Preface 2009

We deeply appreciate the great contributions of many physicians in the registry of esophageal cancer cases. The Comprehensive Registry of Esophageal Cancer in Japan, 2009 was published here, despite some delay. The registry complies with the Act for the Protection of Personal Information. The encryption with a HASH function is used for ‘‘anonymity in an unlinkable fashion’’.

We briefly summarized the Comprehensive Registry of Esophageal Cancer in Japan, 2009. Japanese Classification of Esophageal Cancer 10th and UICC TNM Classification 6th were used for cancer staging according to the subjected year. A total of 6260 cases were registered from 276 institutions in Japan. Tumor locations were cervical: 4.4 %, upper thoracic: 11.9 %, middle thoracic: 48.0 %, lower thoracic: 27.7 % and EG junction: 6.6 %. Superficial carcinomas (Tis, T1a, T1b) were 36.7 %. As for the histologic type of biopsy specimens, squamous cell carcinoma and adenocarcinoma accounted for 90.5 and 3.8 %, respectively. Regarding clinical results, the 5-year survival rates of patients treated using endoscopic mucosal resection, concurrent chemoradiotherapy, radiotherapy alone, chemotherapy alone, or esophagectomy were 86.2, 27.9, 20.2, 5.8, and 55.9 %, respectively. Esophagectomy was performed in 3844 cases. Concerning the approach used for esophagectomy, 24.9 % of the cases were treated thoracoscopically. The operative mortality (within 30 days after surgery) was 1.01 % and the hospital mortality was 4.76 %.

We hope that this Comprehensive Registry of Esophageal Cancer in Japan, 2009 will help to improve all aspects of the diagnosis and treatment of esophageal cancer in Japan.
