U.S., April 9 -- ClinicalTrials.gov registry received information related to the study (NCT07517107) titled 'Dynamic Circulating Tumor DNA Monitoring to Guide Systemic Therapy in Gastric Cancer' on April 01.
Brief Summary: This study aims to evaluate the clinical value of circulating tumor DNA (ctDNA) as a minimally invasive biomarker for monitoring treatment response and guiding systemic therapy in patients with gastric or gastroesophageal junction adenocarcinoma.
Gastric cancer is often diagnosed at an advanced stage and shows substantial biological heterogeneity. Current treatment decisions mainly rely on imaging and clinical assessment, which may not reflect early molecular changes or minimal residual disease. Circulating tumor DNA, r...
