WebJan 16, 2024 · Serial analysis of circulating tumor DNA (ctDNA) after surgery can identify patients with stage I-III colorectal cancer (CRC) at high risk for recurrence. A prospective study demonstrated that ctDNA can signal relapse far better than carcinoembryonic antigen (CEA) surveillance and earlier than standard radiological imaging ( Abstract 11 ).

ctDNA predicts outcomes in CRC after surgery and ACT
WebJul 31, 2024 · We analyzed ctDNA mutations and concentrations in 47 early- and late-stage CRC patients using a targetted sequencing approach using a panel that covers 50 cancer-related genes. ctDNA mutations in 37 genes were identified in 93.6% of the patients ( n =47). The results showed that TP53, PIK3CA, APC, and EGFR were the most frequently … WebMar 23, 2024 · Axel Grothey, MD.

WebPURPOSE We hypothesized that circulating tumor DNA (ctDNA) molecular residual disease (MRD) analysis without prior mutational knowledge could be performed after neoadjuvant chemotherapy to assess oligometastatic colorectal cancer (CRC) treated surgically with curative intent. We also investigated urine as an alternative analyte for ctDNA MRD … Web18 hours ago · Genomic profiling of >13,000 patients with early (≤50 years old) vs late (≥60 years old) onset CRC Potential of ctDNA to guide imaging-based surveillance strategies in patients after surgery ... WebIn CRC, ctDNA has proven useful as a surrogate marker of minimal residual disease after curative surgery and may offer improvements over conventional diagnostic imaging in assessing residual disease [33,34]. Enhanced detection of residual disease in these patients may help to better select patients for adjuvant treatments including chemotherapy ... the show dog store
