This study aims to look at a comparison of liquid biopsy (blood sample) analysis compared with tissue biopsy in patients with advanced lung cancer
The purpose of his study is to investigate the intra tumor heterogeneity of the primary tumor and the involved lymph nodes from patients with resectable NSCLC, to detect primary tumor genetic alternations using "liquid biopsy" during the patients' clinical follow up and to correlate the "liquid biopsy" information with the disease recurrence.
This study uses a sequence analysis for TWIST and other craniofacial development genes, among patients presenting with facial clefting.
The purpose of this study is to evaluate the mutation patern of EGFR and other TKI targeted gene during TKI treatment of advanced NSCLC patient with liquid biopsy.
Lymphoma is a highly heterogeneous blood malignancy. It is very important to search for relative specific diagnostic markers that can detect related lymphoma in early stage for the treatment and long-term prognosis of the disease, as the hematopoietic diseases, such as lymphoma, are more difficult to biopsy than solid tumors, with more damage and side effects.Liquid Biopsy (Liquid Biopsy) refers to the extraction of solid biological tissue, is the most common blood, also includ...
The purpose of this study is to evaluate the diagnostic and prognostic efficacy of liquid biopsy in different specimens and in different methods compared with tissue detection .
Colorectal cancer (CRC) is among the most preventable cancers when precancerous lesions are detected at an early stage. Current screening methods for CRC require bowel prep or stool-based testing that are inconvenient, resulting in low compliance. Stool based tests have limited sensitivity for the detection of precancerous lesions. The CMx platform has been showed to be able to the detection of Circulating Tumor Cells (CTCs) in high sensitivity and specificity. In published st...
The purpose of this research study is to learn more about changes in cell-free tumor DNA in blood samples, also known as a liquid biopsy, as they relate to treatment and response to treatment.
Condorde main objective is to evaluate the correlation between EGFR mutational status determined after tumor biopsy and EGFR mutational status analyzed on ctDNA after liquid biopsy. EGFR status will be assessed by real time PCR (rtPCR), digital PCR (dPCR) and Next Generation Sequencing (NGS) in patients with chemotherapy naive lung carcinoma.
We aim to analyze whether the "liquid biopsy" model could increase the specificity of detecting men with an aggressive (defined as Gleason score ≥ 7) prostate cancer and thereby reduce the proportion of men who undergo prostate biopsy, while at the same time maintaining the same sensitivity to detect aggressive prostate cancer as the PSA test alone. Using blood and urine biomarkers together with an algorithm, which incorporates the clinical data, we aim to identify patients w...
This study aims to develop a novel, reliable, liquid biopsy-based biomarker system for relapse of HCC associated with hepatitis B after liver transplantation.
The study aims at assessing whether cell free DNA genotyping can improve the accuracy of early prediction of cure in mature B-cell tumor patients and whether it represents an accessible source of tumor DNA for the sensitive identification of genetic biomarkers that refine the diagnostic workup, stratify prognosis and identify the emergence of drug-resistance mutations during treatment.
This specimen collection is designed to obtain whole blood and tumor tissue from subjects diagnosed with cancer for the purpose of the development of a noninvasive liquid biopsy assay using next generation sequencing (NGS).
The purpose of the current study is to establish a Liquid biopsy method (positive enrichment by a novel immunomagnetic beads capture assay) for detection of malignant cell in serous effusions and to evaluate its sensitivity and specificity for clinical application.
In this trial, anti-tumor efficacy of TAGRISSO in NSCLC patients in whom T790 mutations are detected by liquid biopsy.
Study design Prospective multicentre explorative randomized single blinded study to evaluate accuracy of molecular genetic characterisation of NSCLC. Patients with suspected lung cancer are randomized in a 1:1-setting for bronchoscopic tumor tissue either by forceps or by cryobiopsy. Apart from the bronchoscopic techniques liquid biopsy of peripheral blood and if feasible transbronchial needle aspiration with or without endobronchial ultrasound guidance are performed for in all...
Borderline resectable pancreatic cancers represent a wide spectrum of final histologic stages. A patient-tailored treatment plan requires an accurate preoperative staging. Currently more than 40% of patient taken to the OR are actually unresectable and more than one third of resected patient will need a vascular resection, of those approximately an half will eventually have a vascular infiltration. Among patients that meet upfront surgery some would have benefit of a neoadjuva...
This pilot trial studies how well serial liquid biopsies work in detecting microsatellite instability in participants with stage IV colorectal cancer. Serial liquid biopsies may help doctors learn better methods to track cancer in the bloodstream and how to use these to improve cancer treatments.
To evaluate the emergence of RAS mutation in patients with metastatic colorectal cancer, circulating free DNA will be analyzed using mass spectrometric genotyping in subjects during cetuximab treatment. The hypothesis of this study is that acquired RAS mutation is responsible for the resistance to cetuximab treatment in wild-type colorectal cancer. The usefulness of liquid biopsy to monitor dynamic genetic alterations in colorectal cancer during treatment will also be investiga...
Utilization of circulating-tumor-cell (CTC) and cell free DNA (cfDNA) as novel and noninvasive tests for diagnosis confirmation, therapy selection, and cancer surveillance is a rapidly growing area of interest. In the wake of FDA approval of a liquid biopsy test, it is important for clinicians to acknowledge the obvious clinical utility of liquid biopsy for cancer management throughout the course of the disease.
This study will prospectively compare liquid-biopsy based methods for prediction of resistance under androgen-receptor signaling inhibitors. The main goal is to determine the optimal method to determine androgen-receptor variant 7 (AR-V7) status. In addition, we will explore novel other, AR-V7 independent mechanisms of resistance and their predictive value for proper treatment. These are based on further AR splice variants, and on neuroendocrine differentiation of prostate canc...
Purpose: This study outlines the benefits of the proximal tibia angle (PTA) in evaluation of the pre-operative individual condylar twist angle (CTA) in total knee arthroplasty. Methods: Condylar twist angle and proximal tibia angle were obtained from 33 female healthy participants using computed tomography (CT). The CTA, angle between clinical transepicondylar axis and posterior condylar line were measured. The PTA is the angle formed between the mechanical axis of the tibia a...
Circulating tumor DNA (ctDNA) carrying tumor-specific sequence alterations has been found in the cell-free fraction of blood. Hepatocellular carcinoma (HCC) specimens are difficult to obtain, and noninvasive methods are required to assess cancer progression and characterize underlying genomic features. Use of 'liquid biopsy' by assessing circulating cell free DNA enables the clinician to offer targeted immunotherapy or signaling pathway inhibitors. It also offers a model to pro...
The objective of this protocol is to develop an institution-wide liquid biopsy protocol that will establish a common process for collecting blood and corresponding archived tumor specimens for future research studies at the University Health Network's Princess Margaret Cancer Centre. Circulating cell-free nucleic acids (cfNA), including cell-free DNA (cfDNA) and cell-free RNA (cfRNA), are non-invasive, real-time biomarkers that can provide diagnostic and prognostic information ...
The reference technique for the conservation of gametes is storage in liquid nitrogen but new vats of nitrogen vapor (storage over liquid nitrogen) or in dry phase (storage in an insulated compartment of liquid nitrogen in a tank Liquid nitrogen) also allow the storage of flakes. The purpose of this work is to evaluate the dry-phase cryopreservation technique of liquid nitrogen compared with liquid-phase storage, depending on the duration of cryopreservation.
