[Two Cases of Conversion Surgery for Stage ⅣB Esophageal Cancer after Successful Immune Checkpoint Inhibitor (ICI) Therapy].

The 12th edition of the Management of Esophageal Cancer guidelines recommends a regimen that includes immune checkpoint inhibitor(ICI)therapy as the primary treatment for Stage ⅣB esophageal cancer, which increases the number of treatment options. Surgical intervention at the appropriate time may improve patient prognosis. Here, we describe 2 cases of conversion surgery for patients with Stage ⅣB esophageal cancer who were successfully treated with ICI therapy. The number of patients for whom ICI can be incorporated into multimodal treatments and conversion surgeries is expected to increase in the future.
