Filter by:This is a prospective, multicenter, observational, single-blinded controlled study. Dynamic monitoring of patients with resectable colorectal cancer was performed using the previously established colorectal tumor-specific plasma ctDNA methylation markers (Multigene methylation detection). Dynamic monitoring of plasma ctDNA methylation before and after treatment and at regular follow-up in patients with colorectal cancer after radical resection of tumor, to explore the predictive effect of postoperative plasma ctDNA methylation on postoperative recurrence and whether dynamic monitoring of postoperative ctDNA methylation could be earlier than imaging examination to indicate tumor recurrence.
Breast cancer is the most common malignant tumor in women worldwide,and there exist a large part of patients need to receive neoadjuvant chemotherapy(NAC) before the curative surgery.Circulating tumor DNA(ctDNA) is the circulating free DNA in the blood that originates from cancers,and it can be detected by modern technologies in plasma.In this prospective study,investigators aim to observe the correlation between tumor response to neoadjuvant chemotherapy and ctDNA.
Application of circulating tumor DNA detection in diagnosis and treatment of locally advanced rectal cancer. First, to explore the feasibility of ctDNA as a detection index for rectal cancer. Second, evaluate the accuracy of ctDNA detection in rectal cancer. Third, to explore whether ctDNA can be used in the evaluation of preoperative concurrent chemoradiotherapy, so as to provide guidance for subsequent treatment. Fourth, to explore the guidance value for the decision of postoperative adjuvant therapy and the frequency of reexamination. Fifth, search for possible recurrence related mutations.
Response evaluation with FDG-PET and free circulating DNA in patients with inoperable lung cancer of non small cell type during first treatment with chemotherapy or immunotherapy.
Foundation Medicine Inc. (FMI) is interested in studying the concordance of genomic alterations between primary and/or metastatic surgical biopsies, and circulating tumor DNA (ctDNA) within different solid tumor types and has been developing an assay in order to do so.
