Filter by:This registry has the following objectives. First, according to the guidance of 2021 WHO of CNS classification, we constructed and externally tested a multi-task DL model for simultaneous diagnosis of tumor segmentation, glioma classification and more extensive molecular subtype, including IDH mutation, ATRX deletion status, 1p19q co-deletion, TERT gene mutation status, etc. Second, based on the same ultimate purpose of liquid biopsy and radiomics, we innovatively put forward the concept and idea of combining radiomics and liquid biopsy technology to improve the diagnosis of glioma. And through our study, it will provide some clinical validation for this concept, hoping to supply some new ideas for subsequent research and supporting clinical decision-making.
The aim of this study is to investigate and possibly validate urinary biomarkers for prostate cancer. During this study the focus will be on aberrations of selected genes as prognostic or predictive value has been shown for these genes in tissue, CTC or blood derived cfDNA. Proteins will be explored in urine as well. This is a prospective study in which urine samples will be collected from healthy volunteers and urine samples and a blood sample from cancer patients with prostate cancer. The participants will be asked to provide a urine sample collected with the ColliPee® device and fill out an online questionnaire to collect usability data. Thereafter, the urine sample will be aliquoted to be used in the study to investigate the different urinary analytes.
The aim of this study is to evaluate and optimize protocols for the isolation and analysis of analytes in urine (cell-free nucleic acids, extracellular vesicles and proteins). The following factors will be evaluated (1) volumetric collection with Colli-Pee®, a collection device developed by Novosanis for standardized collection of urine, and (2) stabilization methods. This is a prospective study in which urine samples will be collected from healthy volunteers, urine samples and a blood sample from pregnant women and cancer patients with solid tumors with emphasis on breast- and prostate cancer. The participants will be asked to provide a urine sample collected with the Colli-Pee® device and fill out an online questionnaire to collect usability data. Thereafter, the urine sample will be aliquoted to be used in different pilot studies for the protocol optimization. For the pilot study where the effect of volume will be assessed, participants will be requested to collect multiple samples with different Colli-Pee® variants and fill out questionnaires accordingly.

The purpose of this study is to evaluate the safety and efficacy of targeted blood brain barrier disruption with Exablate Model 4000 Type 2.0/2.1 for liquid biopsy in subjects with suspected Glioblastoma brain tumors
Based on the previous study of NCT04651738, we performed this trial to further confirm the accuracy of host DNA CDO1 and CELF4 methylation for endometrial cancer screening in a multi-center cohort. Thirteen hospitals, including Peking Union Medical College Hospital, would enroll eligible patients in this study. The cervical cytology of 3 ml will be collected for the detection of DNA CDO1 and CELF4 methylation, and the results will compared with the endometrial histological pathology, which is achieved after collection of cervical cytology, by surgeries including hysteroscopy, dilation and curettage, total hysterectomy and others. The methylation testing would be double-blinded in operators and analysts. The study will enroll at least 10,000 patients.
This is a multi-centre, prospective cohort study, aiming to evaluate a blood test in early detection of the four common cancers, based on the investigation of the circulating tumour DNA (ctDNA). Primary objective: To evaluate the performance characteristics of the blood ctDNA test in early detecting cancers. Secondary objectives: - To evaluate the performance characteristics of the test in determining the origin of tumour, as compared to the findings of the imaging diagnostic tests. - To determine the risk of cancers development in the high-risk population, as compared to that in the moderate-risk group.
The study is perfomed with adult patients with non-small cell lung cancer treated with tyrosine kinase inhibitor. The objective is to collect repeated samples of blood from patients (starting) on a tyrosine kinase inhibitor, for liquid mutation testing, and pharmacokinetic analysis.
Background: Accessing brain tumor material for pathological diagnosis requires invasive procedures that carry risk to patients including brain hemorrhages and death. Liquid biopsies are emerging non-invasive alternatives to direct tumour biopsies but the abundance of circulating tumor DNA (ctDNA) is relatively low and this limits our ability to accurately make the molecular diagnosis of brain tumors. We have recently shown promising results that suggest that the analysis of blood samples can distinguish brain tumor types. We now want to couple liquid biopsies with high intensity focused ultrasound (HIFU) to enhance the release of tumor DNA into the circulation and increase the sensitivity/and specificity of liquid biopsies for brain tumors. The aim of this project is to build on our preliminary findings and investigate the the time dependent changes associated with HIFU of a tumor to see if it improves accuracy of diagnosis and specifically molecular subtyping of tumors based on peripheral blood and cerebrospinal fluid (CSF) circulating tumor derived markers following HIFU.
Routine clinical and radiological assessment of response of patients with rectum cancer to neoadjuvant chemoradiotherapy does not allow accurate identification of complete pathological response, and leads to frequent false positive and negative results. Molecular markers reflecting the initial and post-nCRT status of the tumor would be ideal to select patients eligible for organ preservation. This project will test the detection of tumor extracellular vesicles (EVs) in liquid biopsy as a reliable marker for the identification of poor versus good responders to nCRT.
