Inclusion criteria

Inclusion criteria: The primary tumor is located at either the cervical, thoracic esophagus, or esophagogastric junction (UICC-TMN 8th edition). Histopathologically diagnosed as squamous cell carcinoma, adenosquamous cell carcinoma, basaloid carcinoma, or adenocarcinoma. Planned treatment (excluding palliative treatment) for untreated esophageal cancer with distant metastasis (distant organ metastasis or distant lymph node metastasis). he presence of distant metastasis (distant organ metastasis or distant lymph node metastasis) has been confirmed by imaging (CT, MRI or PET) or histopathologically. Distant metastatic organs shall be liver/lung, bone, brain, etc., regardless of number, size, or distribution. Distant lymph nodes are regional extraneous lymph nodes, excluding supraclavicular and intramediastinal lymph nodes. Duplication of distant metastatic organs and distant lymph nodes is allowed. Examples of distant metastatic organs of esophageal cancer Liver, lung, lymph node, bone, brain, adrenal gland, skin, muscle, peritoneum, pleura, pericardium, etc. Age: 20 years old or older ALT less tahn 100 IU/L Creatinine clearance more than 40ml/min (Cockcroft-Gault formula) Patients with a prognosis of 3 months or longer Patients who have given their consent to participate in the study
