IT Strategic Headquarters of the Japanese government compiled the Priority Policy Program 2007, in which "Establishment of the structure for every citizen to be able to manage and utilize his health information by himself" and "Foundation of the e- Post-Office box for the realization of the social security service in aspects of people" are declared. For this purpose, a health information system is considered that delivers healthcare data to the server, where the data is to be individually self.administered by the owner. A patient can register his data, and download or reference it from any medical institution or home when necessary. We made a prototype system to realize such a personal health data referring system based on the e. post.office box concept. The system is to be used in field trial experiment with the staffs and students of Tokyo Institute of Technology using their ID Card. This prototype system is expected to be available for the policy suggestion in the realization of the e-P.O.Box stated in the Priority Policy Program of the government.

We studied 1809 oral cancer patients who visited and were treated in 2002 at the 148 institutions certified as training facilities by the Japanese Society of Oral and Maxillofacial Surgeons, which is composed of 39 dental university hospitals, 44 medical university hospitals, 64 general hospitals, and 1 unknown institution. The patients consisted of 1071 (59.2 %) males and 738 (40.8 %) females (male:female ratio, 1.45:1), who had a mean age of 65.2 years old. The tongue (40.2 %) was the most common site affected, followed by the gingiva (32.7 %), buccal mucosa (10.1 %), and oral floor (9.0 %). There were 6 cases of intraoral multiple cancer. In histopathological examinations, squamous cell carcinoma (88.7 %) was the most common type found, followed by adenoid cystic carcinoma (2.1 %), and mucoepidermoid carcinoma (1.7 %). In addition, non-epithelial tumors comprised 1.8 % , among which malignant melanoma was the most common type. Cases classified as T2N0 were the most common (32.1 %), followed by T1N0 (21.4 %), T4N0 (8.0 %), and T2N1 (7.6 %). Distant metastasis occurred in 17 patients (1.0 %). The sizes of the non-epithelial malignant tumors ranged from 1.0 to 7.0 cm, with a mean size of 3.7 cm.
