Brief Summary

The incidence and mortality of esophageal cancer are at the forefront in China, among which the elderly patients account for a large proportion. Concurrent chemoradiotherapy is the standard treatment for inoperable locally advanced esophageal cancer. Most elderly patients with esophageal cancer cannot tolerate concurrent chemotherapy because of complications and other reasons. Immunotherapy has definite efficacy and low toxicity in advanced esophageal squamous cell carcinoma, and the results combined with radiotherapy have also been preliminarily reported. Therefore, it is necessary to further explore the efficacy and safety of radiotherapy combined with immunotherapy in elderly patients with esophageal cancer.
