U.S., Jan. 28 -- ClinicalTrials.gov registry received information related to the study (NCT07371247) titled 'Based on ctDNA-MRD Guided Adjuvant Treatment Escalation After Definitive Chemoradiotherapy for Unresectable Locally Advanced Esophageal Squamous Cell Carcinoma: a Study on Safety and Efficacy' on Jan. 19.

Brief Summary: Numerous studies have confirmed that ctDNA-MRD detection technology based on peripheral blood can identify minimal residual disease (MRD) following surgery and other curative treatments, indicating a higher risk of recurrence. Multiple exploratory studies in esophageal cancer have demonstrated that patients who are ctDNA-MRD positive after definitive chemoradiotherapy (dCRT) exhibit poorer progression-free survival (...
