Abstract
Background
Esophageal cancer is the eighth most common cause of cancer mortality in Japan. More than 11,000 people had died from esophageal cancer in 2018. The Japan Esophageal Society has collected the data on patients' characteristics, performed treatment, and outcomes annually.
Methods
We analyzed the data of patients who had first visited the participating hospitals in 2013. In 2019, the data collection method was changed from an electronic submission to a web-based data collection using the National Clinical Database (NCD). Japanese Classification of Esophageal Cancer 10th by the Japan Esophageal Society (JES) and UICC TNM Classification 7th were used for cancer staging
Results
A total of 8019 cases were registered from 334 institutions in Japan. Squamous cell carcinoma and adenocarcinoma accounted for 87.8% and 6.3%, respectively. The 5-year survival rates of patients treated using endoscopic resection, concurrent chemoradiotherapy, radiotherapy alone, or esophagectomy were 88.3%, 32.4%, 24.4%, and 59.3%, respectively. Esophagectomy was performed in 4910 cases. The operative and the hospital mortality rates were 0.77% and 1.98%, respectively. The survival curves showed a good discriminatory ability both in the clinical and pathologic stages by the JES system. The 5-year survival rate of patients with pStage IV in the UICC classification that included patients with supraclavicular node metastasis was better than that of patients with pStage IVb in JES classification.
Conclusion
We hope this report contributes to improving all aspects of the diagnosis and treatment of esophageal cancer in Japan.

Preface 2013
We deeply appreciate the great contributions of many physicians in the registry of esophageal cancer cases. The Comprehensive Registry of Esophageal Cancer in Japan, 2013, was published here. In 2019, the data collection method was changed from an electronic submission to a web-based data collection using the National Clinical Database (NCD). Personal information was replaced with individual management code inside each institute, and the NCD collected only anonymized information. The registry complies with the Act for the Protection of Personal Information.
We briefly summarized the Comprehensive Registry of Esophageal Cancer in Japan, 2013. Japanese Classification of Esophageal Cancer 10th by the Japan Esophageal Society (JES) [1] and UICC TNM Classification 7th [2] were used for cancer staging according to the subjected year. A total of 8019 cases were registered from 334 institutions in Japan. Tumor locations were cervical: 4.8%, upper thoracic: 12.1%, middle thoracic: 46.5%, lower thoracic: 28.2% and EG junction: 7.9%. Superficial carcinomas (Tis, T1a, T1b) were 38.6%. As for the histologic type of biopsy specimens, squamous cell carcinoma and adenocarcinoma accounted for 87.8% and 6.3%, respectively. Regarding clinical results, the 5-year survival rates of patients treated using endoscopic resection, concurrent chemoradiotherapy, radiotherapy alone, or esophagectomy were 88.3%, 32.4%, 24.4%, and 59.3%, respectively. The endoscopic submucosal dissection accounted for 91.6% of endoscopic resection. Esophagectomy was performed in 4910 cases. Concerning the approach used for esophagectomy, 43.0% of the cases were treated thoracoscopically. The operative mortality (within 30 days after surgery) was 0.77%, and the hospital mortality was 1.98%. The Kaplan–Meier survival curves diverged according to the N-grade both in the JES and the UICC classifications. The survival curves showed a good discriminatory ability both in the clinical and pathologic stages by the JES system. However, the survival of cStage IIB was better than those of IB and IIA, while the survival curves were almost identical between cStage IIIc and IV in the UICC system. Also, the survival curve of pStage IIA merged with that of IIB, and the survival of pStage IV was better than that of IIIC. The 5-year survival rate of patients with pStage IV in the UICC classification that included patients with supraclavicular node metastasis was better than that of patients with pStage IVb in JES classification.
We hope that this Comprehensive Registry of Esophageal Cancer in Japan for 2013 will help to improve all aspects of the diagnosis and treatment of esophageal cancer in Japan.
