Clinical Trial Summary

The treatment efficacy for stage IVb esophageal cancer has been improved through chemotherapy combined with immunotherapy recently.

On this basis, the investigators intend to conduct a prospective, multicenter phase III clinical trial to assess whether radiotherapy with concurrent chemotherapy and immunotherapy could further improve the survival of patients with metastatic esophageal cancer.

Accompanied tissue samples, blood samples and urine samples will be analyzed by molecular biological detection (Including Whole Exome Sequencing and proteomics) to explore potential biomarkers for predicting outcomes, efficacy and toxicity.

Description:

Esophageal cancer (EC) is one of the most common carcinomas with high morbidity and mortality worldwide. More than 30% of the patients were stage IV when diagnosed. Fluoropyrimidine plus platinum-based chemotherapy is recommended as first-line treatment for patients with metastatic EC for approximately four decades, however, only minimal improvement has been reached in overall survival (OS).

Recently, immune checkpoint inhibitors have shown effective antitumor activity in patients with unresectable, advanced or metastatic EC. Several randomized trials have demonstrated the PD-1 inhibitor could further improve the OS in patients with advanced esophageal squamous cell carcinoma (ESCC) on the basis of chemotherapy. Chemotherapy combined with immunotherapy has become one of the the standard treatment modality for advanced EC.

As reported, for the patients with metastatic lung cancer or EC, locoregional radiotherapy could improve survival. However, high-level evidence is still needed to assess whether these patients can benefit from local radiotherapy.

The efficacy of immunotherapy combined with chemotherapy is obviously better than that of chemotherapy alone. On this basis, locoregional radiotherapy may help some patients with advanced EC improve local control, relieve the local symptoms and improving the quality of life.

Therefore, the investigators intend to conduct a prospective, multicenter phase III trial to assess the efficiency and safety of radiotherapy with chemotherapy and immunotherapy of patients with metastatic EC. Accompanied tissue samples, blood samples and urine samples will be analyzed by molecular biological detection to explore potential biomarkers for predicting outcomes, efficacy and toxicity.

Biological:
• PD-1 inhibitor
Camrelizumab (200mg, d1, Q3W) was continued until disease progression, unacceptable toxicity, death, physician or patient decision to withdraw, non-compliance, or discontinuation for administrative reasons (up to 35 cycles).
