About this trial
Esophageal cancer remains a disease with a poor prognosis. Chemotherapy is an important part of its treatment, but there are cases in which chemotherapy is ineffective. The investigators aim to develop a model to predict the response to chemotherapy by DNA methylation of preoperative biopsy specimens to identify the chemotherapy ineffective group.
