Establishment of the radiotherapy results improvement methods using web-based database

本研究实现了以下内容。1)建立基于网络的放疗病史调查数据库。起初，我们让由JASTRO数据库委员会管理的放射肿瘤学大区域数据库（ROGAD）在互联网上转移。而且，我们让目的相同的pc和JNCDB也在互联网上转移。我们的目的是优化单个病例的放射治疗方案，为临床质量保证做出贡献，探讨放射治疗对肿瘤破坏的疗效，并评估一种新的放射治疗方法。JNCDB旨在整合所有癌症注册。此外，网上输入申请的目的是提高输入数据的可靠性，减轻登记机构的输入负担，加快信息公开。2)利用某注册机构的医院信息系统（Hospital Information System， HIS）和放射学信息系统（Radiology Information System， RIS），提高随访调查的准确性，从临床信息、检查信息和剂量信息中获取更多信息。3)我们可以像注册机构的协议一样定制一个多机构数据库，从而掩盖数据库的用途、数据项、数据线和结构的差异。在开发的虚拟专用数据库VPDB （Virtual Private Database）上，我们可以像注册一个机构的数据库一样在多个机构的数据库中注册案例。4)我们开发了一个学习系统，该系统可以从过去的生存分析信息中显示针对单个病例优化的治疗方案。5)此外，我们保存了图像数据和文本数据，并可以搜索，能够掌握详细放疗的实际情况。6)通过积累的大量放疗病例登记和某登记机构的结构调查，分析了当前放疗现场存在的问题，并提出了在当前条件下的指导意见。利用基于网络的数据库建立放疗效果改善方法。少

This study realized the following contents. 1) We built the disease history record survey web-based database for radiotherapy. At first we let ROGAD (Radiation Oncology Greater Area Database) which was administered under a database committee of JASTRO shift on Internet. And, we let PCS and JNCDB which have same purposes shift on Internet, too. Our purpose are optimization of radiation treatment planning of an individual case, contribution to clinical Quality Assurance, efficacy investigation to cancer destruction by radiotherapy, and evaluation of a new radiotherapy. JNCDB aims integration of all cancer registration. In addition, the aims of on-line input application are reliability improvement of input data, reduction of an input burden of a registration institution, and a speedup of information disclosure. 2) We accessed HIS (Hospital Information System) of a registration institution, RIS (Radiology Information System) in order to improve the precision of follow-up survey with surviv … More al information from clinical information, examination information, and dosage information. 3) We could customize a multi-institutional database like a protocol of a registration institution so that buried differences of a purpose of a database, data item, data cord, and structure. On the developed VPDB (Virtual Private Database), we could register cases on multi-institutional database as if on database for an institution. 4) We developed the learning system which can show the treatment plan that was optimized for an individual case from survival analysis information of the past. 5) Furthermore, we saved image data as well as text data and could search and were able to grasp the actual situation of detailed radiotherapy. 6) From accumulated enormous radiotherapy case registration and structure investigation of a registration institution, we analyzed on-site problems of current radiotherapy and made a guideline under the present conditions.We established the radiotherapy results improvement methods using web-based database.
