Camrelizumab, Chemotherapy and Ivarmacitinib in Patients With Resectable Esophageal Squamous Cell Carcinoma

In the management of locally advanced esophageal squamous cell carcinoma, the outcomes associated with surgical resection, whether conducted alone or supplemented with postoperative adjuvant radiotherapy and chemotherapy, have been suboptimal. The high risk of local recurrence and distant metastasis, which affect patient prognosis and survival rates. Preoperative immunotherapy holds the potential to activate the patient's immune system to recognize tumor antigens and establish immune memory, thereby enabling the immune system to maintain its surveillance role following surgical tumor resection. Consequently, there is a growing emphasis on the administration of immunotherapy prior to surgery across various solid tumor types. Immune checkpoint inhibitors (ICIs) have shown potential in enhancing the immune system's capacity to target and eliminate cancer cells. However, a substantial subset of patients either responds inadequately or develops resistance to these therapies. To address this challenge, numerous combination treatment strategies have been explored in clinical research. Evidence suggests that the concurrent administration of JAK inhibitors with ICIs may improve anti-cancer efficacy, increase patient response rates, and prolong progression-free survival compared to ICIs alone. Notably, there is a paucity of research regarding the combination of camrelizumab with chemotherapy and Ivarmacitinib as a neoadjuvant therapy. This prospective, exploratory study aims to assess the efficacy of combining camrelizumab, chemotherapy, and Ivarmacitinib in neoadjuvant treatment for locally advanced esophageal squamous cell carcinoma, with the objective of broadening therapeutic options for this malignancy.
