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 %.

BackgroundGlobalization of the professions has become a necessity among schools and universities across the world. It has affected the medical and dental professions in terms of curriculum design and student and patient needs. In Japan, where medicine and dentistry are taught mainly in the Japanese language, profession-based courses in English, known as Medical English and Dental English, have been integrated into the existing curriculum among its 83 medical and 29 dental schools. Unfortunately, there is neither a core curriculum nor a model syllabus for these courses.MethodsThis report is based on a survey, two discussion forums, a workshop, and finally, the drafting of a proposed core curriculum for dental English approved by consensus of the participants from each university.ResultsThe core curriculum covers the theoretical aspects, including dental English terms and oral pathologies; and practical aspects, including blended learning and dentist-patient communication. It is divided into modules and is recommended to be offered for at least two semesters.ConclusionsThe core curriculum is expected to guide curriculum developers in schools where dental English courses are yet to be offered or are still in their early development. It may also serve as a model curriculum to medical and dental schools in countries in Asia, Europe, Africa, and Central and South America, where English is not the medium of instruction.Electronic supplementary materialThe online version of this article (doi:10.1186/s12909-014-0239-4) contains supplementary material, which is available to authorized users.
