COT-7 Online supports for opening of the tumor treating field

Background: EF-14 trial showed the efficacy of tumor treating fields (TTF), and TTF was approved as a standard therapy for glioblastoma in Japan. In TTF opening, Device Support Specialist (DSS) explains how to use it for the patient and the family. Because there is no DSS in Yamaguchi prefecture, DSS has to come to our hospital across other prefectures. On the other hand, COVID-19 is still spreading and it is sometimes tough to move from a big city to countryside. Here, we would present the experiences of TTF opening with online DSS support. Method: From June 2020, Zoom was used for 4 patients, and from June 2021, iPad/Face-Time was used for one patient. TTF was introduced via online DSS support with direct support from our nurse in our out clinic. After that, initial times of TTF change were performed via online DSS support in patient’s home. Two patients who used Zoom had trouble to connect to internet, however finally completed with relative helps.Conclusion: Online medicine should be absolutely spreading in country sides. Now, we change from Zoom to iPad, because the old patients in country sides were hard to use internet utility. We should make efforts to provide patients more brief methods of online support.
