NCT ID: NCT04651920 Completed - Clinical trials for Epithelial Ovarian Cancer

A Study on Association Between HR Genes and the HRD Status in Chinese Epithelial Ovarian Cancer

Start date: November 26, 2020
Phase:
Study type: Observational

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.

NCT ID: NCT04561050 Completed - Bleeding Clinical Trials

Prediction of Massive Transfusion in Trauma Patients

MTP
Start date: August 1, 2020
Phase:
Study type: Observational

Since the 2000s, many prognostic scores were developed to predict traumatic haemorrhage. Most of these studies were retrospectives based on registers. Due to missing data on death due to bleeding, these studies chose to predict the massive transfusion risk as a surrogate of haemorrhagic death. These scores include clinical parameters (vital signs), laboratory values (Haemoglobin, lactate, Base excess) and/or imaging (CT or ultrasound) values. The scores showing best performance are the Trauma Associated Severe Haemorrhage (TASH) score, developed and validated on the German register (DGU-Register) and the ABC score developed and validated in the United States of America. However, the majority of these scores cannot be applied at the trauma scene due to the unavailability of laboratory and imaging values. Therefore, their clinical utility remains unclear. To overcome the need for diagnostic tests, authors have developed and recently validated a clinical prognostic score in identifying trauma patients with, or at risk of, significant haemorrhage based on predicted probabilities of death due to bleeding: BATT score. This score was developed from an international cohort using data from 271 Trauma Centres in 41 countries on 5 continents and uses first clinical parameters at initial assessment. The BATT score predicts death due to bleeding and has been validated on a large population in England and Wales. It could also predict massive transfusion, as a surrogate of haemorrhagic death, earlier at the trauma scene. Its feasibility and external validation would make its clinical utility superior to other scores while identifying a greater number of patients requiring early management. Our study is an external validation of pre-existing prognostic scores of traumatic haemorrhages (TASH , ABC and BATT score) at different times of care (Scene of Injury, admission at the trauma room) in order to assess their overall performance, discrimination and calibration in the prediction of massive transfusion, and haemorrhagic death. The objective of the study is to assess a comparison of score performances (Overall performance, discrimination and calibration). Due to the study population (STR), which is partly integrated into the German DGU-Register, the investigators expect good transportability of the TASH score to the Swiss Trauma Registry in terms of overall performance, discrimination and calibration. The ABC score should show lowers results in terms of discrimination due to its validation on small cohorts exclusively in North America. The new BATT score predicting death due to bleeding has been validated on a large English cohort of more than 100,000 patients. It identifies all patients with haemorrhage and not only patients who have received a massive transfusion subject to survival bias. In this context, the BATT score provides good discrimination with only simple physiological variables available at the trauma scene. In case of its external validation on the STR as part of our study, its feasibility would make its clinical utility superior to other pre-existing scores, while identifying a greater number of patients requiring early management. Its application would activate a massive transfusion plan directly at the trauma scene and save precious time.

NCT ID: NCT04460625 Completed - Critical Illness Clinical Trials

Effect of Blood Group on the Survival Status of Intensive Care Patients

Start date: May 1, 2020
Phase:
Study type: Observational

The research was planned to determine the effect of different blood groups on the 90-day survival of intensive care patients who were treated and maintained for the first time in the intensive care unit. The research is a retrospective descriptive research. For the first time in an intensive care unit aged 18 and over, between January 1, 2014 and December 31, 2019, of a state and a university hospital in the Western Black Sea Region, in intensive care units (both medical and surgical patients), All the patients, who were hospitalized in the intensive care unit for at least 24 hours, were discharged from the intensive care unit for 90 days and less, and all the information in the Patient Information Form can be accessed from the automation system. The research will be conducted between 01.04.2020-01.07.2020 by collecting the necessary data within the 'Patient Information Form' of the patients from the information processing unit of the hospitals where the research will be conducted.

NCT ID: NCT03742063 Completed - Prognosis Clinical Trials

Clinical Evaluation of Neoadjuvant Chemotherapy for Primary Malignant Sarcomas That Originate in Bone

CESOFB-00
Start date: June 1, 2017
Phase:
Study type: Observational

For bone lesions treated with chemotherapy or targeted therapy, particularly for sarcomas that originate in bones, Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 is spurious because bone lesions are typically located in irregularly shaped bones, are difficult to measure accurately, and usually respond more slowly to treatment than soft tissue lesions. Positron Emission Tomography Response Criteria in Solid Tumors (PERCIST) allows for response to be measured in the absence of anatomic changes through assessment of metabolic activity. It does not, however, account for morphologic changes. This study evaluated whether clinical imaging findings of sarcomas after preoperative chemotherapy correlate with tumor responses by pathological evaluation using the rate of necrosis to develop reliable and quantitative clinical response criteria.

NCT ID: NCT03740425 Completed - Clinical trials for Aortic Valve Stenosis

Transfusion Requirements in Transcatheter Aortic Valve Implantation (TRITAVI) Study

TRITAVI
Start date: January 1, 2018
Phase:
Study type: Observational

Periprocedural bleeding events are frequent during transcatheter aortic valve implantation (TAVI), mainly driven by vascular complications and are associated to a worse prognosis. Therefore, red blood cell (RBC) transfusion is often required, although it is associated with worsened outcomes. There is no consensus on the optimal transfusion strategy after bleeding. The Transfusion Requirements in Transcatheter Aortic Valve Implantation (TRITAVI) will be a multicenter retrospective registry enrolling consecutive patients who underwent TAVI; the primary aim of the study will be to test whether RBC transfusion is a marker or an independent predictor of adverse events.

NCT ID: NCT03652402 Completed - Clinical trials for Kidney Transplantation

EU-TRAIN
Start date: November 27, 2018
Phase:
Study type: Observational

Main objective: To design a precision risk stratification system that predicts individual risk of rejection

NCT ID: NCT03437837 Completed - Breast Cancer Clinical Trials

Validation of the CPS+EG, Neo-Bioscore and Modified Neo-Bioscore Staging Systems After PST of BC in China

Start date: May 1, 2017
Phase:
Study type: Observational

Prognostic assessment after preoperative systemic therapy (PST) plays a vital role in breast cancer patients. The clinical-pathologic staging system incorporating estrogen receptor (ER)-negative disease and nuclear grade 3 tumor pathology (CPS+EG staging system) can effectively predict prognosis after PST. The Neo-Bioscore has been developed by the incorporation of the human epidermal growth factor receptor 2 (HER2) status into the CPS+EG staging system. But in a real world in China, the both staging systems had limits because of trastuzumab administration varied a lot in China from the United States. This retrospective study will validate CPS+EG and Neo-Bioscore system and explored a modified Neo-Bioscore system in multiple centers.

NCT ID: NCT03268096 Completed - Multiple Sclerosis Clinical Trials

Disability, MRI Lesions and Thickness of Retinal Fibers: Evaluation 15 Years After a First Episode of Demyelination

DB-SEP15
Start date: May 3, 2017
Phase:
Study type: Observational

Knowledge of the evolution of multiple sclerosis (MS) and its long-term prognostic factors is essential to guide the therapeutic management. However, it remains partial and concerns above all data collected during the first years of the disease. The evolution towards disability can only be assessed after a follow-up of more than 10 years and does not depend solely on the initial inflammatory activity of the disease. We propose to realize a standardized clinical assessment, an optical coherence tomography (OCT) and a cerebral MRI 15 years after the first clinical manifestation of the disease. Clinical and paraclinical assessment will consist in the realization of additional MRI sequences in order to obtain more precise information on cerebral lesions (unconventional parameters). Optical coherence tomography (new generation device) will also be performed on both eyes to describe the thickness of the different layers of the retina. A clinical evaluation will be performed with the Expanded Disability Status Scale (EDSS). This study aims: 1. to describe the current clinical situation of patients (e.g. percentage of patients with moderate or severe disability) 2. to explore the associations between MRI parameters, those measured with OCT and clinical characteristics (disability) 3. to explore clinical and paraclinical prognostic factors of pejorative evolution (disability, severe cerebral atrophy, etc.)
