Condition: Esophageal Squamous Cell Carcinoma · Sponsor: Sun Yat-Sen University Cancer Center
The goal of this observational study or is to explore the correlation between dynamic changes in postoperative circulating tumor DNA (ctDNA) and recurrence risk using a novel, tumor-informed ctDNA detection technique, thus laying the foundation for further promoting ctDNA detection to guide postoperative adjuvant therapy decisions. This study focuses on patients with esophageal squamous cell carcinoma who did not achieve pCR following neoadjuvant therapy combined with surgical resection. The main question it aims to answer is: Is there a correlation between postoperative ctDNA changes and tumor recurrence? Participants will be asked to undergo postoperative ctDNA detection.
