COT-02 The opening of tumor treating fields with online support system

Background: EF-14 trial showed the efficacy of tumor treating fields (TTF), and TTF was approved as a standard therapy for glioblastoma. In TTF opening, Device Support Specialist (DSS) should explain how to use it for the patient and family. However no DSS does always stay in our Yamaguchi prefecture, and DSS has to come to our hospital across other prefectures. On the other hand, COVID-19 infection is still spreading and it is sometimes tough to move from a big city to countryside. Here, we would present the first experience of TTF opening with online DSS support. A case report: A 68 years old man had right hemiparesis. MRI showed multiple lesions in the left hemisphere, and biopsy showed glioblastoma. After 1 month from chemo and radiotherapy, TTF was introduced. DSS from Tokyo explained how to use TTF via PC camera with TV monitor. A skilled neurosurgeon and special nurse also helped them in front of him. His head and the attached array were well checked from DSS with PC camera moving around him. Everything was smooth and he started TTF. Conclusion: Online medicine should be absolutely spreading. In countryside, it is hard that DSS comes to our hospital from a big city. TTF opening could be favorable via online system with skilled medical stuffs.
