be included. Design: Shortly before hysterectomy or more extensive procedures to treat either cancer or the benign condition: A tampon will be inserted into the vagina to collect cell samples, and removed after 30 minutes. After the tampon is removed, the cervix will be swabbed with the Tao brush to collect cell samples. Following the hysterectomy, samples of healthy and cancerous tissue will be taken, and tested by researchers.

The purpose of this study is to validate a score developed by the AGO-OVAR for complete resection of the tumor

Long-Term Objectives: To establish an ongoing national research registry of epidemiologic, clinical and pathologic data on low grade and low malignant potential (LMP) ovarian cancer patients in UTMDACC's Department of Gynecologic Oncology for research purposes. To create a bank of low grade and LMP ovarian cancer tumor blocks for study of the molecular and histopathologic differences among low grade ovarian cancer, ovarian LMP tumors and high grade ovarian cancer. To specify the epidemiologic and clinical profile of low grade and LMP ovarian cancer patients. To identify potential precursors of low grade and LMP ovarian cancer. To assess treatment patterns to guide management of these diseases. To collect quality of life and health outcomes data on these patients. To achieve a fundamental understanding of low grade and LMP ovarian cancer that will inform prevention and screening efforts, motivate development of improved treatments and eventually result in a cure. The short-term objectives are: To detail procedures for potential registrant identification and recruitment. To create a demographic and health history questionnaire for potential registrants. To begin aggregating low grade and low malignant potential ovarian tumor blocks. To specify a timeline for the development of all other aspects of the Registry.

The association between homologous recombination (HR) gene mutations and homologous recombination deficiency (HRD) status in Chinese epithelial ovarian cancer (EOC) patients is little known. This study would recruit 400 Chinese EOC patients with known targeted gene mutations via a multi-panel testing of 27 genes, including BRCA1/BRCA2. All patients accept evaluation of HRD model, which 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, and a potential explanation of platinum-resistance in such population.

Molecular alterations in Homologous Recombination Repair (HRR) genes have been associated with clinical benefit from chemotherapy and/or Poly (ADP-ribose) polymerase (PARP) inhibitors in patients with epithelial ovarian cancer. Therefore, the performance of tumor molecular profiling is currently recommended by international guidelines at initial diagnosis, among other reasons, for the modification of the treatment plan. The investigators' hypothesis was that tumor molecular profiling reveals additional parameters that can improve the predictive and prognostic role of the mere presence of HRR gene mutations. The study aimed to investigate the prognostic and predictive role of clonality of pathogenic variants in HRR genes and/or concurrent pathogenic variants in other clinically relevant genes.
