About
China with high incidence of esophageal cancer, the number of new cases and deaths account for about 50% of the world every year. In the past few decades, surgery, radiotherapy, chemotherapy and other treatments were continuously improved, however, the mortality of esophageal squamous cell carcinoma patients was not significantly decreased.
For patients with locally advanced esophageal cancer, direct surgery is not effective. It is difficult to achieve radical resection by surgery merely, and even if many patients receive surgery, they may eventually have tumor recurrence and poor survival rate. Therefore, it is necessary to explore effective perioperative neoadjuvant treatment to reduce the risk of postoperative recurrence and improve the postoperative survival rate of patients.
According to the reports, the expression of PD-L1 in esophageal cancer was about 41.4%. Therefore, PD-1/ PD-L1 immunocheckpoint inhibitor may become a new method for the treatment of esophageal cancer. Preliminary clinical results showed that immunotherapy combined with chemoradiotherapy provided a synergies antitumor effect. Multiple clinical results showed that Carrillizumab provided higher overall response rate for advanced esophageal cancer.
However, in patients with locally advanced esophageal cancer, the efficacy of Carrillizumab combined with chemotherapy and apatinib for sequential radical surgery is still unclear. The purpose of this study is to observe and evaluate the efficacy and safety of Carrillizumab combined with chemotherapy and antiangiogenic drugs in the neoadjuvant therapy of resectable esophageal squamous cell carcinoma.
Full description
Esophageal cancer is a common malignant tumor of the digestive tract. Every year, there are about 400,000 new cases of esophageal cancer in the world and about 300,000 people dying of this disease. China with high incidence of esophageal cancer, the number of new cases and deaths account for about 50% of the world every year. In the past few decades, surgery, radiotherapy, chemotherapy and other treatments were continuously improved, however, the mortality of esophageal squamous cell carcinoma patients was not significantly decreased. Early local invasion, lymph node metastasis and distant metastasis are the main causes of poor prognosis for the patients with esophageal squamous cell carcinoma.
For patients with locally advanced esophageal cancer, direct surgery is not effective. It is difficult to achieve radical resection by surgery merely, and even if many patients receive surgery, they may eventually have tumor recurrence and poor survival rate. Therefore, it is necessary to explore effective perioperative neoadjuvant treatment to reduce the risk of postoperative recurrence and improve the postoperative survival rate of patients.
In recent years, PD-1 antibody is undoubtedly the most dazzling star in the field of tumor therapy. It shows excellent efficacy in of the different kind of tumors. According to the reports, the expression of PD-L1 in esophageal cancer was about 41.4% (Meta-analysis of 1350 Chinese and Japanese subjects showed that the over-expression of PD-L1 tended to decrease overall survival). Therefore, PD-1/ PD-L1 immunocheckpoint inhibitor may become a new method for the treatment of esophageal cancer. Preliminary clinical results showed that immunotherapy combined with chemoradiotherapy provided a synergies antitumor effect. Multiple clinical results showed that Carrillizumab provided higher overall response rate for advanced esophageal cancer. It also provided superior progression free survival and overall survival compared with Pembrolizuma and paclitaxel. 2020 Chinese Society Of Clinical Oncology esophagus cancer guidelines recommended Carrillizumab as the first level for squamous cell carcinomas.
However, in patients with locally advanced esophageal cancer, the efficacy of Carrillizumab combined with chemotherapy and apatinib for sequential radical surgery is still unclear. The purpose of this study is to observe and evaluate the efficacy and safety of Carrillizumab combined with chemotherapy and antiangiogenic drugs in the neoadjuvant therapy of resectable esophageal squamous cell carcinoma.
