| Summary | Patients diagnosed with locally advanced esophageal squamous cell carcinoma (ESCC) that is deemed unresectable face a bleak prognosis. Recent phase 1/2 studies have demonstrated the efficacy and safety of augmenting neoadjuvant concurrent chemoradiotherapy with immunotherapy in treating resectable ESCC. The present study is a prospective, 3-arm, randomized trial that seeks to evaluate the efficacy of diverse conversion therapy modalities in patients with unresectable ESCC. The study objectives include R0 resection rate, treatment-related adverse events, morbidity and mortality, 1-year progression-free survival (PFS), and 1-year overall survival (OS) rates. Tislelizumab is a humanized IgG4 monoclonal antibody with high affinity/specificity for programmed cell death protein 1 (PD-1). Tisleli |
