Summary

Neoadjuvant ChemoRadioTherapy (NCRT) combined with surgical resection is the standard treatment for locally advanced esophageal squamous cell carcinoma (ESCC) based on CROSS and 5010 study. However, the recurrence and metastasis rate after neoadjuvant therapy is still very high, reaching about 40%, which seriously affects the long-term survival of patients after surgery. Therefore, how to improve the neoadjuvant therapy regimen, thereby increasing the pCR rate of ESCC patients, eliminating micro metastases and prolonging survival, has always been an urgent problem to be solved in clinical practice. The combination of neoadjuvant chemotherapy and immunotherapy significantly improved the perioperative outcomes of ESCC patients, and the safety and efficacy of the chemoimmunotherapy were validated in the population of locally advanced ESCC patients (Keystone 001 and ESCORT-NEO study). The Ivonescimab Injection is an IgG1 subtype humanized bispecific antibody that targets human vascular endothelial growth factor-A (VEGF-A) and programmed death protein-1 (PD-1). It can simultaneously bind to VEGF-A and PD-1, competitively block the interaction between VEGF-A, PD-1 and their ligands, and exert immune and anti angiogenic effects. This innovative antibody structure design effectively reduces the side effects and enhances the safety of the drug therapy. A few clinical trials (HARMONi-A and HARMONi-2study) suggest that the combination therapy of Ivonescimab and chemotherapy for locally advanced ESCC may be safe and effective, and is expected to achieve better therapeutic effects than neoadjuvant chemoimmotherapy. This study aims to explore the safety and efficacy of Ivonescimab combination with chemotherapy in the treatment of locally advanced resectable ESCC (cII-III stage), and analyze the feasibility of this treatment regimen. At the same time, a comprehensive analysis and detection of the tumor immune microenvironment, circulating immune cells, and circulating tumor DNA (ctDNA) in ESCC were conducted to elucidate the role of immune status and dynamic changes in ctDNA for predicting therapeutic efficacy and prognosis.
