Brief Summary: The goal of this project is to recruit 50 patients who have locally advanced esophageal squamous cell carcinoma and have undergone neoadjuvant and adjuvant therapy, followed by surgical resection. Initially, tumor tissues from all patients will undergo a more comprehensive NGS sequencing process (WESPlus) than whole-exome sequencing. This will provide a complete genomic mutation profile for each patient. Subsequently, a specific algorithm will be used to accurately select 20 mutation sites as the patient's unique "molecular label." Additionally, 21 critical driver genes related to tumors will be combined, leading to the creation of an exclusive MRD probe. This will enable ultra-high-depth capture sequencing of ctDNA samples from patients at 100,000x. By continuously monitoring each patient's ctDNA dynamics, changes in ctDNA concentration or ctDNA-MRD negative/positive results will serve as the primary indicators to assess the efficacy and prognosis of patients with esophageal squamous cell carcinoma.
