WebApr 10, 2024 · Circulating tumour DNA (ctDNA) is a new biological parameter not yet widely used in clinical practice. CtDNA is being increasingly studied as a potential new strategy for lymphoma profiling and patient management. Circulating cell-free DNA (cfDNA) refers to extracellular DNA fragments present in the body fluid.
WebMay 6, 2024 · Preoperative ctDNA was detected in >90% of patients with pStage II–III. Post-operative (4w) ctDNA status was significantly associated with certain known clinicopathological risk factors for recurrence. ctDNA positivity was associated with a very short -term of recurrence. Sensitivity of relapse detection at 12 weeks was 92% in post - WebMay 3, 2024 · Circulating tumor DNA (ctDNA), representing DNA shed from tumor cells into the circulation, is a versatile blood-based biomarker that can provide real-time assessment of cancer burden. It has been shown in a previous small study of 18 patients that ctDNA detection after surgery for CRLM is highly predictive of eventual cancer relapse.
