Combining Tislelizumab and S-1 for Esophageal Cancer Treatment

The Efficacy of Tislelizumab Combined With S-1 in Patients With Residual Primary Lesions and Node-Negative Esophageal Squamous Cell Carcinoma After Neoadjuvant Immunochemotherapy Followed by Curative Resection: A Phase II, Multicenter Trial

Phase 2 Interventional Daping Hospital and the Research Institute of Surgery of the Third Military Medical University · NCT06354140

This study is testing a new combination of two drugs, Tislelizumab and S-1, to see if it can help patients with esophageal cancer who have had surgery and still have some cancer left.

What this trial studies

This clinical trial investigates the safety and efficacy of combining Tegafur (S-1) with Tislelizumab in patients who have undergone radical resection for esophageal squamous cell carcinoma and have residual disease without lymph node involvement. The study aims to improve treatment outcomes for patients who have received neoadjuvant immunotherapy and chemotherapy. By focusing on patients with ypT1-4N0M0 staging, the trial seeks to explore a novel therapeutic approach in a population that has limited treatment options post-surgery.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-75 with ypT1-4N0M0 esophageal squamous cell carcinoma who have undergone radical resection and received neoadjuvant immunotherapy and chemotherapy.

Not a fit: Patients with other malignancies within the past five years or those with contraindications to chemotherapy or immunotherapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could enhance survival rates and quality of life for patients with esophageal squamous cell carcinoma.

How similar studies have performed: While the approach of combining immunotherapy with chemotherapy is gaining traction, this specific combination of Tislelizumab and Tegafur in this patient population is relatively novel and has not been extensively tested in prior studies.
