Key inclusion & exclusion criteria

Age minimum	>= 20age old
Age maximum	Not applicable
Gender	Both
Include criteria	- The patient was histologically diagnosed with esophageal cancer (squamous cell carcinoma, adenocarcinoma, etc.) by endoscopic biopsy of the primary esophageal lesion, and had a lesion capable of local injection. - The center of esophageal lesions (primary lesion, intramural metastasis, intraepithelial extension) is located in the thoracic esophagus (8th edition of UICC-TNM). However, if the center of the lesion is more distal than the line 2 cm proximal to the esophagogastric junction (the lower end of the palisade vessels seen endoscopically or the upper edge of the gastric mucosal folds), it is not eligible. Esophageal lesions may be single or multiple. - In the 8th edition of UICC-TNM, a cT1N1,cT2-3N0-1 of cT1N2,cT2-3N0-2 and adenocarcinoma of squamous cell carcinoma without distant metastases was made. - ECOG Performance Status (PS) is 0 to 2. - Radical esophagectomy is not indicated. - Definitive chemoradiation is not indicated.
Exclude criteria	- Patients with active double cancers that require treatment (synchronous double cancers and metachronous double cancers with a disease-free interval of less than 3 years). However, carcinoma in situ, carcinoma of the pharynx, larynx, carcinoma of the skin, and carcinoma of the prostate that does not require treatment, which are not considered to affect prognosis, are not included in active double cancers. Also, a history of a pathologic stage cancer that has been completely resected with a 3-year relative survival of at least 95% or less is not included in the active double cancer. - The chemotherapy was carried out for esophageal cancer in the past. - Immune checkpoint inhibitors were used in the past. - If you have previously received radiotherapy for cervical, thoracic and upper abdominal lesions.
